NASA Launches Probe to Study Rocky Asteroid
The U.S. space agency, NASA, launched a rocket Friday from the Kennedy Space Center in Florida. The rocket carried a probe designed to study a metal-rich asteroid that scientists think might be the remnants of small planet or planet-like object. The rocket, built by the private space company SpaceX, took off early Friday, starting NASAs Psyche probe on a 3.5-billion kilometer, six-year journey to the asteroid of the same name, orbiting between the planets Mars and Jupiter. Using Earth-based radar and optical telescope data, scientists hypothesize that the asteroid Psyche could be part of the metal-rich interior of a "planetesimal," a building block of a rocky planet that never formed. NASA scientists say Psyche may have collided with other large bodies during its early formation and lost its outer…
