ESA will launch its next space mission, Euclid, on 1R July. This unprecedented satellite, produced under the project management of Thales Alenia Space, aims to better understand the dark universe, i.e. dark matter and dark energy, whose true nature we know very little about. Euclid will launch on a SpaceX Falcon 9 launch vehicle at Cape Canaveral, Florida. Yes, Europe does not currently have the capability to launch its own satellites!
This weekend, SpaceX is expected to launch a Falcon 9 science satellite EuclidEuclid of the European Space Agency (ESAESA) for an amazing job. This unique satellite aims for excellenceuniverseuniverse Dark, that is Black materialBlack material and dark energy so little is known about their true nature.
For this, Euclid would make his observations from its orbit Lagrange point L2Lagrange point L2 of the Sun-Earth system, 1.5 million kilometers from Earth the sunthe sun, where the James-Webb Observatory is now located. It takes a month for the satellite to reach its final position. Euclid’s orbital period lasts eight months and takes 30 days to return to its final orbit. The beginning of scientific observations could begin in October 2023, with the first series of images that will help to stimulate public engagement and above all to test the capabilities of the satellite and its instruments. Euclid is scheduled to go live in April 2024.
The end of the task is plannedautumnautumn 2029 After six years of observation, there is a possibility to undertake an additional year.
Map the entire universe
” i’Dark energyDark energy and dark matter are manifested by the rather subtle changes which they bring to the appearance of objects in the visible universe; Otherwise we would not know their existence said project scientist René Laureijs. Euclid could see these effects more clearly than any other laboratory before him, on land or in space. For this, it uses two optical instruments, one imager observing inside the lightthe light A spectro-photometer in the visible and near InfraredInfraredTogether, it infers where dark matter might be hiding by mapping its effects on known objects.
Euclid maps the past 10 billion years of cosmic history over a third of the sky, from cosmic noon, when most stars formed, to the present day. This flashback will show us the variations in cosmic acceleration with pinpoint accuracy, reveal the nature of dark energy, and reveal the nature of dark matter.
did you know ?
An unknown source of “dark energy” seems to be driving our universe’s current rapid expansion, but scientists don’t understand how or why.
Five major mysteries that Euclid helps solve:
- What is the structure of the cosmic web;
- What is the story of the web;
- What is the nature of dark matter;
- how the expansion of the universe has evolved over time;
- Our understanding of GravityGravity Is that gross?
