A lander is a spacecraft that descends towards, then comes to rest on the surface of an astronomical body other than Earth. In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional.
ExoMars is an astrobiology programme of the European Space Agency (ESA).
A Moon landing or lunar landing is the arrival of a spacecraft on the surface of the Moon. This includes both crewed and robotic missions. The first human-made object to touch the Moon was the Soviet Union's Luna 2, on 13 September 1959.
A lunar lander or Moon lander is a spacecraft designed to land on the surface of the Moon. As of 2023, the Apollo Lunar Module is the only lunar lander to have ever been used in human spaceflight, completing six lunar landings from 1969 to 1972 during the United States' Apollo Program. Several robotic landers have reached the surface, and some have returned samples to Earth.
The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it.
Crew Space Transportation System (CSTS), or Advanced Crew Transportation System (ACTS), was a proposed design for a crewed spacecraft for low Earth orbit operations such as servicing the International Space Station, but also capable of exploration of the Moon and beyond. It was originally a joint project between the European Space Agency (ESA) and the Roscosmos, but later became solely an ESA project. This study was conceived as a basic strategic plan to keep a viable European human spaceflight program alive.
Luna-Glob is a Moon exploration programme by Roscosmos meant to progress toward the creation of a fully robotic lunar base. When completed, the programme is intended to continue with crewed lunar missions, starting with a crewed orbiter spacecraft called Orel.
A moonbase is a facility on or below the surface of the Moon, enabling human activity on the Moon. As such, it is different from a lunar space station in orbit around the Moon, like the planned Lunar Gateway of the Artemis program. Moonbases can be for robotic or human use, in both cases not necessarily including lunar habitation facilities. A base might be a step towards colonization.
The lunar south pole is the southernmost point on the Moon. It is of interest to scientists because of the occurrence of water ice in permanently shadowed areas around it. The lunar south pole region features craters that are unique in that the near-constant sunlight does not reach their interior. Such craters are cold traps that contain a fossil record of hydrogen, water ice, and other volatiles dating from the early Solar System. In contrast, the lunar north pole region exhibits a much lower quantity of similarly sheltered craters.
Mars-Grunt, also known as Expedition-M, is a robotic Mars sample return mission proposed to be sent to Mars in mid-2020s. It was proposed to the Russian Federal Space Agency (Roscosmos) by the Russian Space Research Institute.
The Chandrayaan programme also known as the Indian Lunar Exploration Programme is an ongoing series of outer space missions by the Indian Space Research Organization (ISRO) for the exploration of the Moon. The program incorporates a lunar orbiter, an impactor, a soft lander and a rover spacecraft.
Luna 27 is a planned lunar lander mission by the Roscosmos with collaboration by the European Space Agency (ESA) to send a lander to the South Pole–Aitken basin, an area on the far side of the Moon. Its objective will be to detect and characterise lunar polar volatiles. The mission is a continuation of the Luna-Glob programme.
The Lunar Gateway, or simply Gateway, is the first planned extraterrestrial space station. It will be placed in lunar orbit and is intended to serve as a solar-powered communication hub, science laboratory, and short-term habitation module for government-agency astronauts, as well as a holding area for rovers and other robots. It is a multinational collaborative project involving four of the International Space Station partner agencies: NASA, European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), and Canadian Space Agency (CSA). It is planned to be both the first space station beyond low Earth orbit and the first space station to orbit the Moon.
Luna 25 was a failed Russian lunar lander mission by Roscosmos in August 2023 that planned to land near the lunar south pole, in the vicinity of the crater Boguslawsky.
Resource Prospector is a cancelled mission concept by NASA of a rover that would have performed a survey expedition on a polar region of the Moon. The rover was to attempt to detect and map the location of volatiles such as hydrogen, oxygen and lunar water which could foster more affordable and sustainable human exploration to the Moon, Mars, and other Solar System bodies.
Luna 28 is a proposed sample-return mission from the south polar region of the Moon.
The Lunar Polar Exploration Mission (LUPEX) or Chandrayaan-4 is a planned joint lunar mission by the Indian Space Research Organisation (ISRO) and Japan Aerospace Exploration Agency (JAXA). The mission would send an uncrewed lunar lander and rover to explore the south pole region of the Moon no earlier than 2026. JAXA is likely to provide the under-development H3 launch vehicle and the rover, while ISRO would be providing the lander.
HERACLES is a planned robotic transport system to and from the Moon by Europe (ESA), Japan (JAXA) and Canada (CSA) that will feature a lander called the European Large Logistic Lander, a Lunar Ascent Element, and a rover. The lander can be configured for different operations such as up to 1.5 tons of cargo delivery, sample-returns, or prospecting resources found on the Moon.
The International Lunar Research Station (ILRS) (Chinese: 国际月球科研站) is a planned lunar base currently being led by Roscosmos and the China National Space Administration (CNSA). The ILRS will serve as a comprehensive scientific experiment base built on the lunar surface or in lunar orbit that can carry out multi-disciplinary and multi-objective scientific research activities including exploration and utilization, lunar-based observation, basic scientific experiment and technical verification, and long-term autonomous operation. Statements from Roscosmos and CNSA underline that the project will be "open to all interested countries and international partners."
