I've updated the Lunar Gateway add-on on its original link HERE, highlighting its status as cancelled since March 2026 following a major revamp of the entire Artemis program in March 24, 2026. A proper update of Orion will be uploaded shortly, just in time for the launch of Artemis II a few hours from now as of this writing

Artemis 2 during its closest approach to the Moon, 2026-Apr-6

The Artemis Program is a NASA-led multinational lunar exploration program that will reestablish human presence on the Moon since Apollo 17 in 1972. It was formally established in 2017 as a replacement/successor to the Space Shuttle and Constellation programs, aiming to make the first two crewed landings on the Moon in the 21st century by 2028.

NOTES:
- This add-on serves as a replacement to its 2023 and 2025 versions after a major revision of the program was announced by NASA in March 24, 2026. The latter link now only hosts the cancelled Lunar Gateway and SpaceX Dragon-XL spacecraft
- Added Artemis 2, with XYZV trajectory data retrieved from JPL-HORIZONS
- Artemis 3 is now an Earth-orbiting mission reminiscent of Apollo 9
- New, darker paint scheme for the EFT-1 capsule, now reflecting its real-life counterpart
- New CMOD model of Orion retrieved from NASA's Eyes of the Solar System. Three configurations available: EFT-1, Artemis 1-2, and Artemis 3-X
- ICPS stage is now a separate, independent model from EFT-1, to simulate spent DCSS and ICPS stages in both Earth and heliocentric orbit
- Temporarily removed all missions from Artemis 4 and beyond due to lack of data, will be reinstated in the near-future
- Starship HLS and Blue Moon MK2 will be released as separate add-ons

Haven-1 is a planned future space station designed and owned by an aerospace company called Vast Space. Scheduled for launch sometime around 2027, it will become the first commercially-owned space station in LEO, and one of the smallest ever in history. Astronauts are expected to arrive via Crew Dragon spacecraft on 10 to 30-day long missions starting with Vast-1

This serves as a replacment/update to the 2023 version of the same name. Now included a 3D model visualizing the interior cabin of this space station. Visible in Celestia from 2027 to 2030 only
