The Chang’e-5T Service Module Is Off to Deep Space; Will Return to the Moon
6 November 2014
LPAC —After releasing the Return Module that landed back on Earth Nov. 1, the Service Module on the Chang’e-5T mission, which does not come back, has been reassigned a mission further in space. It is headed to the Earth-Moon L-2 libration point, where, 37,000 miles past the Moon, there is a gravitational balance between the Earth and Moon. A spacecraft can "park" there, virtually motionless. The Chang’e-2 lunar orbiter was similarly re-purposed, sent to the L-2 point, and then on to a fly-by of near-Earth asteroid, Toutatis. But space scientist Emily Lakdawalla reports today that, according to China Military Online, the Chang’e-5T Service Module will not stay at the L-2 point, or travel further, but will return to lunar orbit. It then could provide communications support for China’s future missions to the Moon. Lakdawalla explains that with an orbiter in place, a future Chinese lunar lander would not be limited to sites that are in line-of-sight with the Earth, but could even be placed on the lunar far-side, which is poorly explored, never seen from Earth. There is speculation that there will be a Chang’e-4 mission, which would re-do, likely with significant up-grades, a lunar lander and rover mission, to augment what was learned on the Chang’e-3 lander and Yutu mission, last December.
