[#insert3] Measurements of its gravity field tell us that the rock and metal sank to form a core about the size of our Moon, with a mantle and crust of ice floating above it. [#insert4] In addition, the Galileo spacecraft discovered that Ganymede has a magnetic field, the [#high...
Does Mars have a Magnetosphere? 喜欢 0 阅读量: 9 作者:Max,K.,Wallis 摘要: SummaryThe space-probe plasma and magnetic evidence for Mars having a significant dipole field is uncertain and contradictory. If ionization processes in the planet's exosphere are taken into account, several discrepancies...
In addition, the Galileo spacecraft discovered that Ganymede has a magnetic field, the signature of a partially molten interior. Ganymede is not a dead world, but rather a place of continuing geological activity powered by an internal heat source. Much of its surface may be as young as half...
Does Mars have extinct volcanoes? Features of Mars: Mars is a terrestrial planet that is about half the size of Earth. It is extremely cold, with an average temperature of about -80 degrees Fahrenheit. Scientists have learned much about its rocky surface since spacecraft first landed on it ...
