In the year of 1911, Hess’s meticulous experiments showed that the level of radiation decreased up to an altitude of about 1 km, but above that, the level increased considerably, with the radiation detected at 5 km being about twice that at sea level. He concluded that there was radiation penetrating the atmosphere from outer space, and his discovery was confirmed by Robert Andrews Millikan in 1925, who gave the radiation the name “cosmic rays.”
Ever since then, cosmic radiation has been a vast field of study, from its impact on spacecrafts to its effects on the human body.
On February 2, 2018, Sanket Deshpande, Lucky Kapoor, Shivangi Kamat, Vibhav Joshi and Pankaj Tiple of project Apeiro launched India’s first student-led microsatellite which will help in understanding cancer-causing cosmic radiation that constantly bombards the earth.
Apeiro was successfully launched at 2:12 a.m. on February 2 and achieved its first float altitude at 24.8 km. The second float altitude was achieved at 26.7 km.
This microsatellite was launched from the balloon facility of Tata Institute of Fundamental Research (TFIR) in Hyderabad.
The TIFR centre in Hyderabad is one of the few institutes in the world capable of launching such a flight.
