Donald Trump’s “20-Point Plan” could provide a path to end the Gaza genocide, but it is limited by a lack of details and the uncertainty of whether the U.S. is willing to enforce it on Israel.
Ieri, durante una trasmissione su La7, si è svolto un acceso confronto tra Marco Grimaldi e Davide Parenzo. Come spesso accade, Parenzo ha finito per commentarsi da solo. Nel momento in cui si discuteva della possibile liberazione di Marwan Barghuti, Parenzo lo ha definito un “terrorista”.
Eppure, tutti sanno che Marwan Barghuti è un parlamentare palestinese, incarcerato dal 2002 senza prove concrete a sostegno delle accuse che gli sono state mosse. È stato membro dell’OLP, l’Organizzazione per la Liberazione della Palestina, e dirigente di Fatah. Le imputazioni nei suoi confronti non sono mai state suffragate da fatti, ma questo non ha impedito che restasse in carcere per oltre vent’anni.
Il paragone tra Barghuti e Nelson Mandela nasce in modo naturale. Quando Mandela era membro dell’ANC, l’African National Congress, movimento che lottava contro l’apartheid, possedeva un carisma straordinario. Durante la sua lunga detenzione, l’ANC attraversò momenti di divisione, ma una volta libero Mandela riuscì a riunire il popolo sudafricano.
Allo stesso modo, Marwan Barghuti rappresenta una figura capace di unire il popolo palestinese, ed è proprio per questo che non viene liberato. Persino Benjamin Netanyahu lo ha ammesso apertamente: la sua liberazione potrebbe “unire tutti i palestinesi”, un rischio che il potere israeliano non vuole correre.
A un certo punto, Parenzo ha sostenuto che Mandela “non ha mai fatto la lotta armata”. Forse sarebbe il caso che studiasse meglio la storia. Mandela non fu arrestato perché faceva volare le colombe o portava fiori ai colonialisti bianchi, ma perché faceva parte del braccio armato dell’ANC, l’Umkhonto we Sizwe, “La Lancia della Nazione”.
Mandela partecipò ad azioni di sabotaggio, a scontri armati con il braccio militare del regime dell’apartheid, a dirottamenti di linee ferroviarie, a boicottaggi e ad attacchi simbolici contro le strutture del potere coloniale interno. Accanto a lui si distinsero figure come Chris Hani, Winnie Madikizela Mandela, Solomon Mahlangu, Joe Gqabi, Ashley Kriel e Steve Biko, intellettuale e leader del Movimento della Coscienza Nera, brutalmente assassinato dalla polizia sudafricana nel 1977. Tutti furono protagonisti di una resistenza che combinava la forza delle idee con la determinazione della lotta concreta contro un sistema disumano.
Mandela ebbe “la fortuna” di essere arrestato e condannato a 27 anni di carcere, invece di essere ucciso come molti dei suoi compagni. Durante la detenzione, si trasformò progressivamente nella coscienza morale del Sudafrica, simbolo di un popolo oppresso ma non piegato.
Dopo la sua liberazione, Mandela divenne il volto della riconciliazione nazionale. Ma questo non cancella le sue origini nella lotta armata e nella resistenza politica. Al contrario, testimonia la sua evoluzione da combattente a statista, da rivoluzionario a mediatore.
Spesso viene romanticamente descritto solo come “l’uomo del perdono”, come se la sua grandezza derivasse da una mitezza innata. In realtà, Mandela aveva conosciuto il male, la tortura, l’umiliazione e la perdita, ma scelse consapevolmente la via della riconciliazione come atto politico e morale, non come resa.
Perdonò senza dimenticare, perché sapeva che il futuro del Sudafrica non poteva fondarsi sulla vendetta, ma sulla giustizia. La sua missione fu quella di ricostruire un Paese devastato, mantenendo aperta la mano anche verso i sudafricani bianchi, per ricucire ciò che la violenza aveva spezzato.
Romanzare la sua storia, ignorando la parte più dura e radicale della sua lotta, significa falsificare la verità storica.
Il caso di Marwan Barghuti è diverso solo in apparenza. È accusato di terrorismo per fatti mai provati, ma la sua colpa è politica: rappresenta l’unità e la resistenza del popolo palestinese. Ed è questa la vera ragione per cui rimane in prigione.
Vorrei dire a Davide Parenzo: se non conosci la storia di Mandela, è meglio studiarla o tacere. Dopo il carcere, Mandela divenne un uomo di pace e di dialogo, ma non rinnegò mai la lotta da cui era partito. E quando il Sudafrica si liberò dall’apartheid, cercò di reinserire il Paese nel contesto internazionale, mantenendo però sempre un profondo sostegno alla causa palestinese, fino agli ultimi giorni della sua vita.
Non va dimenticato che Nelson Mandela figurava ancora nelle liste dei “terroristi” del Mossad, della CIA e di diversi servizi segreti europei fino a due anni prima della sua morte, avvenuta nel 2013.
Questo la dice lunga su come il sistema colonialista continui a etichettare come “terroristi” coloro che si oppongono alla violenza e all’ingiustizia.
It's becoming increasingly clear to me that Reflect Orbital's fucking stupid giant mirror satellite, with absolutely NOTHING useful to offer, which will cause countless safety issues, ecological disasters, and destroy the night sky, is going to launch.
A bunch of astronomers and I have sent out a fact sheet about them to a bunch of journalists, but very few are going to write about this. So, let me try posting it all here.
Here's what I know about Reflect Orbital and all the downsides:
Reflect Orbital (RO) reflectorbital.com/ wants customers to pay them to reflect beams of sunlight down from orbit. This is called “sunlight as a service.”
Their initial plan is for each beam to be several times as bright as the full moon and at least 5 km in diameter on the ground.
Due to the high speed needed to orbit Earth, each satellite will shine on one point for only a few minutes at most (Reflect Orbital says 4 minutes thetundradrums.com/reflect-orb…)
Reflect Orbital is building satellites that beam sunlight to Earth on demand. Starting in 2025, customers can order a 3-mile of light in 4-minute chunks
