LADEE Trajectory Update 10-9-13: 4 hrs to LOI-2

Lunar Orbit Insertion Maneuver 2 (LOI-2) is upon us, scheduled for 09 Oct 2013 10:38 UTC.  This maneuver will lower our periselene altitude from 15700 km down to 2220 km and change our orbit period from 24 hrs to 4 hrs.

The maneuver will last for 220.8 seconds, and will impart a delta-V (change in velocity) of 293 m/sec.

Right now LADEE sees this view:

And the orbit from above would look like this:

From Earth, if you could see the orbit, you’d see this:

Go LADEE!
