In a groundbreaking endeavor that could unveil extraordinary answers to some of life’s most captivating inquiries, George Mason University has been entrusted to spearhead a pioneering NASA mission. The university located in Fairfax County, Virginia, has been tasked with constructing and launching an ingenious invention into orbit – an “artificial star.” This diminutive satellite will incorporate cutting-edge solar panels along with an array of lasers, enabling astronomers to observe it from terrestrial telescopes.
By monitoring the luminosity emitted by the lasers, scientists will achieve an unprecedented level of precision unparalleled in previous measurements. Peter Plavchan, an associate professor of physics and astronomy, explained that by comparing the brightness of celestial objects adjacent to the artificial star, they will attain a deeper comprehension of their luminosity. He will serve as the principal investigator for the $19.5 million Landolt NASA Space Mission, which aims to calibrate telescopes to more accurately gauge the brilliance of stars.
While the significance of this advancement may not be immediately apparent, Plavchan emphasized the potential it holds for research across multiple domains, including the momentous prospect of discovering another habitable planet. Over the past three decades, humanity has identified over 5,000 exoplanets orbiting distant stars. However, locating the elusive “Earth 2.0” or the fabled “Goldilocks planet” remains the ultimate objective. Plavchan explained that finding a planet with ideal conditions – the right temperature, size, mass, liquid water, and a compatible atmosphere – would establish the potential for extraterrestrial life.
The artificial star, inconspicuous to the naked eye, will orbit at an altitude of 22,236 miles, ensuring it orbits the Earth once every day while remaining fixed in the same section of the sky. With dimensions no larger than a shoebox, the spacecraft’s payload is slated for deployment in 2029.
Associate professor Piotr Pachowicz expressed his enthusiasm, stating, “This is an incredibly thrilling opportunity for George Mason and our students.” The university will be responsible for designing, constructing, and integrating the payload, a task that poses formidable challenges due to its installation in geostationary orbit.
The exciting collaboration between George Mason University and NASA ushers in an era of remarkable scientific exploration. By pushing the boundaries of our understanding of stellar luminosity, this mission endeavors to unlock the mysteries of the cosmos and perhaps herald the discovery of a new realm that could harbor life as we know it.
