NASA will make a second attempt to launch the agency's giant Space Launch System rocket Saturday on a test flight to send an unpiloted Orion crew capsule around the moon and back, a major milestone in the agency's ambitious Artemis program.
by trouble cooling one of the rocket's four shuttle-era engines to the required pre-start temperature, managers said Tuesday engineers have come up with a work-around. Assuming final clearance to proceed, the launch team will start a fresh countdown at 4:07 p.m. EDT Thursday.on the Artemis 1 mission at 2:17 p.m. Saturday, one day later than NASA's original backup launch date.
"And we also agreed to move our launch date to Saturday. We are going to reconvene the Mission Management Team on Thursday to review our flight rationale and our overall readiness."ever built by NASA, generating 8.8 million pounds of thrust at liftoff using four Aerojet Rocketdyne RS-25 engines left over from the shuttle program and two Northrop Grumman solid rocket boosters attached to a Boeing-built core stage.
That means the Artemis 1 mission must get off the ground by Monday or the rocket will be hauled back to the VAB, delaying another launch attempt until late September at the earliest or, more likely, to October. Two more fueling attempts failed on April 4 and 14 due to a variety of unrelated problems. Engineers were finally able to fully load the core stage on June 20, but only after a leaking quick-disconnect fitting was isolated that prevented the flow of hydrogen coolant to the core stage engines — a requirement for an actual launch.
John Honeycutt, manager of the SLS program at the Marshall Spaceflight Center, said engineers suspect a faulty sensor might be responsible for the readings from engine 3. Pressure measurements and other data indicate good cooling.
