List Of Probes By Operational Status
This is a list of active space probes which have escaped Earth orbit. It includes lunar space probes, but does not include space probes orbiting at the Sun–Earth Lagrangian points (for these, see List of objects at Lagrangian points). A craft is deemed "active" if it is still able to transmit usable data to Earth (regardless of whether it can receive commands). The craft are further grouped by mission status – "en-route", "mission in progress" or "mission complete" – based on their primary mission. For example, though ''Voyager 1'' is still contactable en-route to the Oort Cloud and has exited the Solar System, it is listed as "mission complete" because its primary task of studying Jupiter and Saturn has been accomplished. Once a probe has reached its first primary target, it is no longer listed as "en route" regardless of whether further travel is involved. Missions in progress Moon * ARTEMIS P1/P2 ** Mission: studying the effect of the solar wind on the Moon. Originall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Halo Orbit
A halo orbit is a periodic, non-planar orbit associated with one of the L1, L2 or L3 Lagrange points in the three-body problem of orbital mechanics. Although a Lagrange point is just a point in empty space, its peculiar characteristic is that it can be orbited by a Lissajous orbit or by a halo orbit. These can be thought of as resulting from an interaction between the gravitational pull of the two planetary bodies and the Coriolis and centrifugal force on a spacecraft. Halo orbits exist in any three-body system, e.g., a Sun–Earth–orbiting satellite system or an Earth–Moon–orbiting satellite system. Continuous "families" of both northern and southern halo orbits exist at each Lagrange point. Because halo orbits tend to be unstable, station-keeping using thrusters may be required to keep a satellite on the orbit. Most satellites in halo orbit serve scientific purposes, for example space telescopes. Definition and history Robert W. Farquhar first used the name " ...

Lunar Water
The search for the presence of lunar water has attracted considerable attention and motivated several recent lunar missions, largely because of water's usefulness in making long-term lunar habitation feasible. The Moon is believed to be generally anhydrous after analysis of Apollo mission soil samples. It is understood that any water vapor on the surface would generally be decomposed by sunlight, leaving hydrogen and oxygen lost to outer space. However, subsequent robotic probes found evidence of water, especially of water ice in some permanently shadowed craters on the Moon; and in 2018 water ice was confirmed in multiple locations.Water and Ices on the Moon" ''science.nasa.gov'', fetched 11 June 2024 This water ice is not in the form of sheets of ice on the surface nor just under the surface, ...

Lunar Resources
An artificially colored mosaic constructed from a series of 53 images taken through three spectral filters by ''Galileo's'' imaging system as the spacecraft flew over the northern regions of the Moon on 7 December 1992. The colors indicate different materials. A lunar anorthosite rock collected by the Apollo 16 crew from near the crater Descartes The Moon bears substantial natural resources which could be exploited in the future. Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that, together, might enable lunar habitation. The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration and beyond.M. Anand, I. A. Crawford, M. Balat-Pichelin, S. Abanades, W. van Westrenen, G.

Korea Aerospace Research Institute
The Korea Aerospace Research Institute (KARI; ), established in 1989, is the aeronautics and space agency of South Korea. Its main laboratories are located in Daejeon, in the Daedeok Science Town. KARI's vision is to continue building upon indigenous launch capabilities, strengthen national safety and public service, industrialize satellite information and applications technology, explore the Moon, and develop environmentally-friendly and highly-efficient cutting-edge aircraft and core aerospace technology.

Korea Pathfinder Lunar Orbiter
The Korea Pathfinder Lunar Orbiter (KPLO), officially Danuri, is South Korea's first lunar mission. The orbiter, its science payload and ground control infrastructure are technology demonstrators. The orbiter will also be tasked with surveying lunar resources such as Lunar water, water ice, uranium, helium-3, silicon, and aluminium, and produce a topographic map to help select future lunar landing sites. The mission was launched on 4 August 2022 on a Falcon 9 Block 5 launch vehicle. It was inserted into orbit around the Moon on 16 December 2022 (UTC). Name On 23 May 2022, the South Korean Ministry of Science and ICT officially named the Korea Pathfinder Lunar Orbiter (시험용 달 궤도선, 試驗用月軌道船) as "Danuri" (다누리). Danuri is a portmanteau of two Korean words, ''dal'' (달) which means moon and ''nurida'' (누리다) which means enjoy. According to the ministry, this new name implies a big hope and desire for the success of South Korea's fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near-rectilinear Halo Orbit
In orbital mechanics a near-rectilinear halo orbit (NRHO) is a halo orbit that passes close to the smaller of two astronomical object, bodies and has nearly stable behavior. The CAPSTONE mission, launched in 2022, is the first spacecraft to use such orbit in cislunar space, and this Moon-centric orbit is planned as a staging area for future lunar missions. In contrast with low lunar orbit which NASA characterizes as being deep in the lunar gravity well, NRHO is described as being "balanced on the edge" of the gravity well. The NRHOs are a subset of the halo families. This orbit type could also be used with other Minor planet, bodies in the Solar System and beyond. Association with Lagrange points A halo orbit is a periodic, three-dimensional orbit associated with one of the Lagrange points. Near-rectilinear means that some segments of the orbit have a greater curvature than those of an elliptical orbit of the same maximum diameter, and other segments have a curvature less t ...

Lunar Gateway
The Lunar Gateway, or simply Gateway, is a planned space station which is 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. However, the Second presidency of Donald Trump, Trump administration has called for ending the Gateway program in its 2026 budget proposal. The science disciplines to be studied on the Gateway are expected to include planetary science, astrophysics, Earth observation, heliophysics, Astrobiology, fundamental space biology, and Health, human health and performance. As of April 2024, construction is underway o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
