On a bright and early Saturday morning, a group of Arizona State University students gathered in a remote desert area, just west of Quartzite, Arizona.
Their reason for being there? To launch two large weather balloons that can carry a payload (mechanically and thermally stable containers) near the edge of space so the students can study how high altitudes affect a variety of objects — in this case, lettuce seeds.
The students are part of ASU chapter of ASCEND (Aerospace Scholarships to Challenge and Educate New Discoverers), an Arizona Space Grant program that engages undergraduate students across the state in the full “design-build-fly-operate-analyze” cycle of a space mission.
They were joined by volunteers from Arizona Near Space Research, an affiliate of ASCEND that helps coordinate balloon launches.
The students prepared two different seed packets for the payloads — one on the outside that will be exposed to high-altitude radiation and one on the inside that will just be exposed to the high altitude — to see how both the altitude and radiation exposure affects the seeds.

Students watch as a payload and weather balloon take off. The balloons traveled upward of 100,000 feet before popping and parachuting back down to Earth in the Harcuvar Mountains Wilderness.
