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.
