  "account": "NASA is set to launch its Roman Space Telescope on Sunday, embarking on a multiyear mission to create an unprecedented map of the cosmos. Designed to take a panoramic view of space, the telescope will help unlock the secrets of the universe. Standing over 12 meters tall, it is scheduled to launch from Florida aboard a SpaceX Falcon Heavy rocket at 7:26 a.m. (1126 GMT). Developed over a decade at a cost exceeding $4 billion, the telescope is named after pioneering astronomer Nancy Grace Roman, known as the \"Mother of Hubble.\"\n\nRoman will give Earth a new atlas of the universe, with a field of view 100 times larger than Hubble's. It will survey vast swaths of the sky from a distance of 1.5 million kilometers from Earth, taking about 100 days to reach. The telescope will work in tandem with other observatories like the James Webb Space Telescope, aiming to discover thousands of exoplanets and tens of thousands of supernovae. It will also shed light on dark matter and dark energy, which together make up about 95% of the universe.\n\nThe telescope's infrared vision allows it to detect light emitted by celestial objects billions of years ago, effectively looking back in time. This will help scientists understand these two mysterious phenomena and test their current model of the universe's expansion. Recent observations suggest the model may be incorrect. Scientists and the public will have access to all of the telescope's data, but the sheer volume will be challenging to handle.\n\nThe Roman Space Telescope is expected to generate about 1.3 terabytes of data a day, far beyond what can be downloaded to a laptop. However, the telescopes' observations are highly anticipated, as they could challenge scientists' understanding of the universe's structure and lead to new questions for future missions.",
  "summary": "NASA is preparing to launch its Nancy Grace Roman Space Telescope on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy Space Center in Florida. The launch is scheduled for Sunday, August 30, with the first launch window opening at 7:26 am EDT. According to NASA Science, several key milestones must be completed before liftoff, including propellant loading and final pre-launch checks.\n\nThe Roman Space Telescope is NASA's most ambitious scientific mission since the James Webb Space Telescope in 2021, as noted by Le Monde English. Once operational, it will conduct wide-field surveys of the universe, producing thousands of images each day. The telescope will study the nature of dark matter and dark energy, and it is expected to map billions of galaxies, discover exoplanets, and track the growth of structures over time.\n\nThe telescope, with a lifecycle cost of about $4.3 billion, according to Mashable, will be positioned at the second Sun-Earth Lagrange point, or L2, nearly 1 million miles from Earth. From this location, it will have a wide and relatively unobstructed view of the sky. The Indian Express reported that weather conditions are a concern, with a 50 percent chance of favourable launch conditions on Sunday.",
