Los Angeles, Dec 12 (UNI) NASA's Orion spacecraft returned to Earth after making an uncrewed mission around the moon. After 25.5 days in space and a 2.24-million-km journey around the moon, the Orion spacecraft splashed down off the coast of the US state of California at 12:39 pm Eastern Time (1739 GMT) on Sunday. Orion was launched onboard NASA's Space Launch System rocket on November 16 from NASA's Kennedy Space Center in Florida for the Artemis I mission. The Artemis I flight test is an uncrewed mission around the moon that will pave the way for a crewed flight test and future human lunar exploration as part of NASA's Artemis lunar program.
