Venus, meet Japan. Today the Japan Aerospace Exploration Agency (JAXA) launched a rocket carrying several different missions bound for our boiling-hot sister planet. Here's what they want to learn. Atmospheric Tag Team Akatsuki, the Venus climate probe, will arrive at the second planet from the sun in December. There it will team up with the European Space Agency's Venus Express probe, using five cameras to peer down into the turbulent atmosphere and study Venus' maniacal meteorology.
One of the main goals is to understand the "super-rotation" of the Venus atmosphere, where violent winds drive storms and clouds at speeds of more than 220 mph (360 kilometers per hour), 60 times faster than the planet itself rotates [MSNBC].
