"Euclid's Space Odyssey: Exploring the Infinite Halo"

The Euclid mission, launched by the European Space Agency (ESA), is headed to Lagrange point 2, a gravitational oasis located about 1.5 million kilometers from Earth. Lagrange points are created by the gravitational pull of two large bodies and allow spacecraft to orbit with minimal fuel. Euclid will spend six years studying dark matter and dark energy, which make up 95% of the universe. Despite its distance, Lagrange point 2 is considered an Earth orbit, and once the mission is over, Euclid will be directed into a heliocentric orbit to comply with international regulations on the sustainable use of space.
