Brac Onnesha, the country's first nano-satellite developed by three Brac University students with the use of Japanese technology, began orbiting the earth yesterday. The joyous moment came when a robotic arm at the International Space Station (ISS) deployed the nanosat, a cube measuring 10cm along its edge and weighing around one kilogramme, into the orbit at an altitude of around 410km at 3:10pm Bangladesh time. Japan Aerospace Exploration Agency and Kyushu Institute of Technology (Kyutech) connected to the ISS in space and created opportunity for everyone on the Brac campus to see the event live. Taking 90 minutes to complete one orbit, Brac Onnesha would take high resolution photographs from which topographical data could be obtained, said Brac university officials. It would relay audio signals and be used for communications during emergencies via amateur "ham" radio equipment. It would also be able to measure atmospheric density before disintegrating on re-entry at the end of its six-month lifespan, they added.
