The launch of a a suborbital sounding rocket hoping to explore energy transport in space was scrubbed Sunday evening due to higher level winds.

The next attempt of the launch will be Monday evening. However, if the current forecast holds, conditions do not appear to be conducive to a launch occurring.

The mission is scheduled for no earlier than 8:04 p.m. EDT with a 40-minute launch window. Backup launch days run through May 16. The launch may be visible, weather permitting, in much of the eastern United States from the Atlantic coast to the Mississippi River.

A four-stage Black Brant XII rocket will be used for the mission that includes the release of barium vapor that will form two green-violet clouds that may be visible for about 30 seconds. The barium vapor is not harmful to the environment or public health.

Wallops tweeted Monday afternoon that the forecast is looking much better for a possible launch tonight.
