its why I hate travelling east on the M4.
All that fuel Im burning is being put into spinning the planet and Im still going backwards
Travelling west on the other hand is awesome as I get a lift from the planet and add a further 90mph to the total.

I love this stuff!
We only live for less than the blink of an eye, so miss most of it.

I like the idea of Nitrogen snow
you'd need a good pair of gloves to throw snowballs
I see the probe has reported back that the flypast was according to plan and that the data is on its way to earth as we type.
Brilliant.

I listened to a scientist on Radio 4 saying that New Horizons was already 2 million miles beyond Pluto. It has a little fuel remaining, enough to alter its trajectory by 2 degrees. They have another target in mind for flypast!

2 degrees at umpteen million miles is quite a variation. what did they have in mind?

I've been impatiently waiting for the Pluto images for the last few years, so very happy that we can fill a huge gap in our knowledge base about our solar system. Very little has been said about future targets, but they mention Kuiper Belt objects:Quoar, Eris, Makemake, Haumea or Sedna. It's hard to imagine that all of these are within the potential trajectory of New Horizons, which makes me think that the press release that mentions these hasn't given serious consideration to this comment. I think New Horizons is continuing to study Pluto and take more photos as it recedes into the distance. Once they've completed this, they will need to alter their course pretty quickly if they are going to reach a new target, so it's hard to imagine that this hasn't already been discussed and concluded.

Apparently there are very few craters on Pluto which implies that the surface is young which in turn implies that Pluto is geologically active which is a big surprise to the astronomers. A body as small as Pluto should have lost most of its internal heat from its formation and radioactivity, it's too far away from Neptune to experience tidal heating similar to some of the Jovian moons, so what is driving the activity?? Also it is quite mountainous which again implies recent geological activity, all very mysterious.

I would have thought the fact that Pluto is covered in ice would be enough to explain the lack of craters.

It could I suppose, but there does seem to be a variety of surface types around the imaged areas, the mountainous areas are particularly interesting.
https://www.nasa.gov/feature/frozen-plains-in-the-heart-of-pluto-s-heart https://www.nasa.gov/image-feature/the-icy-mountains-of-pluto in any case even if it was completely covered in ice of some kind, without an energy source to renew the surface relatively quickly craters would survive for quite a long time (or at least that's how our best theory goes at the moment) Nasa are estimating that the surfaces they have imaged are less than a hundred million years old, which in astronomical terms is almost brand spanking new.

I heard it on the TV yesterday, that the satellite will pass Pluto 1 minute and 20 seconds earlier than planned, when it was launched 10 years ago.
Looks like someone will be for the high Jump
. I was pretty impressed the arrival time was pretty well spot on, it is better than my arrival time to jobs !! whistlea

It has a lot of potential,
We could issue fracking licences on condition that they don,t export to earth. We could allow the GM guys to move there immediately, as long as they don,t carry any seeds and liquids with them. Then we could round it off with a dose of top bankers and politicians..errrr wait.. That could come back to bite us. There is the making of a right monster there,
