Onlookers Narrowly Avoid NASA Balloon Crash
After announcing a delay
in the final launch of the space shuttle program earlier this week,
NASA suffered another setback when a giant scientific weather balloon,
scheduled to fly high in the earth's atmosphere and laden with
expensive technological equipment, crashed during an attempted launch
in Australia. An Associated Press video shows the craft barreling
across the desert, smashing into the parked cars of onlookers, some who
narrowly escaped injury.
Australian news channel ABC interviewed
eyewitness Betty Davies, who said she and her husband were sitting in a
car next to one smashed by the gondola portion of the craft. "I think
if it hadn't have been for the other gentleman's car being there we'd
have been somewhere else by now," she said. "We were expecting to be
wiped out."
A status report released by NASA confirmed that upon release, the
balloon's payload hit the ground and was dragged approximately 150
yards before hitting a fence and sports utility vehicle. A mishap
investigation board is being convened. The balloon was attempting to
launch the Nuclear Compton Telescope, or NCT, a $2 million gamma-ray
telescope from the University of California, in Berkeley. The payload
is designed to study astrophysical sources of nuclear line emission
with high spectral and spatial resolution.
"Damage to the NCT payload, project assets and area surroundings are currently being assessed," the space agency announced.
The Compton imaging serves three purposes: imaging the sky, measuring
polarization and very effectively reducing background. NCT's guiding
principle is that high efficiency and excellent background reduction
are critical for advances in soft gamma-ray sensitivity. It employs a
novel Compton telescope design, utilizing twelve 3D imaging, high
spectral resolution germanium detectors (GeDs), enclosed on the sides
and bottom, and with an overall field-of-view (FOV) of 25 percent of
the sky, according to a Berkley mission statement.
An undergraduate student of the NCT project, Eric Bellm, posted his thoughts
on the crash on his blog Dispatches from the Field. The blog has since
been made private, but some statements are available on cached pages.
"It's hard to find words to describe what just happened. We had a
complete launch failure and abort, and much of the gondola and its
systems were destroyed," he wrote. "Thankfully no one was hurt. A full
accounting will have to wait-for now we're just trying to pick up the
pieces."
A day following the incident, NASA announced it would provide live
coverage of the May 6 launch of the Pad Abort 1 flight test. Pad Abort
1 will be the first fully integrated test of the launch abort system
being developed for the Orion crew vehicle. The information gathered
through the test will be used to design and develop future systems that
provide a safe escape for crews in the event of an emergency.
