This site is intended as a tool to share information, comments and schedules for preparing the 2010 coordinated campaign of ground-based observations in the context of Venus Express and coming launch of Akatsuki mission.
The attached Google docs can be completed and modified according to the campaign progress.
Map (under construction)
To have a general view of the sites and telescopes which are used for ground-based observations of Venus, see this googlemap for an overview for all of the different observatories and their instruments.
Coordination
To prepare the campaign and coordinate telescope proposals with VEx MTPs, the attached table is under construction. Please do not hesitate to comment/modify and add more details on your plans.

Akatsuki
- Goals: Akatsuki is designed to study Venus' climate using ultraviolet and infrared cameras. The spacecraft will follow orbit Venus following the westware rotation of the atmosphere, mapping the circulation and vertical structure of the planet's thick clouds. The mission will complement the ESA's Venus Express, which also explores the Venusian environment with different approaches.
- Accomplishments: This mission is in development.
