Heroes since ancient times. British 13-year-old Alexander Forsyth has recently teamed up with doctoral students at Newcastle University to launch a self-made simple satellite to collect solar radiation and atmospheric fluctuation data. Forsyth attended Bid College in Bryce, Northumberland. They tied some table tennis-sized solar sensors on a helium weather balloon and used it in the Blackrock Desert in Nevada. The balloon can fly to over 30,000 meters altitude. The sensor named Pong-sat collects solar radiation and atmospheric fluctuation data. After a while, the balloon burst, but the parachute protection sensor attached above landed safely on the ground. Forsythe et al. spent 5 days developing solar sensors, each with different tasks. Forsyth is waiting for data to return in order to study how solar panels work in space. The purpose of Forsyth is to calculate and compare the advantages and disadvantages of solar panels in the atmosphere and outer space. The British "Daily Mail" quoted him as saying: "Pong-sat contains microchips and sensors to measure the solar radiation flow, the volume can not be larger than the table tennis. My idea is that if you put solar panels in outer space , can get good light, but the accumulated power may be weakened due to temperature effects."
