            "description": "This illustration shows the relative scale of the Nancy Grace Roman Space Telescope and a Tyrannosaurus rex. Roman will be over 42 feet (12.7 meters) long — about the length of a T. rex — and over 14 feet (4.4 meters) wide when fully deployed. Roman will also weigh around 18,000 pounds, or 8,000 kilograms (dry mass) – which is the approximate mass of a Tyrannosaurus rex as well.\r\n\r\nCredit: NASA's Goddard Space Flight Center Conceptual Image Lab",
