NASA'a fastest spacecraft lifts off successfully after minor problems

NASA'a fastest spacecraft lifts off successfully after minor problems

The Mobile Service Tower is rolled back to reveal the United Launch Alliance Delta IV Heavy rocket with NASA's Parker Solar Probe on board at Cape Canaveral, Florida, US August 11, 2018.

Its closest approach will put it at just 3.8 million miles from the Sun, at which point it should be the fastest-ever human-made object with a speed of 430,000MPH. The incredibly resilient vessel, vaguely shaped like a lightbulb the size of a small auto, was launched early in the morning from Cape Canaveral Air Force Station in Florida. "Now, Parker Solar Probe is operating normally and on its way to begin a seven-year mission of extreme science".

NASA said the probe entered orbit around the Sun about 40 minutes after liftoff.

Parker Solar Probe will find out if its cutting edge heat shields will work - this death-defying spacecraft will fly daringly close to the sun - closer than any spacecraft before it. That may sound like a lot of distance, but the corona of the sun is hotter than the surface of the sun itself; its temperature is measured in the millions of degrees.

The $1.5 billion mission will perform the closest-ever observations of a star when it travels through the Sun's outer atmosphere, called the corona. The rocket's first stage consists of three main booster cores in a side-by-side configuration, each powered by a single Aerojet Rocketdyne RS-68A engine generating about 700,000 pounds of thrust, for a combined total of more than 2.1 million pounds of thrust.

Sunday's flight of his namesake mission was the first rocket launch Parker had seen in person, an experience he likened to seeing the Taj Mahal up close rather than in pictures or on TV. It wasn't until four years later, when a spacecraft bound for Venus found traces of energized particles streaming through space, that Parker's theory started to gain acceptance.

"All I can say is, 'wow, we are in for some learning for the next several years,"' he said during a post-launch interview on NASA TV.

This small instrument looking around the heat shield is a Faraday cup, and is a direct descendant of the first instrument to measure the existence of the supersonic solar wind expansion. These findings, in turn, could serve a practical goal by helping space agencies anticipate and protect against solar flares that can disrupt satellites and electrical grids on Earth.

In order to survive, the spacecraft folds its solar panels into the shadows of its protective solar shade, leaving just enough of the specially angled panels in sunlight to provide power closer to the sun.

"We've accomplished something that decades ago, lived exclusively in the realm of science fiction", he added, describing the probe as one of Nasa's "strategically important" missions.

The heat shield is made of a 4.5-inch thick carbon composite foam material between two carbon fiber face sheets.

NASA has successfully launched a historic and daring mission to the Sun to gather information about our closest star. The trick was making the spacecraft compact and light enough to travel at incredible speeds and durable enough to withstand the punishing environment.

"Our instrument pokes around the heat shield, looks directly at the sun... it really is just a cup, and particles just kinda flow into it and we catch them, and count how many of them there are".
