· Föderation EN Mi 18.09.2024 15:31:18 @sundogplanets I am naive about spacecraft. Do these satellites have a way to be brought safely back to earth, or are they stuck in space until they break apart and fall to earth? |
Föderation EN Mi 18.09.2024 15:35:49 @volcano @sundogplanets since every idiot with too much money wants to put a ridicioulus amount of satelites in orbit i think the Situation is only getting worse. |
Föderation EN Mi 18.09.2024 16:10:01 @volcano @sundogplanets they have thrusters to avoid other satellites and debris, and they carry enough propellant to deorbit at end of life and burn up safely in the atmosphere |
Föderation EN Mi 18.09.2024 16:14:03 For the most part YES. Most of these satellites have ion thrusters which should allow them to be deorbited on command. The orbit these are on will also naturally decay after 5yrs if the satellites stop occasionally boosting their orbits. This is all a bit uncharted air control problem the so it's probably a bit dangerous to bring a lot down at once. |
Föderation EN Mi 18.09.2024 16:55:30 @nullagent @volcano @sundogplanets Yes, they will mostly burn up in the upper atmosphere and are unlikely to kill people via direct impact. However, these large numbers of satellites will deplete the ozone layer and kill and blind people via increased rates of cancer and cataracts. The chances of SpaceX/Elon Musk caring are ... I dunno ... close to zero. Even if government regulation demands that they do something about it, I expect they will simply defy the law. |
