Mars Sample Retrieval Lander (SRL)

The Mars Sample Return (MSR) mission collects and sends samples of Martian rocks, soil, and atmosphere to Earth for detailed chemical and physical analysis. The Sample Retrieval Lander (SRL) will play an important role in the safe return of Mars rock and atmosphere samples to Earth, delivering crucial spacecraft and hardware to Mars: the rocket that will launch samples from Mars, the two helicopters, and a robotic arm to transfer the samples into the rocket.
