ESA Science & Technology - Solar System
Fifteen years ago today, ESA's Huygens probe made history when it descended to the surface of Saturn's moon Titan and became the first probe to successfully land on another world in the outer Solar System. However, during its descent, the probe began spinning the wrong way – and recent tests now reveal why.
The NASA/ESA Hubble Space Telescope has once again captured comet 2I/Borisov streaking through our Solar System on its way back into interstellar space. At a breathtaking speed of over 175 000 kilometres per hour, Borisov is one of the fastest comets ever seen.
Data from ESA's Cluster mission has provided a recording of the eerie 'song' that Earth sings when it is hit by a solar storm.
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 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.
