The morning skies along the
mid-Atlantic coast will light up with luminescent clouds as NASA
tests a new system that supports science studies of the ionosphere
and aurora with a sounding rocket launch June 29 from the
Wallops Flight Facility on the eastern shore of Virginia.
During the flight of a two-stage
Terrier-Improved Malemute sounding rocket at 4:15 a.m. EDT, ten canisters about the size of a soft drink can will
be deployed in the air.
The canisters will deploy between four
and five minutes after launch. Blue-green and red vapor forming
artificial clouds should be visible. These clouds or vapor tracers
allow scientists on the ground to visually track particle motions in
space.
The development of the multi-canister
or ampule ejection system will allow scientists to gather information
over a much larger area than previously allowed when deploying the
vapor just from the main payload.
Ground cameras will be stationed at
Wallops and in Duck, N.C., to view the vapor tracers. Clear
skies are preferred, but not required, at both sites for the launch
to occur.
The vapor tracers are formed through
the interaction of barium, strontium and cupric-oxide. The tracers
will be released at altitudes 96 to 124 miles high and pose
absolutely no hazard to residents along the mid-Atlantic coast.
The vapor tracers could be visible
from New York to North Carolina and westward
to Charlottesville, Va.
The total flight time for the mission
is expected to be about eight minutes. The payload will land in
the Atlantic Ocean about 90 miles from Wallops Island and
will not be recovered.
