Rosetta comet landing due today
Website
European and indeed international co-operation at its finest - with the aim of expanding the horizon of human knowledge. |
Re: Rosetta comet landing due today
Philae is loose ... happy landings.
|
Re: Rosetta comet landing due today
Really looking forward to the landing. Should be at around 4pm I understand.
|
Re: Rosetta comet landing due today
It's looking good. I hope they sort the thruster problem out or I can see it bouncing off the asteroid.
|
Re: Rosetta comet landing due today
Yeah, been anticipating this with excitement for a week. Not read up on the ******** yet but I hope it's not too bad, or else it's another 5 years or more journey till they get to try again...

Re: Rosetta comet landing due today
Webcast froze here just as they started to celebrate!
|
Re: Rosetta comet landing due today
Good job too, I forgot about it and alt-tabbed back right on time to see the start of those celebrations.

Re: Rosetta comet landing due today
Something has always puzzled me, with comets. They're essentially asteroids that get close to the sun, close enough for some material to melt and leave a streaming 'tail' that makes it very visible. If this is the case, each pass must make it lose mass, you'd think after seeing some comet tails that are very long and presumably containing lots of material that after a few passes there wouldn't be any mass left?
|
Re: Rosetta comet landing due today
Yes, they do do that, but their tails are also very un-dense and their mass is huge. Remember this thing is 4km across, the diameter size of a medium size city and heavy enough to have sufficient gravity for a spaceship to orbit it.

Re: Rosetta comet landing due today
It states its an ESA landing. I hope the DWP doesn't find out who worked on it cos they will lose their benefits :-D
|
Re: Rosetta comet landing due today
I read the landing was throwing a hammer from London and hitting a nail in India.
|
Re: Rosetta comet landing due today
Nonsense as usual. That'd be vaguely accurate only if India was the size of the moon and the nail was the size of Europe. Hitting something 4km wide from 30km away is no harder than hitting a bookshelf from the other side of the room, and that bookshelf had a gravity well that sucked everything towards it nomatter where you aimed.
Fact is they don't even have a clue where it landed, they've already lost the damn thing. |

It's got a big enough gravity well for Rosetta to have been orbiting it for the last few months :)
Sure, getting there, from Earth, was a long journey. Being dropped from 30km up and hitting a 4km target that inherently draws everything towards it, isn't a particularly impressive achievement. Coupled with the fact that all three retention mechanisms that were meant to hold the thing down on touchdown failed to operate, and the fact they don't know if they actually hit their target because they can't actually locate where it went... the only thing that'd make the landing impressive is if the lander's odd behavior was because it had been abducted by aliens. Given there's dozens of computer game plugins that can do it at a click of a button, the math behind getting something from A to B in space is actually quite simple. The hard part is building and launching hardware advanced enough and reliable enough to do it, and to be fair, all the important hardware failed today so er... meh. |
Re: Rosetta comet landing due today
Looks like it really is on the surface now, although it may have bounced up to 100 metres back upwards after its first touchdown.

Re: Rosetta comet landing due today
Nah, it bounced twice. First bounce sent it over a kilometre up and it flipped around for a good two hours before the second bounce that was around 100m and 7 minutes long.
Apparently it's now stuck on it's side in a cave and about to die: http://www.dailymail.co.uk/sciencete...bled-side.html |
Re: Rosetta comet landing due today
Gone into sleep mode after sending back it's latest burst of data

Re: Rosetta comet landing due today
It's alive!

First Contact? ;)
|
Re: Rosetta comet landing due today
A whole 85 seconds of connectivity during 6 months.
That level of uptime makes even VM's reliability look spectacular :-P |
Re: Rosetta comet landing due today
I think, if we reflect on many SF books and films, when a robot is re-activated after a period of time without human intervention, this scenario never ends well......

Maybe cosmic radiation will cause it to mutate and return to Earth to wreak terrible revenge on its creators... :erm:
