The psychic spacecraft will use different propulsion to travel deep into space

BingMag.com The psychic spacecraft will use different propulsion to travel deep into space NASP NASA, which has experience flying to various asteroids, will launch the spacecraft to the valuable asteroid Psyche next year. This time, however, there is a major difference. When a psychic spacecraft uses its propulsion to move in space, it will rely more on its brain instead of arm force.

Maybe like science fiction - It may seem imaginary, but the quiet and high-efficiency electrical energy provides the force that can propel the spacecraft to the main belt of asteroids between Mars and Jupiter, and bring it to its target, the asteroid psychic.

It will be launched in August 2022 (August 1401) and will travel about 2.4 billion kilometers in three and a half years to reach the asteroid psychic. Scientists believe that this metal-rich asteroid, which is more valuable than the global economy, may be part of the core of a sub-planet, as the main building block of early rocky planets.

So as soon as the spacecraft orbits the asteroid The mission team will use scientific tools to study it to obtain information about the formation of rocky planets such as Earth.

This The spacecraft will be launched on the SpaceX Falcon Heacy rocket with massive chemical engines to launch and escape the Earth's gravity, but will rely on its own solar electric propulsion for the rest of the journey and after detaching from the launcher.

For fuel, the psychic spacecraft is full of xenon tanks. Which is the same neutral gas used in car headlights as well as in plasma TVs. The spacecraft's four propulsors use electromagnetic fields to accelerate and expel charged atoms or xenon ions. The thrust of the ions creates a driving force that gently displaces the psychic in space and emits blue rays of ionized xenon. It is the hand of man. But this is enough to accelerate a psychic deep in space. Because there is no post-atmospheric force to prevent the spacecraft from moving and it will be possible to reach a speed of 320,000 kilometers per hour using ion propulsion.

Due to the high efficiency of the Hall propulsion system, the propulsion systems of the psychic spacecraft can run uninterrupted for years without running out of fuel. For this purpose, Psychic will carry 922 kg of xenon in its tanks. The engineers estimate that the mission will require about five times that amount of fuel if traditional chemical propellants are used.

Lindy Elkins-Tanton "Even when we first designed the mission in 2012, we talked about the solar electric propulsion program," said the University of Arizona. Without it, the psychic mission is not possible, and this propulsion forms part of the mission character. "The propulsion that a specialized team needs to use to calculate the spacecraft's orbits and orbits." Space will go and the powerful Falcon Hui rocket will put it in a direction that 7 months later, in May 2023 (May 1402 solar), Mars' gravity will be used to help it move. In early 2026, the propulsion engines will steer the spacecraft into orbit around the asteroid, and will continue to do so until the exact orbit of the planet is determined.

This is because scientists still have comprehensive information. They have nothing to do with psychics because the asteroid is only seen as a small dot in the telescope. Ground-based radar shows that the asteroid is about 226 km wide and has the shape of a potato, but scientists do not know exactly how its gravitational field will work until they reach it.

As the mission conducts its scientific research for 21 months, navigation engineers use electric propulsion to move the spacecraft in orbits to gradually bring the spacecraft closer and closer to the psyche.

NASA's Jet Propulsion Laboratory (JPL) in Southern California, which manages the mission, used a similar propulsion system in the 1998 Deep Space 1 mission. The spacecraft passed an asteroid and a comet and completed its mission in 2001.

After that, it was a "Dawn" or "Dawn" mission powered by a solar electric propulsion system for travel and orbit. He used the asteroid "Vesta" and then the dwarf planet "Ceres". Mission Down was the first spacecraft to orbit two extraterrestrial targets. The mission lasted 11 years and ended in 2018, when the last hydrazine fuel was used up. Maxar Technologies has been using solar electric propulsion to power its commercial communications satellites for decades. But for their psychic spacecraft, they needed to adapt Hall's high-performance propulsion system to move deep into space, and that's where JPL engineers came in. Both teams hope that the first use of Hall propulsion beyond lunar orbit will help overcome the current limitations of the propulsion system. "" Technology "Solar propulsion provides the right combination of efficiency, power and cost savings and can play an important role in supporting future scientific missions to Mars and beyond."
