Beijing Time on November 26, after six months of flying in space, the Insight detector quickly approached Mars and planned to land on Mars on Monday in the United States.from

After taking off from Earth and passing a 301 million mile (548 million kilometer) long journey, the Insight Detector will land on Mars at around 3 pm EST (4 am Beijing time on Tuesday).

The mission control team from NASA's Jet Propulsion Laboratory plans to make final corrections to the orbit of Flight Inspectors on Sunday, bringing it closer to the entry point 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 Mars landing, atmospheric friction, parachutes and brake rockets will slow down the speed of insight. After 6.5 minutes of landing, the Inspector's speed will slow down to 5 miles (8 km).

After landing on the surface of Mars, the Inspector will remain silent for 16 minutes, waiting for the dust to be ignited around the landing site to "regulate" and then open the solar cell.

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

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

The Intersection landing point is around 373 miles (600 km) from Curiosity Rover Landing Point 2012.

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

Express the rocky planet formation

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

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

Although the structure of the Earth and other forces has removed much of its early history, Mars is believed to have preserved its original state, creating a geological time machine for scientists.

The main scientific instrument carried by Insight is a very sensitive seismograph made in France that detects even the slightest vibration caused by "Mars earthquakes" and the impact of meteors.

Scientists hope that during the two-year mission period, they will observe 10 to 100 Martian earthquakes, 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 above the detector, this design proved to have little effect.

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

The radio transmission device is responsible for sending signals to Earth to track rotation sway unknown to Mars, to understand the size of the "core" of Mars and whether it remains liquid.

NASA officials say that the next Mars Insight and mission, as well as other tasks that are still in the planning stage, will be the precursor to Martian human exploration.
