HOWEVER, GETTING THOSE SAMPLES BACK TO EARTH IS A COMPLEX AND CHALLENGING PROCESS. TO HELP WITH THIS TASK, NASA HAS DEVELOPED A ROBOTIC ARM THAT WILL PLAY A KEY ROLE IN THE MARS SAMPLE RETURN MISSION.
The Sample Caching System on board the Perseverance rover includes a seven-foot-long robotic arm equipped with a drill and a coring mechanism. The arm can collect rock samples from the Martian surface, seal them in special tubes, and deposit them in a storage system located inside the rover.
Once the samples are safely stored, the rover will deposit them on the surface of Mars for future retrieval by a follow-up mission. That mission, called the Mars Sample Return campaign, will launch a spacecraft to Mars to collect the samples and bring them back to Earth.
