NASA is contemplating a second firing of its moon rocket engines after a important check got here up quick over the weekend, a transfer that would bump the primary flight within the Artemis lunar-landing program into subsequent 12 months. The house company had aimed to launch its new Area Launch System, or SLS, rocket and an empty Orion capsule by the tip of this 12 months, with the capsule flying to the moon and again as a prelude to crew missions. However that date could possibly be in jeopardy following Saturday’s aborted check.
“We’ve a shot at flying it this 12 months, however we have to get by way of this subsequent step,” mentioned Kathy Lueders, head of NASA’s human spaceflight workplace.
All 4 engines fired for barely a minute, reasonably than the supposed eight minutes, on the check stand at NASA’s Stennis Area Middle in Mississippi. The countdown rehearsal for the 65-meter core stage — made by Boeing — included the liquid hydrogen and oxygen tanks, in addition to the all essential computer systems and electronics.
On Tuesday, NASA attributed the automated shutdown to the strict check limits meant to guard the core stage so it may be used on the primary Artemis flight. The hydraulic system for one engine exceeded security parameters, officers mentioned, and flight computer systems shut all the pieces down 67 seconds into the ignition.
NASA mentioned it could alter the check limits if a second check is deemed essential, to forestall one other untimely shutdown. Engineers will proceed to research the information, as managers debate the professionals and cons of continuing with a second check firing at Stennis or delivery the rocket straight to Florida’s Kennedy Area Middle for launch preparations. A few of that Kennedy work may have the ability to be streamlined, Lueders mentioned.
This core stage will be loaded with super-cold gasoline not more than 9 occasions, NASA Administrator Jim Bridenstine informed reporters Tuesday night. A second full-blown check firing would cut back the remaining variety of fill-ups.
The Artemis program is working to place astronauts again on the moon by 2024, a deadline set by the Trump administration. It’s unsure how the incoming White Home will method that timeline.
In its annual report Tuesday, the Aerospace Security Advisory Panel urged NASA to develop a sensible schedule for its Artemis moon program and referred to as into query the 2024 date for returning astronauts to the lunar floor.
On the eve of his departure from NASA, Bridenstine, a former Republican congressman from Oklahoma, burdened that key applications like Artemis have to embody a number of administrations, a long time and even generations. It’s essential, he mentioned, that “we’ve bought buy-in and assist from all of America and members of Congress on either side of the aisle.”
