Next Steps "Insights": Deploying Ready Instruments – Research – cnBeta.COM



According to foreign media reports, according to foreign media reports, NASA's "awareness number" has successfully traveled to Mars, but it will take some time to start a scientific verification mission. Insight arrived in Mars on the afternoon of November 26th in the United States in the east and flatly dropped Elysium Plain. After a few months, the unloading machine will carry out a detailed inspection of the interior of Mars.

The picture shows the concept map of art. Insight will use a robot arm to place a shield on a seismometer to isolate wind and temperature effects. Insights hit Mars on the afternoon of November 26, US time.

Before that, Insights will expand and eliminate two of the most important tools – a set of heat flow meters and ultra sensitive seismographs. The instrument should be placed on the surface of Mars with a glimpse of a robot arm. This has never been the case with previous Mars platforms, so the Insight team wanted to make this step even.

So, in the coming weeks, researchers will carefully analyze where they have gained insights and determine the optimal placement area. They then practice placement with a beta starter at the NASA Reaction Engine Laboratory. According to project fundraiser Elizabeth Barrett, researchers will conduct a "ground-up project" on a test bed to simulate the real environment in which the insight is in Mars.

Baret equated this placement mission to a "duck catch game".

"The placement of the instrument takes longer than a luxurious doll – you have to stop a couple of times, make sure it is held up, lift your arm and then make sure the instrument is firmly grounded. Open your arm."

In fact, the Insights robot must repeat this operation three times because it also places a seismic protective cover to prevent wind and temperature disturbance in data collection and analysis.

Barrett said that these deployment tasks should take between two and three months. It will take months later to gain insight into the active pursuit of scientific research. This time the heat flow meter sits 5 meters below ground and calibrates the heat flow meter and the seismometer.

When it is activated, the seismograph will begin to detect the "Mars earthquake" signal caused by Mars' internal vibration and the effects of meteorites. At the same time, the heat flow meter measures the heat flux at different depths. The Insight team wanted to know more about Mars's kernel by measuring a small pound rotation axis, which is obtained by pinpointing the state of insights.

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

Insight has sent back a small amount of information, including a photo of the dusty environment. This is the first Insight from Mars photo, which is a good guarantee for future data collection. Baret and team members said: "The area seems relatively flat, with plenty of sand, large cliffs or other obstacles that affect placement."

"We believe that this photo can help us determine the difficulty of placing an instrument," said Barrett. "I'm very glad to see that it's not hard to place an instrument here, I hope it is."

The English name "InSight" is the abbreviation "Internal exploratory work using seismic exploration, geodesy and heat engineering", which means "internal detection using earthquakes, geodesy and heat flow". Mars's surface mission plan will continue Mars (about two Earth years). Team members insist that Insight should cover so long enough to obtain sufficient data to meet the main mission objectives.
