NASA to Launch Artificial Star to Enhance Precision in Astronomical Research

NASA is preparing to launch an artificial star into space, a mission aimed at answering some of universe’s most profound mysteries. Led by researchers at George Mason University, $19.5 million project will help scientists calibrate telescopes and measure stellar brightness with greater precision. Named after astronomer Arlo Landolt, who was instrumental in cataloging stellar brightness, this mission marks a significant leap in astrophysical research.

Mission Aims to Revolutionize Space Observation  

artificial star, set to launch by 2029, will serve as a reference point for ground-based telescopes. Its precisely calibrated photon emissions will be measured alongside real stars, improving our understanding of stellar evolution and helping to determine rate at which universe is expanding. With aid of eight lasers, satellite will transmit beams to telescopes, allowing astronomers to fine-tune ir instruments for better data collection.

"This mission focuses on measuring fundamental properties essential to astronomical observations," said Eli Peretz, NASA Goddard mission and instrument scientist, and deputy principal investigator of mission. “It may change way we understand properties of stars, ir surface temperatures, and habitability of exoplanets.”

artificial star will orbit 22,236 miles above Earth, appearing stationary to telescopes due to its synchronized speed with Earth’s rotation. While invisible to naked eye, star will be visible through private telescopes, providing a crucial tool for astronomers to enhance accuracy of ir observations.
