The interim cryogenic propulsion stage (ICPS) completed its approximately 18-minute trans-lunar injection (TLI) burn and the spacecraft has separated from the stage. Orion fired its auxiliary thrusters to move a safe distance away from the expended stage and the spacecraft is on its way to the Moon. NASA will hold a postlaunch news conference at …
The perigee raise maneuver has been successfully completed. The interim cryogenic propulsion stage fired for just over 20 seconds to raise the lowest point of Orion’s Earth orbit in preparation for the critical trans-lunar injection burn that will send Orion to the Moon. The trans-lunar injection burn is currently targeted for about 3:14 a.m. EST …
Orion’s solar arrays have completed their deployment. The arrays are drawing power, and early data suggests good performance. The next milestone will be a perigee raise maneuver targeted for approximately 2:41 a.m. EST to raise Orion’s orbit in preparation for the critical trans-lunar injection that will send Orion to the Moon.
Space Launch System core stage main engine cutoff is complete, and the core stage has separated from the interim cryogenic propulsion stage and Orion spacecraft. The next milestone is deployment of Orion’s solar arrays, scheduled to begin approximately 18 minutes after launch.
The service module fairing and launch abort system have successfully separated from the Orion spacecraft. The SLS core stage will continue to fire until about 8 minutes after launch.
The Space Launch System’s (SLS) solid rocket boosters have successfully jettisoned. The SLS core stage will continue to fire until 8 minutes after launch. In about one minute, the service module fairing and launch abort system will separate from the Orion spacecraft.
NASA’s Space Launch System rocket, carrying the uncrewed Orion spacecraft lifted off from Launch Complex 39B in Florida at 1:47 a.m. EST. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew …
The mission management team has polled “go” to proceed with the terminal count sequence. The launch director is also “go” and teams have set a new target launch time of 1:47 a.m. EST and the countdown clock resumed at 1:37 a.m. With approval from the launch director and managers, a series of countdown milestones for …
Teams have extended their planned 30-minute hold, and mission managers are expected to target a new time for launch. The Eastern Range and launch teams have since resolved an issue that caused a loss of signal from a radar site and are currently in the process of conducting required tests to ensure communication and tracking …
Teams are replenishing liquid hydrogen into the core stage and report seeing good data where a red crew tightened connections in the area of a leaky valve on the mobile launcher. The leak is not reoccurring. Engineers are back into liquid hydrogen fast fill operations on the interim cryogenic propulsion stage. Engineers also are tracking …
