Agricultural engineers explain their work and how they use biology and engineering to make farms energy efficient and the food supply safe and plentiful. They describe what drew them to this profession and also discuss their education and career paths.
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.
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.
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.
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.
A main goal of the 2013 Colombian Engineering Meeting was to gather teachers, students, researchers, professional associations, and the private sector to discuss issues related to engineering. This important event showed technological and theoretical advances of the wide world of engineering.
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.
Figuring ways to clean up contaminated waters is a huge challenge. But luckily, a simple piece of plastic that mimics fish fat can help. Part of the "Science Out Loud" series.
Scientists at MIT's D-Lab are turning trash into treasure. They are using trash to heat homes and cook in developing countries. Part of the "Science Out Loud" series.
Provides an overview of how robots are currently being used and what advances can be expected in the future. Imagine tiny micro bots cleaning a classroom, mini robots retrieving library videos, or a "smart house" that will be automated to take care of an entire family.
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.
Almost fifty years ago the first industrial robot was "employed" in an automobile assembly plant. Robots are regularly used for hazardous, super-heavy and difficult tasks in manufacturing, agriculture, entertainment, medicine, and space exploration. Welding robots with touch sensing and seam tracking abilities increase assembly plant efficiency, while robotic surgery results in less pain, quicker recovery and shorter hospital stays. NASAs robotic rovers Spirit and Opportunity are mapping the terrain and searching for evidence of water on Mars. Honda Motor Company's humanoid robot, ASIMO, can walk, run, recognize people and identify sounds and voices.
The 2013 Colombian Engineering Meeting gathered private sector business and government agencies related to the field of engineering. Some of the areas of focus included alternative energy resources, medicine through TV, basic sciences for engineers, and many other things.
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.
Engineers and architects are creating bridges that combine the best of both art and design. Bridges are no longer just a tool to get from one side of the river to the other. Some bridges have the goal of being aesthetically pleasing and efficient for pedestrians. Others rely on the cantilever design to span a distance equivalent to three and a half jumbo jets. Bridges are often classified by their structure and how the forces of tension, compression, bending, torsion and shear are distributed. Shows how designs vary depending on the function of the bridge, the environmental factors, the materials, and technology used to construct them.
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.
Engineers are motivated to improve our quality of life, and they typically develop new products to achieve this goal. They use several steps in developing new products: design phase, testing phase, and production and maintenance phase. During the design phase, engineers specify the functional requirements of the product. They also produce a prototype to evaluate its overall effectiveness. They also consider cost, reliability, and safety. During the last two phases, engineers determine if any failures of the components are likely and where they occur. In these processes, engineers use computers to create designs, analyze functionality, and simulate how a machine, structure, or system operates.
Explore the dynamic work environment of an electrical engineer who oversees large industrial projects. Watch as engineers interact with one another and use cutting-edge 3-D modeling. Learn how to become a licensed professional engineer. Part of the "Career Connections" series.
Learn how scientists are attempting to enhance apples' defenses through genetic engineering. Viewers learn why it is important for organisms to have a wide variety of genes. Part of "The Botany of Desire" series.
Two MIT students discuss the relationship between photography and science. They use various methods and instruments to explain how long exposure photography can help measure the speed of an airplane, observe the rotation of the earth, or create light paintings.
