Poor weather postpones NASA balloon launch
"Wind speeds were just slightly above those required for launch, and with the uncertainty for precipitation in the area, the team made the decision to postpone for the day," NASA scientists said in a blog post.
No launch attempt is scheduled for Tuesday. NASA will announce by 2pm on Tuesday, whether Wednesday's weather will support a launch attempt.
The first attempt to launch the balloon designed to carry a pioneering telescope to detect ultra-high-energy cosmic rays from near space was cancelled due to unacceptable stratospheric wind conditions.
The second attempt was cancelled due to a mechanical issue with a crane used for launch operations, which has since been resolved.
The purpose of the flight is to test and validate the SPB technology with the goal of long-duration flight at mid-latitudes.
In addition, the University of Chicago's Extreme Universe Space Observatory on a Super Pressure Balloon is a mission of opportunity flying on the 2017 SPB test flight.
