James Webb Space Telescope

The James Webb Space Telescope is NASA's active flagship infrared space observatory, developed with ESA and CSA. After launch on Ariane 5 VA256, Webb deployed its sunshield and segmented mirror, entered a halo orbit around the Sun-Earth L2 point, completed commissioning, and began transformative observations of the early universe, star and planet formation, and exoplanet atmospheres.

Description
The James Webb Space Telescope is NASA's active flagship infrared space observatory, developed with ESA and CSA. After launch on Ariane 5 VA256, Webb deployed its sunshield and segmented mirror, entered a halo orbit around the Sun-Earth L2 point, completed commissioning, and began transformative observations of the early universe, star and planet formation, and exoplanet atmospheres.
Destination
Halo orbit around the Sun–Earth L2 point, approximately 1.5 million km from Earth, for infrared observations of the early universe, galaxy evolution, star and planet formation, and exoplanet atmospheres
Launch Site
Outcome
Successful and ongoing. Webb launched successfully, completed all major deployments, entered its planned Sun-Earth L2 halo orbit, achieved diffraction-limited optical alignment, completed commissioning, released its first full-color science observations, and remains operational.
