The systems include the Orion crew vehicle, SpaceLaunch System (SLS) launch vehicle, and Exploration Ground Systems (EGS). The first uncrewedlaunch of the SLS and Orion will occur no earlier than (NET) November 2021 and the first crewedlaunch date is NET September 2023. The Orion program will finalize assembling and testing the first crewed vehicle and deliver thesystem to EGS at KSC. The program will start installing, assembling, and testing the second crewedvehicle and continue hardware production for the third. The SLS launch vehicle production and certification for flight will continue at Michoud AssemblyFacility and Marshall Space Flight Center along with engine and core stage testing at Stennis SpaceCenter. Key launch vehicle components will be delivered to EGS at Kennedy Space Center forintegration into the final flight launch vehicle with the Orion crew vehicle. The Budget providesfunding for development of the Block 1B upgrade to the SLS. EGS will continue to prepare launch infrastructure and operations requirements in support of theSLS and Orion programs. Modifications to existing facility and command and control systems willbe ongoing, including continued construction of Mobile Launcher 2 and modifications for theBlock 1B launch vehicle NASA will explore approaches for reducing the costs of future exploration missions to enable amore sustainable and scalable exploration program.Exploration Research and Development (ERD) The overarching goal of ERD is to infuse technologies and research into the development ofhuman exploration capabilities using a combination of unique in-house activities, competedresearch, and public-private partnerships.

enabling human research that will form the basis for future human spaceflight missions. ERD iscomprised of five programs: Human Landing System (HLS), Advanced Cislunar SurfaceCapabilities (ACSC), Gateway, Advanced Exploration Systems (AES), and Human ResearchProgram (HRP). The major initiative in the FY 2022 Budget is the HLS program, which utilizes essentialcommercial partnerships to develop and jointly deploy the integrated landing system that willtransport crew to and from the lunar surface and establish a series of lunar missions that build onthat capability. The Budget provides sufficient funding for the HLS program to maintaincompetition both leading up to and subsequent to the Artemis program’s first crewed Moon landingmission. ACSC leads architecture and mission planning while providing technical direction for HumanExploration and Operations (HEO) missions through the HEO System Engineering and Integrationoffice. The program is also conducting risk reduction studies to develop strategies and identifytechnologies to feed into lunar sustainability and future Mars efforts. Gateway is a platform that will orbit the Moon and support lunar landers and surface activities.Gateway will eventually consist of a Power and Propulsion Element (PPE), the Habitation andLogistics Outpost (HALO), at least one module contributed by NASA’s international partners, and besupported by logistics services. AES will continue work to identify and address knowledge gaps and deliver fundamentalcapabilities to provide astronauts a place to live and work with integrated life support systems,radiation protection, food, fire safety, avionics and software, logistics management, and wastemanagement systems.