If the mirrors cannot be stowed between pointings every 4 minutes, they will sweep across the ground as they move between one target and the next.
At their proposed size, a single RO satellite is orders-of-magnitude too faint to power a solar panel on the ground, thus many would be required to power solar panels. youtube.com/watch?v=lkjyeI0ykG…
RO has applied to the FCC for their first satellite launch in mid-2026, stating they plan to launch thousands of these satellites orbitaltoday.com/2025/07/31/st…
Profitez des vidéos et de la musique que vous aimez, mettez en ligne des contenus originaux, et partagez-les avec vos amis, vos proches et le monde entier.
Although the ground illumination from the first satellite will be much fainter than the Sun’s, looking at the satellite with binoculars or a telescope could actually damage your eyes, similar to looking at a partial solar eclipse. articles.adsabs.harvard.edu/fu…
Beams of light sweeping across the sky at night can cause problems for pilots and drivers. It has the potential to be a substantial distraction, and risks disrupting night vision, particularly with multiple beams. This could be risky around airports and could lead to accidents, similar to laser strikes on aircraft. faa.gov/newsroom/laser-strikes…
Having thousands of RO satellites in orbit would lead to frequent bright flashes all over the sky for any observer on the ground. Even millisecond flashes of light at night have been shown to disrupt human circadian rhythms. journals.plos.org/plosone/arti…
Ocular light sensitivity is the primary mechanism by which the central circadian clock, located in the suprachiasmatic nucleus (SCN), remains synchronized with the external geophysical day.
Have you noticed how bright the sky is the last few nights with the very bright nearly-full moon? Now imagine a point source 4x brighter, and moving across the sky. That's what they want to do
Astronomy requires dark skies to see faint celestial objects. Due to scattering of light along the beam, anytime an RO satellite is above the horizon, it would disrupt any ground-based optical astronomy telescopes in the area. digitalcommons.usu.edu/smallsa…
We are in the process of developing a system which redirects the incoming sunlight to a stationary ground target after sunset and before sunrise. One of the purposes is to extend operating hours of solar-farms to after sunset and before sunrise.
Similar to astronomical observing with a full moon in the sky, it would restrict observations to only the very brightest handful of stars and planets. This would cause the vast majority of astronomy research to be impossible while one or more of these satellites is above the horizon.
Directly shining the beam onto a large telescope (anywhere within 5km of a large telescope facility) could damage sensitive research telescope camera equipment, which are calibrated to study faint celestial objects
All life on Earth – including humans, migrating birds, pollinating insects, plankton in the oceans – depends on the natural day-night cycle of light and darkness. Many hundreds of scientific studies document the importance to ecosystems and agricultural crops of protecting that natural cycle. Bird migrations, pollination, plant growth, and animal behaviors could all be disrupted by reflected sunlight from orbit.
Large reflector cross-sections also mean a much higher collision risk from micrometeorites and non-trackable orbital debris. Using typical rates sciencedirect.com/science/arti… at 625km altitude (the orbit RO proposes to use), such reflectors could expect hundreds of micrometeorite and debris impacts each year, quickly degrading the reflector and creating more diffuse and larger beams.
There are already solutions right here on Earth to many of the problems “sunlight as a service” purports to solve. This approach is simply a reckless and inefficient use of Earth orbit, a precious and finite resource.
This list of facts was developed by me and a bunch of very concerned astronomers. If you're a journalist interested in writing a news article about this, please look up my university email and contact me, and I'll be happy to chat.
What can you do? The FCC never opened up a comment period on RO's filing for launch, so there's no official way to protest. They may open it up later? Absolutely no info on that.
DarkSky International is working on a petition to be delivered to RO's misguided investors, I will share that as soon as its public.
Most important: tell people about all the downsides of "sunlight as a service." The world needs to know how incredibly bad this idea is.
This article by two astronomers details many of the points I just talked about and more ways that Reflect Orbital's plan will never be feasible, just detrimental: now in The Conversation Australia, perfect timing: theconversation.com/a-us-start…
To me the big point remains economic: how can these satellites possibly pay for themselves? I just don't see how the whole thing is supposed to work financially. Starlink may be awful for the environment, but it's at least plausible they could get enough mobile phone subscribers to make the system viable. There's just no way reflecting light from orbit onto solar plants is a feasible alternative to building more solar plants and battery storage.
surely if any other country that isn’t the one which allowed it to happen has a problem, they could take it out with a missile?
It’s a private company’s property, so it’s not state vs. state violence and therefore couldn’t be seen as an act of war, only an act of self-preservation.
Another brilliant idea to waste investor money and get rich on the way until the project fails.
"It would eventually be followed by about 4,000 satellites in orbit by 2030"
That's another problem. As we don't have enough satellites in orbit and plans for more already. Ah meh, adding another 4000 here, another 6000 there doesn't matter, right?
Nowadays, i'd rather have "brain on demand" than "sunlight on demand".

