Isn't the HL-20 design based on the soviet BOR design for the Spira space plane?

Is there any indication if the Spiras movable wings have been retained?

I'll have to pass on that, but I'm pretty sure the HL-20 didnt...and they seem to be saying they are sticking with that design concept.

So why would NASA wish t go with a more expensive, lower capacity vehicle over this one?

NASA is looking for a multi-purpose structure, which can go to the ISS, the Moon and Mars etc. They don't want several different ships for several different missions.

How does that one land? Like an orbiter or with paracutes?

For control and cross range capability this seems like a no brainer for NASA to use for transportation in LEO.

Great news. The concept already has some professional development and testing behind it, both by the Russians and Amerians. Hopefully this will be enough to attract investors. Personally it was my favourite choice for a CEV before the recent announcment.

Some Links:

http://www.astronautix.com/craft/hl20.htm

Also: http://www.mathworks.com/access/helpdesk/help/toolbox/aeroblks/aero_s12.html

Maybe there will be a return at last on all the past investment by NASA and the US taxpayer.

Furthermore, I think this idea (HL20) was just too good to waste. Development is probably at the same stage as the Russian Klipper. There's nothing like a bit of competition ;)

Great days ahead...hopefully

Excellent news, we should all get behind this and support what SpaceDev want to do. Think of the potential money saved from the CLV project. There's your ticket to get the ISS completed and the CEV off to the Moon by 2018.

This vehicle has nothing to do with exploring. However I like it. I keeps space tourism happy and if used for crew transport to the ISS then it might help NASA shortcut some of the plans to get more advanced towards the 2018 target. Jury is out, but I'm listening.

SpaceDev have a good relationship with NASA Ames and I'm sure they'll get a fair shot at showing what they can do with this vechicle. They do need the funding first of all.

I'm impressed by the way they are looking to use previously designed hardware. Thanks to the images above this post, you can see how this is a good concept.

I love the Energiya/Buran type side-mount stack.

Over at the www.buran.ru website there was an enormous sidemount lifting body. The topmount "Glushkoyot" MTKVA was larger but needed to be top-mounted on Vulkan. This is an AMROC mini-Buran position with a bit of the SLI look---what with the lifting body in front of a long tube--rather like Spiral 50/50.

But I thought this Dream Chaser was to be a scaled up X-34, though:

Wings too heavy?

The more ther merrier I say!

If there really is a market for space tourism, then some competition can only drive the price down. SpaceX, t-Space, Space Dev, CEV, Klipper - I like em all :)

This is highly unlikely to get an FAA licence for commercial manned flight, as a side-mounted orbiter is perceived to be an inherently unsafe design.

Only because of foam and debris. This one doesn't use super cold fuel so it doesn't have that problem that yousay would be feared.

And it's it only for the first part of the flight, then it becomes a single stick stage?

Looks like the booster section is just for the ride the SRBs would be for the STS. And given the article says the ice and foam concerns are no more than that previous argument doesn't seem to stand up.

Side mount keeps your connectors and your rocket motors separated by a good bit, at least. Ice should not be a problem.

The less said about Forrest Gumps t/Space nonsense the better.

It looks like the USAF will be providing some of the investment for the development of the boosters: http://www.spacedaily.com/news/rocketscience-05zzw.html

SpaceDev Awarded Hybrid Rocket Motor Contract
Nov 18, 2005
SpaceDev has been awarded a $2.7 million contract by the Air Force to begin work on a large hybrid rocket motor.

SpaceDev is to design, develop and test a small common booster capable of producing about 100,000 pounds of thrust, almost nine times that of the SpaceDev rocket motor technology used in Paul Allen's SpaceShipOne which won the $10 million Ansari X Prize last year. Test firings of the prototype rocket motor are to begin next year.

........."We also believe that this technology will be another significant step toward developing our own reliable, low cost, safe cargo and crew vehicles, like our proposed SpaceDev Dream Chaser orbital human space transportation vehicle. We believe the technology can also be adapted for use alone as a sounding rocket or target in our proposed SpaceDev Streaker small launch vehicle family."

Ice and foam are not the only concerns with a side-mounting. The fundamental problem is that if anything happens to the booster, the manned compartment is alongside, rather than above. This increases the risk that the manned compartment will be damaged, and decreases the efficitiveness, and therefore survivability, of any measures to get the crew safely away. Ice and foam did not cause the loss of Challenger.

Given that NASA is trumpeting the CEV at the top of the stick as one of the main reasons for the decreased risk it quotes, any bureaucrats at the FAA who come to license the Dream Chaser will be all over this aspect of the design like a rash.

I didn't think much of SpaceDev bashing Griffin:

Heavy Lift of all kinds seems to be suffering lately. On page 41 of the Nov 28, 2005 AV Week is yet more bad news. The XCH-62 was the largest helicopter prototype made in the US. As you know the Army is leading the Joint Heavy Lift program.

So what did they do with the prototype?

They crushed it.

XCH-62 had been sitting around, waiting to be reborn--and now this. Heavy Lift just doesn't have support--people want sexy weapons. Sickening.

There is some good news. A company has a rolling platform that can lift 800 tons, and that might be a help to Musk, SpaceDev and even Rutan:

www.shuttlelift.com

In other news, Professor Mark West from the University of Manitoba has a new concept of using fabric formed concrete molds. This could be of some use not only on the moon but for Xprize candidates who need novel ways of building structures. Professor West was good enough to place his know-how in the public domain--free to anyone who wants it. This may be helpful to those of you who need a static test stand:

http://www.acresinnovations.com/summer2004/west_guest.html

In other news--

Sea Dragon, the largest of all sea-launched rockets, doesn't seem so big now. Jack Shick, a member of the American Polar Society has a patent on Iceberg Utilization, as described on page17 of the Spring-Summer 2004 issue of The Polar Times (Vol. 3, No 5). He can be contacted at [email protected] His patent may be found at www.uspto.gov --enter patent number 6688105, or try the link below:

http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=/netahtml/srchnum.htm&r=1&f=G&l=50&s1=6688105.WKU.&OS=PN/6688105&RS=PN/6688105

The tech needed for this could be used for Sea Dragon--a true HLLV
