NASA Conducting Extensive Testing of Solar Electric Propulsion (SEP) for Lunar Gateway
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
NASA CAPSTONE targeting 13-22 June launch window; KARI Danuri set for 2 Aug, NASA Artemis 1 team working to achieve WDR 19 June then NET Aug launch; Vessels are bound for ~1,609×70,006km NRHO, elliptical 100km polar orbit, and 100×61,155km DRO respectively; NASA PRISM science proposals Lunar-VISE (investigation of Gruithuisen Domes), LEIA (study of yeast exposed to lunar environment) to receive CLPS task orders for launch circa 2026; NASA SSTR awarding US$150K to Air Company Holdings / NYU for development of RP-1 production process using only CO2 / H2; NASA Break the Ice Lunar Challenge phase 2 distributing $3M for water harvesting tech
Selected from 62,719 submissions across South Korea by a 1000-person focus group, Korea Pathfinder Lunar Orbiter, now Danuri (Moon Enjoy), set for launch on 2 Aug (19:37 EDT) to 100-km Moon orbit on SpaceX Falcon 9 via ballistic lunar transfer; 678-kg spacecraft is outfitted with 6 instruments – KARI-built Lunar Terrain Imager, Wide-Angle Polarimetric Camera, Magnetometer, Gamma-Ray Spectrometer, Disruption Tolerant Network Experiment Payload and NASA provided ShadowCam; NASA will also assist Danuri with ground station / comms / navigation support and 9-member KPLO Participating Scientist Program
First commercial orbital mission ‘Inspiration4’ on SpaceX Dragon capsule, sending humans furthest from Earth in 21st century, reaching 585km; Inspiration4 Commander Jared Isaacman reflects on “single most impactful moment” being Moonrise, urges space travelers push “little bit more and get out there [Moon]”; William Shatner, famous for Star Trek Captain Kirk portrayal, insists “everybody in the world needs to do this” after Blue Origin flight; Yusaku Maezawa and assistant Yozo Hirano launching to ISS 8 Dec via Soyuz; Maezawa organizing lunar orbit on Starship with 10-12 member crew NET 2023
