A small pile of pebbles clogs the operation of the Perseverance Mars Rover.
Rover collecting rock samples to finally return Earth, After a mission team nicknamed “Issole” extracted the core from the rock, it began to struggle on December 29th.according to NASA blogThe problem occurred with a device that moved and stored the drill bit and sample from the Rover’s drill arm to the carousel in the Rover’s chassis.During the transfer, the sensor in the rover recorded a higher than normal amount friction At an unexpected point in the process.
The rover shut down and sent an alert back to Earth. The operator requested more data from Rover, but the perseverance response took about a week because the discrepancy between Mars Day and Earth Day limited the data transfer rate. When the data arrived, the team ordered Rover to act as his mechanic by removing the drill bit and undocking the drill arm to photograph his internal organs.
The resulting image revealed the problem: a small pile of pebbles in the carousel. These debris fell from the sample during the transfer process and prevented the drill bit from being properly placed within the bit carousel.
Carousels are designed to work in the presence of debris, but NASA operators are spending time looking for solutions.
“This isn’t the first curve Mars has thrown at us, it’s the latest,” wrote Louise Jandura, chief sampling and caching engineer at NASA’s Jet Propulsion Laboratory, in a blog post. “One thing we’ve found is when engineering challenges are hundreds of millions of miles away (Mars is now 215 million miles away from Earth).[346 million kilometers]), It will be rewarded to be thorough over your time. I’m going to do that here, “she added.
The Perseverance Rover landed on Mars on February 18, 2021. It is exploring the Jezero Crater, once a river delta. The goal is to take rock and soil samples to assess for signs that the crater once lived. Rover has equipment that can perform in-flight analysis, but it is hoped that future Mars missions will be able to retrieve Rover’s rock samples and return them to Earth.
This isn’t the first time the Perseverance team has had to overcome sampling problems.Rover First attempt to collect rock samples We’re screwed.But Rover quickly succeeded Collect a pair of rock samples Quickly and continuously.
