Venus Investigations• Venus volcanism from emissivity mapping
at near infrared wavelengths, following Smrekar et al.
• Detection of optical signature of lightning• Investigation of the night side circulation of
the lower and middle cloud level• Investigation of the day side circulation of
Venus• Detection of airglow

Observations
• Imaging cube 1 – 2.5 µ @ ~ 0.1 arcsec• Multispectral imaging 270 – 1300 nm with
~ 50 nm resolution at selected ranges• Lightning Detection @ 773 nm•
