Philae landing: touchdown highlights


Highlights from coverage of ESA’s Rosetta mission soft-landing its Philae probe on a comet, the first time in history that such an extraordinary feat has been achieved.

After a tense wait during the seven-hour descent to the surface of Comet 67P/Churyumov–Gerasimenko, the signal confirming the successful touchdown arrived on Earth at 16:03 GMT (17:03 CET).

  1. Thank you for the riport. My only question is: We saw the happy people on the video but we could not see the touch down in live broadcast . Why not?  45 years ago in 1969 we saw the live broadcast of the landing on the moon.

  2. Now it has happened and a few things don't fit.
    1) There cannot have been a bounce, while yet landing. The force of the bounce is F = m.a, (Newton's second law), where m is Philae's mass of around 100 kg. This force must be far greater than the 1 gram-force (weight) that the comet's gravity yields; Philae would have been catapulted back into space.
    2) Philae would now be balancing on two feet only, the third having no support. This can't be true either, being out of gravity center – the thing would roll over.

    I suspect the landing went as planned, but we are not to know that, because then "they" would have to show the public high-resolution close-ups of the surrounding surface and other discovery information, which they don't want to. Surely Philae's ROLIS camera pictured the descent views on the comet, including touch-down, which aren't published either, most frustrating! To it the shadow story, now depriving Philea from having solar power, so it will  go into hibernation. This cover-up story "explains" why the public won't see anything, while in reality everything works as planned – a secret mission!

  3. Wow. I'm extremely happy to see the mission succeed! Before the landing, I saw no real shots aside from the animation demonstration of Rosetta landing but when the black & white image flashes on the screen, I was totally in awe. It's the real thing man! It has finally landed! 

  4. Your incredibly skilled team of scientists, heros of this century done amazing work.Once again congrats. Really this will be an inspiration to the younger generations particularly youth prefer to opt/choose  for scientific carer.Rosetta and lander i feel in the coming months may be facing most increasingly hazardous dust , unexpected variations and radiation leaving the nucleus to form the coma, and malfunction of scientific instruments on board the rosetta and lander.Camer lenses mostly might have covered by heavy dust and particles giving blurring images.

  5. Jean-Pierre Bibring (the guy who kind of looks like Einstein at the beginning of the video) was my professor of Initiation to Astrophysics last year :p
