The sun, a perfect sphere of hot plasma in the center of our solar system, is responsible for life on Earth. However, our star is poorly understood due to the unimaginable extremes of radiation and heat that it radiates. NASA will now illuminate this star after directing its Parker Solar Probe at 213,200 miles per hour against the sun.
NASA's Parker Solar Probe, an unmanned spacecraft the size of a small family car, is already the closest man to the Sun – now only 24 million kilometers from its fiery surface.
The NASA probe will begin its second of 24 sun encounters tonight at 11:40 am (6:40 pm CEST)
And its latest mission will expose the Parker probe to the extremes of cosmic radiation ̵
According to NASA estimates, it will travel at 343,000 km / h (343,000 km / h) – fast enough to fly 100 times in an hour around the world.
The first solar encounter took place last year, and the probe is expected to approach the sun steadily until its last passage in 2024, when it is only 3.8 million miles from the st ars surface.

The NASA spacecraft was built to protect its precise instruments from the fierce radiation and enough from the sun divert heat.
NASA must maintain an internal temperature of 29 ° C (84F) and perform vital measurements of the corona – the aura of the plasma surrounding the Sun – to better understand our next star.
Wealth of Data Scientists It is expected that six of them are expected to find out why the Corona 300 is hotter than the Sun's surface – a long-standing mystery among space explorers.
And another unanswered question is how the sun can produce such tremendous material springs called solar flares or coronal mass ejections.

These ions charge particles at normal velocities up to half the speed of light before all objects in the solar system are flooded and they are soaked in deadly radiation.
The Earth is protected by this thick atmosphere and a strong magnetic field of our planet and for the most part they only manifest as auroras at the North and South Poles.
However, stronger cosmic events can affect Earth electronics, with GPS and related services known to go offline.
Naur Raouafi, a Parker Solar Probe project scientist, said, "Parker Solar Probe provides us with the measurements necessary to understand the solar phenomena that have been baffling us for decades.

" To close the connection, a local scan of the solar corona and young solar wind is required, and Parker Solar Probe does just that. "
A mission to the depths of the sun's needed mate materials that are able to withstand conditions that humanity has never experienced before.
To meet the amazing astrophysical challenges NASA had to produce new materials with remarkable thermal properties.
An 11.5 cm thick carbon composite shell was designed to attach to the probe to provide the bulk of its protection.
