Akatsuki Venus Climate Orbiter Options

[Paolo]

I thought it was time to start a separate thread on this mission, launching soon
some good medium-resolution images of the spacecraft are available on JAXA digital archives

• Mid infra red camera（LIR）： Functioning properly.

Already near normal, successive image capturing has been conducted and exceptionally interesting hitherto unreported phenomena
were discovered.

That is tantalizing. Thanks for all this hard work, P.

Unevenness is emphasized on the image

Wind velocities are estimated from cloud movement

・ possible to map wind distrbution at 60km altitude
・ possible to map wind distrbution at different altitudes using different wave lenghts
・ It is expected that we will be able to see where the super rotation is started

Night side raw image (right) at 1.01 mm
44,000km on 21 December 2016
Right underneath Akatsuki at +30 lattitude and +670 longtitude

・ Terrain is mainly visible
・ It is hope that we will be able to find mineral composition at ground surface
・ Continous observation is hoped to lead to information on the interiod of Venus

lattitude

(comments below the right hand side image)

Dark spot lower left is the Aphrodite continent
It is dark because this spot is 4km higher than surrounding areas and colder by 30K, resulting in smaller thermal radiation

Thank you so much pandaneko

Been waiting for your translation of Page-15.
Beautiful image.

What a wonderful mission.
