@crypticcelery Objects in low orbits decay quickly (at 500 km within a few years). This is even more true for debris. Once you get to the higher altitudes, the satellites will stay in orbit for hundreds or even thousands of years. So the problem is not the volume (which grows with r^3), but rather the lifetime. If you leave too much stuff up there, it will be circling the Earth for so long that collisions are inevitable.

It is very important to ask three questions:

1.) How do spaceship and satellite launches impact our environment, in particular the #thermosphere?

mastodon.social/@HistoPol/1132

2.) Who is the main culprit of this unsustainable development in orbit? (see below)

mastodon.social/@HistoPol/1111

(Translation: see #AltText)

3.) How do we combat it?

Unfortunately, I missed this protest. But good to know that #BruceGagnon and others are bringing attention to the #MilitarizationOfSpace!

Oct 24 'Maine Space Conference' protest news release

Bruce Gagnon: "The #MaineSpaceConference is promoting the militarization of space. Efforts are being made to test #hypersonic missiles at the former #LoringAirForceBase. #bluShitAerospace is receiving funding from the U.S. #SpaceForce to launch 'dual use' (military/civilian) mini-satellites into dangerously congested #LowerEarthOrbit. [#LEO].

"Promises of lots of jobs, little to no #environmental impacts, and peaceful exploration of space are the standard claims made at a myriad of potential new launch sites the #USMilitary is exploring around the world.

"The U.S. and #Israel have been blocking a #SpaceWeaponsBan treaty (#PAROS) at the United Nations for more than 25 years.

"Our nation cannot afford to pay for a new expensive arms race in outer space."

Musk's #satellites 'blocking' view of the #universe

by Georgina Rannard
September 18, 2024

"#RadioWaves from #ElonMusk’s growing network of satellites are blocking scientists’ ability to peer into the universe, according to researchers in the Netherlands.

"The new generation of Starlink satellites, which provide fast internet around the world, are interfering more with #RadioTelescopes than earlier versions, they say.

"The thousands of orbiting satellites are 'blinding' radio telescopes and may be hindering astronomical research, according to Netherlands Institute for Radio Astronomy (#ASTRON).

"#SpaceX, which owns Starlink, has not replied to a request from BBC News for comment.

"The satellites provide broadband internet around the world, often to remote places, including challenging environments like Ukraine and Yemen.

"They are also used to connect remote areas of the UK to fast internet. In 2022 tests showed that Starlink could deliver internet speeds four times faster than the average, according to the Department for Digital, Culture, Media and Sport.

"But astronomers say this comes at a cost.

"'Every time more of these are launched with these kinds of emission levels, we see less and less of the sky,' Professor Jessica Dempsey, director of ASTRON, told BBC News."

Are We Going to Mess Up Outer Space Too?

As nations jockey for military edge in orbit, there is a growing threat from above

by Daniel Munro Updated 8:49, Jun. 19, 2024

"Over the past decade, however, space has become much more contested and harder to govern. Nearly 1,000 private companies now offer space-based products and services. Expanding #SatelliteConstellations offer better internet access in remote and developing communities, enabling more people to access online health care, work remotely, and connect with family and friends. Space technologies also support better weather and climate monitoring, improve navigation and transportation logistics, and enhance agricultural productivity through the use of land- and water-quality sensors. All this has contributed to a space economy with an estimated value of $447 billion (US), on a trajectory to reach $1 trillion by 2030. And missions focused on exploration and scientific discovery are expanding—including the US-led Artemis program that aims to land human beings on the moon for the first time in over fifty years.

"But this new space age poses substantial risks. #OrbitalDebris from inactive satellites, discarded rocket parts, and anti-satellite #weapons tests threatens the infrastructure on which our social and economic well-being now depends, as well as the lives of astronauts working on space stations. In addition to the 30,000 objects large enough to track, there are an estimated 1 million debris fragments—between one and ten centimetres in diameter—that are too small to be picked up by ground-based radar and surveillance networks. Experts put the likelihood of future collisions between these objects at near certainty, with potential for cascading and catastrophic damage including entire satellite communication systems being taken out and larger debris fragments falling to #Earth and threatening lives and #ecosystems."

No Toxic Rockets for Maine

Who We Are

"#NatureLovers opposed to building #polluting #RocketLaunch sites in #Maine. We monitored & resisted the rush to pass 'emergency' legislation to create a public-private partnership for rocket launch sites in our state. In April, 2022, #LD1923 was signed into law by Gov. #JanetMills after passing the House 'under the gavel' i.e. without a voice vote.

Military Use

"LD 1923's sponsor Rep. Daughtry insists that no military uses are planned for rocket launch sites in Maine. But in every location we've studied, the same promises were made and not kept.

"In# Kodiak, #Alaska 20 years ago one launch site was built with developers claiming it was only for civilian purposes. There are now multiple sites there being used by the #Pentagon and the #IsraeliMilitary. Meanwhile, the jobs that were promised for the project never developed. Sites are staffed when launches happen by outsiders who leave after the event. Only custodial and security staff jobs are available to the local community.

