That’s why NASA’s Planetary Defense Coordination Office monitors objects in space that could potentially harm the planet. With asteroids, there is almost always a possibility one can hit Earth. “These close approaches are precious opportunities to better investigate the smallest objects, which would be too faint if too distant,” he said. Near encounters like the GN1 asteroid flyby offer scientists a chance to learn more about the space rocks, Masi said. “Its orbit was known well enough to conclude for sure it was not going to hit us,” he said. Unlike Chelyabinsk, GN1 posed no risk to people, said Gianluca Masi, founder and scientific director of the Virtual Telescope Project. The asteroid blew up near Chelyabinsk, Russia, in 2013, creating a sonic boom that injured more than 1,000 people, Hankey said. GN1 is about the same size as the Chelyabinsk Meteor, which was 59 feet (18 meters) long, said Mike Hankey, operations manager at the American Meteor Society. NASA still hopes to launch moon mission in June despite two scrubbed trials In later missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars. Artemis I will be the first integrated test of the SLS and Orion spacecraft. The SLS and Orion atop the mobile launcher were transported to the pad on crawler-transporter 2 for a prelaunch test called a wet dress rehearsal. Blue sky and clouds serve as the backdrop for a sunrise view of the Artemis I Space Launch System (SLS) and Orion spacecraft at Launch Pad 39B at NASA's Kennedy Space Center in Florida on March 23, 2022.
