Mars Rover Perseverance Trivia Questions

It uses a radioisotope thermoelectric generator (RTG) that converts heat from plutonium-238 into electricity. This allows it to work day and night, even in dusty conditions.

Jezero Crater was a lake billions of years ago. Scientists believe its delta deposits could preserve signs of ancient microbial life, making it a prime target.

Ingenuity was a small helicopter attached to Perseverance's belly. It made dozens of flights in Mars's thin atmosphere, proving powered flight is possible there.

Its MOXIE instrument converts CO2 into oxygen. This experimental tech could help future astronauts breathe and produce rocket fuel on Mars.

It has found evidence of ancient water, but no liquid water on the surface today. Mars's low pressure makes liquid water unstable; any present is likely briny subsurface seeps.

The tubes are made of titanium and a silica-glass coating, not gold. Gold is used in some spacecraft parts for thermal control, but not for these sample tubes.

The wheels are aluminum but not solid—they have flexible spokes and treads. They're designed to grip rocky soil and avoid the damage that plagued earlier rovers.

Perseverance's microphones have recorded wind and the helicopter, but no confirmed dust devil sound. Dust devils are common, but capturing one audibly hasn't been reported.
