TIFR to launch 10 balloon flights for research

Hyderabad: The Tata Institute of Fundamental Research (TIFR) today said 10-balloon flights will be launched from Hyderabad for scientific purpose under the auspices of the Department of Atomic Energy and Indian Space Research Organisation (ISRO). The balloons will be launched from November 15, 2016 to April 30, 2017.

The balloons filled with Hydrogen gas, carrying scientific instruments will be launched from Balloon Facility of Tata Institute of Fundamental Research, ECIL, Hyderabad. The first balloon flight is planned around the 3rd week of November. The balloons are made of twin (polyethylene) plastic films, ranging in diameters from 50 mtrs to 85 mtrs.

The balloons, which carry scientific instruments for research at high altitudes, are expected to reach at a height between 30 km to 42 km depending upon the experiments being undertaken. The instruments will be kept at these heights for periods ranging from a few to 10 hours and then they will be released from the balloon.

After release, the instruments will come down to ground on large coloured parachutes. During ascent and at ceiling, the balloons will drift in the prevailing winds and the instruments, may, therefore, land at points as distant as about 200 to 350 kms from Hyderabad. The balloon drifts will be on the Vishakapatnam-Hyderabad-Sholapur line, in the areas of AP, North Karnataka and Maharashtra States.

The expected regions of impact of the payload after release from the balloon are: Hyderabad, Ranga Reddy, Medak, Mahboobnagar, Nalgonda, Warangal, Khammam, Nizamabad, Karimnagar and Adilabad districts of Telangana. The parachute with the instruments suspended underneath it, on a long rope, about 20 to 40 meters in length, will usually come down to ground quite slowly.

Scientist-in-charge, TIFR, Sunil Kumar appealed the peopleA�that those who find theA�parachute and instruments are requested not to remove them from its place of landing and to telephone or send a telegram to the address which will be given on various packages.

Those who find the parachute and instruments are also requested to contact the nearest police station, post office and district authorities about the finding.

On receipt of information from finders, scientists carrying out these experiments will collect the instruments and pay the finder a suitableA�rewardA�and also all other reasonable expenses for making telephone calls among others.

No reward will be paid if it is found that anything has been opened or tampered with. Kumar also requested the people to co-operate in this regard.
