ESA Complete Spaceplane Test Flight; IXV Safely Returns To Earth 56
hypnosec writes The European Space Agency has successfully completed the first test flight of its Intermediate eXperimental Vehicle (IXV), as planned, wherein it saw the wingless spaceplane land in one piece in the Pacific Ocean. A Vega VV04 rocket took the IXV to an altitude of 340 km, from which it separated and continued up to 412 km. Reentering from this suborbital path, it recorded a vast amount of data from more than 300 advanced and conventional sensors. According to ESA the spaceplane few east around the globe during its descent and finally landed safely in the the Pacific Ocean west of the Galapagos Islands at about 15:20 GMT.

perhaps a bit of competition will bode well for space exploration development.
It's probably not the incentive military superiority or corporate profit would be, but it's still promising.

People in our intelligence agencies continue to fund our development of space. They're not delusional; they have direct experience. They assume that their counterparts are competent; if other intelligence agencies aren't; they're negligent. All of those countries mentioned, China, India, the ESA states individually and collectively, and the US have real enemies and real intelligence needs.

For the most part I disagree. Russia's nuclear program DID become the second most capable (some even say the most capable) in the world. Not necessarily technologically, but definitely in numbers. It was therefore a real and credible threat.
Kruschev probably meant his bluster to be more of an economic threat that technology-military, but I think we can all agree that's all THAT was: bluster. Though even he might not have realized it at the time. Their real problem was that they could not keep up economic

Don't forget Japan which has delivered cargoes to the ISS using their home-grown launcher. They also launched a spacecraft, Hayabusa deep into the Solar system to rendezvous with a comet and return particle samples back to earth. The Hayabusa-II followup mission launched in December 2014 and it plans to return samples of an asteroid as well as landing three small hopping "rovers" on it for close-up study of the surface.

Well NASA is paying for the things, there is already a contract in place. I suppose nothing is stopping the ESA from buying SpaceX missions.
But I expect that any Europeans that fly to the ISS on Dragon would be doing so as a part of a NASA mission launched from Cape Canaveral. Just like everyone currently flying to the ISS on Soyuz is doing so as a part of a Roscosmos launch.
I highly doubt that the ESA would purchase Falcon/Dragon to fly from their own facility. This is the entire reason why IXV is a thing.

Nonsense. Certain people realized that NASA+government bureaucracy was failing the space program and the people, repeatedly, and that we sorely needed alternatives.
If that were not so, we would not have needed Russian boosters for our own rockets or Russian launches to supply ISS, while the private companies ramped up. But we did indeed need them, without which our manned space program would indeed have failed, pretty much completely.

NASA was failing hard by insisting on using the Shuttle to launch everything. The Russians had really good LOX/Kerosene staged combustion rocket engine technology so it was a good idea to get the engines. The problems started when the US contractors cheapened out and decided not to start US manufacturing of the engines as originally planned. The Russians transferred all the required technical documentation and provided a production license to do it.

I don't dispute any of this. My point was that lack of planning and foresight on the part of the existing NASA bureaucracy was what led to this whole situation.
Any idiot should know that for any strategically essential technology, you should have not just a robust, maintainable program, but also a ready backup. NASA had neither.
I'm not placing the blame on them solely. Short-sighted politicians were definitely a part of the problem too.

The US has several manned programs in "testing". There is NASA's own Orion [wikipedia.org], which has flown unmanned, and should be ready to carry people in about 6 years. Boeing and Bigelow have the CST-100 [wikipedia.org], which has not flown yet - but is scheduled to be crewed in late 2017. Furthest along is probably SpaceX, with their Dragon V2 [wikipedia.org], scheduled to be crewed in early 2017. The last two options are particularly exciting, since they promise to cut the cost of getting an astronaut to the space station by up to 2/3 compared to a Soyuz launch.
We are still recovering from the lack of development that occurred when NASA was using every dime to fly the space shuttle and construct the space station.

Sorry, I have to correct you there. Unless Russia has been publishing their internal costs and markup of their launches, we only know the launch price of the Soyuz. Unless they are very foolish, the cost is a secret.

I mean, that IS the basic idea. But it's just a bit too simplistic.
If your gravitational body has an atmosphere, the lowest point has to be high enough to not create significant drag. Or else sooner or later it very definitely WILL crash.

And of course, a key for simplifying reentry is "no bigger or heavier than absolutely necessary". Even the X-38 would have fit in side the

The "plane" in "airplane" or "spaceplane" refers to the shape of the lifting body (i.e. the wing, technically the bottom of the wing). Just like your hand forms part of a geometric plane when outside that car window, so does the bottom of the wing form part of a geometric plane. It is this plane which forces the air down, hence the term "air-plane".
Since this design generates lift by pushing the air down, it is a "something-plane".
