ESA Science & Technology - Solar System
Scientists analysing data from the Cassini mission have found evidence of light, soluble and reactive organic molecules in the ice grains ejected by Saturn's icy moon Enceladus, providing another important piece of evidence to investigate its potential habitability.
The NASA/ESA Hubble Space Telescope's Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away.
The assembly of the flight model of ESA's JUICE spacecraft began in September, with the delivery of the spacecraft's primary structure, followed by integration of the propulsion system that will enable the mission to reach and study Jupiter and its moons.
An important stage in the development of ESA's Solar Orbiter mission was completed between May and June, when a series of tests to validate the electromagnetic compatibility and magnetic properties was carried out on the spacecraft's flight model.
