NASA officials said Tuesday the weekend test-firing of the Space Launch System moon rocket’s core stage was cut short by an out-of-limits parameter in a hydraulic system for gimbaling, or vectoring, one of its engines. NASA Administrator Jim Bridenstine told Spaceflight Now engineers are “feeling pretty good” about the data gathered during the shortened test-firing, and managers may decide to ship the SLS core stage to the Kennedy Space Center for launch preparations without re-attempting the planned eight-minute hot fire.

The third in a new series of Chinese high-resolution mapping satellites lifted off Saturday aboard a Long March 2D rocket, joining two other craft launched into similar orbits in December.

Like reaching back in time to examine the conditions that existed in the ancient solar system, NASA has launched a robotic probe to visit Asteroid Bennu and return an unspoiled sample of the primitive body that may hold the seeds of life.
