NASA plans robotic probe to Sun; wants to solve three important questions

Scientists have long wanted to send a probe through the sun's outer atmosphere, or corona, to better understand the solar wind and the material it carries into our solar system.

Solar Probe Plus is expected to liftoff during a 20-day window that opens July 31, 2018, according to NASA.

Further NASA scientists are also looking for an answer to the question of how is solar wind gets its speed. The space agency will be sending that spacecraft within four million miles of the sun in 2018, an incredibly close distance considering the fact that our Earth is 93 million miles away.

"Without advance warning a huge solar event could cause two trillion dollars in damage in the USA alone, and the eastern seaboard of the United States could be without power for a year", the Solar Probe Mission team informed. However, unlike Icarus, who plunged to his death when the sun melted his wings, we need to be very careful in our endeavor.

Flying to within 4 million miles of the sun is the challengeof how To deal with the extreme temperatures.

If all goes as planned, the Solar Probe Plus will be the closest that a man-made object has ever made it this close to the sun.

"You'd think the farther away you get from a heat source, you'd get colder", said Eric Christian, a researcher from NASA's Goddard Space Flight Center, according to Tech Times. "The Sun blows a stream of charged particles in all directions at a million miles an hour, but we don't understand how that gets accelerated", Christian stated.

Solar probe will take direct measurements from the near-Sun environment which will revolutionize our knowledge of coronal heating, the origin and evolution of the solar wind and occasional emission of high energy particles that are hazardous for spacecrafts and astronauts.

This Solar Plus Probe will also help the scientist to read out the space weather events which can have a great impact on our planet and it cal also calculate the adverse effects which the planet can face in future. Data will be key to understanding and, perhaps, forecasting space weather.

To survive its mission, the spacecraft will need to withstand temperatures outside the spacecraft of 2,500 degrees Fahrenheit (1,377 degrees Celsius). The probe also will have special heat tubes known as thermal radiators that will work to protect the inside of the craft.

Before the probe can answer some of the sun's mysteries, it will have to deal with its huge heat along with radiation, noted LiveScience.com The Johns Hopkins University Applied Physics Laboratory has been collaborating with NASA to make sure the probe survives its close-up with the sun. The Solar Probe Plus will also be protected from radiation, which can damage the probe's electrical circuits, especially its memory.
