NASA is evaluating two less expensive landing methods to retrieve rock, gas, and surface material samples collected by the Perseverance rover on Mars. The samples are set to be returned to Earth by 2029. The agency is considering a 'sky crane' landing method, similar to those used for Perseverance and Curiosity, or a commercial heavy lift vehicle system.

The second option would be to use a commercially provided mass delivery system with commercial partners such as SpaceX or Blue Origin. Nelson said both options involve cleaning Martian dust from the tubes on the planet surface instead of on the return vehicle, and using one of the spare arms on thehelp scientists understand
Perseverance, which landed in February 2021, has been collecting and storing samples in specially designed sealed titanium tubes that are roughly the size of a cigar. Nelson said on Tuesday that by the time the sample collection ends, Perseverance will have collected 30 samples.
