SpaceX’s Crew Dragon spacecraft will likely return to Earth in August to wrap up a test flight to the International Space Station with NASA astronauts Doug Hurley and Bob Behnken, a senior space agency official said Tuesday.

NASA’s Juno spacecraft barreled toward a Fourth of July rendezvous with Jupiter after a 1.7-billion-mile, five-year trip from planet Earth. The research probe’s main engine ignited for 35 minutes to maneuver Juno into orbit, and engineers received confirmation of the burn’s conclusion on time at 11:53 p.m. EDT Monday (0353 GMT Tuesday).

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.
