If you are interested in NASA and its Space missions and keep a lot of information about the space, you may have heard the space probe name many times. NASA uses this space probe for almost every space mission. Without space probes, NASA is no longer possible to miss any space missions. But what is this space probe actually? Why is it launching in space? How does this space probe work? How do they communicate with NASA in the world? I will discuss these issues related to the space probe today.

The pictures given here are only some space-related stock images of spacecraft. They typically do not reprint or mimic any space program or any spacecraft or any space probe.

What is space probe

Simply put, space probe is a non-human spacecraft that is sent to space to research on specific issues. When we need to know something from space or our solar system, such as the need to capture the close image of the moon or any planet-satellite or any other comet, we need to collect information from the information collection and research, then we To send a space probe near. As we send, you or I do not send, send NASA or send another suitable institution. Space probes carry special high quality cameras and other instruments with them so that they can take photos and research if needed.

Some space probes fly from targeted planet or satellite to zyacara photos and collect other information. However, most space probes enter the target of its target and rotate it around and gives us the necessary information to research about them. For example, its close-up picture, temperature, etc., which are generally not available in the world. There is no man in these space probes. These space probes work only to collect data and return these data to people in the world.

Space probe history

The first probe sent to space was called Sputnik-1 which was launched on October 4, 1957. The Soviet Union launched the Sputnik-1. Then on January 31, 1958, United States launched another space probe, called Space Explorer, which was named Xplorer-1. Space probes launched earlier this year were not sent to research on any planet or satellite outside the Earth. Rather, these space probes were launched to monitor the Earth from outside the Earth. They were also launched for some kind of testing, to see if they were kept in spaces or whether there was any problem and they could work properly. After launching this space probe, the competition started unexpectedly going on between the United States and the Soviet Union.

Then, when the space began to move to the probe space, the US and the Soviet Union sent the country's frequent space probes out of the world. The space probe named Mariner-2 revolves around Earth's satellites and other planets in the space of the first space. This Mariner-2 first studied with other planets. On December 14, 1962, it came near Venus and gave us different information about this planet. This probe ensures that the planet's temperature is much higher. However, this space probe did not capture any image of the planet.

Then the Space probe named Mariner-4 was the first probe that took pictures of a planet and sent it to the people. On July 14, 1965, the probe went near Mars and sent pictures of this planet to humans. Looking at the pictures taken by this probe, it can be ensured that the atmosphere of the planet Mars is cold and like a lot of moon. Then the mariner-9 space probe entered the planet Mars orbiting the first planet. It was the first space probe to enter the planet's orbit and research the planet.

Space probe development

The probes that have been sent in space in the first place have only circulated our neighboring planets within our solar system and have studied them. But with the development of technology, these space probes have become increasingly advanced and more functional and are still underway. Most space probes collect information about only the Earth and other surrounding planets. However, some space probes are launched with telescope and other such devices, so that they can be researched from our galaxy far too far and very far away from the constellation. Occasionally on TV we see many news about new planets or satellites in a galaxy far away. They are basically credit for such space probes. We know the names of such advanced technologies and space probes. For example, SpaceCraft, Orbiter, Lander, Rover etc.

However, the most famous and the most high-powered space probe is the name of the Voyager-1. This is the only man-made spacecraft that has been able to travel so far in space, as did not find any other space. This space probe was launched in 1977 and already it has crossed Jupiter and Saturn. It is currently moving towards the end of our solar system. According to the February 1, 2010, this space probe is about 16.8 billion kilometers away from our planet. For more details on this space probe, please read our article below-

How do space probes communicate?

First of all, we can not understand all the details of the space probes using what technology uses and communicate with the world and in what way the information is sent. Because, NASA does not publish all the details of all their technologies. But the main concept, which everyone knows, is that radioover technology is used for communication. But not at all. Some of the spaces that are doing research on the outer space in Orbital, some of those information are physically returned to the Earth. For example, about 382 kg of Lunar Samples were brought back to the world in Apollo missions for research. These types of information that are physically returned are one of the most valuable information among space programs.

However, Nissan has thought of using lasers instead of radio waves for such communication. Using these high frequency lasers will make communication faster and easier with space probes. Communication is time consuming with those space probes currently located millions of kilometers away from Earth. For example, to communicate with Mars about the rover that was sent to communicate via radio, it can take several minutes or hours to send commands and receive response from SpaceCraft.

As mentioned earlier, NASA does not communicate exactly with the spaces probe using any technology and publishes very detailed information about it, but it can be assumed from the general radio communication system that this is how it is possible. Of course, space probes are both radio transmitters and radio antennas, see detailed information about radio transmitters and antennas. Space probes must use certain radio frequencies, and as long as they have to send signals from millions or billion kilometers away, there must be many high energy radio waves. Digital data is encoded in radio waves, which is the radio receiver located in the world, to find those specific frequency channels.

Similarly, the antenna, which is equipped with a space probe, will scan the signal in a specific frequency, the space probe is easily detectable and space probes are working. The same technology is used when using radio in space, like two points in our world, but since the distance is very large, so many high frequencies have to be used. But the signals on the radio communication system are somewhat lost or lost somewhere, then the signal is transmitted again. Although it takes a few milliseconds to re-transmit the radio at any point of the globe, but it can take up to several minutes to several hours in a million kilometer of space.

However, instead of using the high frequency laser for communication instead of radio-wave, it can be reduced to a great extent. If this is really possible, then it will be a breakthrough imprint in space science.

So this was a small explanation about the space probe and its history. Here's the end of today Hope you enjoy the article today. If there are any questions or opinions, please tell in the comments section.
