Artemis teams conduct the final simulation for the Artemis I mission inside the Launch Control Center at NASA’s Kennedy Space Center in Florida on Aug. 4, 2022. Artemis I will be the first integrated test of NASA’s Space Launch System (SLS) rocket and Orion spacecraft. During the flight, Orion will launch atop the most powerful rocket in the world and fly farther than any spacecraft for humans has ever flown. The spacecraft will stay in space longer than any human spacecraft has without docking to the International Space Station and return home faster than ever before. Shown here, from left to right, is Bubba Howard and Lisa DeVries, who are in charge of the safety console.

Artemis teams conduct a launch simulation for the Artemis I mission inside Firing Rooms 1 and 2 of the Rocco A. Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida on Oct. 27, 2022. Artemis I will be the first integrated test of NASA’s Space Launch System (SLS) rocket and Orion spacecraft. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by launching Orion atop the SLS rocket, operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown. During the flight, Orion will launch atop the most powerful rocket in the world and fly farther than any human-rated spacecraft has ever flown, paving the way for human deep space exploration and demonstrating our commitment and capability to extend human presence to the Moon and beyond.

Artemis III launch team members participate in a cryogenic propellant loading simulation on Wednesday, June 10, 2026, inside Firing Room 1 and 2 of the Rocco A. Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida. Members of NASA’s Exploration Ground Systems team rehearse the steps to load the super-cooled liquid hydrogen and liquid oxygen into the SLS (Space Launch System) rocket core stage, a process that starts several hours before liftoff for the Artemis III mission. Artemis III will carry out a series of objectives in low Earth orbit designed to demonstrate critical systems needed for future lunar landings, beginning with Artemis IV.

Mike Guzman, main propulsion systems engineer, participates in a wet dress rehearsal for the Artemis II mission on Monday, Feb. 2, 2026, inside Firing Room 1 at the Rocco A. Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida. The wet dress rehearsal allows the Artemis II launch team to run through operations to load propellant, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and drain the tanks to practice timelines and procedures for launch. The Artemis II test flight will take Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA, and Mission Specialist Jeremy Hansen from the CSA (Canadian Space Agency), around the Moon and back to Earth from Launch Complex 39B at NASA Kennedy.

CAPE CANAVERAL, Fla. – A new window is lowered toward the existing Firing Room windows in the Launch Control Center at NASA's Kennedy Space Center in Florida. New, hurricane-rated window systems for the four Firing Rooms and the vestibule areas between Firing Rooms 1 & 2 and Firing Rooms 3 & 4 are being installed. In order to avoid operational impacts the new windows are being installed on the outside of the existing windows, enclosing the space formerly occupied by the louvers. The old windows will remain in place until the new windows are completely installed and leak tested. This approach will continue to keep the firing rooms from being exposed to the elements.
