The electromagnetic force that is.
Why would you bother with atmospheric drag, just pay out a cable and use electromagnetic drag instead. Oh wait they can do that already...
Terminator Tether - EDT Solution To Space Debris
Well a lot of the cost is the inefficient nature of the Shuttle launch system. Every launch of the shuttle puts 110 tonnes in orbit, but around 90% of that is the shuttle itself. Rather than 10s of launches the ISS could have been put up with a handful of NLS launches freeing the shuttle for what it does best, servicing a space station and bringing samples back.
The Environmental Control and Life Support System (ECLSS) planned for the ISS will use recycled water and split it into Oxygen and Hydrogen. The Oxygen is used to support the crew while the hydrogen is dumped. A VASIMR might be able to use this hydrogen to reboost the station, reducing the need for ISS resupply with toxic propellants.
Ares 1-X has NO commonality with the currently proposed Ares 1.
Ares 1-X uses a 4 segment booster while Ares 1 will used a 5 (or more) segment booster.
Ares 1-X has a dummy upper stage etc.
I'm sure Ares 1-X will look good but there is no way you could call it an Ares 1 vehicle beyond it looking vaguely similar. It's a Space Shuttle solid rocket motor with a body kit.
The first mission of the new plan will likely have more boots on the surface EVA time than the entire Apollo program.
To say that Ares is just replicated Apollo is like saying you've visited the UK after transferring flights at Heathrow.
No the Alpha Magnetic Spectrometer is not going to fly, even though congress has offered the money for another flight in 2010. Nasa management doesn't seem interested.
I think the only hope for the AMS is in a change of NASA management in 2009, that is if the ability to fly another STS mission hasn't already been lost by then, though I expect it would have.
The first experimental GPS sat was launched in 1978
The first fuel cell was built in 1843
The technology has been around to do this for a while now, the reason for the long time lines is lack of money not lack of courage. The lack of money isn't necessarily a bad thing it makes the whole program a much more sustainable effort.
Well seeing as the point of sending people to the moon is to figure out how to get humans to survive off planet just sending robots seems rather pointless. There is nothing to stop you sending robots as well in fact sending both is probably far more productive than either alone as then enhance each others strengths.
According to a study of Neanderthal mtDNA by Svante Pääbo et al Neanderthals and modern humans had a common ancestor 500 thousand years ago, this means Neanderthals and modern humans didn't interbreed.

The parasail behaves very differently to a normal triangular sail or even a jenica. You move the parasail constantly through the air in a figure of eight to generate power. Also these ships are likely to follow the trade winds where the wind normally comes from the stern, therefore attaching the sail to the bow won't be a problem as most of the time the ship would be traveling on a broad reach or run.
"Along with statistics that show more powerful cars are less likly to get into accidents."
That because there are less of them or their not used as much. IE how many five wheel cars crashed last year?
According to the video it seems the first stage thermal blanket added to reduce LOX boil-off, the casue of the first two launch delays, didn't release proberly. In all likleyhood it was this that cause the roll and loss of control.
Live video was shown of the vehicle's ascent from an onboard downward pointing camera. Within a few seconds the feed started to become intermittent.
The small amount of imagery available showed a bright yellow glow protruding away from the normal exhaust pattern, as the rocket began to roll violently.
The ascent profile also appeared to be more horizontal than what would be expected for that stage of the ascent.
The video then cut out completely - with SpaceX confirming the rocket had been lost just moments later. - http://www.nasaspaceflight.com/content/?id=4394

Same thing, from what the summary says it sounds like they used the Cambridge Weight Plan which IS a low carb diet. https://www.cambridgeweightpla...

Think that is amazing, check out this map of undersea cables, from 1901!
YES! :)

You can travel up wind using a parasail, same as you can travel upwind with a bermuda rig. It's just not worth it if you have an engine.

Also these ships are likely to follow the trade winds where the wind normally comes from the stern, therefore attaching the sail to the bow won't be a problem as most of the time the ship would be traveling on a broad reach or run.
While I agree the US does fund alot of space science so does Europe, ESA funded about 15% of the Hubble. Long may the co-operation continue.

It's the stainless steel construction ;)
"ESA to Send Spacecraft to Venus"? They already did, Venus Express launched on 2006-11-09, it arives at Veuns on Tuesday.

I think the RSO terminated the thrust due to excessive rolling (there is no 'self destruct' on the faclon 1, then engin just awitches off)
