Successful Sweden Campaign07.01.2013

SUNRISE Tracking Map

NASA's Balloon Program Office based at Wallops Flight Facility has completed another successful Sweden balloon flight campaign. The National Center for Atmospheric Research (NCAR) SUNRISE II instrument was successfully launched on June 12, 2013 at 05:38 (UTC) from the Esrange Space Center near Kiruna, Sweden. The mission flew aboard a 963,000 m3 (34 million cubic foot) balloon at approximately 37 km (120,000 feet) traversed west over Sweden, Norway, the Norwegian Sea, Greenland, and was terminated by command over the Boothia peninsula in northern Canada with a total flight time of 5 days, 7 hours, 4 minutes. 

The SUNRISE II mission's main goal is to shed light on the solar magnetic field. The project aims at high-resolution spectro-polarimetric observations of the solar atmosphere on the intrinsic spatial scale of its magnetic structure. The SUNRISE telescope with 1 m (3.3 feet) aperture and its instruments will provide spectra and images resolving spatial scales down to 100 km on the Sun. Recovery of the payload and support equipment has been completed and post flight data reduction is now ongoing. 

The principal investigator of the SUNRISE II mission is Dr. Michael Knoelker of NCAR.
