NASA announced Thursday it plans to purchase lunar soil from a commercial company, an effort the agency’s top official said is intended to set a precedent for the transfer of ownership of extraterrestrial material and stimulate a market harvesting resources from bodies throughout the solar system.

Building on a mission canceled last year, NASA is developing a mobile robot named VIPER for launch in 2022 to scout for water ice at the moon’s south pole, the same region where the agency aims to land astronauts by 2024.

SpaceX’s Crew Dragon Resilience spacecraft glided to a smooth automated docking Monday night at the International Space Station, delivering four astronauts to join the three-person crew already on-board, boosting the size of the lab’s long-duration crew to seven for the first time.
