On November 26th, in Beijing, after a six-month flight in space, the Insight detector is quickly approaching Mars and plans to land on Mars in the US on Monday.After taking off from the earth and passing the 301 million miles (548 million kilometers) long-distance road, Insights Detector will land on Mars at around 15:00 pm (Beijing time on Tuesday).

The task control team of the NASA Jet Propulsion Laboratory is planning to bring the Inspector's final correction to the flight trajectory on Sunday and bring the point of entry into the Mars atmosphere closer.

If everything goes well, Insight will enter the Mars atmosphere at 12,000 miles (19310 km) in about 24 hours. During landing on Mars, atmospheric friction, parachutes and brake rockets slow down the speed of insight. After a 6.5 minute descent, the inspector's speed will slow down to 5 km (8 km).

After landing on the surface of Mars, the Inspector will remain silent for 16 minutes, with the powder fired around the landing site "tuning" and then opening the solar cell.

Engineers in the Jet Propulsion Laboratory hope to use small satellites launched at the same time to verify that Insight is safe.

The Jet Propulsion Laboratory also hopes to take a picture of the situation around the landing site.

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

The 800-pound (360 kg) insight is the 21 US Mars search mission (including the mission to fly over Mars in the 1960s).

Revealing the formation of rocky planets

Insight is the first detector to specifically detect the mysteries beneath the surface of Mars, and will use seismic tracking and underground drilling in the next 24 months (about 1 Mars year) to explore Mars and the Earth over 4 billion years. Origin and formation of rocky planets.

Isi Analysis will help us understand the formation of the planet, “said Bruce Banerdt, Insight's lead investigator and jet propulsion laboratory scientist, at a press conference last week.

Although the structure and other forces of the world erase many of its early history, it is believed that Mars has largely preserved its original state and has created a geological time machine for scientists.

Insight's main scientific instrument is a highly sensitive seismograph that senses the slightest vibration caused by the "Mars earthquake" and the meteor effect in France.

Scientists hope that during their two-year tenure they will observe 10 to 100 Mars earthquakes, and that 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 was mounted on the detector, which proved to have little effect.

Insight also carries a German-made drill that can drill to a depth of 5 meters from the ground.

The radio transmission device is responsible for monitoring the rotational movement Mars is not aware of, for signaling the Martian "core" size and for transmitting signals to the Earth to continue being melted.

NASA officials, Insights & # 39; s and the next Mars mission, as well as other tasks in the planning stage will be the beginning of human exploration of Mars, he said.
