Long distance traveled by 548 million kilometers The vision is close to Mars and ready for landing tomorrow – Science Exploration –

In Beijing on November 26, after six months of space flight, the Insight detector is fast approaching Mars and plans to land on Mars on Monday in the United

After taking off from Earth and going through a long-distance journey of 548 million kilometers, the Insights Detector will land on Mars around 3 pm (Beijing time Tuesday).

The mission control team at the NASA Jet Propulsion Laboratory plans to make a final correction to the Inspector's flight orbit on Sunday, approaching it from the point of entry into the Martian atmosphere.

If all goes well, Insight will enter the Martian atmosphere at a speed of 12,000 miles (19310 km) in almost 24 hours. At the time of landing on Mars, atmospheric friction, parachutes, and brake rockets will slow down the insight. After 6.5 minutes of landing, the inspector's speed will decrease to 5 miles (8 km).

After landing on the surface of Mars, the inspector will remain quiet for 16 minutes, waiting for the dust to ignite around the landing site to "set" and then unfold the solar cell.

Engineers at the Jet Propulsion Laboratory expect to use small satellites launched simultaneously to confirm that the Insight has landed safely.

The Jet Propulsion Laboratory also hopes to receive a snapshot of the situation around the landing site.

The Insight landing point is approximately 373 miles (600 km) from the 2012 Curiosity Rover Landing Point.

The insight of 800 pounds (360 kg) is the 21st US Mars exploration mission (including the Mars mission in the 1960s).

Reveal the formation of rocky planets

Insight is the first detector to specifically detect the mysteries below the surface of Mars and will use seismic monitoring and underground drilling in the next 24 months (about 1 year of Mars) to explore Mars and Earth in more than 4 billion years. The origin and formation of rocky planets.

Bruce Banerdt, chief investigator at Insight and a jet propulsion laboratory scientist, told a news conference last week that "insights will help us understand the formation of the planet."

Although the structure of the Earth and other forces have erased most of its initial history, Mars is believed to have largely preserved its original state, creating a geological time machine for scientists.

The main scientific instrument carried out by Insight is a highly sensitive seismograph made in France, which detects the slightest vibration caused by the "Mars earthquake" and the impact of meteors.

Scientists hope that during the two-year mission period they will observe 10 to 100 earthquakes from Mars, and the resulting data will help them understand the size, density, and composition of Mars.

The Viking Mars probe, launched in the 1970s, also carried a seismograph, but mounted on top of the detector, this project proved to have little effect.

Insight also carries a German-made drill that can drill up to 16 feet (5 meters) deep into the ground.

The radio transmitting device is responsible for sending signals to Earth to track the rotational oscillation that Mars is not aware of, to understand the size of the Martian "core" and whether it is still molten.

NASA officials said that the Insights and the upcoming Mars mission, as well as other tasks still in the planning stages, will be a prelude to the human exploration of Mars.
