NASA aims to send astronauts to the moon in March after acing the latest rocket fueling test.

NASA announced it is preparing to roll out the Artemis II rocket and Orion spacecraft from the Vehicle Assembly Building to Launch Pad 39B at Kennedy Space Center no earlier than Jan. 17, marking a major milestone toward the first crewed mission of the Artemis program.

NASA announced Thursday that private space company Astrobotic will deliver the agency’s moon rover, VIPER, to the moon’s south pole by end of 2023. Under this initiative, NASA will pay private companies to deliver payloads to the moon to establish a lasting presence on the lunar surface. Prior to landing VIPER on the moon, Astrobotic will land its own lunar lander, Peregrine, as early as next year, under a NASA CLPS contract. The Griffin lunar lander is capable of delivering up to 500 kilograms of mass to the lunar surface, according to a news release. After landing, VIPER will come down from Griffin’s ramp onto the lunar surface and will begin mapping lunar water ice.
