Science and Technology Daily, Washington, November 26 (Reporter Liu Haiying) At 3:01 pm ET on the 26th (Beijing time at 4:01 am on the 27th), after only a few minutes but a little long wait, National Airlines Scientists at the Space Agency's (NASA) Jet Propulsion Laboratory (JPL) have finally received radio signals from the "Insight" Mars probe. NASA then announced that the "Insight" successfully landed on the Mars Elysium Planitia and is about to begin a two-year mission to Mars.
The "Insight" is the first US-based Mars probe after the 2012 "Curious" probe. It is responsible for performing NASA's first deep-seismic exploration mission in Mars, on the composition and status of the Martian core, the thickness of the crust, and the structure. Conduct surveys to help scientists reveal the evolution of rocky planets in the solar system.
Before landing on Mars, the Insights probe had been flying in space for 205 days and had six orbital corrections. At 2:47 pm on the 26th of the US East, the detector entered the Martian atmosphere on time and on schedule, and in less than 7 minutes, the flight speed was reduced from 19,800 km to 8 km, and the effects of high temperature and dust were overcome. Landing smoothly. Although NASA has long-term and successful experience in landing on Mars, the "Insight" is still facing many new challenges. Therefore, the successful completion of each step in the landing process has aroused the applause of JPL-controlled indoor scientists. At the moment of receiving the signal to confirm the successful landing, from the Times Square in New York to the California Science Center in Los Angeles, the NASA scientists cheered and the NASA scientists were excited.
The "Insight" landing point is located in the western section of the Martian Ehrlich Plain, with flat terrain and rare rocks. NASA said that the choice is mainly for safety: First, the terrain is low, and it can ensure that there is a thick enough atmosphere above it to facilitate the detector to slow down. Second, it is closer to the equator and can ensure sufficient sunlight as a detector. Solar panels are powered. In addition, the evidence provided by the NASA Mars Odyssey orbiter also indicates that the soil at the landing site is easy to drill, making it easier for scientific instruments to penetrate inside Mars.
After the "Insight" successfully landed on Mars, the NASA team of scientists will begin to deploy the scientific instruments carried by the detector. They expect that after a month, the "Insight" will be able to "double-star flash" with the "Curious" 600 km away, helping humans understand the mystery of this red planet as soon as possible.
