Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never mor ...

Block D
Blok D (russian: Блок Д meaning Block D) is an upper stage used on Soviet and later Russian expendable launch systems, including the N1, Proton-K and Zenit.
The stage (and its derivatives) has been included in more than 320 launched roc ...
lunar orbit insertion
In astronomy, lunar orbit (also known as a selenocentric orbit) is the orbit of an object around the Moon.
As used in the space program, this refers not to the orbit of the Moon about the Earth, but to orbits by spacecraft around the Moon. The ...
/descent stage by simulating the lunar orbit insertion burn, the lunar orbit circularization burn and the final lunar descent burn. Over the course of five days, the Block D stage was ignited three times to raise the initial ~190 km × ~300 km × 51.6° orbit to a final 2577 km × 5082 km × 55.87° orbit. The Block D stage was fitted with cameras in the tanks to monitor the fuel and oxidizer behaviour in weightlessness and during acceleration. Kosmos-382 also carried other experiments, including a prototype environmental control subsystem named "Rosa" for producing potable water from atmospheric condensate exhaled by cosmonauts onboard Soviet manned spacecraft. This system was later used on the
