Akatsuki - Venus Climate Orbiter

PLANET-C1-SM.jpgAkatsuki ("Dawn"), also known as the Venus Climate Orbiter (VCO) and Planet-C, is a Japanese Aerospace Exploration Agency (JAXA) probe tasked to study the complex atmosphere of Venus.

The scientific payload consists of six instruments. The five imaging cameras will explore Venus in wavelengths from ultraviolet to the mid-infrared.  By using these cameras, Akatsuki will study the stratification of the atmosphere, atmospheric dynamics, and cloud physics.

20151209_AKATSUKI_20151207_UVI.png Akatsuki's ultraviolet imager (UVI) sees shorter-wavelength ultraviolet than any other previous Venus imager, at 283 nanometers. Akatsuki took this photo on December 7, 2015 from a distance of 72,000 kilometers. 

20151209_AKATSUKI_20151207_LIR.jpg Akatsuki's longwave infrared imager (LIR) takes images at a wavelength of 10 microns, studying cloud-top temperatures. This is the first photo of its kind taken in Venus orbit. It was acquired by Akatsuki on December 7, 2015 from a distance of 72,000 kilometers.
