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

Project Artemis (April 2026)
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 (2026)
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

Russian Orbital Station (ROS)
The Russian Orbital Station (ROS) is a planned future space station intended to succeed the Russian Orbital Segment of the ISS. As of December 2025, it is expected to begin construction at the ISS itself by 2028, and is expected to separate from the station by the early 2030s
Serves as a replacement to the 2023 version of the same name, as the assembly sequence has been revised and fully revealed by Roscosmos as of March 2026. Requires the International Space Station add-on for full functionality.
