Israel's spacecraft maneuver to leave Earth's orbit and capture the moon & # 39; – Israel News



The Israeli spacecraft genesis faces the first of the great challenges of its moon mission: "catch the moon" or move out of Earth's orbit to enter the moon.

If the maneuver succeeds, the spacecraft, which once seized the moon's gravitational training, will begin to pave the earth's natural satellite and gradually draw closer to it, with the aim of accomplishing a planned moon landing in exactly one week's time.

If the events of the upcoming go as planned, Genesis will make space history and become the first privately built spacecraft to complete the challenging mission. The very low cost of the project, compared to other $ 1

00 million moon missions, is also an important milestone in the new era of human interplanetary journey that could be expected to grow and commercialize as a result of this mission's success.

Eran Schmidt, Deputy Director of the Project and SpaceIL's Land Commander, said that the spacecraft has so far brought the earth into a wider elliptical path through maneuvers designed to speed up and move it further and further away from the ground.

About 15:15 in Israel, the spacecraft is scheduled to be 400,000 kilometers away from the planet and close to the moon, then engines will be operated to slow it down From 8,500 km per hour to 7,500, the maneuver will be carried out autonomously through a series of instructions to the spacecraft's computer, and the slowdown will allow it to be trapped in the moon's gravitational pull and then orbit the satellite elliptically, drawing as close as 500 kilometers from the moon's surface.

If the maneuver fails, there will be another option within an hour or more later, Schmidt says, adding that if the second attempt fails, the spacecraft will slip out of both the Earth's and Moon's gravitational traits and open up in another circle around the sun. This would spell the mission's failure. If successful, the spacecraft would move to a distance of 200 kilometers from the moon in the next phase, paving it for 14 hours each turn. Then a further planned maneuver would bring the spacecraft at a height of 15 kilometers above the moon, where it would receive a series of instructions leading to an autonomous landing using its engines. When the vehicle comes within four to five meters of the moon surface, the engine will shut down so that the aircraft can fall to the ground. Experts hope the spacecraft's special landing gear will allow it to survive the fall.

The engineer described the three major maneuvers in the mission as the launch, capturing the moon and the autonomous landing. Unfortunately, the success of confronting a challenge does not mean that the others also succeed. Schmidt says there are two other optional landing sites. The plan is for the landing to take place at sunrise, as the daytime hours on the moon are very high. The spacecraft will then work for 72 hours before it gets too hot.

Genesis, built by SpaceIL using Google's XPRIZE and LunarX, began as competitors in 2007, which gave various entrepreneurs the challenge of building a spacecraft that could land on the moon, travel about 500 meters and send a video of what could catch. The competition ended without winners, but all competitors continue their efforts to build spacecraft that can reach the moon. For the next two years, the entrepreneurs of the other projects, along with Genesis, also hope to land land vehicles on the moon.

Last year, the US space company said that nine US companies or companies that were partners with Americans could compete for LunarX bids to fly NASA cargo to the moon. Last month, NASA revealed the dozen bids it wants to bring to the moon with a budget of $ 2.6 billion over 10 years.

Some of the private interest in the moon survey is related to the development of technology to exploit the mineral's mineral riches. It is too early to say whether the dream of utilizing the moon's resources can work for the foreseeable future, but many people regard the satellite as the new "wild boar" and seek ways to overdo it. Gold, silver, titanium and helium 3 isotopes needed for nuclear fusion exist on the moon and in nearby asteroids. But the moon's greatest economic value seems not only to be limited to its rare minerals, but also to material that is also abundant on the ground: water.

The price of fuel is one of the most expensive aspects of space travel. Huge amounts are required to pull off the Earth's orbit. Some 85% of the weight of Saturn5 used to launch the American astronauts to the moon was made of fuel. The same goes for rocket fuel for this day. By comparison, fuel is only 4% of the average car's weight. Therefore, if you want to plan long journeys in space, the spacecraft must have enough fuel for the entire mission or find its way to fuel on the way. The moon could accommodate such a tank center. Frozen water in its poles can be broken down and used as rocket fuel. Therefore, the one who succeeds in claiming the water on the lunar poles will gain a significant advantage over the course of conquering the solar system.

Apart from the story and entrepreneurial achievements, success in capturing the moon will also launch Genesis & # 39; scientific missions: Decoding the magnetic mysteries of moon clouds. In research conducted in collaboration with the Weizmann Institute, a magnetometer will be used on the spacecraft to try to understand how moonrocks got their magnetism. Prof. Oded Aharonson from Weizmann's Earth Research Department, who heads the project, said the moon has no magnetic fields. But research has found that some moon clouds have magnetic qualities, and research aims to find out how they have acquired that capacity: whether it happened as a result of an internal process that occurred at an earlier stage of the moon's life or due to an external factor such as an asteroid landing.

The Earth's magnetic field was created as a result of the circulation monitoring of its metal and fluid nuclei. But as far as scientists know the moonists, it is much smaller and colder than the earth, and the nucleus is frozen. Therefore, the moon is not assumed to have its own magnetic field. The research aims to learn about the history of the moon through the magnetism of its rocks, also to discover whether the moon may have had a magnetic field in the past. While the spacecraft orbits the moon in smaller and smaller circles, before thelanding, the magnetometer measures the rocks' magnetism in various regions to learn whether there is a system of age and character of the magnetic stones that could tell us something about their physical properties.
