Akatsuki :The Venus Climate Orbiter Akatsuki is a spacecraft developed in order to unravel the mysteries of the atmosphere on Venus. The spacecraft was launched from the Tanegashima Space Center on May 20, 2010 (UTC) and became the first Japanese probe to enter orbit around a planet other than the Earth on December 7, 2015.
Akatsuki/LIR :Long-wave infrared camera (LIR), on board Akatsuki. Infrared radiation of 10 micron wavelength is used to measure the temperature at the cloud tops. Two-dimensional temperature distribution at cloud tops can be used to investigate various types of waves and convection within the upper cloud layer, as well as wind speed distribution on the upper cloud tops of both dayside and nightside.
