The final, crucial prelaunch test of NASA's Artemis I mission to the moon was halted Sunday due to issues that prevented the safe loading of propellants into the mega rocket.
The agency's next opportunity to begin fueling the 322-foot-tall Artemis I rocket stack, including NASA's Space Launch System and Orion spacecraft, is on Monday. Teams are meeting to assess whether resuming the test tomorrow is possible, and NASA will provide another update today at 5:30 p.m. The test, known as the wet dress rehearsal, began on Friday afternoon at 5 p.m. ET. The wet dress rehearsal simulates every stage of launch without the rocket actually leaving the launchpad.
