Radio signals from Rosetta flatlined at 7:19 a.m. Eastern after it did a soft belly-flop onto Comet 67P/Churyumov-Gerasimenko at a speed of two miles per hour, slower than the average walk. For the last few minutes, people at the European Space Operations Center in Darmstadt, Germany, watched their computer screens mostly in silence, but with some nervous chatter. When the radio signals ceased, they applauded and hugged in a celebration that was part joyous, part somber. “This is it,” said Patrick Martin, the mission manager. “I can announce the full success of this historic descent of Rosetta toward 67P, and I declare the primary mission operations ended for Rosetta.”[/quote] [quote]At the end of Thursday’s presentations, Matt Taylor, the project scientist, thanked the other scientists who he said “worked their guts out to get to where we are today.” He said they had mixed feelings: sad about Rosetta’s demise, and eager to take a deeper look at the reams of data. ”The operations end,” Dr. Taylor said, “but we still have all this science to do, so they’re still happy that we got to this stage.”[/quote] The final image taken by Rosetta, just before it collided with the comet: [img]http://i.imgur.com/stDfD1Y.jpg[/img]
Was there a specific reason to crash it into it? "Feel" the density?
goddamnit stop anthropomorphise probes that always had a sucidial mission in mind! the whole thing is gonna get knocked off when the surface is shed when the comet gets close to the sun
This is not how the animation described it I need a hug and loads of ice cream
It's ok, they're just sleeping. :cry:
Stop probe abuse
Was thinking "Rosetta probe does amazing impression of Trump's campaign" but we've got enough Trump threads already
[video=youtube;vcYo-qQ5HbA]https://www.youtube.com/watch?v=vcYo-qQ5HbA[/video] A really nice touch I noticed, at the end of this video [sp]the two people are based of the characters from the short film Ambition which the ESA made for Rosetta & Phelie arriving at 67P (https://www.youtube.com/watch?v=H08tGjXNHO4) [/sp]

[QUOTE=Xyrec;51131869]I wonder if those are boulders or small rocks. Does anyone know?[/QUOTE] Assuming they're pretty small since it's so out of focus (and likely close)
[QUOTE=Orki;51131723]Was there a specific reason to crash it into it? "Feel" the density?[/QUOTE] Crashing is also part of the safing procedure. There is not enough fuel to leave the comet reliably and if left in free orbit, it's possible it would at some point collide and spread its propellant and debris all over it. While there is no immediate concern, safing permits the comet to stay untainted by all the possible debris.
