The Gateway lunar space station configuration and major international and commercial partners.

Josh Litofsky leads a Gateway lunar dust adhesion testing campaign at NASA’s Johnson Space Center in Houston. His team studies how lunar dust interacts with materials chosen for Gateway's construction. Here, Litofsky scoops lunar stimulant into a sample holder. Litofksy’s work seeks to validate the Gateway On-orbit Lunar Dust Modeling and Analysis Program (GOLDMAP), developed by Ronald Lee, also of Johnson Space Center. By considering factors such as the design and configuration of the space station, the materials used, and the unique conditions in lunar orbit, GOLDMAP helps predict how dust may move and settle on Gateway’s external surfaces.

Engineers and technicians at NASA’s Kennedy Space Center in Florida are preparing the Mass Spectrometer observing lunar operations (MSolo) for launch inside the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Sept. 25, 2020. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface. MSolo hardware is a payload for a robotic mission to the Moon as part of the Commercial Lunar Payload Services (CLPS) launching to exploring Lacus Mortis, a large crater on the near side of the Moon in 2021. A future mission will send a mobile robot named the Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon to prospect for water. VIPER will have several instruments that will allow it to detect and sample water including MSolo, the Neutron Spectrometer System, the Near Infrared Volatiles Spectrometer System and The Regolith and Ice Drill for Exploring New Terrain (TRIDENT).

The primary structure of the Gateway space station's HALO (Habitation and Logistics Outpost) module is one step closer to launch following welding completion in Turin, Italy. HALO is one of four Gateway modules where astronauts will live, conduct science, and prepare for lunar surface missions. NASA is partnering with Northrop Grumman and their subcontractor Thales Alenia Space to develop HALO.

NASA Glenn Research Center has received the first of three Advanced Electric Propulsion System (AEPS) thrusters for the Gateway lunar space station. Built by L3Harris Technologies, the thruster will undergo testing before integration with Gateway’s Power and Propulsion Element, launching with the HALO module ahead of Artemis IV.

Instruments for NASA’s Mars Spectrometer observing lunar operations (MSolo) are in view at left in the high bay of the Space Station Processing Facility (SSPF) at NASA's Kennedy Space Center in Florida, on May 16, 2019. The center is celebrating the SSPF’s 25th anniversary. The facility was built to process elements for the International Space Station. Now it is providing support for current and future NASA and commercial provider programs, including Commercial Resupply Services, Artemis 1, sending the first woman and next man to the Moon, and deep space destinations including Mars.

The Lunar Gateway Launch, mapped. Gateway's first elements, the Power and Propulsion Element and HALO (Habitation and Logistics Outpost), will launch together to lunar orbit, where they’ll set the stage for Artemis IV: the first Gateway assembly mission. During this milestone mission, the Artemis IV crew will deliver the European Space Agency's Lunar I-Hab, dock it to HALO, and enter the space station for the very first time. NASA is currently targeting a 2027 launch for HALO and the Power and Propulsion Element. This timeline allows for the roughly year-long journey to lunar orbit and ensures everything is in place ahead of Artemis IV.

KENNEDY SPACE CENTER, FLA. - NASA's Lunar Prospector spacecraft launched successfully on its way to the Moon from Launch Complex 46 (LC46) at Cape Canaveral Air Station on Jan. 6 at 9:38 p.m. EST. It was the inaugural launch of Lockheed Martin's Athena II launch vehicle and the first launch from LC46, operated by Spaceport Florida Authority. Lunar Prospector, built for the NASA Ames Research Center by Lockheed Martin, is a spin-stabilized spacecraft designed to provide NASA with the first global maps of the Moon's surface and its gravitational magnetic fields, as well as look for the possible presence of ice near the lunar poles. It will orbit the Moon at an altitude of approximately 63 miles during a one-year mission.

These photos show teams at NASA’s Michoud Assembly Facility in New Orleans preparing, moving, and loading the engine section of a future SLS (Space Launch System) rocket to NASA’s Pegasus barge Aug. 28. The hardware will form the bottom-most section of the SLS core stage that will power NASA’s Artemis IV mission, which will be the first mission to the Gateway space station in lunar orbit under the Artemis campaign. The barge will transport the spaceflight hardware to NASA’s Kennedy Space Center in Florida via the agency’s Pegasus barge. Once in Florida, the engine section will undergo final outfitting inside Kennedy’s Space Station Processing Facility.

An artist’s rendering displays a configuration of the lunar-orbiting Gateway space station’s modules and visiting spacecraft. The core elements of Gateway consist of the Habitation and Logistics Outpost (HALO) element, the Power and Propulsion Element (PPE), and Lunar I-Hab. Visiting vehicles include the Orion spacecraft, the Logistics Module, and the Human Landing System. Gateway is built in collaboration with NASA’s commercial and international partners to serve as a multiuse space port for lunar science as humanity’s first place to live and work in lunar orbit.

S70-46152 (July 1970) --- Two crew men of the Apollo 14 lunar landing mission participate in lunar surface simulation training at the Kennedy Space Center (KSC). They are deploying components of the Apollo lunar surface experiments package (ALSEP). Standing in the center next to the ALSEP central station is astronaut Alan B. Shepard Jr. (wearing red stripe on space suit), commander. Astronaut Edgar D. Mitchell, lunar module pilot, is in the left foreground. Both crew men are wearing the Extravehicular Mobility Units (EMU).
