Japan's Akatsuki mission on Venus has been postponed due to bad weather. Bad weather at the spaceport of Tanegashima has prevented the probe from launching from that spaceport with its H-IIA rocket. The mission controllers were aiming to launch this rocket within early June for its six-month long journey to the space.

That H-IIA rocket is also going to deploy secondary satellites, with a big sail that will be propelled by sun light. Once the Akatsuki gets on to the mission and reaches the destination it will send reports on the atmosphere of Venus and look out for active volcanoes there. It will join the probe from the European Space Agency that arrived in 2006 on that planet.

Venus is very much similar in size to our planet but both are too far from each other. The temperature of the surface on the planet is about 460c due to a dense and large carbon dioxide atmosphere which acts as a blanket to trap the incoming solar radiation to heat the planet's surface. The surface pressure of Venus is about 90 times of the Earth's surface.
