Next Steps for "Previews": Deploying Tools Ready to Launch – Scientific Survey – cnBeta.COM

Beijing Time November 29, according to foreign media reports, NASA's "Insight Number" has successfully landed on Mars, but it will take some time before it begins a scientific test. Insight arrived on Mars on the 26th of November in the eastern United States and landed seamlessly on Elysium Plain. Within a few months, Lander will take a detailed look at the interior of Mars.

The picture is an art map. Insight uses a robotic arm to position the shield on the seismometer to isolate wind and temperature effects. Insights landed on Mars in the afternoon on November 26 in the US.

Prior to this, Insights will deploy and debug two major tools, a flow meter and a set of ultra-sensitive seismographs. The device must be located on Mars' surface with a robotic viewing arm. This has never happened with the previous Mars landing gear, so the Insight team wanted to make sure this step was smooth.

So, in the next few weeks, researchers will carefully analyze where insights appear and determine the optimal deployment area. They then practice the deployment process using the beta lander at the NASA Jet Propulsion Laboratory. According to Elizabeth Barrett, Project Project Leader, researchers will carry out a "ground building" on the test bed to simulate the real environment in which Mars is seen.

Barrett likened this naval mission to the "difficult version of the doll-playing game".

"Storing the instrument takes longer than capturing a doll – you have to stop several times, make sure you hold it, raise your shoulder, and then make sure the device is firmly on the ground.

In fact, the Insight robotic arm needs to repeat this operation three times because it also places a protective cover on the seismometer to prevent winds and temperatures from interfering with data collection and analysis.

Barrett said these deployment tasks last for two to three months. It will then take a few more months to explore active research activities. This time, the flowmeter has to drill 5 meters underground and calibrate the flowmeter and seismometer.

When activated, the seismograph begins to detect the "Mars earthquake" signal due to the internal vibrations of Mars and the impact of meteorites. The heat flow meter also measures the heat flow at different depths. The Insight team also wanted to learn more about Mars' core by measuring the Martian rotation axis, which is achieved by accurately tracking the visibility position.

These observations will help us better understand the inner structure and composition of Mars, and this information will help us understand the creation and development of rock planets.

Insight sent back a small amount of information, including a photo of the dust-covered environment. This is the first insight from Mars, which is a good guarantee for future data collection. Barrett and team members said: "The area seems relatively flat, with lots of sand, large rocks, or other obstacles that affect deployment."

"We are convinced that this photo will help us find out the difficulty of using the tool," Barrett said. "I am very glad that there is no hard work on the tool, I hope it will be."

The English name "InSight" is an acronym for "Inside Surveys Using Seismic Examination, Geodesy and Thermal Transport," meaning "internal earthquake detection, geodesy and heat flow". The mission plan for Mars Landing Mars continues for the Martian year (approximately two years Earth). Team members say Insight must take so long to gather enough data to reach the mission's key goals.
