Description
LADEE will orbit the Moon for approximately 100 days. Its main objectives are to study the lunar atmosphere and its exospheric dust environment; gaining information about the atmosphere’s composition, its density and variation globally. Three science instruments onboard (UV-Visible and Neutral Mass spectrometers, and a dust instrument) will be used to obtain the above data; essentially giving scientists a look at the current state of the lunar atmosphere, before future lunar missions return.
Also included onboard LADEE is a high performance, space-based communications system known as LLCD (Lunar Laser Communication Demonstration). Operated by NASA, LLCD will test the capability of sending and receiving data as pulses of light at very high rates. The data are directed at Earth-based, ground stations operated by the European Space Agency, which will then redirect the data back up to LADEE again. If the laser communication tests test positive between LADEE and the ground stations, it could lead to the standardisation for a new framework of high-rate, long-distance communication in space.
LADEE was designed, developed, built and tested by NASA Ames Research Center. After the spacecraft reaches the Moon, it will then prepare its science package and systems for eventual operation, and orbit: configuration of which will be near-circular retrograde (clockwise) equatorial, with a period of 113 minutes at some 50 km above the surface. Given a 28-day extension period to its mission in late January 2014, LADEE impacted the lunar surface on the 17 April 2014, where further data may be gleaned from the impact.- JohnMoore2 JohnMoore2
