The worlds chosen for this year's contest are some of the most mysterious and distant in our solar system: Uranus' moon Miranda, Neptune's moon Triton and Pluto's moon Charon. Each has been visited by spacecraft during a single, brief flyby. NASA's Voyager 2 spacecraft flew by Miranda and Triton in the 1980s, and the New Horizons spacecraft flew by Charon in 2015. All three flybys provided the only up-close – and stunning – images we have of these worlds.

To enter the contest, which is hosted in the U.S. and more than a dozen countries, students must submit an essay of up to 500 words explaining why they would want to send a spacecraft to explore the world of their choosing. Essays can also be submitted by teams of up to four students.

Winning essays will be chosen for each topic and grade group (5 to 6, 7 to 8 and 9 to 12) and featured on the NASA Solar System Exploration website. Additionally, U.S. contest winners and their classes will have the chance to participate in a video conference or teleconference with NASA.

Entries for the U.S. contest are due Feb. 20, 2020, on the NASA Scientist for a Day website. (Deadlines for the international contests may vary by host country.) Visit the website for more information, including rules, international contest details and past winners.

For teachers interested in using the contest as a classroom assignment, learn more here. Plus, explore these standards-aligned lessons and activities to get students engaged in space travel and planetary science:

• 
  Art and the Cosmic Connection

  Students use art to describe and recognize the geology on planetary surfaces.

  Grades K-12

  Time 1-2 hrs

• 
  Solar System Bead Activity

  Students create a scale model of the solar system using beads and string.

  Grades 1-6

  Time 30 mins - 1 hr

  *NEW* Planetary Travel Time

  Students will compute the approximate travel time to planets in the solar system using different modes of transportation.

  Grades 4-6

  Time 30 mins - 1 hr

• 
  Sizing Up Pluto

  Using measurements taken by the New Horizons spacecraft as it flew by Pluto in July 2015, students practice their math skills in a real-world application and see how new data can change scientific understanding.

  Grades 4-12

  Time 30 mins - 1 hr

• 
  Solar System Scroll

  Students predict the scale of our solar system and the distance between planets, then check their answers using fractions.

  Grades 5-8

  Time < 30 mins

• 
  *NEW* Create a Solar System Scale Model With Spreadsheets

  In this activity, students use spreadsheet software and their knowledge of scale, proportion and ratios to develop a solar system model that fits on a playground.

  Grades 5-12

  Time 30 mins - 1 hr

• 
  Using Light to Study Planets

  Students build a spectrometer using basic materials as a model for how NASA uses spectroscopy to determine the nature of elements found on Earth and other planets.

  Grades 6-11
