"Pseudo-MPEC" for LCROSS
Created Wed Sep 16 17:28:36 2009 using Find_Orb
You can get ephemerides for this object from the Minor Planet Center's Distant Artificial Satellites Observation page, or from JPL's Horizons system, customized for your observing location and desired time span. The former is quicker and easier to use. The latter can give you some additional details the MPC doesn't supply. (The following ephemerides are geocentric, only suited for giving you a rough idea as to what's going on.)
This shows LCROSS data for times after 24 August, when the malfunction occurred that resulted in loss of most of its propellant. You can click here for the data between 22 July, when LCROSS made the maneuver that put it on course to hit the moon, and the misfire. According to Horizons, this maneuver was made sometime around 21 July 13:00 UT. You can also click here for the initial data after launch and before 22 July, including elements near launch and the first lunar flyby.
As the impact elements show, we again have enough data to compute an impact point on the moon. In fact, the impact point is accurate to within about three kilometers. However, at least one more maneuver is planned for sometime around 25 September, to nudge LCROSS toward its target crater of Cabeus A (at latitude -81.55, longitude 316.90 East.)
Here's a map of the probable impact area. It's a bit south of the impact area before the malfunction (and a heck of a lot smaller). I think the plan was for a far southern impact anyway, so at least the thrust was in the right direction.
TLEs (Two-Line Elements) (updated 8 September): Some programs will allow one to display Earth-orbiting satellites using elements in the TLE format. Here are TLEs for LCROSS. The satellite model used for TLEs is really intended for low-earth, geosynchronous, or 12-hour satellites, and doesn't work over long time spans for LCROSS-like objects. To overcome this, I've provided elements for one-day intervals covering most of the LCROSS mission. Pick the elements corresponding to your date of interest. For that day only, the maximum error in kilometers will correspond to the 'Worst residual' shown for that day (usually about 60 kilometers, or less than an arcminute at the distance of LCROSS.) Use it outside that range, and things fall apart rapidly. Also, be warned that TLEs aren't provided after 5 October. The program I wrote to compute TLEs choked on those data, giving a divergent (completely meaningless) solution.
