The effect of impact may be small, but it will be multiplied with time. It might easily be measurable next orbit, and possibly be enough to "save Earth" after 10 orbits. If the 67P would actually be on trajectory colliding with Earth in 10 orbits, obviously. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 00:30, 2 October 2016 (UTC)

Hairy's Woooo has four o's but Cueball's Wooo has only three o's. Rtanenbaum (talk) 14:41, 30 September 2016 (UTC)
Armegeddon actually had no kinetic impact. The plot device was a bomb drilled into the surface and detonated. This did deflect the comet by splitting it on half along a fault, causing the two pieces to miss Earth.162.158.75.100 17:04, 30 September 2016 (UTC)
Agreed, and edited. Beret Guy (talk) 20:54, 30 September 2016 (UTC)Beret Guy

Hasn't the fact of simply being in orbit already caused a change in the trajectory? Does impact make any difference? 108.162.216.111 (talk) (please sign your comments with ~~~~)

Technically, yes, but the effect is so small it may as well not exist. 108.162.218.239 01:56, 1 October 2016 (UTC)
Yes, the gas(?) expelled from Rosetta in order to accelerate it toward the comet leaves the comet/Rosetta system NotLock (talk) 02:33, 1 October 2016 (UTC)

Question: Why, if the purpose was to collect more data from the comet, was the signal lost, and why are the characters treating this as a good thing? Wouldn't we want a signal from Rosetta in order to transmit the data she gathers? NotLock (talk) 04:01, 1 October 2016 (UTC)

Rosetta has been in orbit around the comet since 2014, gathering data. It sent its lander Philae down in November 2014. This was always the intended ending for the orbiter itself. Miamiclay (talk) 04:38, 1 October 2016 (UTC)
Thanks for the response! So the "extra data from Rosetta's sensors" were transmitted as Rosetta was descending, but before she landed. After she landed, then communications were shut off. Is that correct? NotLock (talk) 05:28, 1 October 2016 (UTC)
I'm not sure whether comms were 'shut off,' or if they just knew that they'd get no more from the surface because of issues with solar power or line of sight once it was on the surface, but this was the plan IIRC. Miamiclay (talk) 23:36, 1 October 2016 (UTC)
