The rocket will now roll out of its Florida hangar no earlier than mid-February.

"Construction of Starship orbital launch pad at the Cape has begun."

"Replacing an engine, we're probably talking about multiple weeks."

The agency wants the rocket to become a "sustainable and affordable system."

"The agency continues to monitor the rise of COVID cases in the Kennedy area."

"I was really expecting to see a slowdown in the number of new launch vehicles."

"The mission for which is to be determined by the NASA Administrator."

NASA has posted a 360-degree video of its awesome SLS rocket that could be on its way to the moon by the end of this year.

Artemis I Core Stage Arrival at KSC Following a number of impressive engine tests, the various components of the first full spacecraft have all arrived at NASA's Kennedy Space Center, including the newly arrived core stage. That part of the mega-rocked floated up to the spaceport on a 310-foot barge earlier this week.  The post NASA’s Gigantic SLS Rocket Arrives in Florida on Equally Gigantic Barge appeared first on ExtremeTech.

As a veteran of four flights on NASA’s space shuttle, I can tell you that human spaceflight is a hard, complex endeavor. And when astronauts’ lives are at stake you must get it right the first time. That’s why I was impressed with NASA’s successful test firing of its Space Launch System (SLS) core stage on March 18. This rocket paves the way for an exciting era of U.S.-led space exploration, leading to a permanent human presence on the moon and eventual journeys to Mars and beyond. The 499.6 second, full-throttle engine run, which put the core stage through a simulated launch profile, gives America a rocket specifically designed to take astronauts to the moon. That’s an indispensable capability that’s been missing from NASA’s exploration toolbox since Apollo’s Saturn V made its final flight nearly five decades ago.

The core stage for the first flight of NASA’s Space Launch System rocket is seen in the B-2 Test Stand during a second hot fire test, Thursday, March 18, 2021, at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The four RS-25 engines fired for the full-duration of 8 minutes during the test and generated 1.6 million pounds of thrust. The hot fire test is the final stage of the Green Run test series, a comprehensive assessment of the Space Launch System’s core stage prior to launching the Artemis I mission to the Moon.

Photo by NASA/Robert Markowitz via Getty Images NASA will make another attempt next month to test-fire its massive Space Launch System rocket after its first try was cut short, the agency said Friday night. The rocket’s 212-foot-tall core stage will try to fire its four engines for eight minutes at NASA’s Stennis Space Center in Mississippi. The attempt is the last milestone “Green Run” test before the behemoth rocket gets shipped to Florida for its debut launch toward the moon. All four of the rocket’s Aerojet Rocketdyne RS-25 engines ignited together for the first time earlier this month. But what was intended to be an eight minute test only lasted a little over a minute — a much shorter runtime than what engineers needed to proceed to Florida. The SLS core has been in development...

Last weekend, the final and most important test for the Space Launch System rocket that will support the Artemis program took place. It was supposed to be an eight-minute firing of all four RS-25 engines of the core stage, but the entire test lasted for just a little over a minute, after the engines shut off on their own. The reasons behind the early abort, if we can call it that, are still under investigation, but NASA says it had enough...

NASA has now analyzed the test and says there's no physical problem with the rocket. It may even re-run the test, which is one of the final pieces of the puzzle before NASA begins assembling the first flight-ready SLS stack.  The post NASA Still Undecided on New SLS Rocket Test After Early Shutdown appeared first on ExtremeTech.

During a private briefing Tuesday morning, industry officials said their expectations for successfully completing all the test objectives had been only “50/50.”

'If this scenario occurred during a flight, the rocket would have continued to fly' After the weekend's shorter-than-hoped-for test firing of the core stage of NASA's monstrous Space Launch System (SLS) rocket, engineers have confirmed the hardware remains in "excellent condition" and blamed "test parameters that were intentionally conservative."…

NASA powered up the core stage of its new Space Launch System on Saturday (Dec. 5), kicking off the penultimate "green run" test of its next-generation megarocket, according to agency officials. For this "wet dress" rehearsal exercise, engineers at NASA's Stennis Space Center in Mississippi planned to load up the Space Launch System (SLS) rocket's core stage with propellant for the first time, a process that began Monday (Dec. 7) and was expected to last about 48 hours, NASA officials wrote in a blog post. That fueling process began on schedule, but NASA engineers paused shortly after it began to allow time for more analysis.

NASA has laid the groundwork for an order of up to six additional SLS solid core booster rockets, from supplier Northrop Grumman, the agency announced this week. The six additional boosters would join the existing three that NASA previously locked in for use on Artemis 1, Artemis 2 and Artemis 3, which includes the targeted 2024 mission that will bring the next American man and the first American woman to the lunar surface. While this is essentially a long-lead declaration of intent to help partner Northrop Grumman ensure its supply pipeline can supply the additional boosters in a timeline needed by NASA, rather than an actual order for the boosters themselves, it's still a big step with a potential total contract value of $49.5 million, with initial
