Team members at NASA's Jet Propulsion Laboratory share the challenges faced during the final minutes before “Curiosity” landed on the surface of Mars. “Curiosity” is a car-sized robotic rover exploring Gale Crater on Mars as part of NASA’s Mars Science Laboratory mission (MSL).

How can honeybees communicate the locations of new food sources? Austrian biologist, Karl Von Frisch, devised an experiment to find out. By pairing the direction of the sun with the flow of gravity, honeybees are able to explain the distant locations of food by dancing. The scientists at Georgia Tech University explain the design of Von Frisch's famous experiment and describe the precise grammar of the honeybees dance language with new computer vision techniques. They hope the research into behaviors of social insects will aid in the design of better systems of autonomous robots.
In the conquest of space today, it is robots, not humans, who get the glory. Describes missions that represent the foreseeable future in space exploration: sensor-filled craft and remotely operated devices going where people can't. The program features Deep Impact, a comet-blasting probe; Cassini-Huygens, pioneer of Saturn's moon, Titan; Robonaut, a machine designed to perform human tasks; Ranger, a huge mechanical spider that could conceivably repair the Hubble Space Telescope; the Hubble itself, aging but carrying on; and the planned Webb Space Telescope, Hubble's eventual successor on the vanguard of deep-space science.
Mendelvium is a radioactive metal of the actinide series. It does not occur naturally and was first made in 1955 by bombarding einsteinium with helium ions.

With support from the National Science Foundation, aerospace engineer Michael Philen and his team at Virginia Tech are investigating the biomechanics of fish locomotion, in hopes of contributing to the next generation of robotic fish and underwater submersibles. They’re studying how fish use their muscles to swim efficiently and execute underwater maneuvers, such as darting around in perfectly synchronized schools. They’re also developing new smart materials, such as a bioengineered hair that is modeled after the hair cell sensors on the side of fish that allow it to detect minute changes in water flow. Part of the National Science Foundation Series “Science Nation.”
A shark attack survivor now knows what it feels like to be part bionic man. 23-year-old amputee Craig Hutto has volunteered to help test a state-of-the-art prosthetic leg with powered knee and ankle joints. With support from the National Science Foundation and continued support from the National Institutes of Health, Vanderbilt University mechanical engineer Michael Goldfarb has spent several years developing the leg, which operates with special sensors, an electric motor, a battery, and computer technology. Sensors monitor the user's motion and microprocessors figure out what the person is trying to do. Goldfarb says the powered leg reduces the lag time between a real leg and a prosthetic one. Hutto confirms that the powered prosthetic is much better at anticipating his next move.
Cyborg technology is a revolutionary development in rehabilitation medicine. It allows the brain and nervous system to manipulate specially engineered devices that help people regain the use of impaired body function. Once a dream of science fiction, this revolutionary technology is now becoming a reality. Demostrates a deep brain stimulation that can help stop the violent shaking of victims of Parkinson's disease. Presents two professors from the State University of New York and Duke University who discuss their cutting-edge research.
