How to Bring Mars Sample Tubes Safely to Earth (Mars News Report)

NASA's Perseverance Mars rover is filling sample tubes
with rocky material on the Red Planet as the agency works
on the next steps to get them safely back to Earth.
The Mars Sample Return campaign would bring samples
collected by the Perseverance rover to Earth for detailed
study. The campaign involves an international
interplanetary relay team, including the European Space
Agency (ESA). These samples could answer a key
question: did life ever exist on Mars?
Aaron Yazzie, who works on the Mars Sample Return
campaign, explains the work being done at NASA's Jet
Propulsion Laboratory to ensure the safe return of the
sample tubes.
