Is the asteroid Psyche really a hunk of mostly metal? Is the object, which is nearly as wide as Massachusetts, the core of a baby planet whose rocky outer layers were knocked off during a cataclysmic collision in the early days of the solar system? Right now, all that astronomers can say is maybe, maybe not. NASA launched a spacecraft on Friday morning, also named Psyche, on a journey to the asteroid belt between Mars and Jupiter to find out. From a report: “We’re really going to see a kind of new object, which means that a lot of our ideas are going to be proven wrong,” said Lindy Elkins-Tanton, a professor of earth and space exploration at Arizona State University who serves as the mission’s principal investigator.
Being proven wrong, she added, “is, I think, the most exciting thing in science.” That voyage in search of answers kicked off Friday at 10:19 a.m. Eastern time. Falcon Heavy, the largest of SpaceX’s operational rockets, lifted off from Kennedy Space Center in Florida, sending the massive spacecraft on a journey that will last about six years and travel billions of miles. Friday’s flight overcame early, unfavorable weather forecasts for a seemingly flawless flight. About eight minutes into the flight, the rocket’s upper stage entered a 45-minute coasting period during which it will prepare to deploy the spacecraft on its flight away from Earth. The asteroid named Psyche has long been a curious enigma. Spotted in 1852 by Annibale de Gasparis, an Italian astronomer, it is named for the Greek goddess of the soul, and it was just the 16th asteroid to be discovered. In the early observations, it was, like the other asteroids, a starlike point of light that moved in an orbit around the sun, and not much more.
