LADEE trajectory update 10-5-13 12:00 PDT

LADEE continues to approach the Moon, now nearing 100,000 km in altitude.




Note the last few parameters on the left.  Lunar orbit period is zero (hyperbolic still), as is the Lunar Altitude of Apoapsis.  The Lunar Altitude of periapsis isn’t accurate either, as the spacecraft is still mostly in Earth orbit.  The Lunar disk is getting larger, and the Earth disk smaller:




This shot shows the upcoming portion of the trajectory, when the Earth-bound trajectory is taken over by Lunar gravity:




The final shot is the best, our Lunar approach:
