I spent 15 years in NASA and few more in other such things.  This is an issue
with a lot of study by such folks.  You do NOT, EVER, suggest astronuats or
crew are expendable, or ever put in a situation where every effort to support
their safe return wasn't taken.  The political firestorm from violating those
rules is intense, and one sided.

Far slowrer than an mission suggested by anyone with the possible exception of
