After ten years, five months and four days

Yup, that deserves a 'Newsflash' all right...

Finally, some actual astronomy news.

These "Ongoing methodical process yields a small amount more unremarkable data, EVERYBODY CELEBRATE!!" threads were killing me.

'Yep, it's a comet.'  Great Success.

Rosetta, stone.
Stone, this is Rosetta.

We launch all kinds of rockets to get all kinds of knowledge
But the thrill we've never known
Is the thrill that'll getcha when your takin' a picture 
with Rosetta on an icy stone...

Oh geez, now that a human probe has arrived I bet the climate is going to change rapidly.

TFA says it is the first spacecraft to rendezvous with a comet

Didn't we humans already smash a spacecraft (or a dedicated part of the spacecraft) into a comet to see what was inside by analyzing the resulting plume?

I suppose it depends on your definition of "rendezvous". Going into a controlled orbit versus smashing into it - slightly different calculations involved.

Actually, the same basic calculations, just different inputs and outputs.

Instead of putting a rover on Mars or going to a comet, why not try Europa to discover life in our solar system?

:) Either way, smashing into it just means meeting it at the same point in space and time. Rendezvous with it means meeting with it at the same point in space and time and velocity. You have to be going to same speed as the comet to rendezvous. Which is why we picked a relatively slow comet that only goes out past Jupiter rather than one that goes out of the solar system, we would have had to well exceed Voyager probes velocity in order to do so.

yeah about that.

For serious, this is actually big stuff.  Landing an intact probe on a frickin comet?  That is a billion well spent in my opinion.  Comets probably contain all sorts of interesting proto biological organic compounds and could be one of the sources for the molecules that life originated from.

1) Landing on a larger body requires a lot more delta-V. Bigger, more expensive mission.

2) Interesting stuff in Europa is under a LOT of ice, which we'd like to drill through. Bigger, more expensive mission.

3) If Europa does contain an environment that isn't hostile to Life As We Know It, we have to go to extraordinary lengths to make sure we don't introduce non-native life forms. More expensive mission.

Wait until we land something on Venus. All the news organizations are going to say that's a first as well.

It doesn't count because the Russians did it first?

That one was kind of low profile, wasn't it?

They had to rendezvous with a comet moving at 10 miles per second into the solar system.

That means they had to go out past it, swing around, and chase it down.

It took ten years and five trips around the sun.

AND WORKED.

It looks like this thing built up in layers like a hailstone, but has largely sublimated away.

I'd say this comet is really old and is slowly dying as it is no longer receiving any new ice.  So what changed?  Why was it building up for a while, but has now stopped?  Is it as old as the Solar System?

It also looks like there are the remains of impact craters, like footprints left as ice after soft snow melts.

It's just math.
