Does anyone know how they get the sample back to earth uncontaminated? I don't see any information on that in the article and that strikes me as one of the most difficult parts of the process. Wikipedia doesn't have much information and uses a dead link as the source - The spacecraft is planned to depart the asteroid in December 2019, and return samples to Earth in December 2020. The rest of the information I can readily find is in Japanese. Presumably it's pretty similar to the first Hayabusa which is fascinating. https://en.wikipedia.org/wiki/Hayabusa#Recovery_and_return_to_Earth https://en.wikipedia.org/wiki/Hayabusa#Recovery_and_return_t...
