Cocaine found at NASA Kennedy Space Center

NASA has launched an investigation after cocaine was discovered at Florida's Kennedy Space Center, according to reports.

A NASA spokesman told reporters on Tuesday that 4.2 grams of "a white powdery substance" was found last Monday at the NASA facility and tested positive for cocaine.

"Law enforcement personnel field tested the substance, which indicated a positive test for cocaine," Renee Juhans, an executive officer with the office, told CNN. "The substance is now at an accredited crime lab for further testing." She wouldn't comment on where in the facility the drug was found.

Although NASA has a zero-tolerance policy for drugs, this is the second time in just over a year since cocaine was discovered at the facility. In January 2010 a small amount was found in the hangar that housed space shuttle Discovery, which, incidentally landed back on Earth last Wednesday. It will spend the rest of its days in a museum. NASA is now prepping for the launch of space shuttle Endeavour, which is expected to launch on April 19. The 14-day mission will be led by Commander Mark Kelly, the husband of Rep. Gabrielle Giffords, who was shot at an Arizona shopping mall in January.
