en.Wedoany.com Reported - NASA's Nancy Grace Roman Space Telescope has completed its final checks and is ready for launch. This latest flagship-class telescope from NASA is scheduled to launch no earlier than August 30 from the Kennedy Space Center in Florida. After NASA announced the telescope's assembly completion in April, engineers conducted final inspections of the telescope's primary mirror. With this critical evaluation finished, the Roman team is preparing to transport the telescope to the Florida launch site.

"The Roman engineering team performed the last visual inspection of the telescope before it becomes humanity's eye on the universe," said J. Scott Smith, project manager for the Roman Space Telescope at NASA's Goddard Space Flight Center in Maryland, in a statement. "Witnessing the culmination of hard work from so many dedicated individuals, teams, and partner organizations is an extremely humbling moment."

The Roman telescope's primary mirror, measuring 7.9 feet (2.4 meters) in diameter, collects and focuses light from various celestial objects across the universe, making it critical to the telescope's ultimate success. "To achieve highly sensitive measurements of objects scattered across space, all components of Roman must meet ultra-high precision," said Bente Eegholm, optics lead for the Roman Optical Telescope Assembly at NASA Goddard, in the same statement. "The primary mirror has indeed achieved this precision."

Roman's pre-launch preparations included a "vibration test" designed to ensure the telescope can withstand the rocket launch and the space environment. The team had to confirm that this test did not displace any components. To verify this, they tracked the optical system along the path of light from the mirror to the telescope's primary scientific instrument—the Wide Field Instrument. "We developed a method using a high-resolution camera equipped with a high-magnification zoom lens for multipurpose inspections," Eegholm said. "The mirror performed excellently, keeping the mission on track for a launch in early September."

Although the telescope has been consistently scheduled for launch in early September, according to a report by Jeff Foust of SpaceNews, the telescope may be ready earlier, with a possible launch as early as August 30.
