Purpose of the flight and payload description
The primary objective of this flight was to test the behaviour of a new gondola developed to measure trace gas profiles in the stratosphere. The long term goal of the project was to compare the results obtained by the balloon with simultaneously performed measurements of the LIMS (Limb Infrared Monitor of the Stratosphere) instrument aboard the NIMBUS 7 satellite.
The balloon gondola (image at left) was designed and built to provide a sun pointing capability by means of two axis of stabilization to better than 3 arc mins. It used a twin axis sun sensor controlling an experiment mounting plate in elevation and the complete gondola in azimuth.
Details of the balloon flight
Balloon launched on: 7/13/1978 at 00:08 utc
Launch site: DLR Oberpfaffenhofen, Munich, Germany
Balloon launched by: MORABA (Mobile Raketen Basis)
Balloon manufacturer/size/composition: Zero Pressure Balloon
End of flight (L for landing time, W for last contact, otherwise termination time): 7/13/1978
Balloon flight duration (F: time at float only, otherwise total flight time in d:days / h:hours or m:minutes - ): 1 h 12 m
This was the first engineering test flight of the pointing LIMS gondola and was aimed to test its behaviour with no scientific instruments onboard. It was prematurely cut down before sun rise and only limited thermal data was gathered.
