"Astronauts Repair NASA's NICER Telescope in Space"

NASA's NICER telescope, which has been affected by a "light leak" causing interference with X-ray measurements during the space station's daytime, is set to be repaired by astronauts during a spacewalk. The repair involves installing pie piece-shaped wedges to block out sunlight and mitigate the impact on observations. NICER, located near the space station's solar panels, collects data on cosmic phenomena and has contributed to numerous scientific papers. The telescope's repair is scheduled to launch later this year and is part of NASA's efforts to advance X-ray astronomy and space exploration.
