Oh dear, someone on the Daily Mail science page is saying that Philae is going to doom us all, by changing the orbital path of the comet. ...where do people get their ideas of physics from?
Has anyone told them that Philae weighs about 1 gram or 1 ounce on 67P, depending on who's telling the story?
This topic made me try to find the 10-year-old BAUT thread where someone asked if it was theoretically possible for an astronaut, using rocket principles, to pee himself off an asteroid -- assuming he wasn't encumbered by a pressure suit. JayUtah came up with all the maths involved.
Unfortunately the CosmoQuest forum won't accept any of the words in the thread's title for doing a search, which makes it a pretty useless search "facility." The name of the thread was "Secret NASA Images Hide Hoax". Time to try Google.
