The Artemis program is a human spaceflight program by the United States. Missions in the program are aimed at exploration of the Moon, including crewed and robotic exploration of the lunar surface. Three flights of the Orion Multi-Purpose Crew Vehicle are currently planned for launch in the Artemis program in the early 2020s, beginning with Artemis 1. Before Artemis was named, the flights were referred to as "Orion missions". Numerous supporting scientific and technology demonstration missions are planned for launch under the program's Commercial Lunar Payload Services, in addition to planned and proposed uncrewed logistical missions to construct and resupply the Lunar Gateway and its expendable and reusable lunar landers in lunar orbit.
|Mission||Launch date||Crew||Launch vehicle[a]||Launch pad||Duration[b]|
||2021||N/A||SLS Block 1 Crew||Kennedy LC-39B||~25d|
|Maiden flight of the SLS, carrying an uncrewed Orion capsule and thirteen CubeSats selected through several programs. The payloads will be sent on a trans-lunar injection trajectory.|
|Artemis 2||Q4 2022||TBA||SLS Block 1 Crew||Kennedy LC-39B||~10d|
|First crewed flight, carrying four crew members along with numerous CubeSats to be selected through the CubeSat Launch Initiative.|
|Artemis 3||2024||TBA||SLS Block 1 Crew||Kennedy LC-39B||~30d|
|Carrying the Artemis 3 mission hardware, expected to be the first lunar landing of the Artemis program.|
|Artemis 4 (Proposed)||2025||TBA||SLS Block 1B Crew||Kennedy LC-39B||~30d|
|Debut of the SLS Block 1B and the Exploration Upper Stage.|
|Artemis 5 (Proposed)||2026||TBA||SLS Block 1B Crew||Kennedy LC-39B||~30d|
|Artemis 6 (Proposed)||2027||TBA||SLS Block 1B Crew||Kennedy LC-39B||~30d|
|Artemis 7 (Proposed)||2028||TBA||SLS Block 1B Crew||Kennedy LC-39B||>60d|
The Commercial Lunar Payload Services (CLPS) program will support the Artemis program by landing several small payloads focused on scouting for lunar resources, in situ resource utilization (ISRU) experiments and lunar science, in preparation for an extended human presence on the lunar surface.

NASA is seeking proposals from U.S. small satellite developers to fly their CubeSat missions as secondary payloads aboard the SLS on the Artemis 2 mission under the agency's CubeSat Launch Initiative (CSLI).
NASA on Aug. 5 released a solicitation for cubesats to ride along with the first crewed flight of the Space Launch System rocket and Orion capsule, with the caveat that selected projects fill strategic knowledge gaps for future lunar and Mars exploration.
But now NASA is going to fly all three missions — EM-1, EM-2, and Europa Clipper — on Block 1. [...] According to the memo, NASA will aim to have the second platform ready for a Block 1B launch in the beginning of 2024.
