THE EXPERIMENT:
Will cosmic radiation increase the rate of mutations in yeast’s DNA? Will an antioxidant from green tea decrease the rate of mutations in DNA?
Proposal Summary: We want to know if astronauts can decrease their risk of cancer by taking an antioxidant supplement. Therefore, the question to be addressed by the experiment is:
Will cosmic radiation increase the rate of mutations in yeast’s DNA? Will an antioxidant from green tea decrease the rate of mutations in DNA?
We are using yeast because originally we wanted to test human cells in space but we found out that they would die before they got into space. The cells would not survive for several reasons: there is not enough oxygen, there would be no way to eliminate waste, there would not be enough nutrients, and it would not be warm enough. We will be using yeast as a model for human cells because they are very similar and easy to work with.
We will be testing yeast in saline and yeast in saline with an antioxidant from green tea to see if the antioxidant will protect the yeast from the cosmic radiation experienced in microgravity. On Earth we will have a control consisting of the exact same experiment. This will show us if there is an increased rate of damage to the yeast’s cells from the radiation and if the antioxidant will decrease the damage to the cells.
We hypothesize that the radiation will increase the rate of mutations in yeast’s DNA in space compared to the mutation rate on Earth. We also hypothesize that the antioxidant from green tea will decrease the mutations to yeast’s DNA.

The Student Spaceflight Experiments Program (SSEP) is a program of the National Center for Earth and Space Science Education (NCESSE) in the U.S., and the Arthur C. Clarke Institute for Space Education internationally. It is enabled through a strategic partnership with NanoRacks LLC, working with NASA under a Space Act Agreement as part of the utilization of the International Space Station as a National Laboratory. SSEP is the first pre-college STEM education program that is both a U.S. national initiative and implemented as an on-orbit commercial space venture.
The Smithsonian National Air and Space Museum, Center for the Advancement of Science in Space (CASIS), Carnegie Institution of Washington, NASA Nebraska Space Grant Consortium, and Subaru of America, Inc., are National Partners on the Student Spaceflight Experiments Program.
