Barges are docked at the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi, during preparations for a wet dress rehearsal exercise with the core stage of NASA’s Space Launch System rocket. During the wet dress rehearsal, operators will fully load the core stage’s propellant tanks for the first time and countdown just shy of engine ignition. The wet dress rehearsal is the seventh in a series of eight Green Run tests of the core stage’s integrated systems prior to its transport to Kennedy Space Center and launch on the Artemis I mission.

Members of the Artemis I launch team participate in a wet dress rehearsal for the Artemis I mission on April 14, 2022, inside the Launch Control Center at NASA’s Kennedy Space Center in Florida. The wet dress rehearsal is the final major test before launch and allows the team to run through all countdown operations prior to liftoff. The first in an increasingly complex series of missions, Artemis I will test NASA’s Space Launch System rocket and Orion spacecraft as an integrated system prior to crewed flights to the Moon.

Operators at the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi, conducted a wet dress rehearsal for the hot fire test of the core stage of NASA’s Space Launch System on Dec. 21, 2020. In this image, liquid oxygen can be seen venting near the top of the installed core stage. Following the wet dress rehearsal, operators will conduct a full hot fire test of the core stage and its four RS-25 engines. The hot fire will conclude a series of eight Green Run tests of all core stage systems before it is transported to Kennedy Space Center for launch on the Artemis I mission.

NASA test pilot Nils Larson walks around an F-15B research aircraft for a rehearsal flight supporting the agency’s Quesst mission at NASA’s Armstrong Flight Research Center in Edwards, California. The flight was part of a full-scale dress rehearsal for Phase 2 of the mission, which will eventually measure quiet sonic thumps generated by the X-59. The flight series helped NASA teams refine procedures and practice data collection ahead of future X-59 flights.

In the Mission Director's Center at Vandenberg Air Force Base in California, NASA and contractor managers and engineers monitor progress during a countdown rehearsal for the launch of a United Launch Alliance Delta II rocket with the Joint Polar Satellite System-1, or JPSS-1, spacecraft. Built by Ball Aerospace and Technologies Corp. of Boulder, Colorado, JPSS is the first in a series four next-generation environmental satellites in a collaborative program between the NOAA and NASA. Liftoff is scheduled to take place from Vandenberg's Space Launch Complex 2.
