Re: Information please
Not for a while, best displays seem to be a year or two after perihelion and at the moment the comet is around aphelion. Last perihelion was 1998 so watch the skies 2031-2034ish...
As it says, bits of the comet with a 747 to give an idea of scale.
Makes sense from the images. If you look at the picture of the incident, eg on http://www.space-travel.com/reports/Probe_of_US_spaceship_crash_may_take_year_999.html and now treat SS2 as being upside down and backwards you've got the engine still firing at the top and the tail booms deployed either side. The feathered configuration is supposed to hold the nose up during re-entry so the base of the ship is maximising the cross section, deploying while the engine is running is lilely to send you into a very tight loop the loop.
Re: Why do the play-by-play announces ALWAYS downplay these?
Because the console operators usually only have screenfuls of numbers to look at, all they see is that the information they're getting is very odd or has stopped.
The SpaceX one was a first stage problem. They lost an engine on the way up so the other 8 ran longer, that left everything in slightly the wrong position so they couldn't do the second burn after the Dragon separated to get the Orbcomm secondary payload in the right orbit.
First stage engine problems aren't unusual, but they frequently show up before the rocket has left the ground so everything gets shut down and can be fixed.
There was a Progress launch due around ten past seven this morning. They might just have had time to get a few copies of said Newspaper Shaped Object on board.
Re: Russian conspiracy?
Not just the same as, they're actual engines built for the N1 before it was cancelled that have been in storage ever since. Another one exploded on the test stand recently.
Re: Probably a question for http://what-if.xkcd.com/
They don't push at all, just move it out and let go. The attitude at release is carefully worked out so the Dragon can fire thrusters without the plumes hitting the station.
I've been trying to find out if it does Qi (or any other form of wireless) charging. It's so nice with my Mk II Nexus 7 to just drop it on the pad instead of having to fiddle with micro-USB late at night.

Although for the ISS you'd probably be better off 3d printing a small crossbow. You could print the bolts for it too and there would be less chance of putting a hole in a module when it goes off accidentally in the struggle.
Shirley a double brace is a mere four rather than eight?

