NASA is inviting media to the Goddard Space Flight Center in Greenbelt, Maryland, on Tuesday, April 21, to view the newly completed Nancy Grace Roman Space Telescope, which is currently undergoing pre-launch testing. The event will include a press conference and represents one of the final opportunities for the public and press to see the observatory before it moves toward launch preparations.

The Nancy Grace Roman Space Telescope, often referred to simply as the Roman Space Telescope, is NASA's next flagship astrophysics mission. Designed to explore fundamental questions about dark energy, dark matter, and the formation of galaxies, Roman features a wide field of view roughly 100 times larger than that of the Hubble Space Telescope's infrared instrument, allowing it to survey vast regions of the sky in significantly less time.

The announcement, published in Spanish on NASA's official news release page, confirms that construction of the telescope has been completed and that engineers are now finalizing pre-launch testing procedures. No specific launch date was disclosed in the source material.

The Goddard Space Flight Center has served as the primary development and testing facility for the Roman telescope. Once launched, the observatory is expected to operate from the Sun-Earth L2 Lagrange point, the same orbital position used by the James Webb Space Telescope.
