Q&A with Marc Rayman, chief engineer on NASA’s Dawn mission (members only)

After launching Nov. 23 and arriving in lunar orbit over the weekend, China’s Chang’e 5 sample return mission landed on the moon Tuesday, targeting a volcanic region in the Oceanus Procellarum region. On Thursday, the craft’s ascender vehicle took off to begin the trip back to Earth, followed by a successful docking with the mission’s return vehicle in lunar orbit Saturday.

Singed and blackened from three fiery trips to the edge of space and back, a Falcon 9 rocket returned to Cape Canaveral on Sunday after a mission last that week carried the Israeli Beresheet moon lander into orbit, ready for inspections before attempting a fourth — and likely final — launch this spring.

A Falcon 9 rocket lifted off from Vandenberg Air Force Base at 4:39 a.m. PDT (7:39 a.m. EDT; 1139 GMT) Wednesday, and SpaceX successfully landed the rocket’s first stage on a drone ship in the Pacific Ocean. The mission’s primary objective is the deployment of 10 Iridium Next communications satellites into low Earth orbit.
