Flight qualification mission for the Stratofilm SF-450 / 37 "Heavy" balloon.
Details of the balloon flight and scientific outcome
Launch site: Scientific Flight Balloon Facility, Fort Sumner, (NM), US
Balloon launched by: Columbia Scientific Balloon Facility (CSBF)
Balloon manufacturer/size/composition: Zero Pressure Balloon Raven - 37.000.000 cu ft
Flight identification number: 572NT

The balloon was launched by dynamic method assisted by launch vehicle on August 30 at 15:10 UTC. After a nominal ascent phase the balloon started to flight due west as can be seen in the map at right (click to enlarge). After a total flight time of 5 hours, 50 minutes, the balloon was terminated approximately 80 miles SW of the launch base. Recovery of the payload and balloon was completed on August 31.
According to the post flight report of the agency, the mission was an operations and science success, exceeding all preflight minimum requirements for the balloon and all test articles. The balloon performance was within specifications for inflation, launch, ascent, entry into float, and in float stability.
The termination used normal termination procedures, with the test ripstitch system operating in-line. The on-board video showed that the ripstitch system significantly reduced the parachute opening shock. The parachute was successfully separated by the SAPR (semi-automatic parachute release) system operating in the on-line mode, with the GAPR system also operating successfully in an off-line mode in parallel with the SAPR.
