kerbiloid Posted November 15, 2021 Share Posted November 15, 2021 Let them check settings. The default limit of the debris is 250. Quote Link to comment Share on other sites More sharing options...

Shouldn't be too much of a problem as long as it isn't on a path with the ISS. Even then there's always avoidance maneuvers. Quote Link to comment Share on other sites More sharing options...

Even then there's always avoidance maneuvers. 1500+ trackable objects. >2000kg of total debris. In a crossing orbit above ISS. Debris will tend to deorbit over time, crossing ISS altitude. This was an unforced error, or intentional. Either choice is bad. Quote Link to comment Share on other sites More sharing options...

Even then there's always avoidance maneuvers. Everything that becomes a cloud of debris above the orbit of ISS will eventually be on the path of ISS as the orbit degrades. Orbital mechanics doesn't take bribes. This will put ISS in the hazard area within a few years. The debris cloud should disperse by then to make the odds of impact low, but there is absolutely zero way to predict or avoid this danger now.

Side question: is there an orbit above ISS that does not degrade? (I thought that once you got high enough, orbits were fairly stable, but it was the (exceptionally thin) remnants of the atmosphere responsible for most degradation of LEO stuff).

When you're up thousands of kilometers above the Earth decay times tend to be in the thousands of years. I think solar wind and the Moon can push stuff around on those timescales.

(or is the magnetosphere sufficient to prevent this?) Quote Link to comment Share on other sites More sharing options...

On the other hand, it incrreases the gas drag on the planet way. *** On the bright side: the ISS future now looks more clear.

That the LeoLabs radar has only tracked 216 so far. They say in the tweet the number will increase substantially. They need to be able to resolve individual objects.
