Due to units just like the Perseverance rover, we’ve collected and analyzed a ton of samples from the Martian floor. However zero of these samples have returned to Earth. Now, NASA and the ESA are displaying off an answer to this conundrum—an enormous robotic arm.
That is humorous, however it may simply work. The ESA’s Sample Transfer Arm (STA) makes use of two cameras and a variety of sensors to rigorously retrieve small gadgets. Its main job is to drag the pattern tubes out of the Perseverance rover, although it would additionally retrieve any samples left on the bottom by NASA’s Ingenuity helicopters.
The STA will place these samples right into a Mars Ascent Automobile, which can elevate off from the floor to satisfy the ESA’s Earth Return Orbiter. Because the identify implies, this orbiter will return the samples to our planet for research.
On the time of writing, people have solely collected samples from 4 celestial our bodies—the moon, two asteroids, and a comet. Mars would be the fifth on our listing, assuming that this mission is profitable. If the mission is a failure, we’ll have to attend just a few years for a do-over.
In fact, NASA and the ESA don’t anticipate to finish this mission till 2023. The Earth Return Orbiter ought to launch round 2027, whereas the Pattern Retrieval Arm will ship out a yr later.
