NASA Outlines "Flagship" Technology Demonstrations 27
FleaPlus writes "As part of its new plans, NASA has outlined the initial series of large-scale 'flagship' technology demonstration (FTD) missions for developing and testing technologies needed for sustainable beyond-Earth exploration, complementing the smaller-scale ETDD missions outlined previously. The first four FTD missions (costing $400M-$1B each, about the cost of the recent Ares I-X suborbital rocket launch) are scheduled to launch between 2014 and 2016, demonstrating advanced in-space propulsion (next-generation ion propulsion and solar arrays), in-space propellant transfer and storage, a lightweight/inflatable mission module at the ISS (which will also test closed-loop life support), and an inflatable aeroshell for aerocapture at Mars. A multi-purpose robotic rendezvous and docking vehicle will also be developed to support these missions."

I don't see what the problem is here.
So they shuttle us up and then we blast off to Mars while they're still stuck in LEO or at best Lunar landings.

Well, they are the ones with few decades of experience with operating a manned spacecraft which is essentially capable of beyond-LEO operation (and has done so few times). Plus also assembly via autonomous docking and in-orbit refueling.

I totally agree with new approaches and new development. But I want to mention two things you might not be aware of.
Bigelow Aerospace has flown 2 inflatable Habitats since 2006. The foam they are made of was originally developed for the ISS, and tech transferred to a private company to develop it further.

http://en.wikipedia.org/wiki/TransHab [wikipedia.org]
Heck their Sundancer manned habitat might BE the tech demonstrator for inflatable habitats.
The VASIMR 200kw electric propulsion system tested on the ISS, can only run for 10 minutes on batteries that have to trickle charge because the ISS only has 110kw of solar power available.
So while these things aren't man rated yet, I can see where the tech demonstrators for these would be quick to put together with little 'new' development time.

Adding to what Tekfactory said, ISS regularly refuels in orbit. Heck, the docking interface of Progress has inbuilt means to transfer fuel.

When it comes to space flight, the public is awfully ignorant. Perhaps we should stop worrying about public opinion so damned much and start doing real work. The astronauts and other people in the programs who put their lives on the line for it understand what the risks are and what they are doing. This is too important to be left to public opinion.
The irony here is that private space companies are more likely to succeed because they don't have to answer to the public as much as government

Oh, and Bigelow's design is based on something done for NASA back in the '90's, I think.
In other words, this is hardly ground-breaking new technology, but a rehashing of tech NASA was ordered to drop back when it turned

Two things: the theme of NASA's announcement was that they were investing in new breakthrough technologies. Fifteen year old tech that NASA was working on in the '90's is hardly "new", much less "breakthrough".

What NASA should be looking at are things that are, well, new. Unproven. Requiring further development. Tried and true not so much. Investing in development of something that's already completed its development doesn't match up with that.
In general, NASA's announcement of its new direction seems to be "we're dredging up a bunch of things that we think will be pretty easy (in one case, because it's already operational) so it looks like we're accomplishing something...."
See my other comment. This announcement is only for testing relatively mature technologies in space, while other programs (e.g. NIAC, SBIR) are for more novel technologies:

They couldn't have really developed all of this since the announcement of the cancellation of the Constellation program.
Seems more likely they just grabbed a bunch of already developed tech and slammed it together.
On the plus side, the fact that they're actually focusing on this tech which I heard they were developing years years ago, at least for the ion propulsion and inflatable structures, shows that NASA is finalyl getting off their feet and working on them.

Keep in mind all of these technologies have been on NASA's back-burner for a while (and most/all had their funding cut when Ares/Constellation started going over-budget). These "Flagship Technology Demonstrators" are also specifically targeted towards technologies which are already of mid-level maturity but have never been brought to the point that they could be tested in space before. There's a figure on page 2 of this document which does a pretty good job of explaining things:

I imagine they are relying on the private companies who have been developing this technology - such as Bigelow with inflatable habitats, and the numerous work on solar electric propulsion, etc. After all, it has already been stated that NASA will be relying on private companies a lot more.

One of the projects is for on-orbit storage and transfer of cryogenic propellants. I wonder if "cryogenic" has the traditional NASA meaning of "liquid hydrogen" or if it refers to easier-to-handle substances like LOX or liquid methane.
