Guess someone outside of the shuttle program has a need for down mass...

Where is Vt_hokie?

I thought he would have brought this up sooner. First NASA, then DARPA, now USAF the X-37 is getting around. Looks to me like they are going to do what NASA planned on doing, use it as a TPS evaluation system. Also evaluating guidance, navigation and control systems. Lets see...
Non-ballistic autonomous fast response bomber?
Anti-satellite weapons platform?
ABM weapons platform?

not an Atlas 5 but an EELV.
Down mass is not part of the equation.
Too small for any retrievals.
It flies inside of the fairing at launch.

In one of my many tasks, I was working X-37 OTV-launch vehicle integration before it was cancelled.

The release says they have chosen Atlas 5.

my post got deleted.

I overlooked the part about Atlas V in the article.  NASA was going compete the launch service.

It will need a 5m fairing

More power to them, I hope they succeed. I've told Hokie and others that spaceplanes were coming; on a long and slow road.

It is too small to be manned.

This is a spaceplane and not an RLV.  It is a spacecraft that has wings.   It gets placed in its final orbit just like any other satellite.

"The OTV would be the first vehicle developed since the space shuttle with the ability to return experiments to Earth for further inspection and analysis."

Guess someone forgot all about Progress M!

Offline JWag

This is exciting, and I'm glad it's going to fly that soon.

Interesting that it will fly aboard an Atlas, but presumably the "flight" airframes will be built by Boeing (who built the drop-test craft).

 

Here's hoping for a great many interesting and educational flights.

Boeing spacecraft have flown on many Atlases and the same for LM spacecraft on Delta

There are "firewalls" to prevent spacecraft divisions from working directly with the launch vehicle divisions of the same company.  MRO personel had no Atlas launch experience, only Delta II

XSS-11-heritage? Interesting. Did you see this somewhere or just guessing?

Does anybody know if they are still planning to use the peroxide/kerosene AR2-3 rocket engine on the X-37?

That was changed to hypergolic engines when NASA ran the program.

Are there any diagrams or pictures that shows how the X-37/Atlas 5 configuration will look?  Inquiring minds would like to know!

I have only notional ones and I can't show the.   It would be inside of the fairing on top of the Centaur like any other spacecraft.

And actually it would be too early for the diagrams.  Originally, it was going to fly on a Delta II Heavy and then Boeing errorous thought it would fly on a Delta IV.  But it had to be competed and the prep for the RFP is where it was left off.

Delta II Heavy and 5-m fairing don't go together.  Was it going to be out in the airstream?
