How far is the traveler No. 1, the farthest spacecraft on the planet?

Far -far human dream -the farthest spacecraft far from the earth

The navigator No. 1 is the farthest spacecraft from the earth. On February 14, 1990, the camera of the traveler No. 1 was facing the sun and took a series of photos of the sun and planets. This is the first solar system "portrait" we saw from the outside. At that time, the number 1 of the Oceanians was about 4 billion miles (6 billion kilometers).

What is the farthest spacecraft from the earth?

Traveler No. 1 Aerospace in November 2021 was nearly 140 million miles (23 billion kilometers) from Earth. The navigator No. 1 and its twin spacecraft "Ocean 2" was launched 16 days apart in 1977. Both spacecraft flew over Jupiter and Saturn. Both navigator spacecraft are traveled between the interstellar space. Traveler No. 1 officially became the first Earth spacecraft to leave the solar system and crossed the sunlight top in 2012. Earlier this year, it sent back a message, which was a weak and monotonous buzz of interstellar space.

The beginning of the navigator

The two navigators were designed in the early 1970s. Their construction is to use the rare planetary group on the sun in our solar system. This combination that occurs only every 176, which allows navigators to reject from a planet to the next planet through gravitational assistance.

The navigator began to obtain Jupiter images in January 1979. Travelers completed their encounter with Jupiter on the 1st in early April of that year. The sailing person took over in late April and continued until August. The two spacecrafts took more than 33,000 Koben stars and five major satellites.

Then the navigator went further. When they launch, no spacecraft has reached Saturn, and the distance between Saturn and Earth is 10 times that the distance between the earth and the sun. Therefore, the four-year journey of Saturn was a major leap. The navigator reached Saturn in nine months from November 1980 to August 1981. Travelers then left the solar system on the 1st. The sailing person continued to reach Uranus in January 1986 and arrived at Neptune in August 1989.

The farthest spacecraft is still moving forward

In 2017, astronomers used the Hubble Space Telescope to observe the path of the navigator. About 40,000 years later, after the two spacecraft are no longer running for a long time, Traveler 1 will pass through the Gliese 445 star 1.6 light years in the deer leopard constellation. At the same time, the navigator No. 2 was nearly 12 billion miles (19 billion kilometers) from the earth. The sailor No. 2 will pass through the place where Rose 248 stars and 1.7 light years from the Fairy Constellation in about 40,000 years.

Voyager 1 (Voyager 1) is an unmanned solar system spatial detector developed by NASA (NASA), weighing 825.5kg and launched on September 5, 1977. Some functions have been operating normally as of now, and it has continued Communication with NASA's Shenzhen -space network. [3] It is the farthest artificial aircraft in history, and the first artificial aircraft to leave the solar system. Benefiting from several gravity accelerations, the flight speed of Traveler 1 is faster than any existing aircraft, which makes the number of sister ship travelers who launch two weeks earlier two weeks will never surpass it. Its main task was ended on November 20, 1980 after the Jupiter System and the Saturn system in 1980. It is also the first detector to provide Jupiter, Saturn, and its satellite detailed photos. On August 25, 2012, "Traveler No. 1" became the first spacecraft to cross the solar circle and enter the interstellar media. As of August 220, 2020, Traveler No. 1 is in the position of 150.02 AU (2.24 × 1010 km) from the Sun [4], which is the farthest artificial object from the earth.

Traveler No. 1 is currently flying along the bilateral track and has reached the speed of the third universe. This means that its orbit can no longer guide the spacecraft to fly back to the solar system. It has become an interstellar spacecraft like the pioneer 10 and the pioneer 11 that has stopped operation.

The original goal of Traveler 1 was to detect Jupiter and Saturn and its satellites and rings. Now the task has become the top of the solar wind, and the particle measurement of the solar wind has been measured. The two traveler's detectors are used as a source of power with three radioactive homogencin thermal motors. These generators have now greatly exceeded the first design life. It is generally believed that they can still provide sufficient power to make spacecraft continue to contact the earth in about 2020. The scientific instruments on the nuclear battery can ensure that the scientific instrument on the traveler's number continues to work until 2025. In 2036, the power transmission of signal transmission will be exhausted. [5] Once the battery is exhausted, "Traveler No. 1" will continue to advance to the Milky Way Center, but it will no longer send back data to the earth. The spacecraft, also known as space vehicle, spacecraft, or spacecraft, is a variety of aircraft that basically move in accordance with the laws of celestial physical mechanics in the cosmic space outside the earth atmosphere. The difference between spacecraft and natural celestial bodies is that it can be controlled to change its running orbit or recycle. Common spacecraft include artificial satellites, space detectors, aerospace planes and various space stations.
