Just a little nitpicking:

It is a Minotaur IV Lite launch vehicle.

DARPA release.

Will be keeping this thread on here, given the lack of a proper webcast.

A quick attempt at removing some of the noise in that feed by averaging 1800 frames.

Thanks Chris, bit of a shame OSC does not have their own dedicated feed, but that is commercial operations for you.

Anyhow, DARPA_News is live tweeting, and we have the above stream.

My understanding is that HTV-2 / Falcon is essentially unpowered after the boost phase, that it is testing flight control and aerodynamics at hypersonic regimes but not a power source (such as a scramjet).  The hypersonic engine test was the Waverider / X-51 test which unfortunately hit a snag June 13.

Is this correct?

I do not think X-51 "hit a snag" - the test was not successful, but not every test is successful and the failure did not stop the program.

HTV-2 is a glider - it has RCS engines, but no main engine.

Why? What value does Orbital or anyone gain for providing a live feed. Yes it  gives some of us instant gratification, but that does not put additional rockets on the table for Orbital. One could argue that if anything, nothing should be broadcast about this test least others (cough, Iran) get ideas.

Reminds me of the following XKCD, http://xkcd.com/932/

If you're happy and you know it,
It's your med's!

ULA thinks it is a good idea, and NRO does not mind launch coverage up to PLF sep.

Scheduled T-0 has been and gone, rocket is still sitting there. Plenty of window left though.

Somewhat surprised there’s no TDWR west of Las Vegas.

Edit: Oh, and another attempt at removing noise – this time with 4096 frames.
