College students and K-12 teachers are set to take a ride on a "Vomit Comet" this week in the name of science.
As part of NASA's reduced gravity education program, seven teams of undergraduates and seven teams of classroom teachers will perform carefully designed experiments under weightless conditions during a set of parabolic flights out of Johnson Space Center in Houston.
Flying aboard a specially modified jetliner that climbs and then rapidly descends simulates the feeling of weightlessness that astronauts experience in space. This sometimes makes passengers feel ill (thus the nickname), but it also provides a rare opportunity to test the effects of microgravity without launching into orbit.

The competitively selected groups have been building their experiments over that last six to nine months to prepare for their moments in microgravity, Frank Prochaska, the program's manager, told SPACE.com. There will be four flights total from Tuesday (July 16) to Friday (July 19) and each will run through a series of 32 parabolas with 30 seconds of weightless in each.
"They'll be testing everything from the way oil and water behave in microgravity to the way light reacts in microgravity," Prochaska said.
For example, a student team from Purdue University, made up of six flyers and one ground support, will be testing how to reduce excess water in fuel cells, which could have implications for propulsion systems on Earth and in satellites orbiting the planet.
"If they have too much water on the reaction surface, the fuel cell doesn't work as well as it could," Purdue team member Patrick Griffin, an aeronautical and astronautical engineering major, told SPACE.com.
Griffin was looking forward to experiencing weightlessness on board the flight but said he was also excited to see how other teams have organized their experiments, calling the process "a really hard thing to do in engineering."
SPACE.com Managing Editor Tariq Malik will also take a ride on the Vomit Comet this week. He will experience weightlessness with a group of students from the University of California San Diego that are testing how biofuels burn in weightless conditions.
