Amazon, the company, is in the satellite launch business. It is behaving like a sovereign nation. Of course, launches, orbits and time in service have to be coordinated with the military. Not knowing what's up there would be a hazard to navigation.
As I have already mentioned here, the easiest and the cheapest way to deal with space junk ( dead sats ) is to send them to the atmosphere of Earth and make them burn down there.Sending them to the Sun will require a lot of energy that might prove too expensive to sustain. But the idea might make sense if dead sats are first collected (empty starship?), eventually processed to retrieve materials and electronics and then de-orbited in bulk for the sun to burn.
Was that 23 tons before or after they burned all their liquid fuel?

How does the albido of aluminum oxide compare with the albido of titanium oxide, or residue from burnt carbon fiber composites?The large number of re-entries of satellits from megaconstellations may cause a second ozone hole.
Air pollution from reentering megaconstellation satellites could cause ozone hole 2.0
When defunct satellites burn in the atmosphere, they leave behind chemicals that could damage the ozone layer and affect how much light Earth absorbs.www.space.com
#CZ5B debris found near the border of Malaysia and Indonesia, that is more than 1200km from the splash location disclosed by CMSA
Fairing of Long March 5B Y3 rocket (CZ5B) found in Philippine . Expecting briefings from CNSA/CMS. Source: share.api.weibo.cn/share/32535354…
So, CZ-5B recap: signficant debris falls in Kalimantan, Indonesia and Sawarak, Malaysia (both on Borneo). No casualties or property damage reported, but debris is near villages and a few hundred metres either way could have been a different story.
A SpaceX representative says a team will travel to Australia after the recent discovery of a large piece of space junk on an outback property, saying the incident is "within the expected analysed space of what can happen".
#Aeolus reentry #operations, day 1: first manoeuvre successfully completed!
Today saw the largest thruster firing in #Aeolus’s five years in orbit:
Altitude lowered by ~ 30 km
Burn duration: 37 min 24 secs
️Fuel consumption: ~ 6 kg

Remember, Aeolus was not designed for this ending. It was ‘meant’ to naturally fall in an uncontrolled reentry – its propulsion system and fuel reserves were not designed to allow the satellite to be controlled down to the required altitudes for a fully controlled reentry.
Related video that explains more:With this campaign, ESA engineers and operators are pushing the satellite to the limits of what it can do.
The success of this first manoeuvre bodes well for the rest of the campaign.

CONFIRMED in the early hours, #Aeolus reentered Earth’s atmosphere on 28 July at around 21:00 CEST above Antarctica.
