I was at a local radio telescope for the “live” event when it landed. Another crazy part was due to the time delay, by the time they were receiving info about entering the Mars atmosphere, it was was already over in reality and we all just had to wait those “minutes of hell” to find out what had happened.
- nine_k 6y agoThere's no such thing as "in the same time" at distances where light propagation delays are comparable to the duration of the event.
- p1mrx 6y agoEarth and Mars are practically stationary, and Occam's razor would say to assume that light travels at the same speed in all directions, even if we can't prove it. So the time of events on Mars has an "obvious", if technically not unique, solution.
- layoric 6y agoFor perceiving the events happening, sure, that was my point. These time differences are nearly always imperceptible but at distances of planets it truly becomes a way of looking into the past. But to be clear, events happen concurrently, eg NASA knew _when_ relative to earth time and _perceived_ events, each stage was "happening" local to Mars vs Earth (assuming it all went well). They made videos about this "7 minutes of terror", I forgot the name of them but linking here [0] [0] https://youtu.be/Ki_Af_o9Q9s https://youtu.be/Ki_Af_o9Q9s
