Astronaut Moments: Don Pettit, Science of Opportunity

As NASA astronaut Don Pettit returns to the International Space Station for the fourth time, he will be bringing with him ideas… ideas for science experiments!
In addition to his duties onboard the space station, Pettit will be conducting what he calls “Science of Opportunity” – bonus science experiments of his own in addition to those he’ll work on day-to-day. These experiments could include everyday objects found on station, including liquid salt, powdered milk, and even Legos. As Pettit demonstrated in the past with his previous experiments, sometimes this bonus science leads to peer reviewed scientific papers and new discoveries, proving you never know until you try.
