I'm working on a java applet that simulates the MRO trajectory. It "works on my machine" but I think it breaks on other platforms. One issue is that it requires the Java runtime environment JRE1.5 & will fail on JRE1.4. Could someone here try it and say whether it worked for them or not? Here's the link:

In timeline at marsrecon.com,
Are you sure the altitude at arrival will be 428 km? Since my calculation at JPL Horizons gave 329 km above the surface. |

The Horizons website is using the SPK kernel file MRO_p_c_ref-od010_050812_060401_p-v1 whereas I'm using spk_moi_ideal_051123_060320_p-v1.bsp. The latter was released on Feb. 15 & I believe represents the latest information, but who knows. During the press conference a couple weeks ago I think someone on the panel mentioned that the closest approach would be "500 km"--just to muddy the waters further! -------------------- |

The predict after TCM2 for closest approach during MOI was a little over 500 km. Note that the periapsis on the next orbit is typically lower by something like 80 km. They can raise this with a maneuver near the first apoapsis if needed. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
