Students from a high school science club in the Gyeongnam region succeeded in taking pictures of the Earth by flying a balloon equipped with a camera into space.
According to Bunseong High School in Gimhae on the 31st of last month, 11 students from the science club ‘Air Craft’ released a 1,200g balloon filled with helium gas at a vacant lot in Sangbuk-myeon, Yangsan-si on the 5th of the same month.
Below the balloon, a camera, various sensors that check atmospheric pressure, ozone, and ultraviolet rays, and a GPS (positioning system) were attached to a Styrofoam box.
The balloon they flew flew for about 1 hour and 40 minutes before bursting안전놀이터 due to pressure.
Instructor Han Byeong-hyeon said, “Considering the gas pressure and the balloon’s rising speed, the balloon appears to have reached an altitude of 33 km, which is the stratosphere.” The camera in the balloon they flew clearly recorded Geoje-si and Namhae-gun in Gyeongsangnam-do and Tsushima Island (Tsushima Island) in Nagasaki Prefecture, Japan.
Teacher Han Byeong-hyun explained, “At the time of the flight, Typhoon ‘Kanun’ sucked air from the western part of the Korean Peninsula, and unlike usual, the wind blew from east to west, making the experiment successful.”
A teacher continued, “Thanks to calculations on the amount of helium gas and the relationship with the atmosphere, ascent and descent speeds, and GPS , we were able to predict the landing location,” and added, “Following the successful flight, finding the exploded balloon debris, including the camera, is a highly difficult project.” He said.
The debris was discovered in Mujeon-ri, Uiryeong-eup, Uiryeong-gun, Gyeongsangnam-do, about 100km away from the starting point. They succeeded in flying the balloon last year, but were unable to find any debris because they could not withstand the stratospheric temperature of -50 degrees Celsius.