I am indebted to my friend and colleague Naz for coining the phrase "Tholian Web Bros" to describe orbital startups like this that are poisoning our night sky.
"It remains to be seen whether Reflect Orbital’s project will get off the ground. The company may launch a test satellite, but it’s a long way from that to getting 250,000 enormous mirrors constantly circling Earth to keep some solar farms ticking over for a few extra hours a day."
Primarily designed to suck up huge amounts of money from gullible investors. It worked for AI, with disastrous consequences.
Every Springfield wants to beat Shelbyville in the race for the monorail.
@startswithabang The big thing is at the end -we already have solutions such as inexpensive LiFePO4 storage to couple with renewables. This is really simple stuff.
@startswithabang I wonder if people in places like ancient Egypt bitched about the pointlessness of the gods demanding them waste all their effort and resources building small mountains for them.
"Next thing you know they're gonna want us to put giant mirrors in space to reflect the sun so they can pretend to control that too."
All the various other places...
"Why we building these stupid statues pointing out to sea when we're all dying?"
@startswithabang I originally thought they were trying to build a satellite death-ray but it seems more like they’re proposing to build a satellite derp-ray.
@startswithabang This is one of the dumbest ideas I have ever heard of, in a life of technology work, which has the highest dumb idea particle ("stupidons") flux of any industry.
We come up with these grand ideas and never even consider the environmental cost. Both the planet and the orbit atmosphere are already a trash can. Learn how to be responsible first.
@startswithabang To the best of my knowledge, no one has answered my question-what if a third party government objects to the deployment of this technology, can they demand that the mirror does not shine on their territory? Would they be justified in destroying the mirrors if they shine where they are not wanted(after a warning of course)?
Have I mentioned how much I like Nicole Mortillaro? Great article, includes quotes from @JohnBarentine (there were various good reasons why she didn't interview me for this one, but fortunately a lot of other astronomers besides me are really worried about Reflect Orbital's thoughtless plan)
@JohnBarentine I don't know if it will do anything, but I emailed the company today and asked them to educate themselves more about light pollution, recommended two books.
@JohnBarentine Thank you Prof Sam! As someone passionate about fighting against light pollution, I'm really thankful that you have brought it to my attention and you are working against it. I think another angle you can take here, as someone in Saskatchewan, if these mirrors actually did work, do you think farmers would really pay for this? (they already have lights on their machines and don't need to illuminate the entire field all at once).
@JohnBarentine so what happens when one of them gets hit by a starlink satellite or something similar? 7 years of bad luck and falling shards of a mirror plummeting towards unsuspecting individuals on the ground…
What happens to animals that require dark for their nocturnal lives, or migrating birds, or cetaceans that rely on celestial navigation. What is the effect on plants that need a photoperiod in order to enter or break dormancy ? Do we really need more junk in orbit? Do we need to breathe the molecular waste as obsolete satellites burn as they reenter our atmosphere? This is a project with blinders on, with a singularity of purpose and little consideration for other earth inhabitants.
woah I’m sorry WHAT. Thank you so much for talking about this I had no idea. Jesus why are we so determined as a species to invest untold resources on terrible solutions to small problems when we have good solutions to huge problems just begging for cash??? This is absurdity.
@grb090423 @Pourroy Truly. Just a handful of rich people with total disregard for the wellbeing of the ppl they depend on and the maturity level of 12 year olds who think SPACE MIRROR COOL.
I really thought that this was an elaborate hoax or prank you were pulling, a broad satire of capitalism that no one could possibly believe, but apparently this is really trying to exist.
Can you imagine how many people's eyes will be damaged by accidental entry into the field of view of an amateur telescope? I had to blink away for several minutes seeing the full moon through my 30 cm telescope while I was "space walking" with a slow slew speed and a one degree field of view. I can't imagine a near point source 4x brighter. Actually, it would be similar to seeing a bit of the sun through the telescope. Very dangerous.
@RegGuy Are you sure a passing Reflect Orbital "sunlight as a service" satellite-mounted mirror needs a telescope or binoculars to permanently damage an eye? @sundogplanets
@RegGuy @xdej I linked a research paper about that in the gigantic thread above, written by an optometrist and a physicist. It's based on the Znamya space mirror, but is applicable to the latest round: articles.adsabs.harvard.edu/fu…
I can't even wrap my head around why somebody would want to do this as a service. (I don't need you to write out an explanation; I don't want to take up your time that way. I will look it up.)
I think this is one of the stupidest things I have seen proposed recently. Next thing you know we'll have LED billboards in space or... whatever.
That's not the future I want! I want dark nights and to be able to see the Milky Way from my house, and for birds not to get lost in their migration paths and healthier sleep and... I guess I want to time travel back to the 1200s, when there were no satellites and no electric lights. Grrrr.
@arisummerland > this is one of the stupidest things I have seen proposed recently. Next thing you know we'll have LED billboards in space or... whatever
