"Overall, the report is full of bad news that is good news."
At least, that's one of the findings from the 2024 Space Environment Report published by the European Space Agency (ESA) on July 23. The report offers an accounting of satellites and debris accumulating in Earth's orbit. ESA's latest report, which has been published annually since 2017, is like a census for space activities and shows how bad the problem is becoming. According to its data, there are more than 35,000 objects being tracked by surveillance networks, with approximately 26,000 being pieces of debris larger than 4 inches in size.
The report suggests that despite an improved effort to mitigate this massive amount of space debris, the junk has continued to pile up. So much so, in fact, that we are creating "an unsustainable environment in the long-term," the report says.
Just this week, SpaceX revealed the 6,200 satellites in its Starlink megaconstellation have had to make almost 50,000 collision-avoidance manuevers over the past year, dodging junk and debris in low-Earth orbit. The company also had an on-Earth near-miss in May, after debris from one of its Crew Dragon spacecraft landed throughout the mountains of North Carolina, including on private residences.

Grippers sabotaging their potential for grip in space is a win in my book.
Setting myself on fire deprives my employer of his ability to exploit my labor, yes, but it does also set me on fire, Sir.
If it is impossible to get into space because of garbage, we will stop dreaming about space exploration, and instead realize that we are stuck on Earth and that we need to take care of it.
We didn't take care of the earth before we could reach into space so I'm not buying that
We will have to. Or we will die.
Plenty of current and future Earth observation satellites are at risk as well.

Well, those are in higher orbits where there's a lot more space. LEO is the biggest problem because it's got the majority of all satellites and debris and it's relatively small. GEO
is also pretty crowded, but almost all the satellites there are flying in neat synchronization, because, well, Geostationary orbits.Edit:
Maximum debris concentrations can be noted at altitudes of 800-1000 km, and near 1400 km. Spatial densities in GEO and near the orbits of navigation satellite constellations are smaller by two to three orders of magnitude.
