NASA’s Artemis moon program is facing delays, but testing on its hardware is still progressing. Engineers at NASA successfully fired up an engine for the Space Launch System (SLS) megarocket, a version that will be used to launch astronauts towards the moon by 2025. The test, which took place at NASA’s Stennis Space Center in Mississippi, lasted nearly as long as a typical launch, approximately 8.5 minutes. The focus of the test was on certifying engines for future Artemis missions that will carry larger payloads and target more ambitious moon missions.
The RS-25 engine type, which has a heritage dating back to the space shuttle program, is under scrutiny. NASA is working to certify these engines for the Artemis missions scheduled for the late 2020s or later. The recent test examined several new engine components, including a nozzle, hydraulic actuators, flex ducts, and turbopumps. By conducting these tests, NASA aims to ensure that the engines are ready for the planned Artemis 5 mission.
The Artemis program, led by NASA in collaboration with over 30 nations, aims to return astronauts to the moon. The program involves partnerships with countries that are either assisting with hardware or sharing the spirit of peaceful space exploration. Initially, Artemis aimed to put an astronaut on the moon by 2024. However, technical and budgetary challenges have caused delays. Recently, NASA announced that the Artemis 2 mission, which will orbit the moon, will now take place in 2025 instead of 2024. Additionally, Artemis 3, which involves a lunar touchdown, has been rescheduled for 2026 instead of the previously targeted 2025.
During a briefing announcing the delay, NASA Administrator Bill Nelson emphasized that safety is their top priority. He stated that the adjustments in the schedule are necessary to allow more time for teams to address challenges related to first-time developments, operations, and integration. Nelson revealed that Artemis 2 is now targeted for September 2025, while Artemis 3 is planned for September 2026. These missions will mark significant milestones as humans will be sent to the lunar south pole for the first time.
Despite the delays in the Artemis moon program, NASA remains committed to pushing forward with testing and development. The recent successful engine test demonstrates the agency’s determination to overcome challenges and ensure the readiness of its hardware. As NASA continues to work towards its goal of returning astronauts to the moon, the Artemis program serves as a symbol of international collaboration and the pursuit of scientific exploration beyond Earth’s boundaries.
