Solar Orbiter returns to Earth for a last goodbye (EN - NL - FR)

On 27 November 2021, the Solar Orbiter spacecraft returns from its voyages in deep space, and will pass at only a few hundred kilometers above the Earth's surface. This manoeuvre is needed to get Solar Orbiter in a new orbit to go yet closer to the Sun. During this flyby, Solar Orbiter unfortunately needs to cross the clouds of space junk that surround Earth, making it a risky visit to our planet.

The NANOK expedition

Two Belgian adventurers collaborate with STCE scientists during an untypical triathlon in Greenland in April 2022: 600 km with skis and a pulka, 1000 km sea kayaking and 1 km vertical rock ascent. Nanok is a polar bear in the Inuit culture.

EUI reveals campfires on the Sun

ESA made the first images and data of the instruments on board the spacecraft Solar Orbiter public. The telescope EUI, under Belgian lead, discovered campfires on the Sun.

EUI ready to observe the Sun, despite COVID-19!

May 12 is the day of the truth: the first image of the Sun taken by EUI onboard Solar Orbiter will come down. Will it be OK or not? The operations are led by the EUI team working from home. (NL/FR/EN)

The EUI Telescope is Waking up

The telescope Extreme Ultraviolet Imager (EUI), onboard of the Solar Orbiter spacecraft got a wake up call sent from ESOC, Darmstadt on February 25. At this stage, we can happily report that EUI is awake!


Launch of Solar Orbiter - Feb 10, 05:03 CET

NASA will launch the Solar Orbiter spacecraft from Cape Canaveral, with 10 scientific instruments on board, including the space telescope Extreme Ultraviolet Imager (EUI). Solar Orbiter will study the Sun from close up. The Royal Observatory of Belgium will manage the observations and coordinate the analysis of its unique solar images.

Happy birthday PROBA2!

On November 2, the ESA satellite PROBA2 will be celebrating its 10th anniversary. Not bad for this small Belgian spacecraft that was initially intended for a two-year mission!

EUI and Solar Orbiter ready for launch!

Brussels, 18 October 2019 – Ever closer to the Sun! The instrument EUI (Extreme Ultraviolet Imager) is integrated into the Solar Orbiter satellite to be launched towards the Sun in February 2020. Today, Solar Orbiter can be seen for the last time before being shipped to Cape Canaveral, the launch site.

Fourteenth European Space Weather Week

The European Space Weather Week (ESWW) is one of the main international conferences when it comes to space weather. Already for the 12th time, its organisation is in the hands of the STCE.
