NASA’s Space Launch System (SLS) rocket, with the Orion spacecraft atop, slowly makes its way along the crawlerway at the agency’s Kennedy Space Center in Florida on Nov. 4, 2022. Carried by the crawler-transporter 2, NASA’s Moon rocket is venturing the 4.2 miles from the Vehicle Assembly Building to Launch Pad 39B for the Artemis I launch, scheduled for Monday, Nov. 14. Artemis I will be the first integrated test of NASA’s SLS rocket and Orion spacecraft. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by launching Orion atop the SLS rocket, operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown. During the flight, Orion will launch atop the most powerful rocket in the world and fly farther than any human-rated spacecraft has ever flown, paving the way for human deep space exploration and demonstrating our commitment and capability to extend human presence to the Moon and beyond.
Engineers watch as several Praxair trucks carrying their loads of liquid oxygen, or LO2, arrive at Launch Pad 39B at NASA's Kennedy Space Center in Florida. The trucks will offload the LO2 one at a time into the giant storage sphere located at the northwest corner of the pad. The sphere will gradually be chilled down from normal temperature to about negative 298 degrees Fahrenheit, during the first major integrated operation to prepare for the launch of the agency's Orion spacecraft atop the Space Launch System (SLS) rocket. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to pad B to support the launch of the SLS and Orion spacecraft for Exploration Mission-1, deep space missions and NASA’s journey to Mars.
At Launch Pad 39B at NASA's Kennedy Space Center in Florida, construction workers position large segments of the support hardware for a new flame deflector in the flame trench. The new flame deflector will be positioned about six feet south of the shuttle-era flame deflector’s position. During liftoff of NASA’s Space Launch System, the rocket’s flame and energy will be diverted to the north side of the flame trench. The north side of the deflector will be protected by a NASA standard coating. The south side of the deflector will not be slanted and will have no lining. The new design will provide easier access for inspection, maintenance and repair. The Ground Systems Development and Operations (GSDO) Program at Kennedy is managing the installation of the flame deflector for Exploration Mission 1, deep space missions, and NASA's Journey to Mars.
