So, on again, off again. Starliner cancelled. Space-X rescue mission. No, Starliner will be used, Space-X on hold. and over and over. NASA can't make up their minds. I feel for the two astronauts caught in the middle. And now Space-X has had their schedule delayed, for all things, environmental concerns. Noise, and that tower cooling water is being allowed to runoff into a nearby stream and might contain contaminants such as mercury.
In other related news, China launched a rocket with StarLink-equiv satellites, and it blew up. They tried again, and it blew up. The huge problem here is that they are launching into a higher altitude than StarLink or the ISS. The debris field from the two explosions had put hundreds of pieces of debris into orbits above the ISS with no way to remove them. Space-X launches into an altitude lower than the existing StarLink sats or ISS, so if there is a problem, it all falls back to earth under gravity and burns up. Currently, the StarLink sats have to make collision avoidance corrections for debris as many as 140 times a day per sat. As debris from the Chinese crap starts to fall lower, an even bigger mess. Scientists are saying if more debris accumulates, you can reach a cascading condition where it's not "if" there is a collision, but an ever increasing number of collisions making Low Earth Orbit unusable, and travel thru the field next to impossible to leave earth. And China is not as of yet even acknowledging the problems they created.
