U.S. NASA is preparing to launch a probe in August to study the Sun closer than any man-made object, revealing multiple mysteries behind the star.
The spacecraft called Parker Solar Probe is supposed to take off According to NASA, Xinhua news agency reports that the spacecraft carries a series of instruments to study the Sun remotely and directly .
According to NASA, the mystery of the solar wind acceleration, the constant flow of material by the Sun, and the other the secret of the extremely high temperatures of the corona. Parker Solar Probe instruments could also reveal the mechanisms at work accelerating solar energetic particles, which can reach speeds of more than half the speed of light when they are in motion. away from the Sun. Such particles can interfere with satellite electronics, particularly for satellites outside the Earth's magnetic field.
The biggest breakthrough for the spacecraft is its advanced thermal shield, according to NASA. "The thermal protection system (the heat shield) is one of the enabling technologies of the space mission," said Andy Driesman, director of the Parker Solar Probe project at the Johns Hopkins Applied Physics Lab. "It allows the spacecraft to operate at about room temperature."
The heat shield is a carbon-carbon composite sandwich surrounding nearly four and a half inches of carbon foam, or about 97% of air. "The launch energy to reach the Sun is 55 times greater than that needed to reach Mars, and twice that needed to reach Pluto," said Guo Yanping of the Johns Hopkins Applied Physics Laboratory, which designed the trajectory of the mission.

"During the summer, the Earth and the other planets of our solar system are in the most favorable alignment to bring us closer of the Sun, "said Guo. 19659010] (function (d, s, id) {
