NASA’s Perseverance Mars rover has some rocks stuck in its throat.
Perseverance drilled and collected its sixth Red Planet rock sample late last month, but the car-sized rover hasn’t been able to seal up the titanium tube containing the material yet.
Perseverance landed in February 2021 inside the 28-mile-wide Jezero Crater, which harbored a lake and river delta billions of years ago. The rover has two main mission goals: hunt for signs of ancient Mars life and collect and cache several dozen samples. This pristine Martian material will be returned to Earth, perhaps as early as 2031, by a joint NASA/European Space Agency campaign.
Everything went smoothly until Perseverance transferred the sample, which was already inside its titanium tube, into the “bit carousel,” a rotating, wheel-like structure on the rover’s chassis. Sensors recorded resistance unexpectedly early during this step, suggesting a blockage of some sort. “However, this is the first time we are doing a debris removal, and we want to take whatever time is necessary to ensure these pebbles exit in a controlled and orderly fashion,” Jandura added.
