Scientists at the space agency were due to launch the probe yesterday - but it was called off due to "gaseous helium red pressure alarm".
The probe is the first NASA spacecraft with a living namesake.
"We've been inside the orbit of Mercury and done incredible things, but until you go and touch the sun, you can't answer these questions", Nicola Fox, mission project scientist, told CNN.
Mankind's first mission to "touch" the Sun may have panned out differently had it not been for Indian-American astrophysicist Subrahmanyan Chandrasekhar, whose intervention made it possible for a research paper proposing the existence of solar wind to get published 60 years ago.
Nasa has launched a probe that will head closer to the sun than any other spacecraft before it.
Running 24 hours late because of a last-minute countdown glitch Saturday, the trek began at 3:31 a.m. EDT (GMT-4) Sunday when the 233-foot-tall Delta's three hydrogen-fueled Aerojet-Rocketdyne RS-68A main engines ignited with a rush of brilliant orange flame and quickly throttled up to 2.1 million pounds of thrust.
The Parker Solar Probe carries a lineup of instruments to study the Sun both remotely and in situ, or directly.
It is travelling on board the Delta-IV Heavy rocket, which will hurl the probe into the inner Solar System. Parker watched the launch at Cape Canaveral and said it was his first time seeing a rocket blast off in person.
"All I can say is "Wow, here we go, we're in for some learning over the next several years", he said when asked how he felt.
Of course, the spacecraft won't actually touch the sun - its temperature is a ludicrously toasty 5,500 degrees Celcius, and would instantly destroy any probe.
"We are going to be in an area that is so exciting, where solar wind - we believe - will be accelerating", said NASA planetary science division director Jim Green.
At those speeds, the spacecraft will reach the sun by November, and scientists hope to have early data back from the probe by the end of the year.
Zurbuchen also described the probe as one of NASA's most "strategically important" missions.
One of the reasons, scientists are sending the probe is the Sun's atmosphere and the weird property it exhibits, of being hotter than the surface of the sun itself.
The heat shield is built to withstand radiation equivalent to up to about 500 times the Sun's radiation on Earth.
Yanping Guo, who designed the mission trajectory, said: "The launch energy to reach the Sun is 55 times that required to get to Mars, and two times that needed to get to Pluto". His 1958 paper was initially ridiculed but has come to be central to our understanding of the solar system and beyond.
The camera will also alert you to any imperfections in your shot, like if it's too blurry or if someone blinked at the wrong time. Samsung announced that the game will be available on its new Note 9 smartphone today during an event announcing that smartphone.
Firstly, the Note 9 ships with a new and improved S Pen , which comes with Bluetooth LE (Low Energy) baked-in for the first time. Looking for something a bit simpler? However, it wasn't initially available on phones running the Android operating system.
Adding the 5G capability with an accessory should make the transition cheaper, as it negates the need to buy a new phone. It'll be for Verizon's 5G network , and it will come "early in 2019", according to Verizon network chief Nicola Palmer.
The agents can cover minimal costs, such as meals and travel expenses related to gauging interest in professional opportunities. Agents will have at least a limited place within the NCAA structure when it comes to college basketball.
The Department will build a legislative proposal for congressional consideration as a part of the Fiscal Year 2020 budget cycle. But Mattis signaled earlier this week that establishing a combatant command was a possibility.
Ferguson, who has been involved from the start in the Starliner's development, flew three shuttle missions as a NASA astronaut. Josh Cassada: Coming to NASA after a career as a test pilot in the Navy, Cassada was chosen as an astronaut in 2013.
The joint statement released after the event, however, was vague at best and provided no clear pathway for Kim to do so. North Korea has chafed at USA insistence that no sanctions be eased until Pyongyang's disarms its nuclear weapons.
On if Meyer gets fired: "I would be heartbroken for Ohio State, for the players, for him and his family because it's not right". Coming from somebody who knows. "It's as heartfelt, honest and as true a statement as I've ever heard", he said.
The administration's assertion that lighter, more fuel efficient cars are more risky has been disputed by transport experts. At the same time, it plans to block California from putting its own mileage standards into place.
What a game! In a contest that had a little bit of everything, the Carolina Panthers defeated the Buffalo Bills by a 28-23 margin. Neither will get the opportunity to hash things out since the two teams do not face each other in the upcoming season.
He revealed: "If Meghan had much more makeup on, her face would have been the focus and not the gracefulness of her dress". It's clear that Meghan really is closing the chapter of her acting career and starting fresh on a new journey.
Don't forget to share this post on your Facebook wall and with your Twitter followers! I've heard a few other names as well. The service will not, however, carry the volume of content found on Netflix , Iger added.
Whitmer wins Democratic nomination for MI governor
Schuette has long fashioned himself after Trump, and he soared in polling once receiving the endorsement of the president. Gretchen Whitmer, left, won Michigan's Democratic nomination for the state's gubernatorial primary on Tuesday night.
A look at California's largest wildfires, by the numbers
It killed two people, including a firefighter, and destroyed more than 1,000 buildings before being fully contained on January 12. That can range from anything from a spark from a vehicle that catches fire in dry brush nearby, to, in extreme cases, arson.
Toll from worst S.W. Florida red tide in decade grows
As part of the directive, the conservation commission will assist local efforts to save animals affected by red tide. Most algae blooms are beneficial to the ocean, providing a source of food for marine creatures.
