Getting our fingers on intact Mars rocks, rigorously saved and protected from contamination, might be invaluable to planetary science,” Razzell Hollis advised Newsweek. They’ll must watch for the Mars Pattern Return (MSR) mission, which isn’t anticipated to launch from Earth until at least the late 2020s. Still, the trip must be worth the wait.
