ESCAPE
II Overview
What is ESCAPE
II?
Escape II is a student-designed, constructed, tested, and organized
scientific payload that will study solar radiation as it affects
the thermosphere, a portion of the Earth's upper atmosphere. The
ESCAPE II project is an upgraded version of ESCAPE I which flew
in April of 1993. The ESCAPE II payload flew on the Space Shuttle
Atlantis in a Get-Away-Special canister in November of 1994 as a
secondary payload with the ATLAS III mission.
What is a
Get-Away-Special (GAS)?
The "GAS" program, developed by NASA, provides low cost
access to space for colleges and other research groups. The experiment
canister is bolted to the sides of the shuttle payload bay and is
roughly 3 feet tall and 23 inches in diameter. Power is supplied
by the experimenter.
What is the
Colorado Space Grant Consortium?
The Colorado
Space Grant Consortium (CSGC) is a group of thirteen Colorado colleges
and universities funded by NASA for the express purpose of educating
students of all ages in the science and engineering aspects of exploring
and working in space. The programs range from introductory education
for K-12students, to design and development of actual space projects
for undergraduate and graduate students.

How are students
Involved?
The ESCAPE II
payload has been designed, managed, and built entirely by students
at the University of Colorado at Boulder. Graduate and undergraduate
students from aerospace, mechanical, and electrical engineering,
as well as physics and other scientific disciplines, have been involved
since the project's inception. From project management to detailed
performance analysis, the students go beyond textbooks and in the
process build a sense of teamwork and professionalism.
What is the Purpose?
The ESCAPE II instruments take measurements of solar spectral radiation
in the extreme ultraviolet wavelengths. This is the frequency of
light absorbed by the thermosphere, the layer of the Earth's atmosphere
above the ozone layer.
By determining
how much solar energy is absorbed, the ESCAPE II project hopes to
add to the understanding of the effects of solar radiation on the
ozone layer and the greenhouse effect. The payload's Far Ultraviolet
Spectrometer (FARUS) will achieve this objective.
The payload
also has a digital imaging telescope to document solar surface activities,
such as plages and filaments, in an attempt to establish some correlation
between solar activity and Lyman-alpha radiation. Known as the Lyman-Alpha
Solar Imaging Telescope (LASIT), this instrument will provide some
of the first ultraviolet images of the sun since Skylab.
ESCAPE II effectively
proves that valuable science can be performed while maintaining
the "better, faster, cheaper" method. With a budget of
only $17,000 and a year and a half to produce the experiment, everyone
must excel at quality engineering, teamwork, and obtaining large
donations and cooperation from industry.

How is Industry
involved?
Many local Colorado
industries have generously contributed both expertise and equipment
to the ESCAPE II project. With professional experience to draw upon
during design reviews and daily work, students receive an invaluable
real-world education in designing for the harsh environment of space.
The equipment, testing facilities, and consultation donated by companies
such as Ball Aerospace, Martin Marietta, Motorola Corporation, Exabyte,
Fluke, Acton Research Corp., Gates Electronics, IBM, Hitachi Corporation,
NCR, Current Technologies Inc., TRW, Edmund Scientific, 3M, CID
Technologies, National Semiconductor, Hewlett Packard Corp., King
Electronics, Booker Electronics, and Eagle HI TECH Electronics have
allowed the ESCAPE II project to achieve far greater scientific
and educational goals than would have been possible in a strictly
internal university program.
