The balloon-borne telescope system for optical observation of planets

Our team is carrying out the project of Planet observation with high precision using balloon-borne telescope. The first model, BBT-1 was equipped with a three stage pointing system and an optical system to observe the detailed structure of the atmospheric motion of Venus. The first flight test was conducted in 2009, and the performance of the system was verified. However, because of a trouble of onboard computer, the flight operation could not been finished as planned. The second model “BBT-2” is now being developed and the next flight test is planned in 2011. The BBT-2 has a bus system including FPGAs and CPU, and it is expected to be more stable than the BBT-1.
