Mars ionosphere shaped by crustal magnetic fields
Scattered pockets of magnetism across the surface of Mars have a significant influence on the planet’s upper atmosphere, according to observations from ESA’s Mars Express. Understanding these effects may be crucial for ensuring safe radio communications between Mars and Earth … Continue reading
MAVEN data solves Mars particle-beam puzzle
High above the surface of Mars’s sunlit side, protons of the solar wind begin to smash into the upper reaches of Mars’s atmosphere. NASA’s Mars Atmosphere and Volatile Evolution Mission (MAVEN) spacecraft, which arrived at the Red Planet in 2014, … Continue reading

MAVEN surveys the ionosphere of Mars
The ionosphere of Mars plays a critical role in the loss of atmospheric gases and water to space. MAVEN has provided the first measurements of the composition of the ionosphere of Mars since Viking in 1976. Unlike Viking, which provided … Continue reading
