EURECA Mission

EURECA was an ESA space environment exploration mission designed and developed to be recovered from orbit after completion of the mission and returned to Earth. The main objective of the recovery mission was the post-flight study of environmental effects (meteoroids and space debris impact) and wear-out mechanisms to the spacecraft and its payload.

EURECA was onboard the Atlantis Shuttle (STS-46), launched from Cape Canaveral, USA, on 31 July 1992. The EURECA payload was deployed from the shuttle cargo-bay on 2 August 1992 using the shuttle robotic arm. A burn raising EURECA’s orbit from 420 km to an operational altitude of 508 km was then performed, and the scientific mission began on 7 August 1992. Amongst the crew, was Claude Nicollier, the first Swiss astronaut on his first mission.

EURECA was retrieved by the Endeavour Shuttle during the STS-57 mission (21 June – 1 July 1993) using the Shuttle’s robotic arm, also referred to as Canadarm. EURECA was designed to fly five times with different experiments but the following flights were cancelled. In total. EURECA spent 11 months (336 days) in a sun-pointing orbit.

EURECA Instruments

Fifteen instruments were onboard EURECA amongst which was the SOVA (Solar Constant and Variability) experiment. SOVA was designed and manufactured by a consortium led by the Royal Observatory of Belgium, with PMOD/WRC as a sub-contractor.

EURECA and SOVA

After the return of the Endeavour space shuttle to Kennedy Space Center on 1 July 1993, EURECA spacecraft received a full inspection of the platform’s upper surface in the Orbiter Processing Facility. EURECA was subsequently transported to ESA facilities in Europe for further inspection.

In 2000, ESA donated EURECA to the Swiss Museum of Transport in Lucerne. EURECA is one of only several original space satellites to be displayed in a museum. In summer 2016, EURECA was taken to the Swiss Federal Laboratories for Materials Science and Technology (Empa) in Dübendorf near Zurich where X-ray scans of the satellite were taken. The goal was to find out how EURECA’s 11-month exposure to space had affected its structure and selected experiments it carried. EURECA was then returned to the Swiss Museum of Transport in Lucerne and has since been exhibited with both solar panels fully deployed for the first time.

After post-flight tests, SOVA was partly returned to PMOD/WRC during festivities to mark its 100th anniversary on 22 June 2007. Claude Nicollier, the first Swiss astronaut who participated during the shuttle mission to release EURECA in orbit, presented a signed copy of the SOVA flight model to the PMOD/WRC director, Werner Schmutz.