Next time you see a Lanc, remember its wingspan is a gnats over 100ft so when flying a dam buster attack run the height above water was about the same as the distance from one wingtip to the inboard engine the other side...
Re: Possessing an image likely to cause injury
It's the act of creating the image potentially causing injury I believe. Posession of the image counts as encouragement to make more.
Re: Questions for rocket scientists:
The Dawn spacecraft, currently in transit twixt Vesta and Ceres has two 18 sq. metre solar arrays which combined produce 10kW at 1AU and 1300W 3AU out in the Asteroid Belt. Inverse square and that's about what you'd need for 2.5kW at Mars distance.
Earth to Mars takes around 9 or 10 months on the cheapest ballistic transfer orbit depending on exactly when in the launch window they're sent, the Indian and Nasa probes launched back in November are due to arrive this September. Even quite modest continuous thrust can cut that by a lot, but it also greatly extends the launch window so you don't need to wait until the planets are exactly aligned and can launch at almost any time.
Re: "(aka kaboom)"
Although now a later tweet says "Detailed review of rocket telemetry needed to tell if due to initial splashdown or subsequent tip over and body slam" so maybe not so much KaBoom! as Tim-berrrrr!
Rotors v. Rockets
For an actual Mars landing you'd use Rockets instead of Rotors. ElReg SPB already has experience of things like ArduPilot which can handle a wide variety of motors in its quadcopter guise, rotors to rockets might be a bit beyond the usual parameters that need tweaking but not hugely so. They can also use a wide variety of positioning systems, get a fix from existing Mars probes on the way in and an inertial system will get you close enough to your desired boulder-strewn landing spot.
At least it's not a serious Mallard'y.
It's a nice day, I won't need my coat...
Car mechanics. They know *where* to hit a vehicle to make it work again, they just need a range of suitable hitting implements to suit the fault.
If you have a look at the animation there's usually a cover over the connector panel. You need to have a lot of connections to the trunk (power from the solar cells, data connections, etc) as well as to the rocket telemetry on launch. Easier to go round the side of the heatshield than try and run the wires through it. If you look at a picture of the Apollo CSM (eg http://en.wikipedia.org/wiki/File:Apollo_CSM_lunar_orbit.jpg ) you'll see exactly the same setup with the cover over the cables and panel being the lump at the bottom of that picture.
No, insUlation. The solar panels are supposed to fold back over the body during the night to help keep the internals warm enough. The mechanical problem appears to have been that one of them didn't.
As mentioned in the bit about Zinnwaldite, spoil heaps can be useful sources of stuff that was originally uneconomic to extract. Devon Great Consols mine was once the biggest copper producer in the world, then the largest arsenic (The extraction methods for the arsenic can make you shudder) producer. Since the mines closed at the start of the 20th century the spoil has been reworked for Tin, Tungsten, more Copper and more Arsenic as prices and technologies changed.
Re: It looks suspiciously like an AE-35 unit
Actually the computers do like having atmosphere, it's a real bugger keeping them cool without. The ones outside usually have to be hooked in to the ammonia cooling system which also needs regular EVA maintenance.
And Ariadne gets to keep the banner after the flight?
First stage status posted around 22:00 BST on their webcast "Last known state for rocket boost stage is 360 m/s, Mach 1.1, 8.5 km altitude and roll rate close to zero (very important!)" and a few minutes earlier "Falcon reentry burn also good. Waiting for landing data from tracking plane."
It's OK. They'll be using a version old enough to be unaffected...
The Norwegians have previous...
"The film that is so funny that it was banned in Norway!"
Which was of course Life of Brian...
Previous out of the ecliptic missions (eg Ulysses) have used Jupiter to do the perpendicular bit. You aim your craft to go over one of Jupiters poles instead of round its equator. Cassini has used Titan in the same way to swap between orbits in the ring-plane of Sautrn and inclined orbits.
Shades of the Cambridge guided busway. When it started there were five bus companies going to use it, but by the time it opened that had reduced to two via mergers and takeovers. Some of the documents had apparently been updated by search and replace as it was eventually announced that "Whippet, Stagecoach and Whippet" would be running services from day one...
Re: Must be a techie...
The original phrasing used though implied it was eight track carts, not reel to reel on which the number of tracks would have been invisible to a journo of Mr Robinsons calibre. He would (probably) however have recognised the more common eight track due to their widespread use in radio studios where, with the tape being an endless loop, they were favoured for not needing to be rewound after every use. And I first encountered them professionally 35 years ago...
Re: Must be a techie...
"At least Robinson got the number of reels on the tape machine correct."
No he didn't. Eight track used an endless loop and only one reel...
Re: Pliers cause pain
The maintenance department at the ITV station I was employed by contemplated getting a calibrated mat so they could measure EHT voltage by how far their summer student jumped every time he got a shock...
Re: 2014 DX110
Usually means that after it was discovered and its orbit worked out, they've gone back to old photographs of the relevant area of sky and found a previously overlooked trace.
A law firm with the name Selachii?
I'd be inclined to use them just for their sense of humour.
It's enough to pay for a team of around a dozen people for 7 or 8 years to work out the detail of what will be needed and what instruments can be fitted in to various launch configurations. Once they've got the plans worked out it will start needing real money to build and launch the spacecraft.

"An upvote to the commentard who can work out the riddle of the last one"
Probably related to the occasion at an ITV station where I was employed when the emergency standby generator fired up and cut in around 3pm due to loss of external power, then promptly shut down due to excessive load taking the region off the air.
Later that afternoon a missive went round suggesting it would be detrimental to peoples career prospects if kettles were ever found plugged in to the technical mains again...

Re: A lot of risk was taken for the Moon landings
The pilot of the lifting body that featured in the Six Million Dollar Man titles actually walked away from that crash, although he subsequently lost an eye due to an infection picked up in hospital.
The Apollo 11 landing had around fifty seconds of fuel remaining at touchdown, if it got down to 30 seconds then an abort was required as the remaining fuel was needed to get enough altitude for a safe stage separation and ascent engine start. They were 20 seconds to that point, not to dry tanks, and as has been mentioned already the stages did not share fuel or engines.
Re: This was a resurrection of a failed proposal...
Antares is unlikely to get man-rating in its current form as the second stage is a solid rocket. Solids running in parallel with a liquid first stage are allowed, especially if the designer is NASA, as a capsule LES can get the crew away in an abort but there's no sensible way to get off a malfunctioning solid second stage.
The first stage is not hugely different to the Ukrainian Zenit, hardly surprising as it is designed and partly built by the same company under contract.