This! Sunlight-as-a-Service is like something out of Idiocracy. What's shocking is not that one nutter envisioned it (some of the blue skies brainfarts I come up with are just as far out), nor that a subculture of true believers formed around it. But that people in control of serious resources took it seriously.
@strypey That says a lot about the people in control of the resources -- meaning it says a lot about how out of touch they are with reality, at least in my mind.
Having read a little bit about it now, I sort of understand why somebody might think it would work and why they might think it might replace coal or natural gas or whatever to keep lighting up the world (and I continue to think it is a ludicrous concept). Yet it's still the space equivalent of filling up your entire yard with fragile tchotchkes that you're probably going to run over with your lawnmower. Bad idea.
Yes, but we need to keep reminding ourselves and others that at scale, ‘deorbiting’ satellites is just another way of saying ‘pumps metals and rare earths into the upper atmosphere’ and there’s no way that could go wrong is there?
But I do not have a mass breakdown for what Reflect Orbital is trying to launch - they have been inconsistent in reporting the size of the claimed mirror. So I cannot say how much they would contribute to atmospheric pollution.
As @sundogplanets wrote, the question is how much of a mess the group makes before this all stops.
We’re already there though… the Starlink model is to orbit and then ‘deorbit’ satellites by the thousands. The standard ‘space guy’ response to any concerns has become some version of ‘that’s ok, we’ll just be deorbiting them all, so nothing’s permanent’ which is, of course, bullshit.
how do we stop rockets from being launched commercially? Maybe there's ones we need for weather and exploration, but profit driven rockets, how can regular people stop them?
I'm late to this thread, but can confirm that at our radio observatory, even a brief flash of reflected sunlight would permanently damage or destroy our receivers. This would be a total logistical nightmare, especially as we are near a decently large population center.
Genuine question, do (professional) astronomers in 2025 still rely on visible light to make their discoveries? It seems like such a small part of the electromagnetic spectrum. If so, what makes this part of the spectrum more useful to science than any other?
I'm asking as somebody who knows absolutely nothing about modern astronomy.
I guess power demand for AI datacenters is driving this snake oil. Seems like a stupid idea and my guess is someone’s money will disappear here. As long as they’re taking money from big tech and not actually going to build it, I’m fine with it.
This is another piece of surreal madness. Musk's satellite network comes from the same mental pathology. A couple of years ago, I witnessed 19 satelittes reflecting the sun while separating from their launch vehicle, visible from my 'dark sky' deck in Newfoundland, but actually happening hundreds of kilometres in the sky above The Netherlands. 19 of nearly 9,000 as of September of this year. Musk plans 32,000 more to complete his so called 'megaconstellation'.
Astronomers have for decades been understandably loud about the problems that the congestion in our skies poses for earth based observatories. That's bad enough, but real risks are increased for every human occupied space craft, particularly as collision particles scatter with bullet speeds in random directions through and across the orbits of everything else up there.
Earthlings, those in cities, towns and rural areas are also at increasing risk when sky-junk falls among us--not always in the ocean or in farm fields.
Where are the people and institutions for the protection of the skies above us (and by extension, those living underneath). For now we learn that Musk's marbles in space are falling to Earth every day.
"University of Maryland. Scientists Denny Oliveira, Eftyhia Zesta, and Katherine Garcia-Sage have uncovered compelling evidence that solar storms—those explosive, radiation-spewing tempests from our nearest star—are cutting short the orbital lives of Starlink satellites.... 'It’s not just about satellites falling faster—it’s about them falling unpredictably,' said co-author Eftyhia Zesta. 'And unpredictability is the last thing you want when you have thousands of satellites overhead'.” (space.com/spacex-starlink-sate…)
Can I ask just which mental institution these RO people escaped from?? Jeezus... as if our earth's skies aren't congested enough with Musk's space junk.
howdy fam! If you still have those fact sheets I’d love to take a look.
I don’t have a ton of experience so I might not be the right person to cover it, but I confess the concept of startup getting funded to build an orbital cancer laser has captured my curiosity.
this is gobsmacking, but expected from the US right now.
Even a stoner kid with a few plants in their cupboard knows about how important the day night cycle is. It's the difference between bushy growth, sticky-icky, and dead plants
OMG. First I've heard of this and it's bar nothing the dumbest thing I've heard in the last decade. And I've heard a lot of stupid shit the last decade
You mean to tell me that all you have to do is attach a flashlight to a balloon and dip shits will send you loads of money?
I wonder if the angle is to sue everyone with a solar collector claiming that they are either stealing their sunlight or bypassing their sun light using actual sun light.
How are they going to prevent us from using the Moon Light?
The farming industry should wake up over this because this could cause crops to go ape shit with wacky light cycles. Unfortunately they are on their own bat shit journey.
Or perhaps it's some naming dibs/rights before the fusion reactors come online. (In the next 10 years.)
It seems people are constantly schemeng ways to charge rent on everyone on the planet.
I'd love to see you repeatedly reference them as FSGMs, without expanding the initialisation, and have it widely published and commonly referred to, before some "journalist" actually does their job and prints what it means. 🤪
