Wallops launches an average of 25 scientific balloons each year. Balloons are launched routinely from the National Scientific Balloon Facility in Palestine, Texas and the Scientific Balloon Flight Facility in Ft. Sumner, New Mexico.

The Fungi for the Student Eye Experiment was
done with the help of Krista
McGuire, Ecology Doctoral
student from University of
Michigan.
![Page 7: Wallops launches an average of 25 scientific balloons each year. Balloons are launched routinely from the National Scientific Balloon Facility in Palestine,](https://reader036.fdocuments.in/reader036/viewer/2022062516/56649e385503460f94b29124/html5/thumbnails/7.jpg)
Students worked after school
hours to prepare the experiment for flight on a high altitude
balloon. Experiment vials were made for
use in near space
conditions.

Sordaria produces sac shaped
reproductive structures called asci. These burst
open to release spores.
Each spore case has rows of spores that
are produced through meiosis and found eight at a time
in a spore case.

Students used samples of
homozygous black and
homozygous tan Sordaria fungus from a prepared
culture. Each sample was
carefully placed in an experiment
vial.

Penicillium cultures
were also prepared for flight on the
mission.
Penicillium is used in the manufacture of medicines that cure bacterial illness
and infection.

Penicillin tablets were
also sent into near space
conditions to test their
efficacy after their return to
Earth.

The balloon gondola is brought
to the launch site by crane.

The HERO balloon is
inflated and prepared for
launch.
![Page 16: Wallops launches an average of 25 scientific balloons each year. Balloons are launched routinely from the National Scientific Balloon Facility in Palestine,](https://reader036.fdocuments.in/reader036/viewer/2022062516/56649e385503460f94b29124/html5/thumbnails/16.jpg)
The launch is complete at the Fort Sumner, New Mexico site.

The HERO payload lands
softly in a field in Kansas. The
equipment is in perfect condition at
recovery.

Once the experiments were returned from flight, the Sordaria tan was mated with the black Sordaria in order to determine if there was any change in the DNA.

Penicillin tablets were plates on Petri dishes with bacteria to test the efficacy of
the penicillin after exposure to near space conditions.
Penicillium culture was placed on Petri
dishes as well, to test the ability of
the fungi to inhibit bacterial growth
after its high altitude flight.

Students spent the day in the
lab using microscopes and other lab equipment to determine the
outcome of their
experiments.

The Fungi for the Student Eye experiment showed that the DNA of fungi can be altered by exposure to near space conditions. The lab report gives details of the students’ findings.

Young Scientists learned a lot about the work of real science and produced some interesting results for NASA’s space experiments program.
