NASA’s Exploration Ground Systems team, including engineers, technicians and crane operators with contractor Jacobs, are practicing lifting and stacking operations with pathfinder segments of Northrup Grumman’s solid rocket boosters, which will provide extra thrust for NASA’s Space Launch System rocket. Practice took place in High Bay 4 of the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida.
”The pathfinder training has gone extremely well,” according to Michael McClure, Jacobs’ lead engineer for the Handling, Mechanical and Structures Engineering Group. “This is part of a series of practice exercises, which are providing great experience, especially for our new technicians, engineers, quality control personnel and crane operators.”
Stacking rehearsals help prepare the team for actual processing of launch hardware for Artemis missions. These specific pathfinder segments are inert, full-scale replicas of the actual solid rocket boosters, with the same weight (300,000 pounds) and center of gravity.
During launch hardware processing, the booster segments will be shipped by train to Kennedy from the Northrup Grumman facility in Utah. They will arrive at a processing facility to be configured for final processing, then move to the VAB, where the launch processing team will stack them vertically on the mobile launcher. After the boosters are stacked, the SLS Core Stage will be lowered onto the mobile launcher and will be mated to the boosters.
At launch, the five-segment, 17-story-tall twin boosters will provide 3.6 million pounds of thrust each at liftoff to help launch the SLS carrying Orion on Artemis I, its first uncrewed mission beyond the Moon.
The Apollo 11 mission, which landed the first two humans on the Moon, remains one of mankind’s most impressive achievements. To honor that historic event on its 50th anniversary, several activities are taking place at Kennedy Space Center in Florida, including multiple shows on NASA TV and the agency’s website:
Tuesday, July 16: Astronaut Michael Collins, who served on that historic mission in July 1969, will start the day with a visit to the Astronaut Crew Quarters in Kennedy’s Neil Armstrong Operations & Checkout Building before participating in the day’s televised events.
From 9:15 to 10 a.m. EDT, Collins will speak with Kennedy Director Bob Cabana at Pad 39A, the site of the July 16, 1969, launch. Cabana was the commander of STS-88, the first International Space Station assembly mission, which celebrated its 20th anniversary on Dec. 10, 2018.
Friday, July 19: Tune in to a pair of special live broadcasts from Kennedy’s Apollo/Saturn V Center. The first, an Apollo 11 show titled “NASA’s Giant Leaps: Past and Future,” is from 1 to 3 p.m. EDT. It will honor the heroes of Apollo, and examine NASA’s future plans, including the Artemis missions that are part of the agency’s Moon and Mars human space exploration. That will be followed by a program titled “STEM Forward to the Moon” from 3 to 3:30 p.m. EDT, featuring kids across the nation participating in Moon landing simulations and other activities.
Remember to tune in to NASA TV and the agency’s website for the special Apollo 11 coverage.
