Report on the Nuclear Compton Telescope accident in Northern Australia
causes related to insufficient risk analysis, contingency planning, personnel training, technical knowledge, government oversight and public safety accommodations………Immediately after the accident in Australia, launch operations at all of NASA’s balloon sites were suspended.
NASA Releases Report About Australia Balloon Mishap, Space Daily, Oct 25, 2010 A NASA panel that investigated the unsuccessful April 28 launch of a scientific balloon from Alice Springs, Australia, has released its report.
NASA was attempting to launch the balloon carrying a gamma-ray telescope belonging to the University of California at Berkeley. The Nuclear Compton Telescope, which was partially destroyed in the accident, was designed to look for distant galaxies from a vantage point high in Earth’s upper atmosphere.
The scientific payload inadvertently separated from a mobile crane being used for the launch, and it was dragged approximately 150 yards by the airborne balloon. Spectators narrowly escaped injury when the payload hit an airport fence and a car……. The board’s report listed 25 proximate, intermediate and root causes related to insufficient risk analysis, contingency planning, personnel training, technical knowledge, government oversight and public safety accommodations…… in the course of our investigation, we found surprisingly few documented procedures for balloon launches. No one considered the launch phase to be a potential hazard.”…..
Immediately after the accident in Australia, launch operations at all of NASA’s balloon sites were suspended. NASA’s Balloon Program Office will resume launches once it has implemented and verified new procedures to safeguard launch crews and the public.
