“It was a very quiet launch countdown, it went off like clockwork,” NASA Launch Director Omar Baez said. “Parker Solar Probe has been one of our most challenging missions to date.”<\/p><\/blockquote>\n
About four minutes into flight, the Delta IV port and starboard booster engines shut down and separated from the second stage. After second stage engine ignition, the payload fairing also was jettisoned. The second stage main engine cut off and separated.<\/p>\n
Shortly afterward, mission managers confirmed that the spacecraft’s solar arrays successfully deployed. The spacecraft, provided by Northrup Grumman, was operating on its own power.<\/p>\n
Carried by a United Launch Alliance Delta IV Heavy rocket, Parker lifted off from Cape Canaveral\u2019s Space Launch Complex 37. The launch had intially been scheduled for early Saturday, but last-minute technical glitches ate away at the launch window, prompting a 24-hour delay.<\/p>\n
The $1.5 billion mission will take humanity closer to the Sun than ever before. Parker will be the first spacecraft to fly through the Sun\u2019s corona, the outermost part of the star\u2019s atmosphere. It is expected to reach the Sun in November.
\nParker will face \u201cbrutal\u201d heat and radiation during an epic journey that will take it seven times closer than the previous closest spacecraft, Helios 2, in 1976<\/p>\n
Parker must withstand heat of nearly 2,500 degrees Fahrenheit to complete its audacious mission. To achieve this, the probe will be protected by a special 4.5-inch-thick carbon-composite shield. Safe inside the spacecraft, however, the probe\u2019s payload will be operating at room temperature.<\/p>\n
Harnessing Venus\u2019 gravity, Parker will complete seven flybys over seven years to gradually bring its orbit closer to the Sun. On its closest approach in 2024, the probe will be traveling at approximately 430,000 mph, setting a new speed record for a manmade object.<\/p>\n
The Sun\u2019s corona, which can be seen during a total solar eclipse, is usually hidden by the bright light of the star\u2019s surface. The probe, named after pioneering solar physicist Dr. Eugene Parker, will provide a wealth of invaluable data.
\nScientists expect to shed new light on the Sun\u2019s potential to disrupt satellites and spacecraft, as well as electronics and communications on Earth.<\/p>\n
Instruments on board Parker will study magnetic fields, plasma and energetic particles as well as imaging solar wind, a flow of ionized gases that stream past the Earth at more than a million miles an hour.<\/p>\n
Eugene Parker first theorized the existence of the solar wind. To honor his contribution to science, the probe is NASA\u2019s first spacecraft to be named after a living person.<\/p><\/blockquote>\n
The probe, which was designed and built by the Applied Physics Laboratory at Johns Hopkins University, is also carrying more than 1.1 million names to the Sun. In March, members of the public were invited to be a part in the historic mission by submitting their names to be placed on a memory card that the spacecraft will take into space. In May, NASA confirmed that, over a seven-week period a total of 1,137,202 names were submitted.<\/p>\n
Parker Solar Probe is the fourth mission this year for NASA’s Launch Services Program, which is responsible for launch service acquisition, integration, analysis and launch management for each mission. It\u2019s good to be back.<\/p>\n","protected":false},"excerpt":{"rendered":"
