AKATSUKI has been performing test observation by turning on its onboard observation instruments one by one. The instruments are starting up normally, and we have already conducted successful observation that is equivalent to be a “minimum success”(*), thus we will move to the regular operation in mid April.
* Minimum success: The minimum goal for achieving a mission. For AKATSUKI, the minimum success is to capture Venus’s all-globe cloud structure by continuously acquiring image data (for every few hours) using some of its onboard cameras from Venus orbit.
Image: Test observation result by the Longwave IR camera (LIR) The image shows a bow-shape clouds running from the Southern hemisphere to the Northern one of Venus. This is the first time to learn such a phenomenon.
