Perseverance’s first major successes on Mars – an update from mission scientists

In the short time since NASA’s Perseverance rover landed in Mars’ Jezero Crater on Feb. 18, 2021, it’s already made history. At the moment, Mars and the Earth are on opposite sides of the Sun, and the two planets cannot communicate with each other. After working nonstop for the past 216 Martian days, the science teams are taking the first real break since the mission started. We are two members of the Perseverance team, and with the rover hunkered down for the 20 days of conjunction, it is the perfect time to step back and reflect on the mission thus far. This Conversation piece was created by Dr. Briony Horgan, EAPS, and Dr. Melissa Rice, Western Washington University.

A Mars Rover Explored a Wasteland and Found an Oasis

Millions of miles away, on the surface of Mars, inside an enormous crater, a little NASA rover is taking some pictures. The view is quite stunning there—miles of undisturbed cinnamon terrain scattered with pebbles and boulders, with silky dunes where the craggy bedrock doesn’t peek through. But when the rover, named Perseverance, sent the photos back home from the crater, known as Jezero, scientists saw something more. Dr. Briony Horgan is cited in this article from The Atlantic.
