The U.S. Space Force has decided to delay the planned late February launch of two military satellites aboard a ULA Atlas 5 rocket to “evaluate readiness” of one of the payloads, giving officials a window to move forward the liftoff of an unpiloted test flight of Boeing’s Starliner crew capsule to no earlier than March 25.
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.
Boeing said Monday it has re-qualified software for the company’s Starliner crew capsule after programming errors cut short the spacecraft’s first orbital test flight in 2019, and technicians at the Kennedy Space Center have connected the crew and service modules for the next unpiloted Starliner test flight to the International Space Station in March.
A critical test-firing of NASA’s Space Launch System moon rocket in Mississippi ended just 67 seconds after it began Saturday, well short of a planned eight-minute burn that was supposed to clear the way for the space agency to finally ship the rocket’s core stage to the Kennedy Space Center in Florida for launch preparations.
A critical test-firing of the Space Launch System’s core stage engines cut off about a minute into a planned eight-minute burn Saturday on a test stand at NASA’s Stennis Space Center in Mississippi. The rocket’s four engines ignited at 5:27 p.m. EST (2227 GMT) for a test that was to pave the way for the core stage’s shipment to the Kennedy Space Center for launch preparations.
