16 and 19, also with middle-of-the night launch windows. NASA has scheduled backup launch opportunities Nov. EST (0507 GMT) and extends for 69 minutes. Trajectory limitations and the position of the moon relative to Earth determine when the mission can launch. 14. Unlike the mission’s previous countdowns, the next three Artemis 1 launch opportunities will be at night. 21 without any significant leaks, paving the way for launch opportunities in late September and early October.īut the threat from Hurricane Ian forced NASA officials to move the rocket back to the Vehicle Assembly Building for safety, delaying the next Artemis 1 launch attempt to Nov. NASA replaced seals in the connection fully fueled the rocket in a tanking test Sept. 3 was scrubbed by a hydrogen leak in the connection between the core stage of the rocket and its mobile launch platform. Engineers later determined that the thermal measurements were from a bad sensor, and not indicative of a more serious problem.Ī second launch attempt Sept. 29, when data indicated one of the rocket’s four hydrogen-fueled main engines was not being properly thermally conditioned during the countdown. NASA scrubbed the first launch attempt for the Artemis 1 moon mission Aug. NASA is preparing the first $4.1 billion SLS moon rocket for the Artemis 1 test flight, a demo mission to send an unpiloted Orion crew capsule around the moon and back to Earth on a shakedown cruise before it flies with people. The huge rocket is the largest ever built by NASA, and is the centerpiece of the agency’s Artemis moon program, which aims to return astronauts to the lunar surface later this decade. NASA declared the mobile launch platform “hard down” on the launch pad at 10:07 a.m. The 21.4 million pound stack - comprising the rocket, its launch platform, and the crawler - covered the 4.2-mile (6.8-kilometer) distance from the VAB to pad 39B in about 11 hours.Īfter rolling up the ramp to the seaside launch complex, the crawler positioned itself directly over the flame trench and lowered the SLS mobile launch platform onto pedestals. NASA’s diesel powered crawler transporter began moving the rocket out of the VAB at 11:17 p.m.
27 when NASA rolled the rocket back to the hangar to take shelter from Hurricane Ian. The 322-foot-tall (98-meter) SLS moon rocket rode on its mobile launch platform from the Vehicle Assembly Building to Launch Complex 39B at Kennedy Space Center, moving to the pad for the first time since Sept. 14 to start a crucial, long-delayed test flight that officials hope will set the stage for future lunar missions with astronauts. NASA’s Space Launch System moon rocket arrived back on its Florida launch pad Friday, ready for a series of overnight launch opportunities beginning Nov. NASA’s Space Launch System moon rocket emerges from the Vehicle Assembly Building late Nov.
