In addition to being intelligent and possessing important skills, are there any specific height and weight requirements for Mars astronauts?
For example, a neighbor on my street would like to become an astronaut. However, he weighs approximately 300 pounds.

There is no job "Mars astronaut".

Assuming this is for the US: NASA hires astronauts once in a while, and there are various medical requirements. Height has a strict range from the Soyuz capsules, I'm not sure about weight (it is easier to adjust that than height...), blood pressure has to be fine, and good performance in fitness tests will be expected.

I think that's OK, provided he's eleven feet tall.

How strict are NASAs health requirements? I imagine high but a manned Mars mission would have unique challenges in terms of the extremely long period of isolation. A few years with no option to reach a hospital or specialist clinic means you don't want any signs of a condition that could flare up and need major attention in that time.

Since they haven't selected anyone for Mars, hard to tell. I'd expect it would be a superset of astronaut requirements and Antarctic winter-over requirements.

I meant what are their current requirements for astronauts. I'm interested to know how much emphasis is placed on the risk of developing serious conditions during a mission.

Commander and Pilot Astronaut Duties
Ability to pass a NASA space physical which is similar to a military or civilian flight physical and includes the following specific standards:
  • Distant visual acuity: 20/100 or better uncorrected, correctable to 20/20 each eye.
  • Blood pressure: 140/90 measured in a sitting position.
  • Height between 62 and 75 inches.
Basic requirements for a Mission Specialist include the following:
  • Height between 58.5 and 76 inches.
The requirements would probably be similar to those for the Apollo astronauts. I would suspect that there would be a restriction on 'pre-existing conditions'.
