atmospheric gravity waves
Swansong experiment sheds light on Venus’ polar atmosphere
Some of the final results sent back by ESA’s Venus Express before it plummeted down through the planet’s atmosphere have revealed it to be rippling with atmospheric waves and, at an average temperature of -157 °C, colder than anywhere on Earth. The aerobraking experiment has improved our knowledge of our planetary neighbour and holds great promise for ESA’s forthcoming ExoMars mission.
Pluto’s atmospheric haze varies in brightness
Scientists on NASA’s New Horizons mission team are learning more about the structure and behaviour of Pluto’s complex atmosphere by discovering new attributes of its extensive haze layers. The hazes were first discovered by New Horizons in July 2015, as the spacecraft swept past Pluto and made its historic first exploration of the mysterious dwarf planet.
