US Space Agency Returns to Mars with InSight Lander

The American space agency’s lander InSight is to arrive on Mars at the end of November, 2018. Unlike NASA’s Curiosity rover,InSight will not move across the planet’s surface. Instead it will become the first spacecraft (航天器)used only for exploring underground. It will study the geography of Mars, searching for signs of Martian (火星的)quakes.

InSight is a project of U.S. and Europe. It is 6 meters long and 1.5 meters wide. It weighs 360 kilograms. InSight’s 1.8-meter robotic arm will put two experiments in place. Both are designed to explore underground of Mars to learn about the inside.

Bruce Banerdt is the lead scientist for InSight. He viewed the spacecraft as a robot that can take care of itself. “It’s got its own brain. It’s got an arm. It can listen and feel things. It pulls its own power out of the sun,” he noted.

Thomas Zurbuchen, one of the heads in NASA, said the results of the InSight project could “change the way we think about the inside of our earth.” But, first,InSight will have to land on Mars undamaged. Since Mars exploration started in the 1960s, only about 40 percent of the explorations have succeeded.

Tom Hoffman is InSight’s project manager. He said earlier successes do not lessen the concerns for each new exploration. “That we’ve done it before doesn’t mean we,re not nervous and excited about doing it again,” he said.

InSight will enter the Martian atmosphere (大气层)traveling at 19,800 kilometers an hour. It will slow for landing on a wide flat area on Mars. If all goes well, InSight could carry out its experiments in about 10 weeks. The InSight project is expected to continue for one Martian year, about two years on Earth.

32. What is the difference between InSight and NASA’s Curiosity rover ?

A. The size. B. The design. C. The speed. D. The task.

A. InSight travels at an unchanged speed.

B. InSight is the project of America and Japan.

C. InSight has the functions (功能)of a robot.

D. InSight is mainly powered by the natural gas.
34. What will be one of the contributions (贡献)of the InSight project according to Zurbuchen?

A. It will help us understand the geography of Mars.

B. It will change the way we think about the inside of the earth.

C. It will help carry out more experiments on Mars.

D. It will get more information about the reasons for Mars’ quakes.

3 5. What is Hoffinan’s attitude towards this exploration of the InSight?

A. Confident. B. Satisfied. C. Concerned. D. Frightened.
