Big science from small spacecraft
.... If we could position a radio telescope up at geostationary orbit (GEO) or higher, well above the ionosphere, we could observe and characterise these short-lived phenomena, a long-standing goal of the solar physics community. ...

Exploring Jupiter’s icy moons
... the three-dimensional properties of the magnetodisc and in-depth study of the coupling processes within the magnetosphere, ionosphere and thermosphere. Aurora and radio emissions will be elucidated. Within Jupiter’s satellite system, JUICE will also...

Future Cubesat swarms pose significant communications challenges
...and HiDEF missions were proposed in NASA’s 2009 Heliophysics missions to study small scale plasma physics in the ionosphere/thermosphere. The ARMADA mission proposes a swarm of 20 to 100 spacecraft in pseudo-random orbits featuring GPS receivers with...

Solar superstorms and their effects on Earth
...) identified several critical steps to improve its short and long-term forecasting capability of geomagnetic storms and ionospheric disturbance, some of which have now taken place. They include securing a dedicated, operational solar-wind monitoring...

Not stars, but 25,000 supermassive black holes!
...metres in length. Observing the sky at long radio wavelengths is complicated. For starters, free electrons in the Earth’s ionosphere act like a cloudy lens that constantly moves across the radio telescope, making observations difficult. ‘It's similar...
