Update: Turns out seven wasn't Wallops' lucky number. The launch has been scrubbed due to cloudy skies. They'll try again tomorrow night, with a launch window through June 18.
Monday's launch was scrubbed due to cloud coverage at both Wallops and NASA's Duck, N.C. center, and a boat down range from the launch site canceled Sunday's attempt.
The total flight time for the Terrier-Improved Malemute's mission is expected to be about 8 minutes.
