A joint Russian-European mission to send a rover to Mars has been postponed by two years because its final phase has been compromised by the coronavirus outbreak in Europe.
The launch of the second ExoMars mission was initially planned for July or August of this year. But the two space agencies said they were now postponing its launch until a date between August and October 2022.
The mission plans to place a rover vehicle, the Rosalind Franklin, on the surface of the red planet to help scour it for signs of past life.
The extreme heat on the planet Mercury likely helps make ice on its polar regions, according to a study.
The researchers said while asteroids may have delivered most of Mercury's water, the planet's extreme daytime heat, combining with its ultracold polar craters could also be acting as an "ice-making chemistry lab".
According to the scientists, minerals in Mercury's surface soil contain what are called hydroxyl groups (OH), which are generated mainly by the subatomic particles protons.
Extreme heat helps to free up these hydroxyl groups, energise them to smash into each other, and produce water molecules and hydrogen.
