Mercury's surface can reach a blistering 800 degrees Fahrenheit (430 degrees Celsius) during the day, according to NASA. But the planet lacks an atmosphere to hold that heat in — so, on Mercury ...

Credit: ESA/BepiColombo/MTM Plus, the situation doesn’t get any easier once you’re near Mercury. There’s no atmosphere to help a spacecraft slow down like there is at Venus or Mars.

How hot is Mercury? Mercury's sun-facing side is scorched by temperatures of around 430°C, hot enough to melt lead. Without a substantial atmosphere to distribute heat away from the areas facing the ...

Those ions continuously strip Mercury's atmosphere, but Mercury has a way to keep regenerating that atmosphere with material from its own surface. Finally, Mercury, despite being in the hottest ...

The two orbiters will collaborate to investigate Mercury’s origin and evolution and its internal structure, geological features, composition, and craters. They will also study its atmosphere ...

The University of Bern is the project leader for two instruments on board the ESA orbiter: a mass spectrometer called 'Strofio', which will analyse Mercury's atmosphere, and a laser altimeter ...

In particular, mercury is known to spread to distant areas through the atmosphere. An international research team has revealed for the first time the role of the stratosphere in the dispersion of ...