Be interesting to know what their comms surface looks like. TX/RX relative position with each other? Any dependence on GNSS for on-ground acquisition? Near-earth satellites are not so far away as to be immune to a directional antenna and some well crafted RF noise.
Similarly, if their beam was narrower, a large concave mirror on earth reflecting energy back to them may implement a stressor, esp if they have sensors on board for which that excess is not anticipated. Book a ray, setup mirror, DoS
@datarama Add a bit of technology to these "sunlight satellites" & could these be converted to a low earth orbit laser platform? thedebrief.org/threat-of-war-i…
In addition to the hazards created by the metallic chaff from Elon Musk's Starlinks that suffer from "Rapid Unscheduled Disassembly" ie they explode regularly; how much easily weaponizable stuff do we want in space?
here’s an idea, instead of thousands of expensive and polluting satellites, which are suggested to deliver very dim facsimiles of daylight for limited time periods, why don’t we just switch *all* of the clocks in the world 12 hours forwards? That way the sun comes out at night when it’s dark, instead of during the day when it’s already light? Problem solved! 😂
it does feel very hyperloop though, so probably won't amount to anything more than a great big vaccum to suck cash out from investors into certain individuals' pockets
A US company wants to launch a satellite in 2026 that acts as a mirror and reflects sunlight back to Earth. Thousands more are planned. Criticism is increasing.
Astronomen alarmiert: US-Satelliten sollen Sonnenlicht zur Erde reflektieren
Eine US-Firma will 2026 einen Satelliten starten, der als Spiegel Sonnenlicht zur Erde reflektieren soll. Geplant sind tausende mehr. Die Kritik wird lauter.
Get a very potent spotlight. Point it at the CEOs bedroom windows for 4 minutes periods several times a night. Call it “Sleep disorder on demand”. See how he likes it… 😒
@Paulatics @bougiewonderland I can send you a less swear-filled summary version, just let me know (apologies for the swears, it really helps me deal with it all!)
ever since I saw you mention this yesterday I've been seeing articles about it! Two in my google feed, one last night and one this morning. Hopefully lots of noise gets made about how awful this would be.
It's not clear to me why techbros keep trying to re-introduce ideas that have already been tried and discarded. Hyperloop is just a rehash of 19c pneumatic rail, already tried and discarded, and just as predictably successful (that is, NOT). So-called 'moonlight lamps' -- giant lamps that illuminated very large areas -- were discarded well over a century ago, too. This seems like just a rehash of that already failed idea. Don't any of these 'smart' guys read?
A US company wants to launch a satellite in 2026 that acts as a mirror and reflects sunlight back to Earth. Thousands more are planned. Criticism is increasing.
It's worth scrubbing through the EEVblog video she links.
TL, DW - Dave's simple back of the envelope math reveals the sunlight spreads out to a few hundred MILLIwatts / m^2. Not even enough energy to run the power inverters the solar cells are connected to. Recovered energy == zero.
@martinvermeer @tml I'll just say that if they have thousands of satellites, they will have to be at many different altitudes. Something at 600km altitudes is easily visible for a couple hours after sunset or before sunrise, which is fully dark - that's when you see all the Starlink satellites.
18x18m is their first satellite size. Large enough to be damaging to your eyes if it's reflecting sunlight and you accidentally look at it with binoculars. I'd say that's a really big problem.
@tml But as I was arguing, it is visible _well beyond_ astronomical twilight, which is when the Sun is less than 18 degrees below the horizon, and still illuminates the top of the atmosphere. I know, I have observed satellites for years.
Edit: as the name implies, 'astronomical twilight' is before the sky is dark enough to make astronomical observations, i.e., really dark.
@martinvermeer But during Finnish summer nights there is more light anyway than what such a tiny orbital space mirror would provide.
The plans of this company are crazy enough as such, no need to use wild exaggerations to fight them. Just simple calculations are enough to demonstrate that it is a scam. I hope.
@tml It depends. A satellite at 600 km altitude is visible in the zenith well after/before astronomical twilight, in Finland, e.g., all through the night for the summer half of the year. But yes, the central parts of winter nights should be safe.
I remember recently reading an article about... I think it was China, might be wrong... talking about putting up satellites with what I imagine would be significant solar arrays, and then downlinking the power to ground stations as focused microwave beams.
I don't know if that technology is actually feasible, but even then you'd still have to be careful; it might not "blind" astronomers per se, but wouldn't it mess with radio astronomy?
What makes you think it's really going to happen? To me it just feels like a grift.
As a side note, from time to time I do solar cooking. I've made multiple cookers with various materials. Space blanket mylar is inexpensive, but it tends to break down after a few months. You can use thicker mylar that works for like two years, but it weighs a lot more, so would cost more to launch. UV in space would be worse.
@number6 They have a factory where they are building satellites. They paid a buttload of money to the FCC to file for launch. They paid a buttload of money to SpaceX to have a spot on a rocket. They are doing it.
FML. Last week they wanted to block out the sun. This week they're reflecting it around. These supervillains could at least make up their minds and focus on one evil plan at a time.
People with such dumb ideas tend to be pretty dumb. They tend to ignore the experts they hire and "move fast and break shit". But moving fast and breaking shit *IN SPACE* (as well as *AT THE BOTTOM OF THE OCEAN*) doesn't, um, work very well?
I'll be surprised if they can deploy without trying 50 times.

