Paris, Dec 19 : With Venus Express making the first detection of an atmospheric loss process on the planet's day-side, scientists have come closer to understanding where did all the water on Venus vanished, which is suspected to have once been as abundant as on Earth.
The spacecraft's magnetometer instrument (MAG) detected the unmistakable signature of hydrogen gas being stripped from the day-side.
"This is a process that was believed to be happening at Venus but this is the first time we measured it," said Magda Delva, Austrian Academy of Sciences, Graz, who leads the investigation.
