MOFFETT FIELD, Calif.--In a festival that is now celebrated in various forms around the world to recognize the 50th anniversary of cosmonaut Yuri Gagarin's first human journey into space, more than 6,000 students from around the Bay Area visited NASA's Ames Research Center here for Yuri's Education Day.

With games, a scavenger hunt, and tours of a supersonic F-104 Starfighter, NASA opened its hangar doors to foster the spirit of exploration and education.

The 205-pound space shuttle tires are filled with nitrogen because of the gas' stability at varied altitudes and temperatures; they are inflated to 340 psi.

The main landing gear shuttle tires are only used one time, and are rated to a speed of 263 mph.

Lined up along the tarmac, students from Bay Area schools lined up to peek inside this F-104 Starfighter.

Originally a fighter plane, this Starfighter has been used by NASA as a research chase plane, and was last used in 1994.

NASA outfitted this specific plane with a belly camera, which was used in testing to conduct research into different visual landing aids for spacecraft use.

Geoff Chiu operates a robot made using a Motorola phone, showing how cell phones can contribute to the field of robotics.

Chiu says cell phones are an ideal base for a starting point in robotics. Cell phones (essentially small computers and integrated transmission systems) are relatively inexpensive, advanced computers which have already been built with many of the components needed for a robot, including cameras, compasses, GPS, communications systems, and reliable power supply.

Standing among hundreds of children waiting in line this morning along the barbed fences of NASA Ames, one of the more talked-about destinations inside was the "space toilet."

In the weightless environment of space, the collection of liquid and solid waste is directed by the use of air flow, which is filtered and then returned to the cabin.

Novice spaceflight group Spacebridge designs and and builds cheap and easy DIY systems for launching instruments and cameras into the stratosphere.

A sort of model rocketry for adults, here we see one of Spacebridge's systems, which was launched, tracked, and recovered in Northern California.

In addition to the F-104 Starfighter, an H-60 Black Hawk helicopter, and a C-130 Hercules turboprop from the California Air National Guard, the fire crews at NASA Ames brought out some of their equipment including the Crash 10 emergency response vehicle, shown here.

Visible light and electromagnetic radiation are just two of the many types of electromagnetic energy produced by objects throughout the universe.

Only by studying all of these types of radiation can we characterize celestial objects and gain a complete picture of the universe's history and evolution.

At this booth, NASA describes how the Stratospheric Observatory for Infrared Astronomy (SOFIA), based on a Boeing 747SP wide-body aircraft, uses an infrared telescope to look into space.
