Of the six launches known to be scheduled to close out August, there’s only one – Artemis I — that truly matters in any real sense. The others will be duly recorded but little remembered in what could be the busiest launch year in human history.
KENNEDY SPACE CENTER, Fla. (NASA PR) — The Space Launch System (SLS) rocket and Orion spacecraft are slated to return to launch pad 39B at NASA’s Kennedy Space Center in Florida in early June for the next wet dress rehearsal attempt.
KENNEDY SPACE CENTER, Fla. (NASA PR) — Teams at NASA’s Kennedy Space Center in Florida continue to work on the main tasks needed to prepare the Space Launch System (SLS) rocket and Orion spacecraft to return to launch pad 39B for the next wet dress rehearsal attempt.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA is planning to proceed with a modified wet dress rehearsal, primarily focused on tanking the core stage, and minimal propellant operations on the interim cryogenic propulsion stage (ICPS) with the ground systems at Kennedy. Due to the changes in loading procedures required for the modified test, wet dress rehearsal testing is slated to resume with call to stations on Tuesday, April 12 and tanking on Thursday, April 14. Wet dress rehearsal is an opportunity to refine the countdown procedures and validate critical models and software interfaces. The modified test will enable engineers to achieve the test objectives critical to launch success.
Engineers have identified a helium check valve that is not functioning as expected, requiring these changes to ensure safety of the flight hardware. Helium is used for several different operations, including purging the engine, or clearing the lines, prior to loading propellants during tanking, as well as draining propellant. A check valve is a type of valve that allows liquid or gas to flow in a particular direction and prevents backflow. The helium check valve is about three inches long and prevents the helium from flowing back out of the rocket.
Following the modified test, the Space Launch System rocket and Orion spacecraft will return to the Vehicle Assembly Building (VAB) where engineers will evaluate the valve and replace if needed. Teams are confident in the ability to replace the valve once back in the VAB.
NASA will host a teleconference to discuss details on Monday, April 11. Check back at this blog for an update on the countdown timeline prior to the modified wet dress rehearsal testing for the Artemis I mission. NASA is streaming live video of the rocket and spacecraft on the Kennedy Newsroom YouTube channel.
HUNTSVILLE, Ala. (NASA PR) — As teams continue to prepare NASA’s Space Launch System (SLS) rocket for its debut flight with the launch of Artemis I, NASA and its partners across the country have made great progress building the rocket for Artemis II, the first crewed Artemis mission. The team is also manufacturing and testing major parts for Artemis missions III, IV and V.
CAPE CANAVERAL SPACE FORCE BASE, Fla. (NASA PR) — The Interim Cryogenic Propulsion Stage for the second flight of NASA’s Space Launch System (SLS) rocket arrived in Florida on July 28 for the final phase of production. The stage and its single RL10 engine provide the in-space propulsion needed to send NASA’s Orion spacecraft and its crew on a precise trajectory to the Moon for Artemis II, the first crewed mission of NASA’s Artemis lunar missions. It is the first piece of the rocket for the Artemis II flight to arrive in Florida. Boeing and United Launch Alliance, the contractor team for the stage, shipped the Interim Cryogenic Propulsion Stage from ULA’s facilities in Decatur, Alabama, to its Delta IV Operation Center at Cape Canaveral Space Force Station. The stage will undergo final processing and checkout before it is transported to NASA’s Kennedy Space Center for launch preparations.
With Artemis, NASA will land the first woman and the first person of color on the lunar surface and establish long-term exploration at the Moon in preparation for human missions to Mars. SLS and NASA’s Orion spacecraft, along with the commercial human landing system and the Gateway in orbit around the Moon, are NASA’s backbone for deep space exploration. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

NASA to accept delivery of rocket stage to prepare for transport to Kennedy Space Center for integration and launch
STENNIS SPACE CENTER, Mississippi, April 21, 2021 (Boeing PR) — Boeing [NYSE: BA] begins delivery of the Space Launch System (SLS) rocket cryogenic core stage to NASA today in preparation for launch of the Artemis I mission, the first moon mission in nearly 50 years.
EL SEGUNDO, Calif., July 20, 2020 (Aerojet Rocketdyne PR) — Aerojet Rocketdyne recently completed all of its propulsion hardware for the first crewed flight of NASA’s Space Launch System (SLS) rocket and Orion spacecraft.
The engines and motors, which Aerojet Rocketdyne produces at its major space operations sites across the country, will support NASA’s Artemis II mission. The Artemis II mission is the second flight of SLS and Orion and the first to send an astronaut crew to fly around the Moon.
