NASA's Roman Space Telescope Expected to Operate for 22 Years

<p>NASA's Nancy Grace Roman Space Telescope is on a precise trajectory toward its observation post, with engineers estimating that the spacecraft's fuel will last twice as long as initially expected, according to a statement from the space agency on Monday.</p><p>The $4.3 billion observatory was originally designed with enough propellant for a minimum operational lifetime of five years, with the possibility of a five-year extension. This estimate was considered conservative. NASA officials anticipated that a successful launch and effective execution of the telescope's first course correction maneuver would result in a significant fuel reserve.</p><p>Jamie Dunn, center director at NASA's Goddard Space Flight Center, stated, "As a result of exquisite planning by our orbital dynamics team, brilliant execution by the operations team, and a precise launch from SpaceX, Roman has fuel for at least 22 years of potential science operations."</p>
