How likely is it for NASA to miss some mid-sized piece of space debris, resulting in said space debris impacting the ISS? Just curious.
Keep up to date with the Space calendar 2022: Rocket launches, sky events, missions and more!
We need a moon as soon as possible.So, sooner or later, there are going to be really serious occurrences which add so much to mission costings that they will become impracticable and space exploration will be costed out?
Or does this make transfer to Moon base essential at an early date?
CatI am envisaging that, if we continue to pollute space environs, and that if we wish to build Moon base(s), let alone Mars manned landing(s), there will be conflict between manned flights and increased pollution.
If we wish to 'visit' Moon and/or Mars with view to bases " twere best done quickly ". If left too long, pollution will interfere with base traffic. Base traffic will be considerably more expensive than local garbage precursors.
Flecks of paint et al. will not destroy the station, just make pits. The 5+ cm pieces are tracked and avoided. The problem is the 1-4 cm pieces we are blind to but will trash any module(s) they hit, think along the lines of a small, non-explosive artillery shell kind-of-thing. The 5+ guys are relatively rare (miss distances up to a mile or so trigger newsworthy avoidance), but the number of smaller pieces is only estimated, but the danger from them is still MUCH smaller than the danger of the Russians deliberately disabling the station out of pique.Depends on what you consider, "mid-sized". The Space Surveillance Network can track objects as small as five centimeters in diameter (in low Earth orbit). Smaller objects, down to flecks of paint can still cause serious issues with orbiting satellites/space stations. The US Shuttle had to frequently replace it's windows due to such impacts.
Do I not understand correctly, that a larger than expected space object has knocked part of the JWST about a bit?Flecks of paint et al. will not destroy the station, just make pits.
The Webb mirrors are especially especially fragile and susceptible to damage from debris. This Webb debris was very small, likely the size of a smoke particle or even smaller. And the damage is mainly miniscule misalignment and warping of the exquisitely engineered and aligned mirror segments. Does not translate to the experience of grossly large damage to earth orbiting satellites, something you can push a soccer ball through.Do I not understand correctly, that a larger than expected space object has knocked part of the JWST about a bit?
How large does one expect them to be?
Also very expensive. One wonders whether any insurance company would take them on? I would agree that meteoroids can always be larger than you expect.The Webb mirrors are especially especially fragile and susceptible to damage from debris.
Fortunately, this does not seem to have caused serious damage.
