Lunar transfer, perspective view. TLI occurs at the red dot near Earth. A trans-lunar injection (TLI) is a propulsive maneuver, which is used to send a spacecraft to the Moon. Typical lunar transfer trajectories approximate Hohmann transfers, although low-energy transfers have also been used in some cases, as with the Hiten probe. [1]
Old School RuneScape is a massively multiplayer online role-playing game (MMORPG), developed and published by Jagex.The game was released on 16 February 2013.

The Lunar Exploration Ground Sites, or LEGS, are several NASA space communication complexes created to support lunar exploration. They are in addition to the existing NASA Deep Space Network and the Near Earth Network. The LEGS mission is to provide direct-to earth communication and navigation services for missions operating from 36,000 ...
Representation of the lunar gravity well, illustrating how resources needed only for the trip home don't have to be carried down and back up the "well". The main advantage of LOR is the spacecraft payload saving, due to the fact that the propellant necessary to return from lunar orbit back to Earth need not be carried as dead weight down to the Moon and back into lunar orbit.
The Luna programme was the first successful lunar programme, its Luna 1 (1959) being the first partially successful lunar mission The first image taken of the far side of the Moon, returned by Luna 3 (1959) Missions to the Moon have been numerous and include some of the earliest space missions, conducting exploration of the Moon since 1959.
Most lunar low orbits below 100 km (60 mi) are unstable. [2]Lunar Module Eagle in lunar orbit during Apollo 11, July 1969. Gravitational anomalies slightly distorting the orbits of some Lunar Orbiters led to the discovery of mass concentrations (dubbed mascons) beneath the lunar surface caused by large impacting bodies at some remote time in the past.
Luna 26 (Luna-Resurs-Orbiter [3] or Luna-Resurs O [4]) is a planned lunar polar orbiter, part of the Luna-Glob program, by Roscosmos.In addition to its scientific role, the Luna 26 orbiter would also function as a telecomm relay between Earth and Russian landed assets. [1]
On 9 March 2021, China and Russia signed a “Memorandum of Understanding between the Government of the People’s Republic of China and the Government of the Russian Federation Regarding Cooperation for the Construction of the International Lunar Research Station.” [14] On 16 June 2021, Roscosmos and the China National Space Administration (CNSA) held a joint session in St. Petersburg ...
