[07/29/88 Update of NASA Balloon Mission]
|
||
|
||
-----------------------------------------------------------------------
|
||
|
||
NASA will launch three huge balloons in Canada next month to
|
||
search for cosmic rays, including those that could provide
|
||
evidence of galaxies made of antimatter.
|
||
|
||
Antimatter consists of particles with electrical charges
|
||
opposite those of "common" matter, which constitutes Earth's
|
||
material. When antimatter and matter collide there is a mutual
|
||
and complete annihilation, releasing energy far greater in
|
||
proportion then energy released by nuclear fission or fusion.
|
||
|
||
Whether antimatter could ever be created in sufficient
|
||
supply and harnessed to provide useful energy is a challenging
|
||
question.
|
||
|
||
The flights will begin Aug. 2, in a month-long campaign that
|
||
is part of the NASA Balloon Program managed by the Goddard Space
|
||
Flight Center's Wallops Flight Facility, Wallops Island, Va.
|
||
|
||
Balloons that will lift three cosmic ray experiments to
|
||
approximately 120,000 feet will be launched from Prince Albert
|
||
Saskatchewan Airport, approximately 300 miles north of the
|
||
U.S./Canadian border.
|
||
|
||
Scientific balloons are utilized to carry large research
|
||
payloads with scientific instruments to make measurements at
|
||
altitudes above 99 percent of the Earth's atmosphere. They are
|
||
made of a thin polyethylene material and are more than 350 feet
|
||
in diameter at full inflation. These balloons provide unique
|
||
experiment platforms for measurements at altitudes in the upper
|
||
stratosphere.
|
||
|
||
Personnel from WFF and the National Scientific Balloon
|
||
Facility, Palestine, Texas, will provide the launching and
|
||
operational flight support at the primary operations site in
|
||
Prince Albert. Personnel from WFF also will provide downrange
|
||
telemetry tracking support at Edmonton, Alberta.
|
||
|
||
Principal investigators for this campaign are Dr. Steve
|
||
Ahlen, Boston University; Dr. W. Robert Binns, Washington
|
||
University; and Dr. Steve Schindler, California Institute of
|
||
Technology.
|
||
|
||
Ahlen's extragalactic antimatter experiment is a 4,500-pound
|
||
payload that will search for heavy anti-nuclei (anti-silicon to
|
||
anti-iron), and will be flown on a 28.4 million cubic foot
|
||
balloon. The observed anti-nuclei are expected to provide
|
||
evidence for the existence of galaxies made completely of
|
||
antimatter. Scientist believe this discovery could prove to be
|
||
extremely useful for understanding the annihilation process
|
||
between matter and antimatter in the creation of galaxies.
|
||
|
||
Binns' payload, called the scintillating optic fiber
|
||
experiment is a 1,200-pound cosmic ray isotope experiment that
|
||
will utilize newly-developed range and trajectory-defining
|
||
detectors based on scintillating fiber optics. It also will be
|
||
carried aloft by a 28.4 million-cubic-foot balloon.
|
||
|
||
Schindler's 2,700-pound payload, to be carried on a 23.3
|
||
million-cubic-foot balloon, is the high energy isotope
|
||
spectrometer telescope. This experiment employs a combination of
|
||
scintillators and counters to form a cosmic ray isotope
|
||
spectrometer capable of measuring the isotopic composition of
|
||
cosmic rays from helium to nickle.
|
||
|
||
The mission is part of the overall NASA Balloon Program,
|
||
managed at Wallops. The program provides 40-45 balloon flights a
|
||
year from locations around the world.
