The mission

Cluster was a constellation of four spacecraft investigating the interaction between the Sun and Earth’s magnetosphere in unparalleled detail. The magnetosphere is our shield against the charged gas that carries particles and magnetic fields outwards from the Sun.


  • Launch: 16 July and 9 August 2000

  • Mission end: 8 September 2024

  • Observed: solar wind, magnetosphere

  • Orbit: elliptical around Earth’s poles, a few hundred to 125 000 km altitude

  • Spacecraft names: Rumba, Salsa, Samba and Tango

Euclid discovers the most ancient quasar in the Universe

The European Space Agency’s Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed in cosmic history. They shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age.

Successful Earth flyby improves Juice’s course to Jupiter

The European Space Agency’s Jupiter Icy Moons Explorer (Juice) skimmed the very outer edge of Earth’s atmosphere on 28 September, using the gravity of our home planet to alter its route to Jupiter using very little fuel.

Science begins for Smile

On 23 September, the European-Chinese Smile mission was declared ready to start revealing how Earth responds to the wind of charged particles from the Sun. This follows a busy in-space commissioning period since the spacecraft launched on 19 May and reached its target orbit for science operations on 20 June.

Cluster science highlights

Despite a nominal lifetime of two years, ESA’s Cluster is now entering its third decade in space. This unique four-spacecraft mission has been revealing the secrets of Earth’s magnetic environment since 2000 and, with 20 years of observations under its belt, is still enabling new discoveries as it explores our planet’s relationship with the Sun.
