Regular Commutes Extending 656 Feet Or More Are Expected
NASA's Mars 2020 Perseverance rover performed its first drive on Mars March 4, covering 21.3 feet (6.5 meters) across the Martian landscape. The drive served as a mobility test that marks just one of many milestones as team members check out and calibrate every system, subsystem, and instrument on Perseverance. Once the rover begins pursuing its science goals, regular commutes extending 656 feet or more are expected. "When it comes to wheeled vehicles on other planets, there are few first-time events that measure up in significance to that of the first drive," said Anais Zarifian, Mars 2020 Perseverance rover mobility test bed engineer at NASA's Jet Propulsion Laboratory in Southern California.

Reported Hard Landing May Have Created Explosive Results Several Minutes After Touchdown
SpaceX-watching is one of the most exciting pursuits in the aerospace world. Between their extraordinary successes, and their occasional explosive disappointments, watching their efforts is rarely disappointing. On Wednesday, March 3, Starship serial number (SN10) successfully completed SpaceX’s third high-altitude flight test of a Starship prototype from a SpaceX test site in Cameron County, Texas. Similar to the high-altitude flight tests of Starship SN8 and SN9, SN10 was powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN10 performed a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.
