...but it's actually a magnetometer.
Is that even stable?
Maybe the nearest aerodynamicist can put me right, but wouldn't a weight on top and a weight on the bottom just mean that with the slightest disturbance the balloon rolls over until the two weights are more or less horizontal?
The only difficulty with that suggestion is making sure the plane doesn't tumble when it released, but it sounds relatively simple and would avoid too much spin damage on the way up.
I'm not sure.
These images are from a crater wall in the southern hemisphere pointing north in the summer, so it gets the full heat (hah) of the Martian summer. You'd expect that to produce a convection of air up over the rim of the crater - opposite to the pattern we're seeing here.
Also, when you put the graphic over a 3D terrain, you don't see any of the tell tale swirls that you normally associate with windblown debris, these lines are going straight downhill:

There's still a chance this could be liquid CO2 seeping out of the permafrost, it would be able to transport material downhill, but it wouldn't leave any tell-tale traces for the orbiter to pick up. But then, liquid CO2 is not normally found in these conditions.
I wonder if ESA can point their Mars Orbiter towards Newton crater any time soon.
The delicious Rebekah Brooks could have started a whole new 'Death to Paedos' petition had things not gone quite so spectacularly tits up for her and NI.
And a correction to the original article. The government has not promised that any petition which gets 100,000 signatories will be debated, they have said it 'may be debated'.
'Why is it that the Daily Mail is vociferous in support of penalties for certain crimes, but not so much for others (phone hacking)? '
You have to remember the same deranged moral compass that once had the Mail printing "Hurrah for the Blackshirts" has driven them on to the ideological rocks of the 1950s when everyone loved the Queen, there were no beastly foreigners around, everyone went to church and Europe could still be cut off by fog in the Channel.
There was a death penalty in the 1950s so we need it back. And only nice proper people had telephones back then and they'd never dream of listening to someone else's messages, so why the fuss now?
The plastic used by LEGO might not be capable of withstanding the heat, cold and radiation Juno is going to experience.
But I'm with you on wanting a set for myself (LEGO is far too good for children)
Does the plane need to be directly beneath the balloon? Instead couldn't you have a horizontal boom suspended from the balloon with the plane on one end and a counterweight on the other. Fire the plane up at an angle before the balloon bursts and it should clear the rest of the vehicle.
Either that or dump the balloon entirely and build a bigger rocket to create your very own Dynasoar. The rocket, of course, would have to fuelled with liquid hydrogen for maximum hilarity.
A Californian company is being sued by a Taiwanese company in the UK. Why exactly? For the air miles?
These cameras are just too small for me - and I don't have huge hands. I've got a Sony A700 which is a pretty old camera now, but it has a nice chunky design, generous grip and enough heft that the lens doesn't unbalance it unduly. I'm looking to replace it, but none of the cheaper dSLRs have the same sort of bulk.
But it looks like the powers that be have decided that if blobby shapes and saggy shoulders are good enough for the British physique, they're good enough for cameras.
Perhaps they'd like to start paying some tax on their income?
The USMC is only committing to 80 C aircraft which will result in them being more expensive than if the airframes had been made from the finest gold leaf hand-rolled on the thighs of Cuban women and then liberally sprinkled with sapphires. (I have no idea if this is how you go about making an aircraft by the way).
A dodgy bloke with a fag hanging from his lip comes round and clamps the rocket.
And the engines on this beast happen to be Russian, originally developed for the N1 super rocket of the 1960s.
The UK government encouraged companies to drill our side North Sea as quickly as they could with the result that the UK sector is the fastest oil producing region ever brought on stream. It is also now the one declining the fastest.
But for a while it was nice, all that money covered up the collapse of our manufacturing industry and paid for millions to be put on to long term benefits.
The Norwegians sensibly decided to manage their oil production through Statoil with the government pension pot taking the proceeds. The result being that not only does Norway still have lots of oil under the sea, but it is sitting on half a TRILLION dollars of assets that will keep on generating income when the wells run dry.
It was about the time BAE became heavily involved in selling weapons to the Americans that the US economy went tits up?
Where do you start?
The ISS is in an inclined orbit, geostationary requires one aligned with the equator. Changing inclination is a big job,
About half of the energy used to lift a kilo to geostationary orbit is used getting it into low orbit, the remainder is used in the transfer to the higher orbit. So take whatever energy its been to assemble the ISS and double it.
You'd then have to contend with the fact the ISS would lie outside the inner Van Allen Belt and would be exposed to more radiation and necessitate its crews being exposed to a healthy dose of whatever the Sun coughed up a few days ago.
And finally, we don't have any manned vessels that can get there.
I didn't know they reported on science and engineering for fear of upsetting their core demographic who are not quite ready for the breaking news that the Earth isn't flat, isn't six thousand years old, wasn't made by God and isn't centred around Sarah Palin.
And come without any undercarriage.
There are the atrocities of the Address Book and iCal whose interfaces are utterly broken by the insistence on copying real world alternatives.
Finder is still a dog. The left-hand pane listing foldings and drives is much harder to read now it has been stripped of all colour and contrast. And they still haven't fixed the basics of how data is presented in the Finder, the appearance of folder contents is still entirely random - will it be a list? a set of icons, a preview - who knows? That's the excitement / frustration of Mac OS.
And then there are the wretched animations that can't be switched off. Windows zooming out of nothing circa mid 1980s GEM and the drives me to distraction bunny-hop of a new Mail message window.
I wish Apple would get some real interface designers to work on their products rather than the kiddies who knocked up this monster.
