Subject: LADEE Trajectory to LOI

ATIG Members-

Friday night, NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE)
spacecraft was launched from the Wallops Flight Facility by a Minotaur V
rocket on a month-long multi-orbit trajectory to the Moon.  Liftoff was on
time September 6 at 11:27 PM EDT, and the reported trans-lunar trajectory
was nominal.  I'm therefore enclosing Earth-centered and Moon-centered
inertial trajectory plots of the planned nominal trajectory leading to lunar
orbit insertion (LOI) on October 6.  Data supporting these plots were posted
to JPL's Horizons ephemeris service on August 30.

According to a report posted to http://www.nasa.gov/LADEE/#.Uis62OB0org at
3:40 AM EDT on September 7, mission controllers are working an anomalous
shutdown of LADEE's attitude control reaction wheels, but communications
with the spacecraft are still being maintained.  The nominal trans-lunar
trajectory appears to be very flexible in achieving LOI, so there is ample
time to work this problem.  If any significant trajectory updates are
posted, I'll make every effort to pass along updated plots.
