Physics Applets, are small flexible Java applets designed for science education.

Physlets, for example the Java applets themselves, are a registered trademark of Wolfgang Christian. 

Physlets are written using Java code that runs on Microsoft, Netscape, and Sun browsers. Unfortunately, Physlets require not only a Java enabled browser, but also JavaScript to Java applet communication. Current Macintosh browsers do not support both Java 1.1 and this communication.

The Physlets listed above were obtained from Davidson College's Physlet web site. Davidson is a nationally recognized, highly selective independent liberal arts college located just outside of Charlotte, North Carolina, in the town of Davidson. Founded in 1837 by Presbyterians, today it enrolls approximately 1600 men and women.

Current Missions
Deep Impact

NASA's Deep Impact spacecraft launched from Cape Canaveral Air Force Station, Fla., on Wednesday, January 12, 2005. The mission will travel to a comet and release an impactor on July 4, 2005 creating a crater on the surface of the comet. Scientists believe the exposed materials may give clues to the formation of our solar system.

Mars Exploration Rover Mission

NASA's twin robot geologists, the Mars Exploration Rovers, launched toward Mars on June 10 and July 7, 2003, in search of answers about the history of water on Mars.

The Mars Exploration Rover mission is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet.

Hubble Space Telescope

The Hubble Space Telescope is an operational program that continues to generate major scientific discoveries. New science instruments were delivered and installed on-orbit via the space shuttle in 2000 and 2003. HST's instruments provide scientific data in the ultraviolet, visible, and near infrared regions of the electromagnetic spectrum. (Launched 1990 April 24)


The Cassini Mission will do a detailed study of Saturn, its rings, its magnetosphere, its icy satellites, and its moon Titan. The Cassini Orbiter's mission consists of delivering a probe (called Huygens, provided by the European Space Agency) to Titan, and then remaining in orbit around Saturn for detailed studies of the planet and its rings and satellites. Cassini will arrive at Saturn on 2004 July 1. (Launched 1997 October 15)

Deep Space 1

Deep Space 1 launched from Cape Canaveral on October 24, 1998. During a highly successful primary mission, it tested 12 advanced, high-risk technologies in space. In an extremely successful extended mission, it encountered Comet Borrelly and returned the best images and other science data ever from a comet. During its fully successful hyperextended mission, it conducted further technology tests. The spacecraft was retired on December 18, 2001.


The Galileo spacecraft was designed to study Jupiter's atmosphere, satellites, and surrounding magnetosphere. The spacecraft was named in honor of Galileo Galilei, the Italian Renaissance scientist who discovered Jupiter's major moons in 1610. The spacecraft was launched on October 18, 1989 and arrived on December 7, 1995.

The Galileo spacecraft's 14-year odyssey came to an end on Sunday, Sept. 21, 2003 when the spacecraft passed into Jupiter's shadow then disintegrated in the planet's dense atmosphere at 11:57 a.m. Pacific Daylight Time. The Deep Space Network tracking station in Goldstone, Calif., received the last signal at 12:43:14 PDT. The delay is due to the time it takes for the signal to travel to Earth.

Mars Global Surveyor

Mars Global Surveyor became the first successful mission to the red planet in two decades when it launched November 7, 1996, and entered orbit on September 12, 1997. After a year and a half trimming its orbit from a looping ellipse to a circular track around the planet, the spacecraft began its prime mapping mission in March 1999. It has observed the planet from a low-altitude, nearly polar orbit over the course of one complete Martian year, the equivalent of nearly two Earth years. Mars Global Surveyor recently completed its primary mission on January 31, 2001, and is now in an extended mission phase.

The mission has studied the entire Martian surface, atmosphere, and interior, and has returned more data about the red planet than all other Mars missions combined.

Mars Odyssey

2001 Mars Odyssey is an orbiting spacecraft designed to determine the composition of the planet's surface, to detect water and shallow buried ice, and to study the radiation environment. Launched on April 7, 2001 and arrived on October 24, 2001.


Stardust is a comet sample return mission having the distinction of being the first sample return mission from beyond the Earth-Moon system. Stardust will collect interstellar dust, then encounter Comet P/Wild 2 in 2004 collecting comet dust and possibly imaging the nucleus at resolutions 10 times better than Giotto did at Halley, and return to Earth in 2006 (returned Jan. 15, 2006) to drop off the sample return capsule. (Launched 1999 February 7)

New Horizons

As the first spacecraft to visit Pluto and its moon Charon, New Horizons looks to unlock one of the solar system's last, great planetary secrets. After launch aboard an Atlas V in January 2006, the New Horizons spacecraft will cross the entire span of the solar system and conduct flyby studies of Pluto and its moon, Charon, in 2015. The seven science instruments on the piano-sized probe will shed light on the bodies' surface properties, geology, interior makeup and atmospheres.

Gravity Probe B

Gravity Probe B (GP-B) is a relativity gyroscope experiment developed by NASA and Stanford University to test two extraordinary, unverified predictions of Albert Einstein's general theory of relativity. GP-B will measure how space and time are warped by the presence of the Earth, and, more profoundly, how the Earth's rotation drags space-time around with it.

GP-B was launched on April 20, 2004 out of Vandenburg Air Force Base.