If the Winklevosses keep this up much longer they will achieve the near impossible and turn Mark Zuckerberg into a sympathetic figure.
Guys, you got $65 million for having an idea and nothing more. I call that a pretty good payment. Now go off and play in your boats.
Why isn't Jeremy Hunt's best friend at BSkyB being tapped to help fund the service from his massive tax-free income?
Oh right, I forgot, Jeremy will need a job when his glittering ministerial career comes to an end.
As ITV's regional news areas get ever larger (The West now reaches from the Isles of Scilly to somewhere near Gloucester), to offset the cost of programming, Jeremy Hunt is trying to reverse the process by sucking money out of the BBC. He really is a useless spoonerism isn't he?
James Murdoch looks less plasticky in the photo than in real life.
With no Optimus Prime on hand, of course security was a joke
Get Brian Blessed to do the time - no telephone necessary.
It's usually Adobe Update that dies a horrible painful death rendering all my Adobe apps useless. It's nice to see they've made individual applications flaky this time round.
'How much has the average global temperature risen in the past two decades?'
Roughly 0.25 - 0.3 C since 1990.
Here's a good capsule summary with lots of plots:
You won't be too surprised to know that temperature records for both planet are patchy.
For Venus, well we really have a very primitive understanding of the Venusian atmosphere and how it circulates heat. It is about 100 times the mass of the Earth, so we do know it holds a huge amount of heat and changes very slowly. A Japanese probe which would have performed long term measurements of the atmosphere failed to enter Venusian orbit in 2010. At the moment there are no probes planned to do that task.
We have better records for Mars going back to Viking in the mid 1970s. On a planet wide scale the atmosphere has cooled noticeably since Viking which arrived at the end of a long period of planet-scaled dust storms. The storms served to warm the atmosphere and probably pushed temperature above trend.
There was a large retreat of the Southern Polar ice cap on Mars from 2001 to (IIRC) 2005, but this was not seen elsewhere on the planet. It is thought this was a regional effect caused by dark dust being carried from equatorial regions towards the pole. The dust absorbed heat and melted the ice. But even this is uncertain as the Southern Cap is very thin, some years it disappears entirely, others it persists.
'The fact is that there are 13 active volcanoes at this time, spewing out millions of tons of acknowledged greenhouse gases and dust and no one is tying this recent hot spell to that primary contributing factor.'
That'd be because none of the eruptions going on right now are large enough to have a significant warming or cooling effect I expect. I don't think there's been an eruption over VEI 5 for nearly 20 years and no overall increase in the number of eruptions in that period, so there doesn't even seem to be a correlation (let alone a causation) between them and recent global temperature trends.
Volcanoes 0.3 Gt CO2 pa. Humans 29 Gt CO2 pa.
Almost every climate story on the BBC involves Nigel Lawson being dragged up to claim he's not denying anthropogenic climate change, but...
The toxic old scrote is nearly as ignorant about science as he is about his forte of economics, but he appears to be given some credibility thanks being ennobled.
If the BBC could actually find some credible scientists who had problems with climate change science then it might not be quite so as infuriating.
But strangely, they seem to be few and far between.
We should rename the whole Plutonian system with Rupert at the centre orbited by James, Rebekah, Andy and Call Me Dave.
Since the planet is obviously named after the Disney character ;)
Going classical on astronomy's ass; perhaps Alecto, daughter of Pluto (the god, not the dog)?
Take the bottom model, DON'T put Windows 7 on it and you have a very nice Media PC.
This is a tempting upgrade to my G4 Mac Mini which has been a faithful EyeTV, VLC media box for some time now.
Now NotW can claim any undesirable email might have been tampered with.
I'd have thought that if anyone would be throwing punches today it would be Rebekah Brooks.
Thanks to the unique way in which the British government has always managed to bugger up our industries, in 1960 Fairey was forcibly merged with Westland along with Saunders-Roe and the helicopter division of Bristol Aeroplane.
Westland not only had their own helicopter designs but licensed technology from the Americans. The rotodyne was dead in their hands, but they held all the IP.
They're already immortal.
It's hard enough getting a decent signal on an iPhone without people leeching the signal.
Couldn't the message just be read as 'publish the results in as accessible way as possible, the interpretation will come later'?
The games however will be exactly the same as the current generation.
'Doesn't fall down' = antigravity.
Well it does in my Wile E Coyote Beginners Book of Physics Fun.
in a viking deathmatch against the almighty surströmming sandwich.
It's some crazy balloon, rocket spy thing.
They don't know who stole the plans, but the criminal mastermind goes by the name 'L'Ester' and is currently hiding at his secret volcano lair / donkey sanctuary deep in the Spanish mountains where he is designing a deep fat fried weapon of mass destruction.
A special operations unit made up from slightly shop-soiled supermodels is being formed to extradite him back to Guantanamo Bay where he will be chased by large spiders harvested from German supermarkets to the sound of Icelandic elf songs.
That lexicographic train has long since left the station.
The word 'hacking' now means any attempt to break into a computerised system no matter how it is done. It joins words like 'nice', 'garble', 'brave' and 'artificial' in having dramatically changed their meaning with time.
Give up, the battle is lost.
At least there won't be a nasty conflict of interest at Call Me Dave's next dinner party.
It'll be interesting to see where La Brooks pops up next.
In Britain we'd have used custard.
Possibly with a layer of jelly and sponge biscuits for the substrate. Soaked in cheap alcohol to mimic the natural state of a British brain.
Born in Wimbledon. He at least was once a British citizen. Anyone know if he ever got round to renouncing it?
