By saving on the weight of the passengers and life support, a mission can bring much more scientific instruments, or use a much cheaper launcher. That's not even taking into account the savings obtained by taking a longer route (gravity assist, etc...) and the risk of losing the crew's lifes. There isn't much reason to do a crewed mission to an asteroid right now. | |

In the end, they spend 1 day on Apophis and admit that "Obviously, the scientific part of the stay of one or two astronauts on Apophis will have to be reduced to a minimum, leaving an important role for media and communication constraints." | |

| May 12, 2024 at 19:58 | comment | added | Michael MacAskill | “This new ability”? People have been climbing out of space craft since 1965. And these suits aren’t anywhere near as capable as those used on the ISS for decades. | |
