NASA Knows This Is the Most Dangerous Part of Going to Mars

Описание: Every Mars documentary focuses on getting there. NASA engineers know the real problem is getting back.

The Mars Ascent Vehicle is the single most critical - and least tested - piece of technology in any crewed Mars mission. No space agency has ever launched humans off another planet. Not once. And if that launch fails, no rescue mission can arrive in time.

This calming long-form space documentary breaks down the full engineering chain that must work perfectly for a crew to return from Mars: manufacturing rocket fuel from thin Martian air, launching from a planet with just enough atmosphere to cause problems but not enough to help, executing an orbital rendezvous with a twenty-minute communication delay, and firing a precise trans-Earth injection burn through a departure window that won't reopen for over two years.

Every link in this chain has never been tested at Mars with human-rated hardware. Every link is a single point of failure. And every failure ends the same way.

This is not science fiction. These are real engineering constraints facing NASA, SpaceX, and every organisation planning human Mars missions. The technology to reach Mars exists today. The technology to leave Mars does not - yet.
