NASA finishes deploying the James Webb Space Telescope
into service. The agency has successfully deployed the JWST's signature gold-coated primary mirror, completing all major deployments for the instrument. The mission crew still has to align the telescope's optics by moving the primary mirror's segments , but it's a strong sign the $10 billion device is in good shape.
The JWST also requires a third course correction burn as it heads toward the L2 Lagrange point between the Earth and the Sun. Astronomers will use the point to study infrared light without interference, potentially offering insights into the early Universe that aren't possibleFirst images from the telescope won't be available until the summer, and it could take much longer before those images translate to meaningful discoveries. Even so, the deployment is an achievement.
