Progress Continues Toward Artemis I Launch (News Release - July 15)
Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, technicians continue to prepare the Space Launch System rocket and Orion spacecraft for Artemis I.
During work to repair the source of a hydrogen leak, engineers identified a loose fitting on the inside wall of the rocket’s engine section, where the quick disconnect for the liquid hydrogen umbilical attaches. The component, called a “collet,” is a fist-sized ring that guides the quick disconnect during assembly operations. Teams will repair the collet by entering the engine section in parallel with other planned work for launch preparations. Technicians have replaced the seals on the quick disconnect of the tail service mast umbilical and will reattach the umbilical plate once the loose collet is addressed.
NASA continues to target the late August launch period and will identify a specific target launch date after engineers have examined the collet.
Technicians continue work associated with battery activations, and plan to turn on the core stage batteries this weekend, before they are installed on the rocket. Next up, teams will start the flight termination systems operations, which include removing the core stage and booster safe and arm devices for calibration and removing and replacing the command receiver decoders with the flight units. The safe and arm devices are a manual mechanism that put the flight termination system in either a “safe” or “arm” configuration while the command receiver decoders receive and decode the command on the rocket if the system is activated.
Meanwhile on the Orion spacecraft, teams installed a technology demonstration that will test digital assistance and video collaboration in deep space. Engineers are also conducting powered testing on the crew module and European service module heaters and sensors.
