Italics fail. Only Greg Laden’s line from #8 was intended to be italicised. Sigh.

@8. Greg Laden : “what will be the effects of both the impact and the added mass on the comet’s orbit?”

Negligable. The impact was very low speed indeed relatively and the mass of Philae is exceptionally low so basically none. Much less than the cometary jetting which can slightly change its course over time.

Now, what will be the effects of both the impact and the added mass on the comet’s orbit?

You bastards. You’ve killed us all…

It also has screws to help hold it in place. (Gravity exists but is very weak on a body as small as a comet.)

Shortly after landing was confirmed, the probe tweeted: “Touchdown! My new address: 67P!” Later, it tweeted again: “I’m on the surface but my harpoons did not fire.”

That was also in an update at 11:50 on the NPR feed. I haven’t heard any news since. The reports were that it was a soft landing and other than the “harpoons” all was good.

Philae is on its comet with a successful landing. Congratulations to all those who made her – and Rosetta fly – and land. 🙂
