The glory of Mars, and the glory of man

The results brought by Mariner No. 4, this spacecraft, are mostly negative, not positive. Mars does not have... and does not have... and does not have... results, if it is true that it ascends by the same amount as Mars, or descends, for it has descended by this much.

As much as it fell as far as Mars, it rose as far as man. This experiment that man conducted, with which he sent his mute, inanimate messenger, tearing space apart, until the time of his being struck in this distant space, and keeping a promise, this experiment raised the value of man to the same extent as it lowered the value of the red planet.

- The glory of Mars has faded.
And the glory of man shone.

The story of this shining human glory is a wonderful story
It is a long story, and we will break it down into a few, in the following few pages, as a record of this great event.

- The orbit of Earth, Mars, and spacecraft:

We begin by describing the three orbits that took place
It includes Earth, Mars, and spacecraft together.

This is an illustration of the sun, and around it are two orbits: the orbit of the Earth as it revolves around the sun, and the orbit of Mars as it also revolves around the sun. Then a third orbit is the path of the air vehicle, Mariner 4 (translated in Arabic as “Navigator”). It was launched from Earth on the twenty-eighth of November 1964, and reached and passed Mars in mid-July 1965. The spacecraft was then launched into the vastness of space to orbit around the sun. A planet made of human planets
As we previously mentioned.

The spacecraft met Mars on July 14, 1965, when it was 134 million miles away.
the earth .

This does not mean that the vehicle traveled only 134 million miles in space to reach Mars.

This is because, during the many months that the journey took, Mars was not stationary, but rather was moving. The vehicle is also on track, aiming on its journey to the place where Mars will be after these long months. It has traveled more than 134 million miles, and many more.
In fact, the vehicle traveled 350 million miles during its journey.

- The spaceship with its four wings folded:

This is the spacecraft. It was loaded in a hurry, and the specialists prepared to place its white shield on it, before placing it in a place above the missile to launch it. It is noted that the vehicle had its wings folded to save space and to be covered by the cover, i.e. the protective shield. The vehicle sheds this covering when it reaches space, extends its four wings and supplies it with sunlight, converting it into electricity, which is the source of the power the vehicle needs, as we will mention later.

Because these wings did not open in space on the Russian Zond spacecraft, which the Russians launched two days after Mariner, Zond continued on its journey to Mars silently, not hearing from the Russian Earth scientists, nor hearing it either. For this same reason, Mariner No. 3 failed. The Americans had launched it three weeks before its brother, No. 4, to be precise, on November 5, 1964.

The rocket that lifted the spacecraft:

This is the Atlas Agena missile, and in its white head, on top of which the Mariner spacecraft rested. The moving structure that helped build the missile (to the left) was removed from the missile, as well as the “secret” tower (to the right) that connects the missile to the power sources. That is until the missile is launched. Between them is a cord like the umbilical cord between a mother and her newborn.

They called it the Atlas-Agena missile, because it actually consisted of these two missiles. The first one below is Atlas and the second one above it is Agena. The missile was launched, and Atlas began to burn, raising the entire object, which weighed 125 tons, to a height of 90 miles before it ran out of fuel. At this moment, this missile separated from the spacecraft, and its white shield, which had protected it from the pressures of ascent, separated from it as well. Scientists had not forgotten what happened to Mariner 3, the one whose flight was spoiled, that its shield had not fallen. They were certain that the shield had fallen when the strength of the radio signals that the craft was sending increased, because the shield, which was made of metal, was weakening it.

The second Agena missile immediately ignited and increased the vehicle's speed, in about two and a half minutes, to about 18,000 miles per hour. Then the missile went out, and it has not separated yet, because it has another job. Then the spacecraft was orbiting the Earth as satellites orbit. It was over the Atlantic Ocean and headed towards Africa and then to the Indian Ocean. When 32 minutes and one second had passed since its rotation, the Agena rocket was ordered to ignite again, bringing the vehicle to the speed at which it could overcome the Earth’s gravity and completely sever its ties with the Earth. The vehicle reached this speed, which is 25,000 miles, and even increased slightly, in about two minutes. The speed actually reached 25,598 miles per hour.

When the Ajina rocket completed its duty, it separated, and the small spacecraft remained alone moving in space, falling under the gravity of the sun, just as the sun attracts the Earth, Mars, and all the other planets. The vehicle became a planet, but it was a manufactured planet, launched, and all its calculations and all its movements were calculated, so that it would meet the planet Mars at a certain point, after a certain time, which is seven and a half months.
