This week Reactions makes first contact with the kerbalnauts! Through the fun of Kerbal Space Program, we examine the chemistry of rockets. Featuring Doane College Postdoctoral Fellow Raychelle Burks, Ph.D., we look at solid and liquid propellants and the “ride-able explosion” that is a rocket launch.
