Going stir crazy? Then train like an astronaut, mimic space

In this Feb. 12, 1984 photo made available by NASA, astronaut Bruce McCandless uses a nitrogen jet-propelled backpack, a Manned Manuevering Unit, outside the space shuttle Challenger. Astronaut wannabe Rachel Zimmerman-Brachman, a public engagement specialist at NASA's Jet Propulsion Laboratory, says that isolation is a lot like astronaut training. On Thursday, March 19, 2020, she wrote on Facebook, “Attitude is everything: I'm on an adventure in a confined space with a small crew for a long duration mission, with occasional space walks and resupply missions. Sounds like astronaut training to me.” (NASA via AP)
