The Euclid mission will use either a Soyuz or an Ariane 62 launch vehicle from Europe’s Spaceport in French Guiana, with a launch timeframe starting in mid-2022. “With the goal of better understanding our Universe, launching this mission aboard an Ariane 62 or Soyuz is further proof of Arianespace’s ability to offer independent access to space for Europe’s ambitions,” Arianespace’s Chief Executive Officer Stephane Israel stated. 7 January 2020. It will be launched from a spaceport in French Guiana. The interior of this chamber is lined with black, cryogenically cooled shrouds to simulate the cold conditions that the spacecraft will experience once in space. The upcoming mission has been dubbed Euclid, named after the Greek mathematician and father of geometry Euclid of Alexandria. One important advantage of the STM is that, being a copy, it can be submitted to temperatures and mechanical stresses that are even more extreme than those expected in flight, therefore achieving qualification of the spacecraft design. For the mission, the ESA is planning to launch the satellite through the Ariane 62 vehicle or Soyuz spacecraft arranged by Arianespace. The temperature stability of the optical system is extremely stringent and must be maintained during operations, including the cases where the telescope has to change its pointing, resulting in a change in the solar illumination of the satellite. Together with its France-based commercial partner Arianespace, the ESA is targeting to launch the Euclid satellite sometime in 2022. During this test, the STM was installed inside a large thermal-vacuum chamber in Cannes. The Euclid satellite is scheduled for launch on a Soyuz rocket from Kourou, French Guiana, in June 2022. “Euclid will scrutinize the very nature of our Universe, shedding light on its dark side – the mysterious dark matter and dark energy – and building up on the great progresses made in cosmology over the past decades, which were recently recognized with a share in this year’s Physics Nobel Prize,” Gunther Hasinger, the ESA’s Director of Science, said in a statement. Heated plates simulated the radiation input that will occur on the spacecraft surfaces that will be exposed to the Sun in flight. NASA's Euclid Project Office is based at JPL. Aside from this, the satellite will also analyze the effect of dark matter on the growth and evolution of cosmic structures and objects. For the purposes of this section, the yearly tally of orbital launches by country assigns each flight to the country of origin of the rocket, not to the launch services provider or … Structural and thermal model of the Euclid satellite. The gravity of dark matter – which makes up the majority of matter in the Universe – causes tiny distortions of the images of distant galaxies via an effect known as gravitational lensing. The main objective of the satellite is to observe the universe’s expansion by studying dark energy and dark matter. In particular, key data are generated to characterise the insulation properties of the thermal multi-layer insulation blankets used to control the spacecraft temperature, as well as the effect of the heat generated by dissipating units, the heat rejection capability of radiators, and the performance of the heat pipes. Although most of the member scientists are from European countries, a team from NASA will also have the opportunity to study Euclid’s data. ESA selected Thales Alenia Space as mission prime contractor for the construction of the satellite and its Service Module, with Airbus Defence and Space chosen to develop the Payload Module, including the telescope.

The Euclid consortium, with important participation from NASA, will provide science instruments and data and science analysis. Arianespace and the European Space Agency (ESA) have announced the signature of a launch services contract for the Euclid satellite – with the mission’s timeframe for liftoff starting in mid-2022 from the Guiana Space Centre, Europe’s Spaceport in French Guiana, South America. To assess the impact of such variations, a satellite model was built which has nearly identical structural and thermal properties to those of the flight model – the actual spacecraft that will be launched into space.
