BELLEVUE, Wash. -- A science experiment created by a team of seventh grade students at Open Window School will be tested aboard the International Space Station (ISS) this year.

The experiment, proposed by Subi Lumala, Vivienne Rutherford and Catherine Whitmer, could help determine how to grow plants on Mars. It will test how microgravity impacts the growth of a small flowering plant, Arabidopsis, in simulated Martian soil.

Their experiment was one of 21 proposals, which were submitted by students across the United States and Canada, selected for the Student Spaceflight Experiments Program (SSEP).

Astronauts aboard the ISS will conduct the students' experiment in spring or summer 2016. An exact date has not been set.
