Nasa is investigating after cocaine was found in a facility at the Kennedy Space Centre in Florida.
Nasa spokesman Allard Beutel said today that 4.2 grams of a white powdery substance was found last week at the Nasa facility, though he would not say where.
It tested positive for cocaine.
It's not the first time cocaine has been found at the space centre.
A small amount was discovered in January 2010 in a secure part of a hangar that housed space shuttle Discovery.Reuse content
