"En route to the Moon, approximately 200,000 miles (320,000 km) from Earth, Mission Control asked Swigert to turn on the hydrogen and oxygen tank stirring fans, which were designed to destratify the cryogenic contents and increase the accuracy of their quantity readings. Approximately 93 seconds later, just under 56 hours since launch, the astronauts heard a "loud bang", accompanied by fluctuations in electrical power and firing of the attitude control thrusters.[6] The crew initially thought that a meteoroid might have struck the Lunar Module (LM)."

"The United States Navy airships U.S.S. Akron (ZRS-4) and U.S.S. Macon (ZRS-5) were designed for long-range scouting in support of fleet operations. Often referred to as flying aircraft carriers, each ship carried F9C-2 Curtiss Sparrowhawk biplanes which could be launched and recovered in flight, greatly extending the range over which the Akron and Macon could scout the open ocean for enemy vessels."

"Flight Club Become a future aerospace engineer! Have fun learning, building, and experimenting with paper airplanes, helicopters, parachutes, rockets, and a wide variety of aerospace designs. This class will assist you in becoming a master paper airplane mechanic and foster building skills that will last a lifetime. This class is both interactive and educational with an emphasis on building and having fun with things that fly."

"Visual or sonic, real or virtual, our experiences are a constant interface with key algebraic concepts like proportional and inverse relationships, graphical representations of slope, arithmetical functions, and independent and dependent variables. Design Zone: Behind the Scenes is a brand-new exhibit created by OMSI that makes math fun by directly connecting mathematical concepts to real-life experiences like hip-hop, art, skate parks, and more."

SMILE is collecting the best educational materials on the web and creating learning activities, tools, and services - all designed especially for those who teach school-aged kids in non-classroom settings.

"Pathway To Engineering | High School Engineering Program - The PLTW Pathway To Engineering (PTE) program is a sequence of courses, which follows a proven hands-on, real-world problem-solving approach to learning. Throughout PTE, students learn and apply the design process, acquire strong teamwork and communication proficiency and develop organizational, critical-thinking, and problem-solving skills."

"Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. "

"augmented reality app that labels all the stars, constellations, and satellites you point your iPhone at. You can track the ISS, find out what constellation you've been looking at from your bedroom window and get a lot of exciting and educative information. Combine that with the amazing Apple Design Award winning graphics and highest quality content, "

Call for Experiments: Student Spaceflight Experiments Program (SSEP) Mission #3 to ISS The National Center for Earth and Space Science Education, in partnership with NanoRacks, invites school districts across the U.S. to participate in the SSEP program. An 8-week competition in your school or district, held Fall 2012, will allow grades 5-12 students to engage in real scientific research of their own design. The selected submissions from across the country will then be flown on each community's previously reserved mini-lab slot on ISS.

"America's first experimental space station, Skylab, was designed for long durations. Skylab program objectives were twofold: To prove that humans could live and work in space for extended periods, and to expand our knowledge of solar astronomy well beyond Earth-based observations. The program was successful in all respects despite early mechanical difficulties."

"The "Supersonic bi-directional flying wing" has wings of alternating length at each compass point and therefore can solve both situations, by taking off in one orientation, then essentially flying sideways when it's time to go supersonic. I'd like to see video of how this happens in motion, but from what I can see in the stills, it looks like the dual engines up top determine the direction of flight, and that the rest of the plane rotates around them. "

"This site offers a growing bank of imaginative, highly visual teaching-aids developed for use with interactive whiteboards in 11-18 Schools. The resources are designed to be used as rich sources of visually stimulating material, making use of both animations and drag and drop interactivity. The appropriate Key Stage is indicated for each resource. "

"Engineering and fun aren't always two things that kids naturally associate with one another, but there are hundreds of ways to make engineering, physics and design fun and challenging for kids. Here are 100 great experiments that will let kids construct, play, learn and grow, all while they study the fundamentals of engineering."

"Boeing Sonic Cruiser is a new aircraft that is being built by Boeing Commercial Airplanes. Boeing is aiming to develop a design that will allow commercial passenger and cargo aircraft to fly faster, higher and farther travel. The airplane will travel at Mach 0.95 or faster. It is estimated that it will save about one hour for every 3,000 miles flown. The only commercial aircraft to travel faster is the Concorde."

"The Air Camper was designed to be built of spruce and plywood. One of Pietenpol's goals was to create a plane that was affordable and easy to construct for home builders. Building an Air Camper requires basic woodworking skills and tools. Builders also need to fabricate some metal fittings to attach the wooden parts together. Some welding is required. The plans for the Pietenpol Aircamper were originally published in a four part serial in the "Flying and Glider" Manual of 1932-33"

"Chevak students and family members gathered in brisk conditions to watch as the Rans S-6S Coyote took flight over the tundra, after receiving its airworthiness inspection and certification. The aircraft was built by Chevak High School students as part of an aviation course offered by the school located on the tundra in western Alaska. "The aircraft was beautifully built and was obviously the pride of the aeronautics class at the school," said Designated Airworthiness Representative (DAR) John Davis."

"Amelia Rose Earhart says she "knew" after taking a first flight lesson in 2004 that she and her famous ancestor had more than a name in common. Now a private pilot training for an instrument rating, Earhart launched Dec. 26 on the first legs of a flight designed to recreate some of the milestones that led up to Amelia Mary Earhart's 1937 attempt to encircle the globe. "

"Students can learn some science concepts just as well from computers simulations as they do from direct observation, new research suggests. See Also: Mind & Brain Educational Psychology Language Acquisition Space & Time Moon Pluto Computers & Math Computer Modeling Computer Science Reference Computer simulation Instructional design Computing power everywhere Local area network A study found that people who used computer simulations to learn about moon phases understood the concepts just as well -- and in some cases better -- than did those who learned from collecting data from viewing the moon."

NROC's Developmental Math-An Open Program is designed for students striving to meet college entrance requirements. The program offers video, audio, interactive simulations, puzzles, and other instructional approaches that engage a variety of learning styles and attitudes as learners work to close proficiency gaps.

"In the future, a swarm of flying robots may do the work now done by human search teams. A robotics research team at the University of Pennsylvania has designed a system to coordinate a number of small quadcopters, a step toward coordinating multiple robots for tasks such as surveillance or searching areas after a disaster.
