In 1999, NASA sent 4 ladybugs aboard Columbia for 5 days to chase aphids; the aphids lost their ability to escape by falling, and the ladybugs still caught and ate them

In July 1999, space shuttle Columbia carried an unusual crew member into orbit as part of a student science project: four ladybugs. They flew in the STS-93 mission, which is described by NASA as a “planned five-day mission” commanded by Eileen Collins, the first female commander of the Space Shuttle. The University of Colorado Boulder’s press release regarding this mission stated that the experiment asked one simple question: if gravity disappeared, could ladybugs still eat aphids, their favorite food?
