WALLOPS ISLAND, Va. (AP) -- High cirrus clouds have postponed the launch of two sounding rockets from NASA's Wallops Island Facility in Virginia.
The launches will support a joint project between NASA and the Japanese Aerospace Exploration Agency to study a global electrical current that sweeps through the ionosphere.
NASA says clear skies are needed for the project.
The Black Brant V and Terrier-Improved Orion were scheduled to be launched 15 seconds apart Monday morning. NASA scrubbed the launch and rescheduled it for Tuesday between 9:30 a.m. and 11:30 a.m.
NASA says the single-stage Black Brant V will collect data on the neutral and charged particles through which it travels through.
A trail of lithium gas will be shot out from the two-stage Terrier-Improved Orion to track how the upper atmospheric wind varies with altitude.
