The Vision for Space Exploration (VSE) was a plan for space exploration announced on January 14, 2004 by President George W. Bush. It was conceived as a response to the Space Shuttle Columbia disaster, the state of human spaceflight at NASA, and as a way to regain public enthusiasm for space exploration.
The Lunar Crater Observation and Sensing Satellite (LCROSS) was a robotic spacecraft operated by NASA. The mission was conceived as a low-cost means of determining the nature of hydrogen detected at the polar regions of the Moon. Launched immediately after discovery of lunar water by Chandrayaan-1, the main LCROSS mission objective was to further explore the presence of water in the form of ice in a permanently shadowed crater near a lunar polar region. It was successful in confirming water in the southern lunar crater Cabeus.
A moonbase is a human outpost on or below the surface of the Moon. More than a mere site of activity or temporary camp, moonbases are extraterrestrial bases, supporting robotic or human activity, by providing surface infrastructure. Missions to the Moon have realized single-mission bases,, as well as some small permanent infrastructure like lunar laser ranging installations.
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research. Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program, and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program.
t/Space was an American aerospace company which participated in NASA's Commercial Orbital Transportation Services (COTS), and later, Commercial Crew Development (CCDev) programs for delivering cargo and crew to the International Space Station. The company was headquartered in Reston, Virginia.
A space tug is a type of spacecraft used to transfer spaceborne cargo from one orbit to another orbit with different energy characteristics. The term can include expendable upper stages or spacecraft that are not necessarily a part of their launch vehicle. However, it can also refer to a spacecraft that transports payload already in space to another location in outer space, such as in the Space Transportation System concept. An example would be moving a spacecraft from a low Earth orbit (LEO) to a higher-energy orbit like a geostationary transfer orbit, a lunar transfer, or an escape trajectory.
The Golden Spike Company was an American space transport startup active from 2010 to 2013. The company was chartered for business in Colorado with the objective to offer private commercial space transportation services to the surface of the Moon. The name of the company is in reference to the ceremonial final spike placed in the First transcontinental railroad upon its completion. The company's Internet site was taken offline in September 2015.
The DARPA XS-1 was an experimental spaceplane/booster with the planned capability to deliver small satellites into orbit for the U.S. Military. It was reported to be designed to be reusable as frequently as once a day, with a stated goal of doing so for 10 days straight. The XS-1 was intended to directly replace the first stage of a multistage rocket by taking off vertically and flying to hypersonic speed and high suborbital altitude, enabling one or more expendable upper stages to separate and deploy a payload into low Earth orbit. The XS-1 would then return to Earth, where it could ostensibly be serviced fast enough to repeat the process at least once every 24 hours.
Firefly Aerospace is an American private aerospace firm based in Cedar Park, Texas, that develops small and medium launch vehicles for commercial launches to orbit. The company completed its $75 million Series A investment round in May 2021, which was led by DADA Holdings. The current company was formed when the assets of the former company Firefly Space Systems were acquired by EOS Launcher in March 2017, which was then renamed Firefly Aerospace. Firefly's stated purpose is to increase access to space, similar to other private spaceflight companies.
LunIR is a nanosatellite spacecraft launched to the Moon collecting surface spectroscopy and thermography. It was launched as a secondary payload on the Artemis 1 mission on 16 November 2022.
The Lunar Gateway, or simply Gateway, is a space station which is planned to be assembled in orbit around the Moon. The Gateway is intended to serve as a communication hub, science laboratory, and habitation module for astronauts as part of the Artemis program. It is a multinational collaborative project: participants include NASA, the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA), and the Mohammed Bin Rashid Space Centre (MBRSC). The Gateway is planned to be the first space station beyond low Earth orbit.
Blue Moon is a family of lunar landers and their associated infrastructure, intended to carry humans and cargo to the Moon, under development by a consortium led by Blue Origin and including Lockheed Martin, Draper, Boeing, Astrobotic, and Honeybee Robotics. Two versions of Blue Moon are under development: a robotic lander planned to land on the Moon in 2024, and a larger human lander planned to land a crew of four astronauts on the lunar surface for the NASA Artemis V mission in 2029.
Cislunar Explorers is a pair of spacecraft that will show the viability of water electrolysis propulsion and interplanetary optical navigation to orbit the Moon. Both spacecraft will launch mated together as two L-shaped 3U CubeSats, which fit together as a 6U CubeSat of about 10 cm × 20 cm × 30 cm.
EQUULEUS is a nanosatellite of the 6U CubeSat format that will measure the distribution of plasma that surrounds the Earth (plasmasphere) to help scientists understand the radiation environment in that region. It will also demonstrate low-thrust trajectory control techniques, such as multiple lunar flybys, within the Earth-Moon region using water steam as propellant. The spacecraft was designed and developed jointly by the Japan Aerospace Exploration Agency (JAXA) and the University of Tokyo.
ispace Inc. is a publicly traded Japanese company developing robotic spacecraft and other technology to compete for both transportation and exploration mission contracts from space agencies and other private industries. ispace's mission is to enable its clients to discover, map, and use natural lunar resources.
The Artemis program is a Moon exploration program led by the United States' National Aeronautics and Space Administration (NASA), formally established in 2017 via Space Policy Directive 1. It is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars.
The Power and Propulsion Element (PPE), previously known as the Asteroid Redirect Vehicle propulsion system, is a planned solar electric ion propulsion module being developed by Maxar Technologies for NASA. It is one of the major components of the Lunar Gateway. The PPE will allow access to the entire lunar surface and a wide range of lunar orbits and double as a space tug for visiting craft.
The Lunar Terrain Vehicle (LTV) is an unpressurized rover being developed for NASA that astronauts can drive on the Moon while wearing their spacesuits. The development of the LTV is a part of NASA's Artemis Program, which involves returning astronauts to the Moon, specifically the lunar south pole, by 2026, but the LTV will not fly until Artemis V in 2030 at the earliest. The LTV will be the first crewed lunar rover developed by NASA since the Lunar Roving Vehicle used during the Apollo program.
The Habitation and Logistics Outpost (HALO), also called the Minimal Habitation Module (MHM) and formerly known as the Utilization Module, is a scaled-down habitation module as part of the Lunar Gateway. It will be built by Northrop Grumman Innovation Systems. A single Falcon Heavy will launch HALO along with the PPE module and Halo Lunar Communication System, no earlier than 2027.
