Endeavour (STS-31 mission)

STS-31 was a NASA space shuttle mission in April 1990 that launched the Hubble Space Telescope into Earth's orbit. The orbiter, Endeavour, carried the telescope, which is a large, advanced observatory that helps scientists study distant stars, galaxies, and the universe. The mission included deploying the telescope, which significantly expanded our understanding of space. The crew also performed spacewalks to set up and secure the telescope. This mission was crucial in making space-based astronomy more detailed and accessible, providing data for decades of scientific research.
