Space Habitat, Biome and Transport System Envisioned by Japan Academic / Industry Partnership
Kyoto University Human Spaceology Center teaming with Kajima Corporation to realize sustainable human occupancy of Moon, Mars, and interplanetary space; Comprehensive 3-part proposal includes 396-m Luna Glass, generating 1g artificial gravity via 20-second rotations, Nature biome extracted from global ecosystem, harnessing “natural capital”, and interplanetary Hexatrack transit which would ferry people to / from LEO station, cislunar Gateway, Mars moon Phobos and have modular capsule design for surface transport, hybrid electromagnetic railgun / chemical propulsion; Researchers estimate a precursor system could be constructed within 50 years, full build-out NET 22nd Century
Power and Propulsion Element of Lunar Gateway under development by Maxar to utilize 6 and 12kW Hall-effect ion thruster systems built by Busek and Aerojet Rocketdyne with Moog xenon propellant feeder and Maxar power processing unit; Current testing regimen comes after initial testing phase finds both systems ‘capable of performing across the full mission power range’; SEP to keep Gateway on efficient NRHO during 15-year mission after Q4 2024 launch via SpaceX Falcon Heavy; Tiangong space station is only human-rated ion-powered spacecraft
Extending 
3 Additional European Service Modules (ESM) Ordered From Airbus Of Germany (With Assistance From 10 European Countries) At Cost Of US$783M; Providing Artemis 4-6 Lunar Astronauts With: Propulsion Via 26.6kN Thrust Orbital Maneuvering System Engine (Orion Main Engine Debuting On ESM-6); Power Via 4 Solar Arrays Measuring 2m x 7m, Housing (3) 2mx2m PV Panels Each, Generating 11.2 kW; Life Support Sufficient To Maintain A 4-Member Crew For Up To 3 Weeks; Orion-1 Awaits Successful SLS Core Stage Hot Fire Test Week Of 21 Feb At Stennis, After Which Integration May Commence At KSC
