Rosetta's flyby of Mars; New Horizons' flyby of Jupiter

Big events in space exploration this week:

1. Rosetta made its closest flyby of Mars at 2007-02-25 01:44 UTC. (3650 kilometers away from Mars, 260 kilometers above Martian surface)
2. New Horizons will make its closest flyby of Jupiter at 2007-02-28 05:42 UTC. (2305505 kilometers away from Jupiter)

Here are countdown threads for the Rosetta and the New Horizons missions at NewSMTH BBS. (in Chinese) I had a Perl script that calculating and posting these kind of milestones automatically at BBSes, but unfortunately it had gone forever with my old iBook G4, since I only backed up my home directory before selling it, but left my script at /Library/StartupItems/, so now I have to post at these threads by hand. :(