Ciao a tutti 😀 Condividere il progetto su cui si sta lavorando può essere un buon modo per infondere coraggio a chi voglia cimentarsi nell’arte del cucito.
È poco che cucio, ma la passione si è trasformata in lavoro in poco tempo pur non cancellando come fosse il mio mondo in bianco e nero, senza ago e filo nella macchina o nelle mani, il mondo prima di adesso.
‘Cucire’ era mia nonna che aggiungeva i polsini alle giacche ormai troppo corte.
‘Cucire’ era un’amica speciale che per regalo di nozze mi scriveva una lettera chiusa da una busta cucita a mano con la scritta ‘Auguri!’, ricamata sul cartoncino.
‘Cucire’ era la sarta della merceria del paese che trasformava i pantaloni lisi dei miei figli in panta-toppe.
‘Cucire’ era tante cose, ma non ero io.
Oggi condivido invece i progetti su cui sto lavorando: delle camice di seta con taglio a kimono. Ancora mi chiedo come io mi sia ritrovata qui. Ma mi sento a casa. Una casa cucita su misura.
E voi, in che progetto state mettendo le mani? Rattoppate? Ricamate? Cucite scarpe scucite? Cucite per sopravvivere?
lgsp@feddit.it grande! Intanto buon lavoro 😀 che tecniche utilizzi? Sei super informat@ o hai voglia di conoscere di più? Se hai piacere condivido molto volentieri le tecniche che ho imparato 😀 possiamo anche aprire una discussione per ampliare le conoscenze sul rammendo, creativo e non! Fammi sapere 😀
Per i rammendi avevo cominciato con la tecnica del video YouTube del post linkato. Però di fatto si cedevala cucitura. Allora ho cominciato a fare il mezzo punto indietro, per calzini e altro. Però ho notato che spesso si rompevano di nuovo vicino alla cucitura, segno che ormai il tessuto era debole credo. Allora per rapidità adesso faccio una semplice imbastitura nella parte interna (prendo i nomi da qui )
Per i jeans e altri lavori più "belli" tento di fare il punto indietro, anche se la mia precisione e regolarità lasciano a desiderare, ma di solito il risultato è soddisfacente.
Una cosa che vorrei capire meglio è come e quanto legare all'inizio e alla fine: ho sempre la sensazione di non fare le cose bene e che poi tutto si possa aprire.
Nota finale: ormai ogni volta che vari in hotel, se c'è, mi porto a casa il kit cucito... Risorsa preziosissima!
lgsp@feddit.it buonasera a te! Dunque da quel che leggo mi sembra importante condividere con te qualche punto che ritengo essenziale per la buona riuscita di un rammendo (che sia o meno creativo).
Rammendare necessita del criterio di similarità 😀
Innanzi tutto capiamo che tessuto stiamo trattando: un tessuto a maglia, elastico o un tessuto fermo non elastico?
Nel primo caso dovremo intervenire con un ago idoneo, a punta arrotondata per non compromettere le maglie, filo idoneo (meglio se della stessa natura della fibra del capo in questione: se lana, allora userò filo di lana, se cotone, cotone, ecc) ed infine: punto idoneo, ovvero un punto elastico.
Per il secondo caso, idem come sopra, ma adattandoci alla fermezza del tessuto. Un buon ago ben appuntito, un filo della stessa fibra e un punto fermo.
La riparazione si fa partendo da un centimetro oltre la linea di demarcazione fra tessuto liso o compromesso ed il tessuto sano, ovviamente sulla parte non compromessa.
Se ripari bene, hai la possibilità di non sprecare materiale inutilmente e di far durare più a lungo la tua riparazione. Oltre che migliorare la tua autostima;)
Per le toppe vale lo stesso criterio: stesso tessuto e grammatura del tessuto da rattoppare. E cucitura idonee.
Io ho da poco (ri)cominciato con prove, finendo un progetto di cucitura di mantello simil-fantasy iniziato anni fa partendo da un altro comprato finito, principalmente con l'obiettivo di imparare a farne altri per amicu e cosplay. Sarei curioso di continuare per capire se è una cosa che fa per me, perché a primo impatto mi appassiona molto e dà soddisfazione, quindi spero di riuscire a realizzare altri progetti e vedere come va sul lungo termine ;D
matteob@mastodon.uno che bel progetto! Come hai trasferito il modello su carta? Ho recentemente scoperto una tecnica interessante! Potremmo aprire una discussione per condividere le tecniche per clonare i vestiti 😀 che ne dici?
eh la verità è che non l'ho trasferito su carta, ho fatto dei "carta"modelli direttamente con un altro tessuto, poggiandoci sopra il mantello finito e ricalcando dove potevo, aggiungendo i margini extra e le linee cucite a occhio o tirando rette di congiunzione per poi provare a fare reverse-engineering delle cuciture in vista senza scucire nulla 😅 Decisamente poco professionale quindi non saprei se sono adatto a condividere tecniche 😛 Il metodo che hai scoperto quale sarebbe?
Personalmente la userò fra poco per clonare una camicia che mi è stata commissionata. L’imperativo era non devastarla poiché ancora in ottimo stato, ma usarla per creare una nuova camicia come regalo di Natale 😀
Ogni tecnica è buona se per te va bene 😀 questa precisione del video mi incuriosiva perché una volta eseguito il cartamodello sei a più di metà dell’opera 😀 sembra molto preciso!
Profitez des vidéos et de la musique que vous aimez, mettez en ligne des contenus originaux, et partagez-les avec vos amis, vos proches et le monde entier.
eccomi di nuovo! Grazie per il video, molto interessante e sì mi sa che prenderò l'idea in prestito (mooolto semplificata) per altre prove, intanto devo dire che sono talmente tanto alle prime armi che non ho ancora usato la carta apposita per fare i cartamodelli: perché c'è un tipo di carta in particolare da usare vero? Anche solo per la grandezza... come si chiama e dove si trova di solito da comprare?
Perdona le tempistiche ma solitamente ci metto quel tot a rispondere 😅

