The probe is created to plunge into the Sun's mysterious atmosphere, known as the corona, coming within 6.16 million kilometers of its surface during a seven-year mission.
Now 91, Professor Parker of the University of Chicago, the first living scientist to have a space probe named in his honour, flew to Cape Canaveral to witness his first rocket launch. "Parker Solar Probe would be just 4cm away from the Sun", explained Dr Nicky Fox, the British-born project scientist who is affiliated to the Johns Hopkins Applied Physics Laboratory.
Looking on at the launch was astrophysicist Eugene Parker, who first theorised the existence of the solar wind in 1958.
To reach its target, the Delta 4 Heavy and a solid-propellant upper stage had to supply enough energy to counteract Earth's 18-mile-per-second orbital velocity around the sun, allowing the spacecraft to fall into the inner solar system. Saturday morning's launch attempt was foiled by last-minute technical trouble.
A NASA spacecraft zoomed toward the sun Sunday on an unprecedented quest to get closer to our star than anything ever sent before. This followed earlier trouble in the countdown.
Altogether, the Parker probe will make 24 close approaches to our star during the seven-year, $1.5 billion journey.
"I have learnt a very important lesson of my professional scientific career from him: to be generous to the ideas of others, as long as they are not obviously wrong, and even if they contradict my own personal views", he said.

In a previous statement she said: "The Bat is out of the bag and I am beyond thrilled and honoured". "Thank you everyone. Rose went on to note that when women and minorities "tear each other down it's much more hurtful than from any group".
"This mission truly marks humanity's first visit to a star that will have implications not just here on Earth, but how we better understand our universe", said Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate.
NASA's Parker Solar Probe, which will fly closer to the Sun that any other spacecraft has attempted before is set to explore the corona, a region of the Sun only seen from Earth when the Moon blocks out the Sun's bright face during total solar eclipses.
If all works as planned, the inside of the spacecraft should stay at just 85 degrees Fahrenheit.
NASA has billed the mission as the first spacecraft to "touch the Sun".
A heat shield has been created to keep Parker's instruments at a tolerable 85 degrees Fahrenheit or 29 degrees Celsius.
Scientists have wanted to build a spacecraft like this for more than 60 years, but it was only in recent years that the heat shield technology advanced enough to be capable of protecting sensitive instruments.
Although the probe itself is about the size of a auto, a powerful rocket is needed to escape Earth's orbit, change direction and reach the sun. It could be due to interactions between electrically charged particles and the sun's powerful magnetic field, or it could be the result of countless "nanoflares" governed by another mechanism.
Stephens had dominated the first set, scoring two early breaks to race into a 4-0 lead against a hesitant Svitolina. His match over Zverev was most impressive as he was down 6-3, 5-2 and saved two mach points.
Harry is on a private working visit to Botswana with his charity Rhino Conservation, Kensington Palace confirmed last week. Speaking from his home in Mexico, Mr Markle said: "I don't expect to see her or hear back from her and that's OK".
It is powered by up to Intel 8 gen Core i5/i7/i9 and Xeon processor, 64 GB of DDR4-2667 RAM, 4TB SSD and NVIDIA Quadro P2000 GPU. The device weighs around 1.7kgs (that's 3.76lbs), which is pretty impressive considering all the power you are getting.
Rockstar clearly shows their intent to create more than gameplay and story, focusing equally upon immersion and realism. They'd shake it off but one can only imagine you could do the same with a horse or wagon in Red Dead Redemption 2 .
Rudd will also executive produce Living With Yourself with Anthony Bregman, Jeff Stern, Tony Hernandez, and Jeff Blitz. Other memorable TV appearances include Friends , Parks and Recreation and Reno 911 .
One reason for those lousy numbers is the surge in GOP retirements: 26-the highest number of GOP departures since 2006. But it was swell enough to make them the favourites to win the House of Representatives in the midterms.
Arsenal target Rabiot turns down new PSG contract offer
Substitute Weah, the son of former PSG forward and Liberia President George Weah, got his maiden league goal late in the match. PSG were without their World Cup winners - including Kylian Mbappe - for German manager Tuchel's first league game in charge.
Did red tide kill this 26-foot-long whale shark in Florida?
Fish populations generally bounce back after a Red Tide , but the toxic bloom is also wreaking havoc among more sensitive animals. That was the message from Kelli Levy, Environmental Management director, during an August 7 County Commission meeting.
