Firstly, SPP hopes to find out why there is such a vast discrepancy between the surface and atmospheric temperatures of the sun. At the closest approach, the spacecraft will come as close as 3.7 million miles to sun's surface - about eight times closer than any spacecraft has come before.
"We can't get to the very surface of the Sun", but the mission will get close enough to answer three important questions, Christian said.
Strides in technological advancement have allowed humans to send spacecraft to the moon, distant asteroids, and planet Mars, but is it possible to send a probe to the scorching hot sun? "We can't get to the very surface of the sun", he added while affirming the importance and significance of this mission.
Specialists indicated that this unstable corona, the big hole in the heart of the Sun, is thought to be cooler compared to the rest of the star's atmosphere. The probe will get an assist from Venus, using seven flybys to gradually get closer to the sun until it reaches the ideal point. A second question has to do with solar winds.
He told LiveScience.com that researchers have had problems finding out more about the sun because "we're 93 million miles away".
'Get Out' tops box office with huge $30.5 million in ticket sales
Building up its box office total: The Lego Batman Movie earned an extra $19 million in its second week, nabbing second place. It finished at the top of the box office all three days while Lego Batman limped in with about half that at $9.6 million.
Researchers also want to know how the solar wind get its speed as well as why the sun occasionally produces high-energy particles known as solar energetic particles. He wonders if this suggests that something, perhaps solar winds are coming off the sun faster than the comet was moving.
The U.S. Space agency NASA has announced a solar probe that will gather interesting information for scientists to help them predict any major solar events and its impact on our planet.
Third, NASA hopes the probe will identify the causes of the Sun's intermittent emissions of high-energy solar energetic particles, which are potentially unsafe to unprotected satellites, spacecraft, and astronauts.
The National Aeronautics and Space Administration (NASA) is mulling over sending its first robotic spacecraft to the Sun, next year. The challenges of such a mission While the mission is an unmanned project, there is still the need for protection of the spacecraft itself and the sensitive instruments it will carry. If the thermal radiators work as intended, the instruments should remain at "room temperature, Christian says".
Unlike landing probes on Mars and Moon, scientists can not land a probe on the Sun, but they will try to make the closest approach to the Sun while keeping the spacecraft alive. The probe will also be protected from radiation that could ruin the electrical circuits inside the probe.