👉 Messaggio da copiare OGGETTO: Urgente – Richiesta di supporto per la Global Sumud Flotilla sotto attacco Gentilissimi, vi scrivo con urgenza a nome della Global Sumud Flotilla, che si trova attualmente in acque internazionali in missione umanitaria. Nelle ultime ore le imbarcazioni sono state ripetutamente prese di mira da droni e ordigni, con attacchi che mettono in pericolo la vita di tutti i partecipanti. La GSF ha già registrato esplosioni nelle vicinanze delle imbarcazioni e in alcuni casi è stata colpita, con danneggiamenti riportati, causati da potenti bombe sonore e sostanze urticanti. Chiediamo con urgenza: •Un’immediata presa di posizione pubblica per condannare questi attacchi. •La protezione dei partecipanti da parte delle istituzioni internazionali. •La pressione diplomatica e politica sui responsabili per fermare queste azioni illegali. Con urgenza, [Tuo nome] A nome della Global Sumud Flotilla
All eyes on Gaza. All eyes on Global Sumud Flottiglia – Scioperi e mobilitazioni in corso – Aderiamo
I Giuristi Democratici sono impegnati in tutte le iniziative di solidarietà e di mobilitazione contro i crimini di guerra e contro l’umanità che il governo Netanyahu ed il suo esercito stanno mettendo in atto in Palestina e in Cisgiordania. Aderiamo ed appoggiamo gli scioperi indetti nei posti di lavoro per il 19 settembre ed il 22 settembre , e sosteniamo tutte le iniziative in corso contro ogni complicità con il governo di Israele, contro la consegna di armamenti, innanzitutto.
L’invasione militare di Gaza, che fa seguito ad ormai numerose azioni militari assolutamente inammissibili messe in atto da IDF (i bombardamenti sui civili, sui negoziatori, su paesi terzi, l’appropriazione di terre, le violenze dei coloni) e le affermazioni di prepotenza e dei governanti israeliani sul futuro della popolazione palestinese sono incredibilmente tollerate o ignorate da buona parte dei governi europei, incluso il nostro, e supportate apertamente dall’amministrazione Trump. Sono azioni criminali contro i palestinesi, contro noi tutti e contro il diritto internazionale.
Per questo stiamo con i lavoratori in sciopero, con gli attivisti della Sumud Flottiglia, con gli attivisti che stanno nelle piazze, nei porti e nelle stazioni, a manifestare e cercare di boicottare l’economia di guerra di un governo criminale.
Continuiamo il nostro impegno, giuridico e sociale, insieme ed a supporto di chi si sta mobilitando in questi giorni, per terra e per mare, per fermare il genocidio in atto, e tenteremo di portare anche nelle aule di giustizia la nostra adesione alla giornata del 22 settembre, facendo inserire nei verbali di udienza le nostre dichiarazioni di sostegno.
Giuristi Democratici -19 settembre 2025
Qui sotto la dichiarazione che molti colleghi si apprestano a verbalizzare in udienza il 22 settembre, a sostegno dello sciopero.
Oggi molte persone incrociano le braccia per protestare per quanto sta accadendo a Gaza e in Cisgiordania, per il crimine di genocidio, per i crimini di guerra, per i crimini contro l’umanità che il governo israeliano sta commettendo impunemente ed anzi con l’appoggio di molti altri governi tra i quali il nostro. Credo che sia giusto, in senso etico ben prima che codicistico, che proprio nelle aule dove si “fa giustizia” si ricordi e si condanni quanto sta accadendo, nell’auspicio che quei crimini, tra i più gravi commessi dal 1945 in poi sul nostro pianeta, possano essere un giorno processati. E, come giurista democratic*, mi auguro, anche in queste aule

