Mars rover Perseverance collects new sample after clearing pebble clog

NASA’s Mars rover Perseverance has snagged a sample to replace the material that got stuck in its throat.

Perseverance drilled into a rock called Issole on Dec. 29, 2021, collecting its sixth cored sample since touching down inside the Red Planet’s Jezero Crater last February. But the car-sized rover couldn’t seal up the titanium tube as planned, a problem the mission team soon traced to a few meddlesome pebbles clogging up Perseverance’s sample-handling system.
