Program Wildest Weather in the Solar System

  • 1. Build background about space probes.
    Show students the National Geographic video "Space Probes." Then explain to students that a space probe is an unpiloted, unmanned device sent to explore space. A probe may operate far out in space, or it may orbit or land on a planet or a moon. It may make a one-way journey, or it may bring samples and data back to Earth. Most probes transmit data from space by radio. Ask: Why do you think there are so many different types of space probes? Elicit from students that they collect different science information about very different environments. The probes must be able to withstand the different extreme environments to collect data.

    2. View and discuss a variety of space probe images.
    Display the photo gallery Space Probes. Invite volunteers to read aloud each caption as you scroll through. Then, as a class, discuss and list on the board how structures of probes are different. Ask: What types of equipment do different probes include? How do you think equipment would be protected from different weather and environmental conditions?

    3. Explore space probe measurement on the Cassini probe.
    Explain to students that a space probe records observations of temperature, radiation, and objects in space. Different probes have different mission objectives. There are lunar (moon) probes, solar (sun) probes that measure solar radiation, and probes that investigate the terrain on rocky planets or the gases on gaseous planets. Introduce the Cassini space probe. Display the web page NASA: Cassini Solstice Mission—Inside the Spacecraft and explore the diagram together. Ask:

    • What types of instruments does this probe have?
    • Why do you think information collected by this probe may be important to scientists?
    • Which instruments would you include on a probe of your own design to observe weather on other planets?

    Informal Assessment

    Based on information from this activity, have students write a paragraph with ideas about instruments they would want to include on a probe of their own design. Have them include at least one idea from a space probe they have observed today, but encourage them to include new ideas too.

    Extending the Learning

    Use National Geographic Explorer Magazine's poster Saturn's Wildest Weather to give students more information about the Cassini space probe and weather conditions on Saturn.
