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 Space Center by way of barge final Tuesday night (April 27).
After a decade in the making, the company celebrated because the core stage rolled into the Vehicle Assembly Building (VAB) two days later (April 29), marking the primary time that the entire rocket’s elements have been in the identical place.
Decked out in orange foam insulation, the megarocket will spend the following few weeks in the switch aisle of the VAB earlier than it joins the 2 stable rocket boosters which are already stacked in High Bay 3.

This summer season, the company’s new Orion crew capsule can 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 may 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 house shuttle program — sailed into Port Canaveral, floating by the not too long ago returned SpaceX Crew-2 Falcon 9 booster, on its approach to the dock at Kennedy Space Center.
Ground groups labored to arrange the huge 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).
Four RS-25 engines, the identical engine that powered the house shuttle, peeked out of the barge, adopted by the intense orange core stage. Built by Boeing, the core stage stands 212 toes tall (64.6 meters) and 27.6 toes broad (8.4 m). It holds roughly the 730,000 gallons (2.8 million liters) of liquid hydrogen and liquid oxygen it takes to energy the large automobile.
Engineers test-fired the 4 RS-25 engines, which have 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 equivalent 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 have 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. Once it is totally assembled, the SLS and its Orion spacecraft will stand roughly 322 toes (98 m) tall. Together, its 4 RS-25 engines and twin stable rocket boosters will generate greater than 8 million kilos of thrust.
Once NASA assembles the rocket elements, it plans to roll the SLS out of the VAB and to the launch pad for the primary time. Once perched atop Pad 39B, the groups will put the rocket by way of a moist gown rehearsal. During this important preflight take a look at, the launch workforce will load the rocket with propellants and observe countdown procedures.

It will then trek again to the VAB and await its launch. That highly-anticipated liftoff is estimated for someday later this yr.
