NASA's Marshall Space Flight Center: A hub for historic and modern-day rocket power


NASA s George C. Marshall Space Flight Center has more than six decades of history designing, building and testing a storied series of rockets, rocket engines and instruments to fly in space. The center’s accomplishments include the Redstone rocket used to launch Project Mercury, the Saturn rockets for the Apollo program, the Skylab space station, and the Hubble Space Telescope.
Marshall is located on the grounds of the U.S. Army Redstone Arsenal in Huntsville, a city in northern Alabama about 145 miles (233 kilometers) northwest of Atlanta, Georgia. The NASA Center employs nearly 6,000 people, according to its official NASA website. Marshall also manages NASA s Michoud Assembly Facility near New Orleans, where giant rocket stages can be built and loaded onto barges for transportation to launch facilities at Kennedy Space Center in Florida. ....

SLS Core Stage Green Run validates propulsion system performance and modeling


SLS Core Stage Green Run validates propulsion system performance and modeling
May 11, 2021
Engineers with NASA’s Space Launch System (SLS) program and prime Core Stage contractor Boeing continue to review terabytes of data from the now-complete, once-in-a-generation Green Run design verification test campaign. A series of eight test cases were completed, culminating in a 500-second long, full-duration static firing of the stage in the B-2 Test Stand at Stennis.
The Core Stage was the major new piece developed for the agency’s SLS launch vehicle, and both NASA and Boeing are pleased with results seen so far. Initial analysis and reviews of the test-firing data show that actual Main Propulsion System (MPS) performance was close to most predictions by analytical models and the system demonstrated operating margin during stressing tests conducted during the static fire. ....

NASA EGS, Jacobs preparing SLS Core Stage for Artemis 1 stacking


NASA EGS, Jacobs preparing SLS Core Stage for Artemis 1 stacking
May 6, 2021
The Core Stage of NASA’s first Space Launch System (SLS) vehicle arrived at the Kennedy Space Center (KSC) and was moved into the Vehicle Assembly Building (VAB) on April 29. The stage is now in the hands of KSC’s Exploration Ground System (EGS) program and prime test operations and support contractor (TOSC) Jacobs.
The long-awaited milestone allows EGS and Jacobs to work towards putting the whole Orion/SLS vehicle together and beginning months of testing to get it ready for the launch of Artemis 1. The stage is now in the low bay of the VAB, where some “traveled” work from the recently-completed Green Run design verification campaign will be performed in parallel with preparations for stacking with the new launch vehicle’s Solid Rocket Boosters (SRB), which are already in place on the Mobile Launcher in VAB High Bay 3. ....
