NASA will, on Sunday have another go at launching their historic unmanned Parker Solar Probe.
The probe will be 3.9 million miles from the sun's surface, making it the closest spacecraft to the sun's surface in history.
The launch had been due to take place yesterday but was dramatically aborted just seconds from lift-off after a last minute technical hitch.
The probe is protected by heat shields capable of withstanding temperatures up to 2500 degrees Fahrenheit, and it will complete 24 orbits of the sun by 2025, reaching speeds up to 430,000 miles per hour.
Scientists are aiming to use the probe to collect data about the inner workings of the highly magnetised corona, to better understand the causes of solar wind.
NASA on Sunday launched its ambitious Parker Solar Probe a day later than it was scheduled to after multiple checks exhausted the launch window.
Back in 1958, when the 31-year-old Parker suggested that the charged particles streamed continuously from the Sun and fill up the space, the scientific community refused to believe him.
"The sun is full of mysteries", said Nicky Fox, project scientist at the Johns Hopkins University Applied Physics Lab. Seven Venus flybys are planned over the seven-year mission to fine-tune the trajectory, setting up the close-in aim points.
The probe is the first NASA spacecraft with a living namesake.
"I really have to turn from biting my nails in getting it launched, to thinking about all the interesting things which I don't know yet and which will be made clear, I assume, over the next five or six or seven years", Parker said on NASA TV. Each flyby will provide an orbit-shaping gravity boost, drawing it ever closer to the sun and straight into the corona - the sun's outermost atmosphere.
Zurbuchen also described the probe as one of NASA's most "strategically important" missions.
Instruments on board may also help to explain why the corona is hotter than the sun's surface by several orders of magnitude. All I can say is: "'Wow, here we go.' We're in for some learning over the next seven years".
"Chandra, as he was popularly known, is another astrophysicist with his name tagged to a space mission, NASA's Chandra X-ray Observatory", Nandi said.
It is protected by an ultra-powerful heat shield that can endure unprecedented levels of heat, and radiation 500 times that experienced on Earth.
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.
