This Sample Retrieval Lander would carry a small rocket (about 10 feet, or 3 meters, tall) called the Mars Ascent Vehicle to the Martian surface. After using a robotic arm to load the rover's sealed sample tubes into a container in the nose cone of the rocket, the lander would launch the Mars Ascent Vehicle into orbit around the Red Planet. The lander and rocket are part of the multimission Mars …
