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.

Ah, finally a reason why they took Play School off the air. Betting on which window it would be today...
Mind you, it got harder to get BBC Presentation to take the bets when they realised VT were putting cryptic notes on the paperwork during the tech review...

"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.
Re: COTS is about commercial competition...
http://spaceflightnow.com/tracking/ is a handy list and generally stays current. That lists a Falcon launch for the 3rd, but no sign of a webcast on the SpaceX site yet...
As I remember from discussions years ago, yes. The problem back then was there was nothing on The Shelf, Cheap or not, to take Off. The acronym stuck but the words changed...
Postponed, not aborted
The Dec 19 launch was postponed due to the ISS cooling problem so the focus could be on the repair spacewalks. It was the demo launch back in April that was aborted when a cable detatched early.
The actual legislation probably won't specify the connector, just requiring a standard one is used and leaving the choice to be determined by whatever the EU equivalent of a Ministerial Order is.
That's OK then, the SLS and Orion *are* subsidies to corporations...
Re: How about a little perspective here?
"But right now both FH and SLS are paper rockets"
Actually the stages for the first Falcon Heavy are mostly assembled. The engine clusters ought to be test fired on the static stand in Texas early in the new year with an actual launch from Vandenberg lightly pencilled in for around April, though that will probably slip.

Re: 80,000km > 35,786km
Missed the edit window...
The fuel saving is mostly in the plane change manouevre, the higher that is done the less fuel it takes. A launch from Kourou will generally go straight to GEO altitude as it's almost on the Equator anyway. From Cape Canaveral they need to lose 28.5 degrees of inclination so it takes less fuel to go higher, change plane and drop back, and from Baikonour you need to change by about 56 degrees which makes the Lunar fly-by option tempting.
Re: Launch Window?
Partly sun angle in the transfer bit of the orbit, and partly how long the launch team have been working. You do not want a tired ground control team, or have to try and manage a shift change part way through.
Re: 80,000km > 35,786km
It actually takes less fuel that way, although it needs two engine burns to get to the final orbit rather than one. A burn at apogee (the 80,000km point) raises the perigee to GEO altitude, then half an orbit later a second burn drops the apogee and circularises the orbit.
There have been trajectories involving a trip round the moon calculated, although so far the only taker was a Russian launch that had a stage restart failure and used some of its manouvering fuel to do the loop and circularisation. It wasn't carrying enough fuel for a direct insertion. Satellite operators are very conservative and no-one wants to be the first to use a lunar fly-by for real, they all want someone else to demonstrate it works.
"The Five-ish Doctors" that followed on the Red Button (and is no doubt available via other channels by now) is well worth a watch too, and makes me think a lot of the 'news' in the lead up was dis-information...
Re: Let SpaceX launch it!
It's just inside the capability of a Falcon 9 v1.1. Not sure where you're getting the 6,500kg figure from but the SpaceX site gives around 4,850 to GTO for a non-R and you generally get two thirds of that to Mars, and two thirds again for the F9R.
If "Dalek" had been called something like "Last of his kind" (by then we knew there were no other Timelords) and not had the big reveal trailed heavily beforehand, you could have spotted the moment the Dalek spoke its first words on a seismograph as everybody dived over the back of the sofa.
"The Girl In The Fireplace" was helped by David Tennant and Sophia Myles being involved at the time.
In "Human Nature/Family of Blood" there's a nice line where the human Doctor gives his parents names as Sidney and Verity.
But "Blink" is pretty much the perfect time travel story, and bears repeated rewatching for the small details like where Sally Sparrow walks between an Angel and the camera, and the Angel changes position in the fraction of a second while it can't be seen.
In the days of models they were quite often filmed upside down. Turns out the human eye is quite good at spotting strings above a model spacecraft wooshing across the screen, but not when the shot has been inverted so the string appears to be at the bottom.
Re: Cornflakes and beer
Of course not. Breakfast is when the days bottle of scotch gets opened...
Sarah Jane mentioned it to the David Tennant incarnation when they met up in "School Reunion". Her last words at the end of "The Hand of Fear" had been something like "I bet it's not even Croydon".
Re: Poverty and Space Shots
India needs a space programme to help improve conditions in the country. They were one of the first widespread users of satellite direct broadcast TV and make a lot of use of space based communications, weather and earth resources assets. The money spent on any form of space programme doesn't just evaporate, and it is far better for it to be spent via local institutes and manufacturers than for it to be sent abroad to buy services from foreign agencies.
Dropping in an occasional pure research and prestige mission is a very small increment to the overall budget, and almost certainly helps retain the talent required to keep building the applications programmes in the future.

Hmmm, security patrols?
In a former workplace the overnight security guards were supposed to take a walk round the building every so often. Dotted round the place were some sort of tags, and when they did their rounds they carried a reader with them that recorded the time each tag was visited. NFC could replace the daily or weekly download with realtime, and result in a call ("Do you need an alarm clock or assistance?") or visit in case of missed.
Also geo-caching without suspicious looking boxes in public areas.
Maplin include the VAT, RapidNFC don't, so it's nearer a fourpence difference when you account for that.
Re: Ok what have I missed
Simples. You've used two different time units. 8600 km per *hour* and 9.82 m per *second*^2. You did the multiplying by 1000 to change the km to m, but skipped the 3600 to change seconds to hours or vice versa.

Re: Can some boffin explain how it works
It's a combination of light pressure and solar wind acting on the various stuff evaporating from the comet. The small gas and dust particles are affected more than the main body of the comet so start lagging behind.
When a comet picks up a large sideways component to its velocity you quite often get multiple tails as different size gas molecules and dust particles are sorted by the acceleration they pick up from the light.

And the quick sample I've just looked at all show the classic signs of FR, soft, vignetting around the edge and, as someone mentioned in another comment, things crawling across the screen.
A pedantic ex-BBC VT engineer points out...
In 1953 the BBC was still five years away from having any kind of magnetic video recorder. VERA arrived in 1958 and used spools of wire. Most programmes were done live, and a film recording (Cine camera pointing at a monitor with a long persistence phosphor) would only be made if there was a chance of an overseas sale.
One advantage of hypergolic fuels is that they self ignite as soon as they mix so you don't get much of an explosion. The American Titan II used the same sort of fuel which led to the Gemini launch escape system being ejector seats instead of the solid rockets used on Mercury and Apollo.
Re: There are other issues
"the concern as to whether the pad would survive holding down an SRB for two minutes"
Ooh! An easy one! It wouldn't. Once the SRB lit it was going somewhere, the question was how much else of the stack went with it. If both lit at the same time then everything was fine, if only one lit then the external tank was going to rip in half. The hold down bolts were triggered by the same signal that fired the SRBs anyway.
There were a couple of cases where the explosive nuts on hold down bolts failed to fire. Either the bolt would stretch and snap (it was actually designed to do that) or the whole thing would pull through the skirt of the SRB.
