The first ever spacecraft to fly directly toward the Sun is poised to blast off on Saturday, on a mission to plunge into our star’s sizzling atmosphere and unlock the mysteries of the centre of the solar system.
NASA’s car-sized, $1.5 billion Parker Solar Probe is scheduled to launch on a Delta IV Heavy rocket from Cape Canaveral, Florida during a 65-minute launch window that opens at 3:33 am (0733 GMT).
By coming closer to the Sun than any spacecraft in history, the unmanned probe’s main goal is to unveil the secrets of the corona, the unusual atmosphere around the Sun.
Launch countdown activities continue for this morning’s launch of Parker #SolarProbe. Liftoff is scheduled for 3:53am ET with a 95% chance of favorable weather. Watch: https://t.co/9uczz8fdI8 pic.twitter.com/vMkXQwZSsY
