NASA’s Psyche spacecraft has blasted off and begun a six-year, 2.2-billion-mile journey to a peculiar asteroid. Astronomers have speculated that the space rock, also named Psyche, was once the partial core of a small planet in the early days of the Solar System. The seemingly iron- and nickel-rich asteroid may hold clues to the formation of planets, including our own.
On Friday, the uncrewed Psyche spacecraft lifted off at 10:19AM ET aboard a SpaceX Falcon Heavy rocket at Kennedy Space Center in Florida. After successfully jettisoning its fairings and separating from the rocket, ground controllers established two-way communication. Telemetry reports indicate it made it to space in good health. The mission had faced numerous delays before finally lifting off.
Psyche (the asteroid) rotates around the sun in a belt between the orbits of Mars and Jupiter. Researchers estimate it’s made of 30 to 60 percent nickel-iron core, allowing them a rare glimpse into a (possible) planetary core. “My best g
