WALLOPS ISLAND, Va. (AP) — NASA has postponed for a second time a rocket launch with student experiments from its Wallops Flight Facility in Virginia.

A launch that was scheduled for Friday at Wallops Island was postponed. No new launch date was set. Friday's launch had been rescheduled from Thursday.

NASA says the rocket contains four university experiments as part of a project designed to provide students experience in designing, fabricating, testing and conducting experiments for space flight. After a 15-minute flight, the payload will splash down about 66 miles off the Virginia coast and will be recovered for re-use and experiment analysis.

The experiments are by students from Baylor University, the University of Colorado, the University of Puerto Rico and Virginia Tech.
