During May 2016 the Earth and Mars get closer to each other than at any time in the last ten years, explained the ESA, in a statement.
This means that the Sun, Earth and Mars line up, with Earth sitting in between the Sun and the Red Planet, explained the ESA.
This event allows astronomers using telescopes in space and on the ground to see more details on the Martian surface, it explained.
The closest ever recorded oppositional approach was in 2003 when the red planet was 34.65 million away – its closest approach in 60,000 years.
Hubble s latest Mars image, which was taken with the telescope s Wide Field Camera 3 WFC3 will help astronomers study large-scale changes on the red planet s surface, scientists say.
The telescope recently helped astronomers find one of the largest-ever black holes in giant galaxy NGC 4889, some 300 million light years away.
