If Mercury formed before the energy output from the Sun stabilised, it may have had twice the mass that it does now. Then when the Sun contracted and stabilised, massive temperature fluctuations vaporised some of the planet’s crust and mantle rock. Or a thinner mantle and crust may have always existed due to drag on the solar nebula (the Sun’s cloud of dust and gas from which the planets formed) from the close proximity to the Sun itself. Our latest information from the Messenger spacecraft supports the latter theory, because it has found high levels of materials like potassium on the surface, which would have been vaporised at the extreme temperatures needed for the former theory.
The Soviet spacecraft Venera-5 and Venera-6 attempted The Pioneer programme was designed specifically to study Venus landings in 1969, but were once again crushed by the pressure on the surface. In 1970, Venera-7 also made a landing and stayed in contact with the Earth for around 30 minutes. The Venera programme continued through Venera-16 in 1983, and it was integral in mapping the planet. NASA continued to send probes to fly by, including Mariner 10 on its way to Mercury in 1974, which took ultraviolet photos of the planet’s clouds and revealed its wind patterns.
As a result, they may take days to reach Earth, but when they do, the magnetic field still carried within them can interact with Earth’s own magnetism to cause major geomagnetic storms. 7 solar radii, where bulk movements of charged gas bring heat to the surface. Details of this mechanism, known as the solar dynamo, are not certain, but at the start of a cycle it is capable of generating a fairly orderly magnetic field whose poles roughly align to the Sun’s axis of rotation. Over time, though, the solar interior experiences ‘differential rotation’, with equatorial regions rotating faster than high latitudes.
