This
picture was taken about 40 minutes into flight by a Canon digital camera
attached to a weather balloon. The balloon was launched by Randy Edelman, a
technology education teacher at the Philipsburg-Osceola area junior high school
in Pennsylvania, and his students. The balloon carried the camera, which sat
inside a foam cooler, 60,000 to 90,000 feet in the air in an attempt to capture
photos of the curvature of the Earth, the thin veil of its atmosphere and the
darkness of space.

the Earth. This picture was taken by a Canon digital camera attached to a
weather balloon and launched by Randy Edelman, a technology education teacher
at the Philipsburg-Osceola area junior high school in Pennsylvania, and his
students. The balloon carried the camera, which sat inside a foam cooler,
60,000 to 90,000 feet in the air in an attempt to capture photos of the
curvature of the Earth, the thin veil of its atmosphere and the darkness of
space.
Edelman came up with the idea after
reading about students at MIT who accomplished a similar experiment. Edelman
planned the project with Seth Wilberding, a doctoral student from Pennsylvania
State University who volunteers at the school one day a week through a National
Science Foundation partnership.
While in the classroom, Edelman had his
students calculate how the altitude, pressure and climate would affect the rate
of ascent and descent of the balloon. Then the group placed a Canon digital
camera inside a Styrofoam cooler and surrounded it with newspaper and hand
warmers to keep the electronics warm at 90,000 feet, where temperatures can go
below 50 degrees Fahrenheit. The camera was programmed to take photos every 12
seconds. They painted the cooler bright orange so it would be easier to spot
and attached a parachute to it for safe landing.
The cooler was launched on a windy day
from the high-school baseball field in Philipsburg. It stayed aloft for 72
minutes, after which it landed about 90 miles away in the town of Newport,
between Lewistown and Harrisburg. Edelman was able to safely retrieve the
cooler from its landing spot in a tree 70 feet in the air.
The experiment was a success, yielding
388 pictures, some of which were snapped at 60,000 to 90,000 feet--two or three
times as high as planes fly. Other shots included aerial views of Interstate
99, U.S. Route 322, Philipsburg, State College and other local landmarks.
Edelman funded most of the project with
a $500 education grant from the McDonalds Corporation. (Date of Images: June 2011)
