NASA’s scientific balloon program is finally resuming flights this month after a mishap back in April put a hault on the project.
The high-altitude balloons fly instruments for scientific and technological investigations that help us better understand the universe. The scientific balloons are composed of a lightweight polyethylene film and fly to altitudes of nearly 25 miles carrying payloads weighing up to 6,000 pounds.
Recently, NASA listed a total of 25 causes of the accident including insufficient risk analysis, contingency planning, personnel training, government oversight and public safety accommodations. After an intense evaluation of safety processes following the failed launch attempt from Australia, NASA has deemed the balloons ready for departure."
