From NASA news:
NASA Announces Mars Mission Briefing
NASA will brief news media about the Mars Reconnaissance Orbiter mission at 1 p.m. EST, Friday. The event is in NASA’s auditorium, 300 E Street SW, Washington.
The NASA spacecraft is scheduled to arrive at Mars on March 10, 2006. It will provide more information about the planet than all previous NASA Mars missions combined. Participants will address mission goals and the sequence of events necessary to successfully place the vehicle into orbit around Mars.
The briefing will run live on NASATV. Man, I love NASATV.
For more about the Mars Reconnaissance Orbiter mission, see the mission home page at NASA.
If anyone has a Celestia script for this mission, please let me know. If I find one I will post it here.
