NASA delays super pressure balloon launch
The launch of NASA\'s super pressure balloon - carrying a space observatory designed to detect high-energy cosmic rays - was postponed for the third time today due to poor weather conditions.
Washington: The launch of NASA's super pressure balloon - carrying a space observatory designed to detect high-energy cosmic rays - was postponed for the third time today due to poor weather conditions.
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.
No launch attempt is scheduled for tomorrow, NASA said in a blog post. This was the third scheduled launch attempt for NASA's 2017 Wanaka Balloon Campaign from New Zealand. The first attempt 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 super pressure balloon (SPB) technology with the goal of long-duration flight of over 100 days at mid-latitudes.
In addition, the Extreme Universe Space Observatory on a Super Pressure Balloon (EUSO-SPB) will be on the test flight. EUSO-SPB is designed to detect high-energy cosmic rays originating from outside our galaxy as they penetrate the Earth's atmosphere.
NASA estimates the balloon will circumnavigate the globe about the southern hemisphere's mid-latitudes once every one to three weeks, depending on wind speeds in the stratosphere.
