Which pulling force makes the Parker spacecraft the fastest?

The latest spacecraft successfully launched by NASA on August 12, 2018 will reach 430,000 miles, equivalent to 692,000 km / hour as it approaches the Sun.

A rifle bullet fired at a speed of about 2,736 km / h, but the Parker ship was 250 times faster when it came to the Sun 7 years later and would be the fastest speed object ever. now created by humans.

NASA said the unmanned ship will reach speeds of 692,000 km / hour, which is about 201 km / sec on December 24, 2024 when it approaches the Sun and is flying in the 22nd round of 24 rounds. around this fire star.

At such a burning rate, a car-sized probe will break the current record of the unmanned spacecraft Helios 2 launched into space in 1976, or by comparison of NASA. it was fast enough to fly from Philadelphia to Washington DC in just a second.

The Parker ship is very close to the Sun and is accelerated by the Sun's enormous gravitational pull.

Extremely fast moving objects made by humans

The Parker ship is responsible for studying the Sun's atmosphere, energy eruptions and charged particles that the Sun produces. The data collected will help improve the forecast of "space weather" - phenomena that can destroy satellites, adversely affect the astronauts' health and disrupt radio signals. and power transmission networks on Earth.

But what makes this ship fly so fast?

Mr. Yanping Guo, Parker Project Manager and Project Manager, said: "This scout ship will have such a fast speed because it will be very close to the Sun and accelerated by the huge suction force of the Face. Heaven ".

The Earth orbits the Sun at an average distance of about 150 million kilometers. When approaching the Sun, the narrow trajectory of the Parker vessel will hold the ship at a distance of 6.4 million km. At this distance, the Earth's stronger Sun attraction 475 times. The larger the gravitational pull of the celestial body, the stronger the ship will be pulled.

But it is not easy to get the ship into the appropriate trajectory. According to Mr. Guo, it is necessary to "destroy" the Earth's own orbital speed - that is, the speed at which our planet and everything on Earth revolves around the Sun - so that the ship can "fall." down to the Sun ".

In doing so, scientists have outlined an orbit that will take the ship closer to Venus in each of its revolutions, thanks to Venus's gravitational pull to change the path of the ship and release some force. Smoking of the Earth against the ship. Thus the ship will be pushed towards the Sun and more affected by the attraction of the Sun.

"Gravity support" has been applied to many space missions, including NASA's Horizons flight to Pluto. In 2015 this flight sent extremely precious photos about this dwarf planet.

But no flight has been supported as much as the Parker. This ship will have 7 times to fly through Venus throughout its journey. The first time will take place on October 3, 2018 and the last time will be on November 6, 2024, ie only a few weeks before it reaches its maximum speed.

What if the Parker ship flies past you at 692,000 km / hour? Because there is no air in the universe to transmit sound waves, you will not hear anything. Physicist Greg Matloff at New York University of Technology, and an expert on rocket propulsion, says that an object moving at a very high speed in space will not make noise because in the universe almost vacuum.

You can't even see a fast moving object, astronomer Jonathan McDowell of Harvard-Smithsonian Center for Astrophysics said. But you probably do not want the ship to come near you like that, because you imagine if a heavy truck ½ ton crashed at you at a speed of 161km / hour, this ship is at maximum speed still skimming. Crossing you with a force and even more powerful than 20 million times.
