t. e. The Artemis program is a Moon exploration program that is led by the United States' National Aeronoautics and Space Administration (NASA) and was formally established in 2017 via Space Policy Directive 1. The Artemis program is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 moon mission in 1972.
Human Landing System. A Human Landing System ( HLS) is a spacecraft in the U.S. National Aeronautics and Space Administration's (NASA) Artemis program that is expected to land humans on the Moon. These are being designed to convey astronauts from the Lunar Gateway space station in lunar orbit to the lunar surface, sustain them there, and then ...
Starship HLS. Starship HLS (Human Landing System) [a] is a lunar lander variant of the Starship spacecraft that is slated to transfer astronauts from a lunar orbit to the surface of the Moon and back. It is being designed and built by SpaceX under the Human Landing System contract to NASA as a critical element of NASA's Artemis program to land ...
A Moon landing or lunar landing is the arrival of a spacecraft on the surface of the Moon, including both crewed and robotic missions. The first human-made object to touch the Moon was Luna 2 in 1959. [3] In 1969 Apollo 11 was the first crewed mission to land on the Moon. [4]
For attitude control (orientation), the spacecraft uses 12 thrusters (45 N each) also powered by MON-25/MMH. The spacecraft's avionics incorporate guidance and navigation to the Moon, and a Doppler LiDAR to assist the automated landing on four legs. From Mission 2, its landing ellipse will be 100 m x 100 m, down from 24 km × 6 km previously.
The Apollo Lunar Module ( LM / ˈlɛm / ), originally designated the Lunar Excursion Module ( LEM ), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only ...
Landing. Landing is the last part of a flight, where a flying animal, aircraft, or spacecraft returns to the ground. When the flying object returns to water, the process is called alighting, although it is commonly called "landing", "touchdown" a or "splashdown" as well. A normal aircraft flight would include several parts of flight including ...
A Mars landing is a landing of a spacecraft on the surface of Mars. Of multiple attempted Mars landings by robotic, uncrewed spacecraft, ten have had successful soft landings. There have also been studies for a possible human mission to Mars including a landing, but none have been attempted. As of 2023, the Soviet Union, United States and China ...
