NASA's Perseverance rover has begun making its mark on the Red Planet. Taken on 5 March 2021, this color-calibrated image shows tracks from the rover's first drive on Mars, as well as a lighter-colored area in the background where the ground was scoured by the mission's descent stage rockets.

NASA’s Hubble Space Telescope experienced a software glitch that kicked it into safe mode. The 30-year-old telescope (pictured) appears healthy and engineers are working on a plan to return it to normal operations. Hubble is expected to continue observing and complement discoveries made by its successor, the James Webb Space Telescope, which launches later this year. Image credit: NASA.
Scientists found carbon—an organic compound necessary for life as we know it—in a comet. The discovery was made using NASA’s flying SOFIA observatory. A key question in understanding the history of our solar system is how Earth got its water and organics; our planet likely lost those materials after being internally heated during formation. One possible source is asteroids and comets that formed farther away from the Sun and then collided with Earth long ago.
NASA awarded a contract to Northrop Grumman to help develop the rocket system that will blast samples of Mars off the surface. NASA’s Perseverance rover will collect the samples; it’s up to future missions by NASA and the European Space Agency to retrieve them and bring them back to Earth.
NASA’s InSight spacecraft is preparing to bury the tether leading to its seismometer. Burying the tether will insulate it from Mars’ drastic temperature shifts and help scientists get clearer readings of Marsquakes that will help reveal the planet’s interior.
From The Planetary Society
The names Planetary Society members sent to asteroid Ryugu and back via Japan’s Hayabusa2 spacecraft survived their journey. Hayabusa2 mission officials successfully extracted and accessed the names, which were stored on two MicroSD memory cards—the same type commonly used in cameras and other small electronic devices. The Planetary Society helped Japan’s space agency collect the names in 2013 as part of our Messages from Earth program. The names were also etched into a set of baseball-sized target markers that were dropped on Ryugu to help the spacecraft navigate. Pictured: Hayabusa2 snapped this picture while ascending from its sample grab. The yellow arrow points to one of the target markers it dropped. Image credit: JAXA et al.
Mars and the star Aldebaran are like twins in the evening sky, both shining bright and reddish near the constellation Orion. You’ll see Mars in between Aldebaran and the Pleiades star cluster. In the pre-dawn, Jupiter and Saturn are low to the horizon in the east. Learn more at planetary.org/night-sky.

Wow of the Week
Artist and Planetary Society member Laura J. Lawson makes paintings about landscapes in space using reference imagery from maps made by the United States Geological Survey for NASA. This piece, called Mars 2568, is made with acrylic ink and acrylic paint on polypropylene. "Using the maps as a reference point, I draw out key geologic features first, and then paint over them with acrylic ink," says Lawson. "I like to color outside the lines, so to speak, to imagine the ways these landscapes have changed since the days of Viking and Mariner. I'm so excited to see what kind of art will come from the images of Perseverance." You can find more of her space-inspired artwork at laurajlawson.com/painting.
