Deep Space Fleet Telemetry

JWST is humanity’s premier infrared space observatory. Featuring a 6.5-meter gold-coated beryllium primary mirror and a 5-layer tennis-court-sized sunshield, Webb operates at cryogenic temperatures (~40 K) in an orbit around Sun-Earth L2. Its instruments resolve the earliest stars and galaxies formed after the Big Bang, map exoplanet transmission spectra, and peer through dense stellar nurseries.

Euclid is ESA’s space telescope designed to map the geometry of the dark Universe. Over six years, Euclid is imaging billions of galaxies across more than a third of the sky, measuring gravitational lensing distortions and baryon acoustic oscillations to understand the acceleration of cosmic expansion driven by dark energy.
