Housed inside a protective and environmentally controlled transportation container, NASA’s Nancy Grace Roman Space Telescope is secured in the usable cargo deck of the agency’s Pegasus barge as it arrives at the Launch Complex 39 turn basin at NASA’s Kennedy Space Center in Florida on Sunday, June 21, 2026. Teams will offload and transport the observatory to the spaceport’s Payload Hazardous Servicing Facility where it will undergo processing ahead of launch, targeted no earlier than Sunday, Aug. 30, 2026. Named for NASA’s first chief astronomer and “mother of the Hubble Space Telescope,” Roman will offer a field of view over 100 times larger than Hubble’s to study up to a billion galaxies, directly image exoplanets and planet forming disks, and address fundamental questions about dark energy, exoplanets, and infrared astrophysics.

Named for NASA’s first chief astronomer and “mother of the Hubble Space Telescope,” Roman will offer a field of view over 100 times larger than Hubble’s to study up to a billion galaxies, directly image exoplanets and planet forming disks, and address fundamental questions about dark energy, exoplanets, and infrared astrophysics.

In this aerial view, teams with Exploration Ground Systems (EGS) transport the agency’s powerful SLS (Space Launch System) core stage to the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Wednesday, July 24, 2024, after it completed the journey from NASA’s Michoud Assembly Facility in New Orleans aboard the Pegasus barge. In the coming months, SLS will be prepared for integration atop the mobile launcher ahead of the Artemis II launch.
