3 Dec 2015Venus exploration past, present and future

Venus should be the Earth’s twin – similar in age, size and composition to the Earth – but its climate has gone seriously awry, with a runaway greenhouse effect which heats its surface to 450°C. How and why did Venus end up so different from the Earth?

A fascinating flotilla of spacecraft have visited Venus, including orbiters, short lived-landers and even balloons. ESA’s Venus Express, the only spacecraft to orbit Venus in the last two decades, has provided tantalising evidence of volcanic activity. Finally, a new raft of Venus missions is under consideration in Europe, America, Russia, and even China and India – we’ll consider what these may reveal.
