NASA delays critical Artemis 2 rocket fueling test due to below-freezing temperatures, launch no earlier than Feb. 8
NASA Delays Critical Artemis 2 Rocket Fueling Test Due to Unusually Cold Weather
The Artemis 2 mission, a crucial step towards returning humans to the moon, has hit a snag due to the unseasonably cold weather forecasted to hit the Space Coast this weekend. The wet dress rehearsal for the Space Launch System (SLS) rocket, which was expected to begin last night (Jan. 29), has been pushed back by two days.
The Wet Dress Rehearsal: A Critical Test for the SLS Rocket
The wet dress rehearsal is the last major test the SLS rocket has to pass before being cleared to launch a crew of astronauts to the moon. During this test, ground operators will exercise the full scenario of an actual mission countdown, running the clock to just 30 seconds prior to engine ignition, powering on the rocket and fully fueling its two stages with cryogenic fuels. This test is crucial in ensuring that the rocket is ready for the Artemis 2 mission, which will mark the first time in over 50 years that humans have headed towards the moon.
The Impact of Cold Weather on the SLS Rocket
Cold weather and its effect on the SLS rocket and launchpad ground infrastructure are variables that NASA takes very seriously. The same solid rocket booster (SRB) technology and components used during the space shuttle era have been refitted to power the SLS rocket. For context, yesterday's originally scheduled call to stations came just one day after the 40th anniversary of the space shuttle Challenger disaster, which exploded during launch due to the effects of sub-freezing temperatures on hardware aboard the vehicle's SRBs resulting in the tragic loss of the mission's crew.
The Artemis 2 Mission: A Test Flight for the Orion Spacecraft
The Artemis 2 mission will carry a crew of four astronauts, including NASA astronauts Reid Wiseman as mission commander, Victor Glover as mission pilot, and Christina Koch as mission specialist, as well as Canadian Space Agency astronaut Jeremy Hansen as another mission specialist. The crew will travel on the Orion spacecraft, which will be launched on top of the SLS rocket. The mission will last about 10 days and will further qualify the Orion spacecraft for crewed operations and pave the way for Artemis 3, which NASA says will be the first mission in the program to land astronauts on the lunar surface.
The Implications of the Delay
The delay in the wet dress rehearsal and the subsequent launch of the Artemis 2 mission will have significant implications for the Artemis program. The first Artemis 2 launch window extends to Feb. 11, but range availability could cut those opportunities short. NASA is also targeting Feb. 11 for the launch of SpaceX's Crew-11 mission to the International Space Station (ISS). This crew's arrival to the space station will end a short period of reduced occupancy aboard the orbital lab, which has been operating with a skeleton crew of three since the medical evacuation of Crew-11 astronauts ended their mission a month earlier than expected.
Forward-Looking Thoughts
The delay in the Artemis 2 mission is a setback, but it is not a major one. NASA has a robust plan in place to ensure that the mission is successful, and the agency is working hard to minimize the impact of the delay. The Artemis program is a crucial step towards returning humans to the moon and establishing a sustainable presence on the lunar surface. The success of this mission will pave the way for future missions, including Artemis 3, which will be the first mission in the program to land astronauts on the lunar surface.
