To traverse the surface of the Moon or Mars, a vehicle must be able to think for itself. At NASA's Jet Propulsion Laboratory's testing ground, a team of scientists demonstrates the rover that will soon wander over the Martian landscape.

Marvie loves watching the planes land at airports, and she made a diorama of one for her friends Justine, the ladybug. She used a cardboard box, paint, and backyard treasures to create her diorama. Part of the "Marvie" series.
See how geckos inspired new NASA technology that makes things stick to each other in space. Potential future applications might be to grab and service satellites or to salvage space garbage. Part of the “Crazy Engineering” series.
How do you plot a course to Mars, from one moving planet to another? What are the impacts of space travel on the body and can human beings survive the trip? Looks at the plans for a flight to the Red Planet.
The engineers at NASA are studying cellphones and computers as a means to create a mini-satellite called a CubeSat. CubeSats are small but highly capable of performing a variety of space missions. Part of the “Crazy Engineering” series.
Fly into this high-tech career and learn about satellites, airplanes, and maybe even flying cars of the future. Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. Part of the "I Can Be Anything I Want to Be A to Z" series.
NASA engineers are looking for new ways to explore Mars. They are working with a small helicopter that could help scout trails for future explorations into space. Part of the “Crazy Engineering” series.
NASA’s "Juno" spacecraft traveled 1.7 billion miles to reach its destination: the planet Jupiter. Before "Juno’s" journey, NASA engineers had to develop a spacecraft capable of surviving the trip. They researched and created "Juno," a solar-powered spacecraft. Part of the “Crazy Engineering” series.
In 1990, when the first images from NASA's Hubble Space Telescope were too blurry to use, JPL scientists and engineers went to work to devise a fix. They created a camera with corrective vision to bring Hubble images into sharp focus. Part of the “Crazy Engineering” series.
Ion propulsion might sound like science fiction, but engineers at NASA are using it to drive NASA’s "Dawn" spacecraft through the solar system. Learn how ion propulsion works and why it is the reason "Dawn" will be the first spacecraft ever to orbit two solar system bodies beyond Earth. Part of the “Crazy Engineering” series.
Second in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This second component contains segments that provide science background (Four Forces of Flight, Newton's Laws, and others) to help students understand aviation concepts. Additional segments show the teacher how to conduct activities (building models or demonstrations) and acquire materials to be used in these activities.
Humans have always been intrigued by the idea of flight. Experiments with Hot Air Balloons led to a pig and duck being the first air travel passengers. From there, the Wright Brothers created the first airplane, and aviation was off to the races. From the jet engine and military aircraft to passenger planes, worldwide travel is now a matter of hours rather than days or weeks.
First in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This first component contains six ten-minute segments that explore (1) humankind's historical preoccupation with the idea of flight and the life and times of the Wright Brothers; (2) the science concepts of control, lift, and propulsion; and (3) evolution of the science of flight since the Wright Brothers.
The engineers at NASA are studying two new technologies to help image distant Earth-like planets. Coronagraphs are tiny instruments fitted inside telescopes to block light and help scientists study clues as to whether life is present on a planet. Starshades also block light and produce clearer photographs of distant planets. Both of these technologies are used with telescopes and provide scientists with enhanced photographs of space. Part of the “Crazy Engineering” series.
The journey of NASA's Cassini spacecraft around Saturn is coming to an end. The Cassini mission has been exploring the Saturn system for nearly 13 years and has rewritten the textbooks on the ringed planet and its moons, but the spacecraft is pretty much out of fuel. However, a lot of work from engineers designed the spacecraft and programmed its flight path, and they used astrodynamics to navigate the spacecraft between the rings of the planet. Part of the "Crazy Engineering" series.
Third in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This third component contains the same "how to" segments from the second in the series (13692) and parts of the history and scientific concepts from the first in the series (13691). However, it also provides greater ease and flexibility in locating, reviewing, and pausing in and between segments than the other two productions in the series. Good for sharing with students to aid them as they build and experiment with kites, gliders, and rubber-band-powered planes.
Biologist Ken Dial has documented in extraordinary detail how birds are put together and the mechanics of how they take to the air. With support from the National Science Foundation, Dial and his team at the University of Montana Flight Lab use x-rays and high speed video to better understand the mechanics of bird flight. Dial’s more than 2,000 flight hours as a pilot in a wide range of aircraft adds another dimension to his research. Perhaps, by mimicking what birds have learned over millions of years, aircraft wings could change shape to accommodate both slow and fast flight, or a helicopter propeller’s shape might be altered to be more efficient.
