Just a couple of questions: Are the events being announced on NASA TV the "real" time of events for Opportunity, or the time of events after taking into account the speed of light? Also, what's the speed of light communications delay right now? Thanks to anyone who has the answers...
Hmmm...I assume that the events include the communications delay since they're talking about receive tones indicating certain events. Chris Russell wrote:

Yes, times are ERT (Earth Received Time). Events actually happened nearly 10 minutes before we received confirmation. Patrick Chris Russell wrote:

The Earth-Mars distance is currently 1.33 astronomical units. Taking one astronomical unit as 8 light minutes, this works out to a one-way distance of almost 11 minutes. I don't know the answer to the rest... ---- Jim Cobb james@cobb.name On Jan 24, 2004, at 10:01 PM, Chris Russell wrote:
