NASA’s mission, Parker Solar Probe, prepared for touching the sun mission has left for its historic journey on Sunday. This mission, prepared at a cost of $ 1.5 billion, could be delayed by 24 hours. It was sent on August 12 at 3.31 pm according to Eastern Day Time. Earlier on Saturday, August 11, it was not launched for technical reasons.
This spacecraft will rotate the sun 24 times at 4.30 million miles per hour. During this journey to reach the sun, this spacecraft will pass through the gravitational route of many planets. In this, the gravitational route of Mercury will also help it. It will be the first to reach so close to the sun. Earlier the missions were not successful.
When Parker is Close To The Sun?
The 1.5 billion dollar Parker Solar probe, which is the closest study of Sun, head of the Solar System, has to cover its journey several times. The reason is that it is the heaviest spacecraft ever released by NASA. More than 600 tons is fueled in it. The weight of a large laboratory and thick heat-resistant armor of a small car is different. Someone may think that the sun would have been pulling the spacecraft with its huge gravity, then with the help of a lot of fuel, what was the need to get the most powerful rockets like ‘Delta 4 Heavy’ in this work? Then remove the misunderstanding.
The energy that it takes to leave the sun’s vomit i.e. the direction of Mars, is to add 55 times its energy to the sun’s direction. And for this, there is only a 65-minute window around four o’clock in the morning, so that it faces at least the charged particles of the Van Allan belt, hovering around the earth. Keep in mind, this spacecraft is going on a long journey for seven years (or more). During this, it will take 24 rounds of sun and use the planet Venus for six to seven times.
Its first proximity to the sun will be made on November 5, 2018, and in December it will start providing its study data to the Earth. But its water will be on its Impact in December 2024. When it is only 6 million kilometers away from the surface of the sun, and at the speed of 700,000 kilometers per hour. It is at the threshold of Corona’s threshold in the sun’s temperature of 3 million degrees Celsius. Must be passing.
This probe has to find two very big secrets. How does the temperature increase in the temperature of 5500 degrees, increase the temperature of the sun to 500 times? And two, what is the reason for the continuous solar winds being thrown out of the sun? Hopefully, in the next seven years, we will know much about the center of our existence, our nearest star.
Why Sun-Probe Sunscreen Is 8 Feet?
American Space Agency NASA has created an 8-foot flying saucer to protect Parker Solar probe from the sun’s high temperature. Mission Project Scientist Nikki Fox in APL told that his team has named this protective shell as flying saucer. It has been made after a decade of hard work. It is a 4.5-inch thick carbon foam layer. The layer of white ceramic paint has been clamped on the part of the spacecraft that will be on the sun, so that it can return the sun’s heat back. The weight of this security layer of 8 feet width is approximately 73 kg. It will be stuck firmly between the sun’s terrible temperature and the Parker Probe.
Why They Give Name Parker?
The name of this spacecraft has been named after the physician Eugene Newman Parker. He presented many concepts of transmitting energy through the stars. This name of NASA has been named after the name of a living scientist for the first time. Parker, 91, saw this vehicle last year, on which the last part of his name is marked.
When They Launch And Where?
The Parker Solar probe did not leave on Saturday. The launch of this satellites was fixed at 3.33 PM in accordance with Eastern Daytime on Saturday. It was later increased to 3.53 by 4.28 hrs. Later, for technical reasons it was decided to increase its launch till Sunday. Parker Solar probe team had feared the weather to be a hindrance in the launch of the spacecraft . Therefore, its launch window has been kept 13 days from 11 August to 23 August. Weather Officer Kathy Rice told at a news conference that it would be 65 minutes for the launch.
