At Wallops, the launch of a Terrier-Improved-Malemute sounding rocket, carrying the SubTec-6 (46.007GP) payload was scrubbed for the day due to poor science conditions, winds exceeding limits and boats in the hazard area.
The next launch attempt will be Sunday, June 29 with a window of 4-5 a.m.

Boats in the hazard area? Crowd sourced launch webcast, maybe.

They should have added 'Klingons on the starboard bow' as well...

Bad luck at Wallops; the launch of the Terrier-Improved-Malemute (SubTec-6 mission) has been scrubbed again (just like the previous days). New try on July 2 at 04:36 EDT.

The flight of a Terrier-Improved Malemute sounding rocket from NASA’s Wallops Flight Facility ended prematurely today at 4:36 a.m. EDT about 19 seconds after its launch.
Range controllers detected a flight anomaly with the second stage Improved Malemute motor; the vehicle flew to an altitude of 27,000 feet and impacted about one nautical mile downrange.
There were no injuries or property damage as the vehicle landed in the established hazard zone in the Atlantic Ocean, which was cleared prior to launch.
A NASA team will investigate the cause of the flight anomaly and more information will be released as it becomes availablehttp://www.nasa.gov/content/wallops/nasa-to-test-suborbital-rocket-technologies/#.U7PQ4fldUuc

Thanks for the quick link to the youtube! I work here at Wallops and this is the most info I've been able to find so far. I'm sure there is going to be a lot of work to get this figured out ASAP. There is supposed to be another launch of this vehicle type in a month and a half or so and also several this winter in Alaska.

Background information on Terrier-Improved Malemute.

On the video, I thought that I saw the "Thiokol TU-758" second stage rocket motor exhausting at both ends. This is usually how flight termination systems work for solid motors, but I'm not sure if that setup is used for sounding rockets. Whatever the problem, it began at the moment of planned second stage ignition.
- Ed Kyle
There isn't currently an FTS design for the 49.xxx vehicle stack. That doesn't mean that one couldn't be designed of course. Generally they don't require FTS for sounding rocket launches out of Wallops.
Both pages describe the "Terrier Malemute" (Terrier Mk12 booster with custom built Thiokol TU-758 upper stage), while the "Terrier improved Malemute" consists of an Terrier Mk70 booster and a surplus Patriot missile motor as second stage.
Correct! To my understanding, the TU-758 was essentially a "dumbed down" version of the original patriot motor. NASA wasn't allowed to buy the patriot motors when they were new or something like that. Cut to several tens of years later, and original patriot motors are now available to NASA for all but free. A very small fraction of what they cost new anyway.

Thanks for catching that. It looks like NASA's web page is mis-titled. Is the photo of an "Improved" version?
- Ed Kyle
Negative. The improved version is very apparent due to its bright orange red RTV layer. Also the white stripes down the side.

Gaza rockets, their construction techniques, and safing are off topic. Posts trimmed.
