NASA's Perseverance rover deploys wind sensor on Mars

NASA's Perseverance rover continues to get up to speed on the Red Planet.

Since Perseverance's picture-perfect landing on Feb. 18, the rover team has been methodically checking out its seven science instruments and various subsystems. For example, Perseverance just deployed its wind sensor, as before-and-after photos captured by the six-wheeled robot's navigation cameras show.

The wind sensor is part of Perseverance's weather station, which is called the Mars Environmental Dynamics Analyzer (MEDA). The instrument will monitor air temperature, humidity, radiation, dust and wind at Perseverance's landing site, the floor of Jezero Crater, a 28-mile-wide (45 kilometers) hole in the ground that harbored a deep lake and a river delta in the ancient past.

Perseverance, the heart of NASA's $2.7 billion Mars 2020 mission, will hunt for signs of life inside Jezero and collect and cache samples for future return to Earth. But that main science work won't start immediately after the rover gets up and running; Perseverance's first big job will be to find an airfield where its little helicopter buddy can take off.

That helicopter, a 4-lb. (1.8 kilograms) craft named Ingenuity, journeyed to Mars on Perseverance's belly. Ingenuity will deploy at the airfield and try to make the first-ever rotorcraft flights on a world beyond Earth, demonstrating technology that could pave the way for a whole new Mars exploration strategy.

Ingenuity's flights will likely take place this spring, with science and sampling work commencing in earnest in the summer, mission team members have said. 

But Perseverance's early days on Mars are far from boring. The rover team has already posted more than 6,300 of the rover's Jezero photos, many of them spectacular high-resolution shots taken with Perseverance's Mastcam-Z camera system. You can find them here. Happy sightseeing!
