NASA Asks Boeing, SpaceX To Stop Work On Next-Gen Space Taxi

BarbaraHudson writes Due to a challenge by Sierra Nevada, NASA has asked the winners for the next earth-to-orbit launch vehicles to halt work, at least temporarily. "After rewarding Boeing and SpaceX with the contracts to build the spacecrafts NASA is now asking the companies to stop their work on the project. The move comes after aerospace company Sierra Nevada filed a protest of the decision after losing out on the bid. Sierra Nevada was competing against Boeing and SpaceX for a share of the $6.8 billion CCP contracts. The contracts will cover all phases of development as well as testing and operational flights. Each contract will cover a minimum of two flights and a maximum of four, with each agency required to have one test flight with a NASA representative on board.... According to NASA's Public Affairs Office, this legal protest stops all work currently being done under these contracts. However, officials have not commented on whether-or-not the companies can continue working if they are using private funds."

Maybe affects Boeing, not SpaceX

I really doubt SpaceX is going to stop work on a vehicle they were developing before they were awarded the contract.

Boeing, on the other hand...

well that really gets at the heart of the matter doesn't it? SpaceX is going to Mars, with or without NASA. Boeing is doing whatever somebody pays it to do.

Business as usual

Filing a protest after someone else gets the contract is pretty much automatic.

Ridiculous

Sorry, but nobody wants your miniature space shuttle, Sierra Nevada. Probably should have thought a little harder before copying one of the most expensive and unreliable space systems used in recent times. Heat-shield > Everything. Now SpaceX/Boeing have to bite the bullet and stop work? Something very wrong with this way of doing things.

A space plane isn't inherently unreliable. Placing said space plane below the level of cryogenic fuel tank insulation, with ice subject to crashing into it at hundreds of miles an hour is, in retrospect, pretty silly. Dream Chaser (DC) sits at the top of the rocket stack - it's smaller than the space shuttle, so this is feasible.

Putting the space plane on top of the stack isn't without it's own problems though... mainly in the form of huge aerodynamic issues because the wings are now where they can exert the greatest leverage. (Read among other things: in the exact right spot to cause the most control problems and to tear the stack to shreds if there's only a small problem with the angle of attack.) That's why the Dyansoar's Titan booster had suchhuge fins, simply gimbaling the engines did not provide sufficient control authority to offset the resistance of the wings.

For the record, as a huge fan of Spacex, I don't think the DC needs to be trashed on - it was a good (not great) proposal stuck between the big PR darling and the politically best-connected contractor in the business.

You forgot: "and was the most technically difficult proposal and submitted by the contractor with the least experience of any kind". Sierra Nevada has no substantial grounds for complaint, their solution may have been competitive on price, but contrary to popular belief these types of contracts are NOT awarded solely on the basis of costs. Technical factors also play a huge role. Which also explains the award to Boeing, it wasn't political connections, it was because SpaceX has a damm poor track record when it comes to delivering on time.

Most who remember the TV show 6 million dollar man, that was footage of a DynaSoar's unsuccessful landing

Nope...that footage was of two experimental lifting-body aircraft from Northrop, the HL-10 and M2-F2. The crash footage was of the M2-F2. Earlier in the credits, the HL-10 is shown being dropped from a B-52.

I'm nearly certain

...that in 100 years, historians will postulate that the US space program really vanished into the bureaucratic morass, and that politics and special interests combined to torpedo any hope that the private sector would ever make it into space.
