I believe they fly it for about half the launches to the ISS (the other half fly the opposite angle southward). The 51.6 degree orbit carries it pretty close to the angle of the coastline.
Actually, all launches to ISS from Kennedy Space Center follow that course. For some reason, Cuba doesn't like American stuff in their airspace, so the descending node (southward) launch window is never used.
I wonder how how much of whatever the New Horizons probe finds during it's Pluto fly-by in 2015 will already be known by then, when you take the ever improving optics and other remote viewing technology into account.
The departure date depends primarily of favourable launch windows (proper planetary alignment that allows for low-energy transfers). It's not because it takes ten years to plan and put together the mission. Sure, we could launch the thing tomorrow (or as soon as we put it together), but it'd take several times more energy to reach it's destination, which means more powerful rockets, if a powerful enough one exists. Keep in mind that most of the modern interplanetary probes are launched with the same rockets that launch commercial satellites to geostationary orbits, which is quite a few orders of magnitude closer than Jupiter.
Wow, that was a lot smaller than I'd imagined. This kind of demonstration really makes me appreciate the work the cosmo/astronauts are doing, stuck in there for months, having to put up with cramped space, the noise of life support systems, clutter everywhere and motion sickness inducing orientation with modules left,right,up and down, not to mention next to zero privacy.
I still wouldn't mind a free ticket for the one week ride the space tourists (pardon, "private spaceflight participants") get, though.
I'm all for teaching evolution but would someone please explain to me what the issue was with teaching the strengths and weaknesses?
If science teaches us anything it is that we should always continue to question and refine our studies, not idly stand by and accept them as fact.
Well that's the problem, most of the intelligent design people don't want you to know its strengths and weaknesses beyond what they perceive the Bible to say about it. They couldn't care less about scientific principles when it comes to issues of faith.
In the case of the USA, the location of the Kennedy Space Centre (Florida's east coast) was also chosen because it puts most of the spacecraft's ascent trajectory across the Atlantic ocean, a safe distance from any inhabited areas. Unfortunately, the Chinese don't mind vaporising a village or two in case of a launch mishap.
The net energy gain and benefit depends on what kind of orbit you're launching into - for example, a launch into an equatorial orbit (as is required for geosynchronous satellites) can only be performed from the equator - barring expensive plane change burns in orbit, while it actually makes more sense to launch into polar orbit from locations away from the equator, since the Earth's spin is irrelevant as the intended orbit is perpendicular to the spin direction.
Launching from a higher altitude is largely irrelevant energy-wise, since the majority of the energy wasted on orbital ascent is spent acquiring horizontal orbital velocity (~8km/s), not gaining altitude. While the atmosphere is thinner at 9 kilometres altitude, the logistics required to haul a launch centre atop mt. Everest hardly pay off the energy saved.

It would also require that the large majority of the users/contributers to the system actually do so with good intentions and aren't trying to deliberately mislead the traffic behind them. That may be the case, but the article makes it sound like it's pretty easy for a single person to game the system.

The DS needs more games period. Any improvement in this area is welcome.

Wireless power transmission is wasteful.
Level the Nevada desert and cover it with solar cells.
London needs help on their series of tubes.
They could always replace them with a big truck you can just dump people on...
It could come with a secondary "safe mode" that pulls back into a compact wheelchair when the batteries run out.

Until we arrive at an overtly panoptic government, I wouldn't mind volunteering for my data to be shared if it helps.
I can certainly see this being used to help the traffic control police - aka revenue generator.
Because the secret handshake isn't obvious enough?
Oh, wait, forget I said that. There is no secret handshake.
