Preface
Exploring the mysteries of the universe is a very romantic and long-lasting thing.
Since mankind first wanted to understand the universe and tried to explore the universe, today, the space technology of many countries has developed by leaps and bounds.
During the exploration, the probe plays a vital role, but what is curious is that there is a cliff-like gap between the countries that are deeply accomplished in spaceflight.
It is understood that the farthest detection distance of the American detector is 24.2 billion kilometers, and that of India is 215 million kilometers.
Compared with these two alone, there is such a big gap, so how much is China's farthest detection distance?
Voyager 1
The United States can be said to be a leader in space exploration, and in the last century, it was already ahead of many countries in the exploration of the moon.
In terms of probes, the United States also has many advantages, and the "Voyager 1" probe is a very outstanding work developed by the United States.
This probe, which was launched into space in 1977, carried the mission of unveiling the mystery of the universe, and began a romantic interstellar journey.
During its work, images of many planets were transmitted back to Earth, including Jupiter, Saturn, Neptune, Uranus, etc., and even Earth, which was also shown to the public.
It is precisely these precious images that allow scientists to obtain a large amount of data on the distant earth, and also allow human beings to see with their own eyes what those planets look like.
In this regard, scientists have conducted in-depth research on the space magnetic field, meteorology, solar system and other issues, so as to lay more foundations for the next aerospace industry.
The most unexpected thing is that Voyager 1 is really very hard, originally scientists designed him to have a lifespan of only five years, but he has been working until now.
For nearly 47 years, Voyager 1 has been at work, acting as the eyes of humanity as it steps into the uncharted realm of deep space.

However, over time, Voyager 1 also had to deal with chip damage and aging instruments.
In November 2023, it suddenly malfunctioned, and the data transmitted to Earth was only a messy code.
Even the manual for compiling the probe was decades old, and now it is too far away from the Earth, which leads to a long-term information gap between the Earth and it.
It took up to 22.5 hours for Voyager 1 to receive the instructions sent to it by Earth, and it would take 45 hours for Earth to receive a reply.
But even so, everyone is unwilling to give up such a "veteran" and rescue him as much as they can.
Beijing Daily client 2024-04-23 - "Voyager 1" sent back readable data again after 5 months
Finally, in April of this year, Voyager 1 once again successfully sent valid data to Earth.
This probe, which has flown 24 billion kilometers from Earth, continues its journey into space.
USS Mangarion
In fact, many people do not have a very good impression of India, thinking that India not only has a dirty environment, but also cannot guarantee social security.
In addition, even the infrastructure is not perfect, and such a country seems to have been in a backward state.
However, India has a very high pursuit of science and technology, and when it comes to the aerospace industry alone, India attaches great importance to it, and when the aerospace industry of China and the United States and other countries is gradually developing, India is also not far behind.
And perhaps one of the most proud exploration technologies for India is the "Mangarion" probe they launched to Mars.
It took only 15 months for the Mangarion to be developed, and then in November 2013, it was successfully launched.
And on September 24, 2014, Mangarion successfully entered the orbit of Mars, much to the surprise of many.
At that time, the purpose of designing the probe was to explore Mars, but many people were not optimistic about India's space technology, but the fact is that India really did it.
China National Space Administration2014-09-24 - India's first Mars rover has successfully entered Mars orbit
This rover, equipped with four devices and a camera, has carried out a full range of exploration of Mars, which marks a great success for India in this field.
The most commendable thing is that the research and development cost of the Mangarion probe is only about 74 million US dollars, and this value is only one-tenth of the research and development cost of the United States.
In terms of cost alone, this probe does have an advantage over the United States, which was 215 million kilometers away from Earth during its mission.
However, after 8 years of orbiting Mars, in October 2022, it ran out of power due to a total solar eclipse for a long time, and finally declared its life end.
Although the Mangarion is far inferior to the American Voyager 1 in terms of lifespan, at the time of design, the estimated life of this probe was actually only 6 months, so it was far beyond expectations.
Observer.com2022-10-05 - After eight years of continuous operation, India's Mangalian Mars rover has confirmed that it has lost contact
Tianwen No. 1
Speaking of China's progress in space technology, it has now reached the point of world fame, so much so that Western countries led by the United States are extremely shocked.
In the field of Mars exploration, China also has a very good probe, that is, "Tianwen-1".
In July 2020, Tianwen-1, independently developed by the mainland, was successfully launched and entered the predetermined orbit to carry out the mainland's first Mars exploration mission.
Unlike India's Mangalian, which orbits Mars, the continent's Tianwen-1 also has a mission to land on Mars.
In order to ensure that Tianwen-1 can land on Mars more safely and smoothly, researchers have designed deceleration effects in terms of parachute, power, and shape.
The Tianwen-1 weighs about 5 tons in total and is equipped with seven scientific instruments for different purposes, including cameras that take images, and has excellent performance.
China Aerospace News 2022-03-24——"Tianwen-1" sent back images丨Recently, the American "Perseverance" Mars rover was photographed
In December 2021, Tianwen-1 was 350 million kilometers from Earth, and in March 2022, it was 277 million kilometers from Earth.
In the process of exploring Mars, Tianwen-1 has been working diligently, providing countless data files for mainland scientists.
In the space exploration project, the mainland has been working hard to make progress, in addition to Tianwen-1, we also have other very outstanding space equipment, in the process of space exploration, we will create more miracles.
