CAPE CANAVERAL, Fla. — NASA’s subsequent megarocket for the moon, the Space Launch System (SLS) has arrived in Florida. The behemoth’s core stage arrived at NASA’s Kennedy Area Middle by way of barge final Tuesday night (April 27).
After a decade within the making, the company celebrated because the core stage rolled into the Automobile Meeting Constructing (VAB) two days later (April 29), marking the primary time that all the rocket’s parts had been in the identical place.
Decked out in orange foam insulation, the megarocket will spend the following few weeks within the switch aisle of the VAB earlier than it joins the 2 stable rocket boosters which might be already stacked in Excessive Bay 3.
This summer time, the company’s new Orion crew capsule will likely be mated with the SLS and ready to blast off on an uncrewed take a look at flight across the moon later this yr as a part of the Artemis 1 mission. If all goes as deliberate, company officers stated that the flight might happen as early as November.
On Tuesday afternoon, the Pegasus barge — a vessel that was as soon as used to move exterior tanks for the area shuttle program — sailed into Port Canaveral, floating by the just lately returned SpaceX Crew-2 Falcon 9 booster, on its solution to the dock at Kennedy Space Center.
Floor groups labored to organize the large rocket for offloading, which was scheduled for early Thursday morning (April 29). After a slight delay, the rocket started to emerge from its transporter round 8:30 a.m. EDT (1230 GMT).
4 RS-25 engines, the identical engine that powered the space shuttle, peeked out of the barge, adopted by the brilliant orange core stage. Constructed by Boeing, the core stage stands 212 ft tall (64.6 meters) and 27.6 ft large (8.four m). It holds roughly the 730,000 gallons (2.Eight million liters) of liquid hydrogen and liquid oxygen it takes to energy the big automobile.
Engineers test-fired the 4 RS-25 engines, which had been constructed by Aerojet Rocketdyne, as a part of a scorching hearth take a look at at NASA’s Stennis Space Center in Mississippi, on March 18. The take a look at, which was a repeat of an similar take a look at that ended prematurely again in January, was the ultimate main take a look at of the core stage earlier than delivery to the launch web site. Simulating an actual launch, the engines had been fired up and burned for greater than eight minutes, firmly affixed to a take a look at stand.
After that take a look at was declared successful, the automobile was readied for its journey to Florida. As soon as it is totally assembled, the SLS and its Orion spacecraft will stand roughly 322 ft (98 m) tall. Collectively, its 4 RS-25 engines and twin stable rocket boosters will generate greater than Eight million kilos of thrust.
As soon as NASA assembles the rocket parts, it plans to roll the SLS out of the VAB and to the launch pad for the primary time. As soon as perched atop Pad 39B, the groups will put the rocket via a moist costume rehearsal. Throughout this significant preflight take a look at, the launch group will load the rocket with propellants and follow countdown procedures.
It would then trek again to the VAB and await its launch. That highly-anticipated liftoff is estimated for someday later this yr.
