I always leaned toward ERT times when it comes to things like these. Even though I acknowledged the fact that from the spacecraft point of view events happen in SCET, it is us who are observers in this case and, for us, saying the actual event took place some time before is simply philosophical and not particularly useful. We simply cannot know whether Phoenix landed safely until that information propagates to us so for all practical purposes, it doesn't even happen by then in our frame of reference.
Just as saying if the sun stopped shining right now (from its point of view), the actual event wouldn't happen for us for another 8 minutes and there is no way for us to know it will stop shining in the next 8 minutes. -------------------- |

I do NOT mind the sun stopping right now but, please, do NOT stop the Internet -------------------- |

I'm no scientist, but I have a sneaking suspicion that if the Sun DID go out it might have some repercussions for net access Climber, like, oh, I don't know, THE WORLD ENDING?!?!?!?!?!?!?!?!?!?!?
 I know what you mean tho... I'm looking at my PC right now thinking "Don't you DARE pull anything stupid on me today..."

QUOTE (Tman @ May 25 2008, 10:24 AM) There's a site from a nice guy (Neil Walker) that provides NASA TV up to 1200 kbits (or 2300 by using Microsoft Silverlight). That's awesome quality! Two questions: 1) Which NASA TV channel is that? 2) Is there a simple way to save this (or other wmv LIVE) stream to HD directly while watching? I want to have this saved for future viewing! -------------------- |

If all goes well, this will be:
1) First time since Dec 25, 1978 that three spacecraft have operated on the surface of other planets. 2) First time since Jan 14, 2005 that three spacecraft have operated on the surface of other worlds. 3) First time ever that three spacecraft have operated on the surface of the same other planet. |

Anyone else having problems with the 1,200k NASA feed. Yesterday it played fine but now the video keeps freezing.

I'm using the 500k feed as well, the 1.2M feed seems to switch down to lower bitrates constantly, causing skips and delays.

I watched the briefing here, and the quality was very good. Excellent on full screen...
