Mission to VENUS to scan whether Earth’s ‘evil twin’ once ever had water is announced by ESA


THE EUROPEAN Space Agency has revealed it will be sending a probe called EnVision to study the planet Venus.

This announcement comes one week after Nasa revealed it will be sending its Veritas and Davinci+ probes towards the second planet from the Sun.

The trio will work together to make the most of the missions.

Launches could begin at the end of this decade.

EnVision is expected to arrive at Venus in 2034 or 2035.

Venus is often described as Earth’s “evil twin” because it’s rocky and a very similar size to Earth but also extremely hot and dry.

The three missions will aim to answer why the planet differs so much from our own.

According to the BBC, Dr Colin Wilson, who help scope Envision, said: “Venus is our nearest neighbour and the only Earth-sized planet we can visit.

“It’s geologically active, we think. And if that’s the case we want to know why Venus didn’t turn out like Earth?

“Or, perhaps, the even better question is: why didn’t Earth develop like Venus? How come we got the habitable climate?”

EnVision will be focussed on the nature of Venus.

Nasa’s missions will be making maps and looking for evidence of geological activity like volcanoes.

EnVision will study the composition of rock to try and work out if there was ever water on the planet.

It will focus on areas that are considered the equivalent of Earth’s continents.

They’re called “tesserae” and EnVision could work out whether they were ever separated by water.

Previous missions suggest there are hundreds of thousands of volcanoes on the planet but we don’t know how many are still active today.

The budget for the mission is around €550million (£470million).

Interest in Venus has spiked recently after a study detected phosphine gas in its clouds and said this could be a sign of microbial life.

Venus – what you need to know

Here's what you need to know…

  • Venus is so hot that the surface temperature can reach 471 °C
  • It rotates in the opposition direction to most planets, potentially due to an asteroid collision
  • The first man-made aircraft landed on Venus in 1996
  • Venus is the hottest planet in the Solar System
  • It is the second brightest object in the sky at night