"Recently a #SpaceX launch of satellites saw 40 of them fall out of the atmosphere due to a #SolarStorm. In their statement about their response to the incident, SpaceX stressed their close cooperation with the Pentagon:

"The #Starlink team commanded the satellites into a safe-mode where they would fly edge-on (like a sheet of paper) to minimize drag — to effectively 'take cover from the storm' — the #SpaceForce’s 18th Space Control Squadron and LeoLabs to provide updates on the satellites based on ground radars.

#Toxic Fallout

"When rocket launches go wrong -- as they frequently do -- #chemicals rain down on land and sea as highly toxic materials burn up.

"In case of fires at the rocket launch site, large scale storage of #PFAS foam is to be expected. Maine already has a severe #PFASContamination problem on #Agricultural land across the state."

#Protest outside & inside of #MaineSpaceConference

By Bruce Gagnon,
Published on Organising Notes, 7 November 2023

"About 200 people attended the conference which was intended to ramp up the establishment of Maine’s campaign to enter ‘the space race’.

"The event began with Dr. Terry Shehata, Executive Director of the Maine Space Grant Consortium, introducing a NASA headquarters speaker who was described as ‘Our sugar daddy, we need to keep him happy’. The NASA representative talked alot about reaching students across Maine and beyond in order to build their support for everything space. After all, in just a few years these students will be taxpayers and the aerospace industry wants to ensure that their generation supports massive federal spending for Moon and Mars missions and the #militarization and #nuclearization of space.

"The aerospace industry calls it an investment. I learned this years ago at a similar conference at the #KennedySpaceCenter in Florida. In a workshop on ‘updating the center’s museum’, the director told the assembled they were retro-fitting the museum on a Mars theme. He bragged that they brought in thousands of Florida students each year that ‘would soon be taxpayers’. That is now a national NASA organizing strategy to keep the aerospace funding pipeline humming for years to come. Get to the students and sell them on the ‘wonders of space’. Let’s all be astronauts!

"Maine State Sen. Mattie Daughtry (D-Brunswick) led a plenary panel discussion that promoted the joys of the space gold rush by promising loads of good paying jobs, little-to-no #environmental impacts from launching rockets, and heavy emphasis on teacher and student recruitment. Daughtry was the prime sponsor of the bill in the state legislature to create the Maine Space Corporation with its 17-member board that heavily represents the aerospace industry.

"Almost all the plenary speakers talked about the wonders of #MaineWilderness that enables us to see the starry #NightSky. Sadly none of the speakers noted the irony that due to the space gold rush, launching thousands of #satellites is ruining the dark view. #Astronomers complain that it is becoming near impossible to do astronomical research because of long-strings of blinking #satellites in the night sky.

[...]

"While many of the speakers made grand claims about jobs to come from #Maine’s participation in the space gold rush, the evidence is otherwise. One of the other speakers at the conference talked about space manufacturing becoming increasingly done via robotic and computerized operations. This would increase ‘productivity’ and increase profit but reduce the need for so many workers.

"Other places where #RocketLaunch sites have been created like #KodiakIsland, #Alaska and #RocketLab in #NewZealand promised lots of jobs (which never materialized) and only civilian launches. In both those cases virtually all launches so far have been for the US Pentagon. In the case of Rocket Lab it has been taken over by #LockheedMartin.

"Many of the people attending the Maine Space Conference were investors who are eager to ride the space rocket to grab profit and notoriety. Like any gold rush the long-term truth turns out to be quite different than the original sales pitch promises.

"It is incumbent upon Maine citizens to pay attention to this issue before taxpayers in the state get handed a huge bill for costs that were never made clear during this early round of pie-in-the-sky promotion."

@amgine @mastodonmigration From ~500km, you're look at around 10 years for orbital decay to drag them down, and during that time if they knock out something else, that will start it's own decent journey, so things quickly get exponential.

Longer term the real concern that really hasn't been addressed is the atmospheric pollution caused both by launch engines themselves (which are absolutely filthy and wildly resource intensive) and by the burning up of debris both in launch and disposal. There are large quantities of metals, plastics and propellents being burned in a completely uncontrolled manner in the upper atmosphere, at quantities which are already having a measurable impact on the atmosphere itself. The more junk Elmo yeets to orbit, the worse this is getting, and there is zero long-term plan for managing any of this - indeed, the plan such as it exists at all is explicitly to use our atmosphere as completely unfiltered, uncontrolled incinerator.

The fun doesn't stop there as the ISS operates around 400km, below the Elon Zone, so all the shit he creates will impact on the ISS, as well as the numerous other essential missions that need lower orbits.

Elon Musk's #Starlink satellites light up night sky

by Story by Lydia Wilson, October 24, 2023

"A trail of bright lights have been spotted in the night skies in the south of England.

"The lights are not Father Christmas making a trial flight in his sleigh or a new constellation - but Starlink satellites launched by Elon Musk's #SpaceX.

"The chain of lights can bee seen for the rest of the week."
