NASA should consider relaxing some of its guidelines governing how to prevent the contamination of planetary bodies during robotic and human missions, according to a report released Friday.

Why it matters: NASA wants to be sure that if life is eventually found elsewhere in our solar system, it isn’t the result of contamination from our own world.

Why an all-female spacewalk took so long

As NASA aims to make spaceflight more inclusive and equitable, outdated ideas about women and their fitness for certain aspects of spaceflight still persist.

Driving the news: During a press briefing ahead of the historic all-female spacewalk on Friday, NASA's acting associate administrator for human exploration Ken Bowersox suggested that it took this long for two women to go on a spacewalk together in part because women's bodies aren't as fit for spacewalking as men's.
