Akatsuki, also know as Venus Climate Orbiter (VCO) and Planet-C was launched on May 21st, 2010. In commemoration of 6th anniversary of the launch, IMV has received the letter of appreciation dated on May 20th 2016, thanking to our contribution to the development of Akatsuki project.

Using our electrodynamic vibration test system and an evaluation system for amount of inertia, we have evaluated and analyzed “Akatsuki (PLANET-C)”. Akatsuki is to study the the stratification of the atmosphere, atmospheric dynamics, and cloud physics by using five different cameras.
