CAPE CANAVERAL, Fla. (AP/WKYT) - SpaceX will have to wait at least another day to launch from NASA's historic moon pad.
Last-minute rocket trouble forced SpaceX to halt Saturday's countdown at Florida's Kennedy Space Center.
The unmanned Falcon rocket remains at Launch Complex 39A, waiting to soar on a space station delivery mission. It's the same pad where Americans flew to the moon almost a half-century ago, and where the shuttle program ended in 2011.
This will be SpaceX's first Florida launch since a rocket explosion last summer.
The rocket is carrying re-supply materials for the International Space Station, including a cell culturing biology experiment designed by two Craft Academy students. The Craft Academy for Excellence in Science and Mathematics is a residential high school at Morehead State University.
Craft Academy seniors Will Casto and Danielle Gibson along with MSU professor Dr. Michael E. Fultz will be able to study the effects of microgravity on muscle contraction.
The next launch attempt could come as early as Sunday morning.
