Moldy Mouse Food Postpones SpaceX Launch [phys.org]:
SpaceX has postponed its cargo launch to the International Space Station until Wednesday after mold was found on food bars for a mouse experiment bound for the orbiting outpost, NASA said.
[...] Some 40 mice are part of the experiment aimed at studying the effects of microgravity in the immune system.
The launch will be the 16th for SpaceX, as part of an ongoing contract with NASA to send supplies to the astronauts living at the space station.
Some 5,600 pounds (2,500 kilograms) of food, experiments and other gear is packed onto the unmanned Dragon cargo ship, which will blast off on a Falcon 9 rocket from Cape Canaveral, Florida.
Figuring in the cost of the delay, that has to be some of the most expensive mouse food, ever!
