The purpose of this lesson is to introduce students to the planet Mars. This lesson will begin by discussing the location and size of Mars relative to Earth, as well as introduce many interesting facts about this red planet. Next, the history of Martian exploration is reviewed and students discover why scientists are so interested in studying this mysterious planet. The lesson concludes with students learning about future plans to visit Mars.

Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!

Background for and techniques of visual observation, electronic imaging, and spectroscopy of the Moon, planets, satellites, stars, and brighter deep-space objects. Weekly outdoor observing sessions using 8-inch diameter telescopes when weather permits. Indoor sessions introduce needed skills. Introduction to contemporary observational astronomy including astronomical computing, image and data processing, and how astronomers work. Student must maintain a careful and complete written log which is graded. In this seminar we explore the background and techniques of visual observation and imaging of the Moon, planets, and brighter deep-space objects using 8-inch telescopes. (Some sample images appear in our "photo album".) Telescope work begins with visual observing, then we advance to CCD (charge-coupled device) cameras. Each class observing session meets one evening a week. Whenever weather conditions permit us to observe outdoors we do so! In cloudy weather we'll try some astronomical computing and image processing indoors instead. Either way, virtually all the work for the seminar is done during the evening sessions, so students must attend section every week in order to pass. Past experience has been that if you're really enthusiastic about hands-on out-under-the-sky astronomy, enough to be willing to deal with dressing warmly, tinkering with equipment, and committing one evening a week, 12.409 is great fun! One student wrote, "Unlike most seminars, you will earn your units and, unlike most other MIT courses, you will look forward to doing it!" But we'll be direct: 12.409 is not for everyone, and in past years many whose interest was merely casual found themselves unwilling to devote one entire evening every week to the class. If your interest is only casual then consider whether a more typical astronomy survey subject might be a better choice, since it'll have more outside preparation time that you can rearrange at your discretion and less in-class time that you can't.

Students use scaling from real-world data to obtain an idea of the immense size of Mars in relation to the Earth and the Moon, as well as the distances between them. Students calculate dimensions of the scaled versions of the planets, and then use balloons to represent their relative sizes and locations.

This course includes Quantitative introduction to physics of the solar system, stars, interstellar medium, the Galaxy, and Universe, as determined from a variety of astronomical observations and models. Topics: planets, planet formation; stars, the Sun, "normal" stars, star formation; stellar evolution, supernovae, compact objects (white dwarfs, neutron stars, and black holes), plusars, binary X-ray sources; star clusters, globular and open clusters; interstellar medium, gas, dust, magnetic fields, cosmic rays; distance ladder; galaxies, normal and active galaxies, jets; gravitational lensing; large scaling structure; Newtonian cosmology, dynamical expansion and thermal history of the Universe; cosmic microwave background radiation; big-bang nucleosynthesis. No prior knowledge of astronomy necessary. Not usable as a restricted elective by physics majors.

This set of activities is designed to help students develop an understanding of scale/distance and ordering the planets from the sun, understanding Earth's position in the solar system, and developing new ways of determining "order."

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

Students learn how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system. In accompanying activities, they explore how ground-based tracking and onboard measurements are performed. Also provided is an overview of orbits and spacecraft trajectories from Earth to other planets, and how spacecraft are tracked from the ground using the Deep Space Network (DSN). DSN measurements are the primary means for navigating unmanned vehicles in space. Onboard spacecraft instruments might include optical sensors and an inertial measurement unit (IMU).

Students will learn about the parts of the solar system. This will include the different planets and how they orbit around the sun.

Students create a model of the solar system using beads and a piece of string. The scale model is for distances planets are from the Sun, not sizes of the planets in comparison to the Sun. Students use ratios to calculate the distances they need to use to create their model. Once students complete their models, there are many possibilities for extension discussions and extension questions.

This is an introduction to the study of the solar system with emphasis on the latest spacecraft results. The subject covers basic principles rather than detailed mathematical and physical models. Topics include: an overview of the solar system, planetary orbits, rings, planetary formation, meteorites, asteroids, comets, planetary surfaces and cratering, planetary interiors, planetary atmospheres, and life in the solar system.

In this activity, students investigate the effect that thrust has on rocket flight. Students will make two paper rockets that they can launch themselves by blowing through a straw. These "strawkets" will differ in diameter, such that students will understand that a rocket with a smaller exit nozzle will provide a larger thrust. Students have the opportunity to compare the distances traveled by their two strawkets after predicting where they will land. Since each student will have a slightly different rocket and launching technique, they will observe which factors contribute to a strawket's thrust and performance.

YouTube video comparing the relative size of objects that students are familiar with (planets) and those that they are not (stars, galaxies, etc.) to allow for development of abstract concepts of massive sizes.

This is an activity to help students understand the abstract concept about how planets move around the sun and their relative size compared with other planets in the solar system.

Students will calculate their weight on planets in our solar system. Students will conduct an experiment to calculate how far they can perform a standing long jump on the moon and planets too!

This video gives students an animated view of the solar system, which keeps them actively engaged and focused. The students will learn the names of the planets and will be able to identify certain characteristics including size and spatial relation.
