Nasa Prepares Parker Solar Probe To Fly, A Mission To Touch The Sun

Technicians and engineers perform light bar testing on NASA’s Parker Solar Probe, which will fly into Sun’s scorching atmosphere, in the Astrotech processing facility near NASA’s Kennedy Space Center, in Titusville, Florida, US, June 5, 2018.

On July 20, 2018, Nickola Fox, Parker Solar Probe’s project scientist at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland introduced Parker Solar Probe’s goals and the technology behind them at a televised press conference.

NASA is preparing to send the probe to touch the Sun than any other spacecraft has attempted, abiding horrible heat while zooming through the solar corona to study this outermost part of the earth’s crust that gives rise to the solar wind.

“The Sun’s energy is always flowing past our world,” said Fox. “And even though the solar wind is invisible, we can see it encircling the poles as the Aurora, which is beautiful – but reveals the enormous amount of energy and particles that diffuses into our atmosphere. We don’t have a strong understanding of the mechanisms that drive that wind toward us, and that’s what we’re heading out to discover.”

The Probe, a robotic spacecraft will light up with the launch on earlier than 6 Aug 2018 with a targeted planned seven-year mission. It is set to fly into the Sun’s corona within 3.8 million miles (6.1 million km) from the solar surface, seven times closer than any other space shuttle.

It has been placed with a heat shield designed to keep its instruments at a tolerable 29 degrees Celsius even as the spacecraft faces temperatures reaching nearly 2,500 degrees Fahrenheit (1,370 degrees Celsius) at its closest pass.

To send a probe where you haven’t been before being ambitious. To send it into such brutal conditions is highly ambitious,” Nicola Fox.
