Booster stacking continues! The second to last set of segments for NASA’s Space Launch System (SLS) solid rocket boosters were placed on the mobile launcher inside the Vehicle Assembly Building at NASA’s Kennedy Space Center. Engineers with Exploration Ground Systems and Jacobs transported the segments from the Rotation, Processing and Surge Facility, where they have …

The third of five sets of solid rocket boosters for NASA’s Space Launch System (SLS) rocket were placed on the mobile launcher inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. The middle segments, painted with the iconic “worm” logo, were lifted onto the launcher by Jacobs and Exploration Ground Systems …

NASA plans to conduct a second Green Run hot fire test as early as the fourth week in February with the Space Launch System (SLS) rocket’s core stage that will launch the Artemis I mission to the Moon. The Green Run is a comprehensive assessment of the rocket’s core stage prior to launching Artemis missions. …

Booster stacking for NASA’s Space Launch System (SLS) rocket is continuing at NASA’s Kennedy Space Center. The second of five segments for the SLS rocket boosters have been placed on the mobile launcher in preparation for the launch of Artemis I later this year. This marks four out of 10 solid rocket booster segments being …

For the Green Run hot fire test on Jan. 16, NASA set out to acquire test data to support 23 detailed verification objectives. To satisfy the objectives, hot fire test data is used in combination with analysis and testing that has already been completed. These detailed verification objectives are used to certify the design of …

The Space Launch System (SLS) rocket Green Run team has reviewed extensive data and completed preliminary inspections that show the rocket’s hardware is in excellent condition after the Green Run test that ignited all the engines at 5:27 p.m. EST at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. After analyzing initial data, the …

Teams from NASA’s Space Launch System (SLS) Program conducted a hot fire of the Artemis I core stage on Jan. 16 at NASA’s Stennis Space Center. All four RS-25 engines ignited successfully, but the test was stopped early after about a minute. At this point, the test was fully automated. During the firing, the onboard …

The hot fire is underway for the Space Launch System (SLS) rocket core stage at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Engine ignition began at approximately six tenths of a second before T-0, beginning with Engine 1, then Engines 3, 4, and 2 ignited in sequence a few hundredths of a second apart. The test is expected to last about 8 minutes and will include three different power …

The test conductor polled the team and has approved the decision to proceed with the terminal countdown that includes the final 10 minutes before the hot fire. During the terminal countdown, the team is executing the autonomous launch sequence that simulates the countdown for the Artemis I launch. The test transitions from ground control to on-board software control of the core stage and so the test is fully automated starting at T-30 seconds.  Key milestones during the …

The teams are now targeting a hot fire test for NASA’s Space Launch System (SLS) rocket core stage within an hour. The team has completed a successful pressurization demonstration and is evaluating the data to ensure they are ready to proceed. Live coverage is underway on NASA Television and the agency’s website. Teams began the …
