About the Launch
The greatest origin story of all unfolds with the James Webb Space Telescope. Webb is NASA’s newest premier space science observatory – destined to be a household name, like its predecessor, Hubble. This is an Apollo moment for NASA science: Webb will fundamentally alter our understanding of the universe. It can observe all of the cosmos, from planets to stars to nebulae to galaxies and beyond – helping scientists uncover secrets of the distant universe as well as exoplanets closer to home. Webb can explore our own solar system’s residents with exquisite new detail and search for faint signals from the first galaxies ever made. From new forming stars to devouring black holes, Webb will reveal all this and more.
The launch readiness date for the James Webb Space Telescope is moving to no earlier than December 22 to allow for additional testing of the observatory. Webb was previously scheduled to launch December 18 on an Arianespace Ariane 5 rocket from Kourou, French Guiana.
