Expository Writing Prompts on Space and Planets

Very little inspires more curiosity than space. From telescopes that let us see the planets to the rockets that take us to the stars, space and space travel are the things that were borne of the imagination, and these expository writing prompts on space and planets are sure to get your student’s imaginations running wild.



Prompt 1: You are an astronaut on a peaceful, exploratory mission to Planet Q. As a representative from Earth, you are to present three gifts from our planet. What items will you take? Write a proposal to the sponsors of your mission explaining why you think these will make excellent tokens.

Prompt 2: Using your knowledge of science, geography and environment, explain what we would have to do to survive on another specific planet in our Solar System.

Prompt 3: We always dream about the possibility of life on other planets. Can you imagine, however, what we must look like to aliens who may be watching us? Write a story from the point of view of an alien who is observing the people of Earth.

Prompt 4: Virgin Galactic is planning on launching flights into space for regular civilians in the next few years. The cost of the trip will be $250,000 and the trip will include three days of training in addition to a flight into outer space for two and a half hours. If you could afford it, would you like to go? Why or why not?

Prompt 5: Weigh the risks and rewards of space flight by explaining why you would or would not like to be a passenger on the Space Shuttle.

Prompt 6: Describe an experiment to be conducted on board the Space Shuttle.

Prompt 7: What do you think lies beyond the edge of space? Do you think we can ever know whether or not the Universe is infinite?

Prompt 8: You are an asteroid. Introduce yourself to someone, explaining your typical day, your life processes, and how you deal with any dangers you routinely face.

Prompt 9: Make up a new planet. Describe the important features of the landscape, what the climate is like, and what lives there. Write from the viewpoint of the first visitor to this planet.

Prompt 10: You are going on a trip to the moon. Think about three things you would take with you and tell why you would take these three things.

Prompt 11: You have the chance to be the first student astronaut to explore another planet. Would you accept the job? Give reasons why or why not.

Prompt 12: Do you think mankind will ever colonize another planet in your lifetime? Why do you think we will or we won’t?

Prompt 13:  There is an argument that it is a waste to spend money on a space program when there is so much need right here on Earth. Do you think it would be wiser to take the billions spent on NASA and instead try to fix the world’s problems, or do you think that exploration in space is just as important and may eventually solve some of Earth’s problems when we are able to colonize another planet?

Prompt 14: Do you believe there is life on other planets?
