![]() Rovers make in-depth observations at a variety of locations within their driving range. Landers make observations on their landing spot and do more in-depth science at one location. Satellites, fly-by or orbiting spacecraft, explore the features of a planet from a distance, making observations of large swaths of the planet. NASA sends three types of robotic explorers into our solar system: satellites, landers and rovers. ![]() Each mission gathers data that inspire more questions - questions scientists hope to answer using scientific instruments on board robotic explorers. Those at Mars will ultimately help NASA determine the best locations for future human exploration and Mars bases. These missions inform future exploration. ![]() NASA missions collect scientific data to help scientists and engineers better understand the features and environment of Earth and other planets and objects in our solar system. Their final design should be represented in a reasonably accurate two-view sketch on the student worksheet. Emphasize that design sketches are informal and do not have to be highly accurate.Encourage students to sketch their initial design ideas in their engineering journals.Provide students with a variety of materials they can use to build their models.This model will be used to demonstrate the potential detrimental effects of the shake test. Assemble a weakly-designed, partial model of a satellite in advance of teaching this lesson.(Optional) NASA’s Eyes on the Solar SystemĪn assortment of building materials, especially recycled or “found” materials, such as: Aluminum foil, cardboard, paper tubes or cardstock/manila folders to roll, construction paper, index cards, toothpicks, dowels or popsicle sticks, glue or tape, clay dough, buttons, pony beads, transparent copies of graph paper (to cut for solar panels), small cereal or other boxes, water bottles, string for hanging completed model (if desired) Management Images of satellites with components labeled – Download Cassini Diagram | Mars Odyssey Diagram Metric or standard ruler (one per team for shake testing) Oatmeal canister or mailing tube to simulate the rocket fairing size constraint The satellite must meet certain instrumentation criteria and robust constraints in order to successfully overcome vibration testing. In this potentially multi-day activity, students will use the engineering design process to design, build, test and improve a model satellite. This lesson provides students with an understanding of satellites, their use and structure, and power systems. For related resources in Spanish, see the Explora Más en Español section below.
