Solar energy, Venus waves, and thermal maps of asteroids

12 July 2014

At http://phys.org/print324263317.html … a NASA funded mission to study the Sun's energy output. Solar irradiance changes over the Sun's 11 year cycle and probably changes over longer periods of time as well. The launch takes place on Monday 14th July.

At http://phys.org/print324203307.html … why does Venus' atmosphere rotate 60 times faster than its surface – 60 times. The planet Venus rotates slowly – but its atmosphere does not. The origin and mechanism of this is completely unknown – but waves in the atmosphere have been detected. Not only that but winds on Venus reach velocities higher than 400km an hour – which is 70 times faster than the planet rotates. Saturn's moon Ttan also has a super rotating atmosphere.

At http://phys.org/print324194220.html … a British designed asteroid mapper has been sent int orbit. It is capable of creating thermal maps of asteroids, even producing details on how their trajectories may change if on a near collision course with the Earth.
