Crucial first fueling test on tap for SLS core stage later this month
If all goes according to plan, engineers in southern Mississippi later this month will load cryogenic propellants into the core stage of a rocket NASA says will launch astronauts back to the moon, exposing its tankage and internal plumbing to extreme operating conditions hundreds of degrees below zero for the first time. The fueling test — a major milestone in its own right — is a precursor to a high-stakes eight-minute test-firing of the Space Launch System’s four shuttle-era main engines planned as soon as November.

Live coverage: HTV cargo freighter arrives at space station
Five days after launching from Japan, an HTV supply ship arrived Monday at the International Space Station. Capture of the HTV with the station’s robotic arm occurred at 8:13 a.m. EDT (1213 GMT). It’s the last cargo mission to the space station before the arrival of two NASA astronauts on the first crewed U.S. flight to the orbiting research facility since 2011.