This would cause the vast majority of astronomy research to be impossible while one or more of these satellites is above the horizon.
Directly shining the beam onto a large telescope (anywhere within 5km of a large telescope facility) could damage sensitive research telescope camera equipment, which are calibrated to study faint celestial objects

These are too numerous to even try to list.
All life on Earth – including humans, migrating birds, pollinating insects, plankton in the oceans – depends on the natural day-night cycle of light and darkness. Many hundreds of scientific studies document the importance to ecosystems and agricultural crops of protecting that natural cycle. Bird migrations, pollination, plant growth, and animal behaviors could all be disrupted by reflected sunlight from orbit.

This! Sunlight-as-a-Service is like something out of Idiocracy. What's shocking is not that one nutter envisioned it (some of the blue skies brainfarts I come up with are just as far out), nor that a subculture of true believers formed around it. But that people in control of serious resources took it seriously.

That says a lot about the people in control of the resources -- meaning it says a lot about how out of touch they are with reality, at least in my mind.
Having read a little bit about it now, I sort of understand why somebody might think it would work and why they might think it might replace coal or natural gas or whatever to keep lighting up the world (and I continue to think it is a ludicrous concept). Yet it's still the space equivalent of filling up your entire yard with fragile tchotchkes that you're probably going to run over with your lawnmower. Bad idea.

But I do not have a mass breakdown for what Reflect Orbital is trying to launch - they have been inconsistent in reporting the size of the claimed mirror. So I cannot say how much they would contribute to atmospheric pollution.
As @sundogplanets wrote, the question is how much of a mess the group makes before this all stops.

We’re already there though… the Starlink model is to orbit and then ‘deorbit’ satellites by the thousands. The standard ‘space guy’ response to any concerns has become some version of ‘that’s ok, we’ll just be deorbiting them all, so nothing’s permanent’ which is, of course, bullshit.

"You want nuclear? We own the uranium mines."

in reply to Prof. Sam Lawler • • •This is another piece of surreal madness. Musk's satellite network comes from the same mental pathology. A couple of years ago, I witnessed 19 satelittes reflecting the sun while separating from their launch vehicle, visible from my 'dark sky' deck in Newfoundland, but actually happening hundreds of kilometres in the sky above The Netherlands. 19 of nearly 9,000 as of September of this year. Musk plans 32,000 more to complete his so called 'megaconstellation'.
Astronomers have for decades been understandably loud about the problems that the congestion in our skies poses for earth based observatories. That's bad enough, but real risks are increased for every human occupied space craft, particularly as collision particles scatter with bullet speeds in random directions through and across the orbits of everything else up there.
Earthlings, those in cities, towns and rural areas are also at increasing risk when sky-junk falls among us--not always in the ocean or in farm fields.
Where are the people and institutions for the protection of the skies above us (and by extension, those living underneath). For now we learn that Musk's marbles in space are falling to Earth every day.
"University of Maryland. Scientists Denny Oliveira, Eftyhia Zesta, and Katherine Garcia-Sage have uncovered compelling evidence that solar storms—those explosive, radiation-spewing tempests from our nearest star—are cutting short the orbital lives of Starlink satellites.... 'It’s not just about satellites falling faster—it’s about them falling unpredictably,' said co-author Eftyhia Zesta. 'And unpredictability is the last thing you want when you have thousands of satellites overhead'.” (space.com/spacex-starlink-sate…)

I wonder if the angle is to sue everyone with a solar collector claiming that they are either stealing their sunlight or bypassing their sun light using actual sun light.
How are they going to prevent us from using the Moon Light?
The farming industry should wake up over this because this could cause crops to go ape shit with wacky light cycles. Unfortunately they are on their own bat shit journey.
Or perhaps it's some naming dibs/rights before the fusion reactors come online. (In the next 10 years.)

Similarly, if their beam was narrower, a large concave mirror on earth reflecting energy back to them may implement a stressor, esp if they have sensors on board for which that excess is not anticipated. Book a ray, setup mirror, DoS

in reply to Prof. Sam Lawler • • •It's worth scrubbing through the EEVblog video she links.
TL, DW - Dave's simple back of the envelope math reveals the sunlight spreads out to a few hundred MILLIwatts / m^2. Not even enough energy to run the power inverters the solar cells are connected to. Recovered energy == zero.
This is Nikola / Theranos level fraud.
Prof. Sam Lawler
Unknown parent • • •@martinvermeer @tml I'll just say that if they have thousands of satellites, they will have to be at many different altitudes. Something at 600km altitudes is easily visible for a couple hours after sunset or before sunrise, which is fully dark - that's when you see all the Starlink satellites.
18x18m is their first satellite size. Large enough to be damaging to your eyes if it's reflecting sunlight and you accidentally look at it with binoculars. I'd say that's a really big problem.
Martin Vermeer FCD
Unknown parent • • •@tml But as I was arguing, it is visible _well beyond_ astronomical twilight, which is when the Sun is less than 18 degrees below the horizon, and still illuminates the top of the atmosphere. I know, I have observed satellites for years.
Edit: as the name implies, 'astronomical twilight' is before the sky is dark enough to make astronomical observations, i.e., really dark.
Tor Lillqvist
Unknown parent • • •@martinvermeer But during Finnish summer nights there is more light anyway than what such a tiny orbital space mirror would provide.
The plans of this company are crazy enough as such, no need to use wild exaggerations to fight them. Just simple calculations are enough to demonstrate that it is a scam. I hope.

I don't know if that technology is actually feasible, but even then you'd still have to be careful; it might not "blind" astronomers per se, but wouldn't it mess with radio astronomy?

As a side note, from time to time I do solar cooking. I've made multiple cookers with various materials. Space blanket mylar is inexpensive, but it tends to break down after a few months. You can use thicker mylar that works for like two years, but it weighs a lot more, so would cost more to launch. UV in space would be worse.
