Parker Solar Probe is humanity's first-ever mission into a part of the Sun's atmosphere called the corona . It'll fly just over 6 million km from the surface - protected from the searing temperatures by a revolutionary new heat shield. But then, the launch of NASA's Mariner 2 spacecraft in 1962 - becoming the first robotic spacecraft to make a successful planetary encounter - proved them wrong.

Originally slated to fly in the small hours of Saturday morning, the Parker Solar Probe blasted off Sunday from Florida's Kennedy Space Center at 03:31 am EDT / 00:31 PT / 8.31 UMT. Nothing from Planet Earth has ever hit that kind of speed. "To me, it's still mind-blowing, " she said. The car-sized probe will utilise Venus to try and achieve an orbit around the sun by helping to slow it down.

The engineers are taking utmost caution with the $1.5 billion Parker Solar Probe, which Thomas Zurbuchen, head of Nasa's science mission directorate, described as one of the agency's most "strategically important missions". The last time a man-made object came close to the star's surface was in 1976 when Helios 2 achieved perihelion, the point of the orbit at which it was closest to the sun, at 27 million miles.

The race to save J50, a female with the potential to reproduce, is considered crucial for the endangered southern resident killer whale population that stands at just 75 whales.

Canadians will only be able to spot it early in the morning in Nunavut, but the rest of the country - and the entire USA - will be out of luck. Also, it turns dark during a solar eclipse as the Sun gets blocked.

NASA scientists also hope to answer one ongoing mystery: why the sun's atmosphere is 300 times hotter than the surface itself. The shield should enable the spacecraft to survive its close shave with the centre of our solar system, coming within 6.16 million kilometres of the Sun's surface.
