NASA launches automotive size spacecraft to study Sun

Washington, July 23 (IANS) The US NASA space agency is preparing to launch a probe in August to study the Sun closer than any man-made object , revealing several mysteries behind the star.

According to the Xinhua News Agency, the Parker Solar Probe Probe is expected to take off as early as August 6 on an alliance of Delta IV Heavy Launchers Heavy

The Atmosphere of the Sun Constantly Sends Magnetized Material outward, enveloping our solar system far and wide. beyond the orbit of Pluto.

Magnetic energy coils can burst with light and radiation from particles that travel in space and create temporary disturbances in our atmosphere, sometimes blurring radio and communication signals near the Earth.

Therefore, the key to understanding its origins lies in the understanding of the Sun itself and it is there that Parker Solar Probe comes into play, according to NASA researchers.

The spacecraft has a range of instruments to study the Sun. directly.

A scientific task is the mystery of the solar wind acceleration, the constant flow of the Sun 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 energy particles, which can reach speeds of more than half the speed of light when they are in motion. they move 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. "This 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 required to get to Mars, and twice that had to happen to Pluto," said Guo Yanping of the Applied Physics Lab Johns Hopkins, who 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 the other planets of our solar system are in the most favorable alignment to allow us to get closer to the Sun, "said Guo.
