NASA studying cause of early end to NASA moon rocket test-firing

January 17, 2021

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.

NASA sets mid-January target for SLS hot fire test

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.

NASA lays out $28 billion plan to return astronauts to the moon in 2024

September 21, 2020

NASA officials released a nearly five-year, $28 billion plan Monday to return astronauts to the surface of the moon before the end of 2024, but the agency’s administrator said the “aggressive” timeline set by the Trump administration last year hinges on Congress approving $3.2 billion in the next few months to kick-start development of new human-rated lunar landers.
