NASA's Mars Rover Fails to Collect Its First Sample

Friday the Perseverance rover on Mars made its first attempt to collect a rock sample and seal it in a tube, reports NASA. But unfortunately, the data "indicate that no rock was collected during the initial sampling activity..." "The sampling process is autonomous from beginning to end," said Jessica Samuels, the surface mission manager for Perseverance at NASA's Jet Propulsion Laboratory in Southern California. "One of the steps that occurs after placing a probe into the collection tube is to measure the volume of the sample. The probe did not encounter the expected resistance that would be there if a sample were inside the tube." The Perseverance mission is assembling a response team to analyze the data. One early step will be to use the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) imager - located at the end of the robotic arm - to take close-up pictures of the borehole. Once the team has a better understanding of what happened, it will be able to ascertain when to schedule the next sample collection attempt. "The initial thinking is that the empty tube is more likely a result of the rock target not reacting the way we expected during coring, and less likely a hardware issue with the Sampling and Caching System," said Jennifer Trosper, project manager for Perseverance at JPL "Mars keeps surprising us," adds the rover's Twitter feed. "We're working through this new challenge. More to come." Space.com points out this wasn't a make-or-break moment for the rover, since it's still carrying 42 more sampling tubes. And the plan has always been to leave the sample tubes on the surface of Mars, where they'll be retrieved later by future Mars missions.
