If you are an advanced amateur astronomer and want to contribute to the Venus Express mission, prepare your telescope and look at the sky for the Morning Star.
Your images and data taken from the ground will complement the spacecraft's observations from Venusian orbit.
The Venus Amateur Observing Project (VAOP) is aimed at obtaining high-quality images of Venus before, during and after the Venus Express operations, which started in May 2006.
The ground observations campaign includes obtaining routine images of Venus during each appearance and co-ordinated observations during specific moments of the mission to provide simultaneous or data complementary to the spacecraft observations.
