Lots of touchdown gestures!! Omg!!!!! Those damn onions again!!

eyeball kid

Well done, great achievement.

Touchdown Broncoes!

Congrats to everyone involved

they mentioned 4 minute polling so i guess certain sensors are not streaming constantly,hence the wait for a confirmation after the first result.

Fair play to them

excellent job

@Philae2014: Touchdown! My new address: 67P!

LOL

In just a few minutes, CIVA-P panoramic imaging is programmed to start obtaining first surface images

Can't wait for that image

So I take it this yoke will attach also hoping to travel with it into deep space? How far will it go and be able to send signals back of location? Actually thinking about it, our telescopes probably see way further than this thing will ever go so maybe not much new information from travelling with it?

Thargor

It will probably be destroyed by the sun in a few weeks time.

This and the landing of the Mars rover kinda makes it feel like we're in a golden age of space exploration. The complexity of these missions is staggering. It's mind boggling to realise just how much could go wrong and yet it all went almost perfectly.

Philae cannot contact Earth directly, all comms are through Rosetta. Rosetta is expected to stay alongside the comet for some months yet. I think the nominal mission for Philae is expected to be completed in a few days, but they are hopeful it will last longer than that (think Opportunity and Spirit...)

A bit longer actually:

How long will Rosetta stay with the comet? Will it be incinerated by the sun? If not, how far will the comet take it? Will it end up further away from Earth than Voyager?

Ian Sample replies: The Rosetta mission should last until December 2015, about four months after the comet has made its closest approach to the sun and started to head back out to the more distant reaches of the solar system. The Philae lander could survive for up to three months but its lifetime depends very much on whether it can recharge its batteries once it’s down. And whether it can cling on.

A little RTG on top would have been nice. But hey, we'll be seeing pictures from the surface of a comet for the first time ever! How bad eh??!!

amazing. Can anyone pick up what they are saying ?

Real cool stuff. I think the real question was how are they feeling.:eek: Bloody great stuff. Remember watching Giotto's flyby back in '86, and I thought that was neat.

What speed is the comet travelling at?

Cool. What i take from that is that it won't be heat that kills philae but rather, dust on the solar panels or offgassing of such violence that philae is blown off. Steam on the electronics might become a problem at this stage also so i'm hoping for a very interesting months ahead!!

I was at ESOC at the time and it was pretty neat, although the difference in the technology between now and then is staggering. I did some work on the simulator they used for training the operations staff in the lead up to the encounter.

Curious, why does it list 'Waiting for confirmation of landing' on their web stream?? http://rosetta.esa.int/

Relative to Philae? ... approximately 0 m/s.

It says "Landing confirmed" now, try refreshing the page.

This might be a stupid question, but how come the distance to the Sun is falling but the distance to Earth is rising in that data? i thought this was out by Jupiter?

Apparently the anchors didn't fire.

From Guardian: Apparently the anchors didn’t deploy, so there’s a concern about the stability of the lander.

If the anchors haven't fired then it's goosed surely? As soon as it deploys instruments or tries to drill, it'll drift off?

Theres a little movement also. The feet screws must be in very loose material.
Firing the harpoon will move philae upwards a little too although inertia should help keep things steady. Scared now. Get pics quick!!!

Look at the map near the bottom of that page and imagine that the Earth is moving on it's orbit at about 29km/s while 67p is moving at 16km/s you can see that, for now, Earth is moving away from the comet.

Tnx Javan , you got there before me . :pac:

Edit There are fast forward buttons on the end of that picture to play with Comet position
