purpleivan Posted September 6, 2019 Share Posted September 6, 2019 Is it expected that there's no velocity stats update at this stage. Quote Link to comment Share on other sites More sharing options...
tater Posted September 6, 2019 Share Posted September 6, 2019 That telemetry freeze cannot be good. Just now, purpleivan said: Is it expected that there's no velocity stats update at this stage. Oh? OK then... This doesn't seem... nominal. Quote Link to comment Share on other sites More sharing options...
purpleivan Posted September 6, 2019 Share Posted September 6, 2019 (edited) That's what I thought... I'd have thought it would have made it to the surface by now. Wondering if there's been a similar problem to beresheet on engine restart. Edited September 6, 2019 by purpleivan Quote Link to comment Share on other sites More sharing options...

MinimumSky5 Posted September 6, 2019 Share Posted September 6, 2019 The lander was doing some very odd somersaults on the live telemetry, so I think that it was either a computer issue, or an engine failure. Quote Link to comment Share on other sites More sharing options...

ThatGuyWithALongUsername Posted September 6, 2019 Share Posted September 6, 2019 (edited) Well... at least it was going a bit slower then Beresheet was... I don't think they've officially said anything as they're waiting on data, but Vikram's fate seems all too obvious at this point...

purpleivan Posted September 6, 2019 Share Posted September 6, 2019 There was something said just before the data was lost about "giving permision for the 2nd burn", so I guess the decent might not be entirely automated (i.e. without "permission" the engine might not restart). If it is fully autonomous, there's at least a chance it made it down, but is out of contact... not holding out hope though. Quote Link to comment Share on other sites More sharing options...

purpleivan Posted September 6, 2019 Share Posted September 6, 2019 Yeah... I noticed that the guy in the foreground of some shots (fairly young, short hair and blue hooded top) looked unhappy pretty early on. Quote Link to comment Share on other sites More sharing options...
StrandedonEarth Posted September 6, 2019 Share Posted September 6, 2019 Somersaults, hmmm? Off the top of my head, some sensor for determining orientation started hallucinating... Looks like it will rest in pieces, like so many other first landing attempts. Better luck next time! i know it’s early to write it off already, but it doesn’t sound good.

purpleivan Posted September 6, 2019 Share Posted September 6, 2019 On the plus side, while waiting for things to get moving with the landing this evening, I found a story on CNN.com about someone accidentally getting charged $67,000 for a beer in a bar I've been in a few times.

VoidCosmos Posted September 7, 2019 Share Posted September 7, 2019 Vikram may be having an automated landing system. So it may have landed but it....... It may be transmitting data to the ground stations. Quote Link to comment Share on other sites More sharing options...

tater Posted September 7, 2019 Share Posted September 7, 2019 Wonder what they can figure out about the failure, given the telemetry loss. If everything was indeed nominal up to the data cutout---which I think is false---they might have little to go on. I assume it was using an omni antenna to the orbiter above, so spacecraft attitude should not have been a problem for comms, right? Assuming it was in communication in an expected way, the sudden loss suggests a catastrophic failure, or a profound power loss. If the antenna was directional, then an attitude issue could cause comms dropout (and also a crash). The last telemetry on the screen we saw had it diverging from the ideal trajectory, but still inside the acceptable range (assuming that was the lines on either side). Hopefully they have the data they need. Quote Link to comment Share on other sites More sharing options...
