Virgin Galactic is probably one of the best known NewSpace companies with its sights set on catering to the public more than to the government. Now yes, I'm sure SpaceX wants to get into that game as well, but they're taking the government path, which may or may not be a good idea. That really depends on how the dominoes fall over the next few years, and whether or not SpaceX turns into Boeing or Lockheed...a government contractor. I lump Orbital Sciences into this mix as well, since for the most part they already are a government contractor in most respects.
But one must also remember that there are more players in the game than just the ones who currently grab the media spotlight. Armadillo Aerospace seems to have just locked down a deal with Space Adventures that hopes offer a sub-orbital ride at half the cost of Virgin Galactic. We shall see. I'm hopeful and curious to see how this unfolds.
It's hard to mention Armadillo without mentioning Masten Space Systems, who beat out Armadillo for the $1 million dollar prize in the 2009 Northrop Grumman Lunar Lander X PRIZE Challenge. Now Masten seems to be more focused on payloads than people right now, but I don't see them stopping short of the human launch goal.
Then you have Blue Origin, whose work seems to be more classified than the X-37b that was recently launched by the Air Force. Jeff Bezos seems to like keeping things hush hush, which could be a good idea. At least then when you test something and it fails, the media doesn't get all reactionary and all the pundits against NewSpace can't step up and spout off like idiots. It seems people forget that testing can and does result in failure, but the media just doesn't get that. Bunch of non-contributing zero non-scientists. :)
Now don't forget about XCOR, when back in December of 2009, the South Korean Space Center selected XCOR's Lynx for suborbital operation. They are moving hot and heavy on getting their craft up and running, and firing off thrill seeking people to the edge of space.
And to top things off (but this is by no means ALL of the companies, just those that I consider to be the biggest players) is Bigelow Aerospace. No, they aren't a launcher, but they will provide a destination. It would be kind of difficult to justify so many NewSpace launcher companies if they didn't have somewhere to go, and Bigelow is current the front runner in providing habitats in space, either orbiting in LEO, placed in GEO, stuck in a Lagrangian Point, or part of a Lunar Base infrastructure. Bigelow has a lot of options, especially once more of these NewSpace Heavy Lift options come online.
So as you can see, the game is in full swing. For the first time in human history, at least in my informed opinion, there is a light at the end of the tunnel that has restricted space travel to the select few as appointed by government. That light is NewSpace, and they are ramping up right before our eyes. What an exciting time we live in, because as far as I'm concerned, space exploration is a key variable in the equation for human advancement. Ad Astra was never a more valid term than today.
Let the games begin.
