Summary

NASA is promoting the mission called the Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) and constructing new lander which will research Mars. The mission is constituted of three main objects.

First object is to analyze the seismic wave to know about Mars’s core.

Second object is to investigate heat-flow to know how hot inter planet is.

Third object is to observe how Mars rotate its axis, what material Mars is composed of, the material’s distribution and size and density of the planet’s core.

So InSight is expected to help us understand the detail of the Mars.

Review

I thought this article very surprising and interesting.

At first, in three points I was surprised. First, the ignorance of human-being for Mars. In this report, the writer told that human-being need to observe something about Mars. For example, Mars’s core and what kind of material Mars has. That because I have thought human-being have a lot of information about Mars, I was surprised that we don’t know such a basic information about Mars.

Second, the ability of the machine that will be used in InSight. It has main three function which will be able to move properly. I thought it surprising that the machine will move properly even after leaving the earth and changing environment completely.

Third, this is trifle. Two years in earth equal as a year in Mars. That is because I thought that time-flow speed is regular in the universe, this difference is very interesting to me.

And I also become to have interest in some portion in this article. The case that the research conducted by seismology will tell us the composition of the planet, the knowledge of heat-flow tell us the planet’s geology, the size of Mars’ wobble help us understand the size and density of the planet’s core.

These research are very interesting. So I want to check these kind of news by myself.
