TIFR Stratospheric Balloon Penetrates into Mesosphere for The First Time

Under the High Altitude Balloon Development Project (HAA) a 61,000 cubic meters balloon indigenously developed in India at Balloon Facility, Tata Institute of Fundamental Research, Hyderabad penetrated into the Mesosphere for the first time in India. So far only balloons from USA and Japan have accomplished this feat.

TIFR Stratospheric Balloon Penetrates Into Mesosphere

The 61K cubic meter balloon weighing 31.0 Kilograms was manufactured at Balloon Facility using the indigenously developed ultra-thin polyethylene film of thickness 3.8 micro meters (in comparison the finest human hair is around 17 micro meters in diameter). The balloon carried a payload of 7.9 kilograms comprising Single Card Tele-Command with integrated Electronic Timer, Radio Trans receiver (Data Modem), Air traffic Control Transponder, Mobile telephony GSM-GPS for last leg tracking, upward looking video camera and two GPS-sondes for navigation and measurement of atmospheric parameters like pressure, temperature and humidity with a 4.3 meter diameter parachute weighing 3 kilograms for the safe recovery of instruments after the flight.

The balloon was launched at 0402 hours IST of January 7th 2014 from Balloon Facility campus located near Moula-Ali. The balloon reached the maximum altitude of 51.661 kilometers in 2 hours 9 minutes and created the record. The flight was terminated at 0704 hours IST using Tele-Command. All the instruments performed well during the flight. The instruments safely landed near Husnabad town, Siddipet mandal, Karimnagar district, Andhra pradesh and the recovery crew recovered the payload intact.

This is for the first time that a regular stratospheric balloon has penetrated the Mesosphere in India.

This breakthrough will provide an opportunity for our scientists working in the area of atmospheric dynamics to conduct experiments and collect data up to 50 kilometers. Development work on increasing the payload capability of this balloon is in progress and the next flight with payload of 15 kilograms is planned during summer 2014 flight programme.
