NASA Will Launch A Car-sized Spacecraft To Study Sun In August – Xinhua

WASHINGTON, July 22 (Xinhua) – The US NASA Space Agency is preparing to launch a probe in the morning of August to study the Sun closer than any object manufactured by the US. Man, revealing multiple mysteries behind the star. 19659002] According to NASA, the spacecraft called Parker Solar Probe is expected to take off as early as August 6 from a United Delta IV Heavy Launch Alliance.

The atmosphere of the Sun constantly sends magnetized materials to the outside, enveloping our solar system

The magnetic energy coils can burst with the light and radiation of the particles that pbad through Space and create temporary disturbances in the atmosphere, sometimes blurring the radio and communication signals near the Earth

. To understand its origins, one must understand the Sun itself and that's where Parker Solar Probe intervenes, according to NASA researchers.

The spacecraft carries a range of instruments studying the Sun both remotely and directly.

A scientific task is the mystery of the solar wind acceleration, the constant flow of solar material, and the other is the secret of the extremely high temperatures of the corona, according to NASA.

In addition, Parker Solar Probe instruments could reveal the mechanisms behind the acceleration of solar energetic particles, which can reach more than half the speed of light when they are in motion. they are away from the sun. Such particles can interfere with satellite electronics, especially 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) is one of the mission's enabling technologies. spacecraft, "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 solar panel cooling system allows the solar panels to produce energy under the intense heat load of the Sun and the fault management system protects the spacecraft during long periods of solar system operation. "The launch energy to reach the Sun is 55 times greater than that required to get to Mars, and twice that needed to get to Pluto," said Guo Yanping of the Johns. Hopkins Applied Physics Laboratory, which designed the trajectory of the mission

The Delta IV Heavy is one of the most powerful rockets in the world

"During the summer, the Earth and other planets of our solar system are the most favored. "Alignment to allow us to get closer to the Sun," said Guo.
