The curious case of Earth's leaking atmosphere

Earth's atmosphere is leaking. Every day, around 90 tonnes of material escapes from our planet's upper atmosphere and streams out into space. Although missions such as ESA's Cluster fleet have long been investigating this ...

Saturn and Enceladus produce the same amount of plasma

The first evidence that Saturn's upper atmosphere may, when buffeted by the solar wind, emit the same total amount of mass per second into its magnetosphere as its moon, Enceladus, has been found by UCL scientists working ...

Cassini mission provides insight into Saturn

Scientists have found the first direct evidence for explosive releases of energy in Saturn's magnetic bubble using data from the Cassini spacecraft, a joint mission between NASA, the European Space Agency, and the Italian ...

A solar wind workhorse marks 20 years of science discoveries

The end of 2014 marks two decades of data from a NASA mission called Wind. Wind—along with 17 other missions – is part of what's called the Heliophysics Systems Observatory, a fleet of spacecraft dedicated to understanding ...

Cluster helps to model Earth's mysterious magnetosphere

For many years, scientists have been striving to understand the constantly changing structure and behaviour of the huge magnetic bubble that surrounds our planet. One approach – pioneered by Russian scientist Nikolai Tsyganenko ...

NASA's MMS observatories stacked for testing

(Phys.org) —Engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., accomplished another first. Using a large overhead crane, they mated two Magnetospheric Multiscale, or MMS, observatories – also called mini-stacks—at ...
