POP # 1 (Polar Observation Platform)

Developed by ISTAR Group / Universita di Roma La Sapienza

Balloon launched on 1/7/2011, from Ny-Alesund, Svalbard, Norway

Purpose of the flight and payload description

The aim of the POP (Polar Observation Platform) initiative was to demonstrate the feasibility of long-duration stratospheric-balloon flights during the polar night in the Arctic. The effort was carried out through a cooperation between the University ''la Sapienza" of Rome and the ISTAR-Group (International Science Technology and Research) from the United States. Balloons were launched with the support of the Consiglio Nazionale delle Ricerche that offered the facilities of the Dirigible Italia base in Ny Alesund, Spitzbergen Island in Svalbard.

Objectives of the 2011 campaign was to observe, in real time, the polar winter night sky stratospheric wind trajectories for planning future campaigns with heavy lift Long Duration Balloons (LDB) during the polar night. The advantage of a winter flight offers the science teams observations without the solar radiation experienced during the summer months.

The payload carried out by the balloon was simple battery powered ARGOS / GPS transmitter that delivered time, temperature, speed, heading, and altitude.

Details of the balloon flight

Balloon launched on: 1/7/2011 at 19:00 utc
Launch site: Ny-Alesund, Svalbard, Norway  
Balloon launched by: ISTAR (International Science Technology And Research)
Balloon manufacturer/size/composition: Zero Pressure Balloon Near Space Corporation - 2523 m3
End of flight (L for landing time, W for last contact, otherwise termination time): 1/7/2011 at 21:00 utc
Balloon flight duration (F: time at float only, otherwise total flight time in d:days / h:hours or m:minutes - ): 2 h
Landing site: In a Glacier at 79º 03' N 12º 22' E. Svalbard Archipelago

The balloon was launched from Ny Alesund, Spitzbergen Island on January 7, 2011 at 19:00 utc in mild conditions, with a temperature of -12º C and wind of 2 kts. The balloon ascended nominally but then began to descend after reaching an altitude of 18 km. After a few minutes the balloon landed on a glacier approximately 79º 03' 30" N 12º 22' 26" E. Recovery of the balloon and payload was delayed to the moment when the daylight returned to the far north.
