NASA aborted plans to launch a rocket Monday night because of cloud cover.
This was the sixth failed attempt to launch the much-anticipated rocket.
The rocket was expected to create a multi-colored light show visible to people along the East Coast from New York to North Carolina.
The launch of the Terrier-Improved Malemute sounding rocket has been delayed several times since its original launch date of May 31.
Reasons for scrubbing the launch have varied, from strong upper-level winds and clouds to boats in the potential landing area. It is set to launch from Wallops Flight Facility on the eastern shore of Virginia Monday night as mostly clear skies are expected for much of the East Coast.
Four to five minutes after launch, the rocket is expected to deploy 10 canisters about the size of soft-drink cans, each containing a colored vapor that forms artificial, luminescent clouds.
The clouds, or vapor tracers, are formed “through the interaction of barium, strontium, and cupric-oxide,” according to NASA.
Since the canisters will be released about 100 miles (160 kilometers) above the ground, the space agency says they “pose absolutely no hazard to residents along the mid-Atlantic coast.” Sounding rockets have been used for more than 40 years to carry science payloads on missions that last just five to 20 minutes.
The vapor tracers will allow scientists on the ground to view the movement of the particles in the ionosphere, a part of the Earth’s atmosphere that stretches to the edge of space, to learn more about the movement of the air currents at that altitude.
The whole mission will last only about eight minutes before the payload lands in the Atlantic Ocean, about 90 miles out to sea from its launch point in Virginia.
Morning coffee with a light show
“The vapor tracers could be visible from New York to North Carolina and westward to Charlottesville, Virginia,” NASA said.
If you are north of the launch site — say, in Washington, Philadelphia or New York — the clouds will appear in the lower southeastern sky. If you are to the south — in Norfolk, Virginia Beach or the Outer Banks of North Carolina — look toward the northeastern horizon. Richmond and Charlottesville residents should be able to see the clouds directly to the east.
Not on the East Coast? No worries — NASA has you covered with a livestream and continuous updates on the Wallops Facebook and Twitter sites. Smartphone users can download the “What’s Up at Wallops” app to get more launch information, NASA says.
