According to “Future of Space Exploration Could See Humans on Mars, Alien Planets,” the 100-Year Starship project includes artists and science fiction writers, as well as scientists and engineers. What is the main reason for including people from the arts?

• Artists and science fiction writers are among the greatest critics of space travel, so changing their opinions is crucial to the success of the project.

• Artists and science fiction writers are great supporters of space travel, and they are willing to lend their time and effort to the project.

• The skills of artists and science fiction writers can help in the program’s aim of increasing public enthusiasm for space exploration.

• The program is so experimental that artists and science fiction writers understand it better than scientists and engineers do.

If humans someday colonize Mars, what must they do?

• write about it

• remember it

• improve it

• settle it

Which of these actions is an example of planetary motion?

• the sun’s movements

• the Earth’s movements

• rockets moving through space

• astronauts moving in spaceships

If future astronauts engage in interstellar travel, where will they go?

• from star to star

• between Earth and Mars

• between Earth and the moon

• anywhere within our solar system

In “Future of Space Exploration Could See Humans on Mars, Alien Planets,” how important does Mae Jemison think the support of the general population is to the success of space programs?

• The dedication and support of the general population is needed for a space program to succeed.

• A space program can succeed without public support, but getting funding is easier with it.

• The general population’s support has less of an impact than the government’s support.

• Technology is the key to a space program’s success, not the support of the public.

"Without the development of a method to warp or shrink space-time, or a new propulsion system—both ideas that the 100-Year Starship program is exploring— humanity would need to find a way to overcome some of its instability problems."

According to this paragraph, what is most likely to happen to space exploration if political instability continues?

• New technologies for space travel will not be developed.

• There will be no lasting economic benefits from space travel.

• Lengthy journeys through space will be threatened by a lack of cooperation.

• Nations that colonize other planets will merely move their political problems there.
