on board.Ĭhandra’s arrays were unfolded like an accordion. Chandra’s two 3-panel solar arrays produce about two kilowatts of power (roughly the same power as a hair dryer!) for the heaters, science instruments, computers, transmitters, etc. ![]() The power is then stored in three banks of batteries, and distributed in a carefully regulated manner to its parts. Chandra generates the electrical power needed to function from its solar arrays. NASA’s Chandra X-ray Observatory, for example, travels about a third of the way to the moon at its farthest point from Earth, in order to observe the X-ray Universe. Solar arrays have a lot of surface area in which to be pointed towards the Sun to gather all the energy needed. Many spacecraft have solar panels to convert sunlight into the electrical power to help run the spacecraft. If time permits, you can have an extra 2 sheets of paper that are lighter or heavier than the original sheets.Ī solar array is a group of solar panels that captures energy from our Sun to generate electricity as a system.2 sheets of rectangular (or square) paper of the same size for each student.While keeping a free-form and experimental frame of mind, students will be encouraged to try a variety of techniques, which might include folding or crumpling the paper followed by observations of the effectiveness of each method. Using ordinary paper, such as copy paper, students will experiment with ways to compress paper into the smallest area and/or volume. Folding is a technique that purposefully minimizes the space that an item takes, but allows for efficiently unfolding the item into its useable state without damage to the item. Introduce the idea that folding is a solution for this problem. ![]() Think of telescopes, solar arrays, surface rovers (e.g., Mars Curiosity Rover), etc. There are often objects that are very large in their open state. Introduce the idea that taking anything into space requires that it take up a minimum amount of space. Precision may improve the look of these models, but they will all function well without a high degree of precision. No project will be ruined by inaccurate folding. ![]() These projects are designed to be successful with children and novice folders. Using spacecraft design as the main inspiration, we will create mini-solar arrays, a simple folding space telescope, and a mini-sunshade. In this project, we will explore how origami can help us understand how objects can fold up to take up a very small space and unfold to be very large. NASA’s Chandra X-ray Observatory, as well as other telescopes, have looked at many of these explosions and the debris fields they leave behind (called “supernova remnants”). This energetic event, known as a supernova, hurls the outer layers of the star into space, creating an elegant tapestry of energy and stellar debris. When a star about 10 to 15 times more massive than our Sun runs out of nuclear fuel, it will collapse onto itself and then create a giant explosion. In astrophysics, there are instances where the expansion and unpacking of origami demonstrates similarities to what scientists witness, for example the death of stars.
