Next steps for Insights: deploying ready-to-run tools – scientific research – cnBeta.COM

Beijing time, November 29, news, according to foreign media reports, the "insightful number of NASA" successfully landed on Mars, but it will take some time to begin the task of scientific expertise. Vzglyad arrived on Mars in the afternoon of November 26 in the eastern United States and landed without difficulty on the plain of Elysium. A few months later, the landing gear will conduct a detailed inspection of the interior of Mars.

The illustration shows a map of the concepts of art. Insight will use a robotic arm to mount the screen on a seismometer to isolate the effects of wind and temperature. Insights landed on the surface of Mars in the afternoon of November 26, in the USA.

Prior to this, Insights will deploy and debug two main tools, a drilling heat flow meter and a set of ultra-sensitive seismographs. The tool must be placed on the surface of Mars by a robotic understanding lever. This has never been the case with the previous landing sites of Mars, so the Insight team wanted to make sure that this step was smooth.

Therefore, in the next few weeks, researchers will carefully analyze where the data are and determine the optimal area of ​​deployment. They then practice the deployment process using a beta-landing device at NASA's Jet Propulsion Laboratory. According to Elizabeth Barrett, the instrumental project manager, the researchers will conduct a "land management project" on a test bench to simulate the real environment in which insight is on Mars.

Barrett compared this deployment mission with a “challenging version of a doll catching game.”

“It takes more time to deploy a tool than to grab a doll — you need to stop several times, make sure you hold it, raise your hand, and then make sure that the tool is firmly on the ground. Open your hand.

In fact, the Insights robotic arm must repeat this action three times, because it also places a protective cover on the seismometer to prevent wind and temperature from affecting data collection and analysis.

Barrett said that these deployment tasks take two to three months. Then it will take several more months to figure out how to actively conduct research activities. This time, the heat meter is drilled 5 meters below the ground and calibrates the heat meter and seismometer.

When it is activated, the seismograph will begin to detect the signal of the "earthquake of Mars" caused by the internal vibration of Mars and the effects of meteorites. At the same time, the heat flow meter will measure the heat flux at different depths. The Insight team also wanted to learn more about the Martian core by measuring the small influence of the axis of rotation of Mars, which is obtained by accurately tracking the position of understanding.

These observations will help us better understand the internal structure and composition of Mars, and this information will help us understand the formation and evolution of rocky planets.

Insight sent back a small amount of information, including a photograph of the environment, covered with dust. This is the first Insight from Mars photo, which is a good guarantee for future data collection. Barrett and team members said: “The area seems relatively flat, with a lot of sand, no large stones or other obstacles that affect deployment.”

“We believe that this photo can help us determine the complexity of the deployment of the tool,” said Barrett, “I am very glad to see that it’s not difficult to deploy the tool, I hope so.”

The English name “InSight” is the abbreviation “Study of the interior using seismic surveys, geodesy and heat transfer”, which means “internal detection using earthquakes, geodesy and heat fluxes”. The mission plan for a landing device on the surface of Mars continues during the Martian year (approximately two Earth years). Team members say Insight should take so long to gather enough data to achieve key mission objectives.
