NASA’s Psyche probe is about to slingshot around Mars at 12,000 mph

NASA's Psyche spacecraft is preparing for a close encounter with Mars that will help send it deeper into the solar system on its way to the metal-rich asteroid Psyche. On Friday, May 15, the spacecraft will pass just 2,800 miles (4,500 kilometers) above the Martian surface while traveling about 12,333 mph (19,848 kph). During the flyby, Mars' gravity will alter Psyche's path and increase its speed, reducing the amount of propellant needed for the long mission ahead.
