LADEE Update 10-07-13: Safe in Lunar Orbit after LOI-1

The LADEE Spacecraft successfully performed Lunar Orbit Insertion maneuver 1 (LOI-1) on Oct. 6, 2013 3:57 PDT. The LOI-1 maneuver captured LADEE into a 24 hr orbit. After 3 days (and 3 revs) in the capture orbit, the spacecraft will perform LOI-2 on Oct. 9 at 3:37 PDT. The second of 3 Lunar Orbit Insertion […]

LADEE in Lunar Orbit

The LADEE spacecraft is now in Lunar orbit. Tracking data will later confirm the precise parameters of the orbit, but based on telemetry of thruster performance and accelerations, the LOI-1 burn appears to be close to nominal.

The planned Lunar orbit has an orbit period of 23.1 hrs. The next planned maneuver (Lunar Aposelene Maneuver […]

LADEE Lunar Orbit Insertion 1 (LOI-1)

Watch the Lunar Orbit Period and Lunar Apoapsis Altitude come down once the Lunar Eccentricity goes below 1.0 (from Hyperbolic to Elliptical).

LADEE Now in the Moon’s Sphere

The Moon is now under control. Based on LADEE’s altitude (below 66,000 km) the Moon is now the primary gravitational body acting on the spacecraft. In other words, the Moon’s gravity is now stronger than the Earth’s.



This picture really shows the change the Moon is imposing on the orbit, which until […]
