NASA confirms Perseverance Mars rover got its first piece of rock

NASA confirmed on Sept. 6 that its Perseverance Mars rover succeeded in collecting its first rock sample for scientists to pore over when a future mission eventually brings it back to Earth.

"I've got it!" the space agency tweeted, alongside a photograph of a rock core slightly thicker than a pencil inside a sample tube.

The sample was collected on September 1, but NASA was initially unsure whether the rover had successfully held onto its precious cargo, because initial images taken in poor light were unclear.

After taking a new photo so mission control could verify its contents, Perseverance transferred the tube to the rover's interior for further measurements and imaging, then hermetically sealed the container.

"This is a momentous achievement and I can't wait to see the incredible discoveries produced by Perseverance and our team," NASA administrator Bill Nelson said in a statement.

Thomas Zurbuchen, the associate administrator for science, likened the achievement to the first samples of rock taken from the Moon, which are still invaluable to researchers today.

Perseverance's sampling and caching system is the most complex mechanism ever sent to space, with over 3,000 parts.

Its first target was a briefcase-sized rock nicknamed "Rochette" from a ridgeline that is particularly interesting from a geological perspective as it contains ancient layers of exposed bedrock.

Perseverance uses a drill and a hollow coring bit at the end of its 7-foot-long (2-meter-long) robotic arm to extract samples.

After coring the rock, the rover vibrated the drill bit and tube for one second, five separate times.

This procedure is called "percuss to ingest" and is meant to clear the lip of the...
