  space probe — FactMonster.com
Instruments carried by space probes include radiometers, magnetometers, and television cameras sensitive to infrared, visible, and ultraviolet light; there also may be special detectors for micrometeors, cosmic rays, gamma rays, and solar wind.
A probe may be directed to orbit a planet, to soft-land instrument packages on a planetary surface, or to fly by as close as a few thousand miles from one or more planets.
The particulars of trajectory and instrumentation of each space probe are tailored around the mission's scientific and technological objectives; the data provided by a single space probe may require months or even years of analysis.

Unlike an artificial satellite, which is placed in more or less permanent orbit around the earth, a space probe is launched with enough energy to escape the gravitational field of the earth and navigate among the planets.

The Probe must traverse the intense inner radiation belts of Jupiter, which are far stronger than the Van Allen radiation belts about Earth, as it approaches the top of the atmosphere.
The Probe must also be rugged enough to withstand the extreme heat generated by the high-speed plunge into Jupiter’s atmosphere.
Finally, the Probe’s scientific instruments and supporting systems must be able to function at an atmospheric pressure 20 times that of Earth, which the Probe will encounter in Jupiter’s atmosphere.

Stardust is a space mission by NASA that will fly close to a comet and, for the first time ever, bring cometary material back to Earth for analysis by scientists.
The mission is the first by NASA dedicated solely to a comet and the first robotic return of extraterrestrial material from outside the orbit of the Moon.
The main aim of the project is to cross the path of the Wild 2 comet and collect dust particles for analysis in space and to later return the particles to Earth for further investigation.

 Space Probe | World of Earth Science
As distinguished from satellites orbiting Earth under the influence of gravitational attraction, a space probe is rocketed into space with sufficient speed to achieve escape velocity (the velocity needed to obtain parabolic or hyperbolic orbit) and to reach a trajectory aimed at a pre-selected target.
The space probe is used mostly for the acquisition of scientific data enriching general knowledge on properties of outer space and heavenly bodies.
Any space probe is a self-contained piece of machinery designed to perform a variety of prescribed complex operations for a long time, sometimes for decades.

 Europe's space probe swings by Mars | International | Reuters
The pioneering space probe performed its "swing-by" of the red planet early on Sunday, performing the second of four so-called "gravitational assisted maneuvers" that the craft will complete before reaching its ambitious target in 2014.
The three-ton probe successfully orbited Mars close to the controllers' planned trajectory and at one point came within just 250 km (155 miles) of the planet's surface.
Controllers had been concerned the probe might face difficulties as it passed through the Martian shadow, losing the solar power source of its instruments and leaving it reliant on a brace of tiny batteries.

Europe's first space probe to Venus slipped smoothly into orbit on Tuesday in a mission designed to send back data from a planet whose extreme atmosphere conceals important similarities with the Earth.
The last spacecraft on an orbital mission to Venus was NASA's Magellan probe, which orbited the planet from 1990 to 1994 and mapped 98 percent of its surface.
Officials at the ESA's Space Operations Centre in Darmstadt, Germany, said the Venus probe had completed a braking operation that will place it into a position that will allow it to be dragged into orbit around the planet.

The Hayabusa probe, which botched a rehearsal landing earlier this month, was on a mission to briefly touch down on the asteroid, collect material, then bring it back to Earth.
The probe switched to auto-control, storing data about itself and later transmitting it to ground control to be analyzed.
The exact location of the probe was unknown, Horiguchi said, but it was believed to be within 60 miles of the asteroid.

TOKYO -- A Japanese space probe made history on Saturday when it landed on the surface of an asteroid and then collected rock samples that could give clues to the origin of the solar system.
The probe then shot a 5-gramme (0.18 oz) metal ball toward the surface at a speed of 670 mph, collecting into a capsule the debris unleashed as a result of the impact, JAXA officials said.
The probe's capsule containing the samples is due to land in the Australian outback in June 2007.

 SPACE.com -- Gravity Probe B: Delay in Space and Time
Decades in the making, a space probe that delves into Albert Einstein's general theory of gravitation remains grounded on Earth, caught in its own space-time continuum of technical snags, costly delays, and threats of cancellation.
Gravity Probe B is an experiment developed by NASA and Stanford University to precisely test two predictions of Albert Einstein's general theory of relativity, measuring how space and time are warped by the presence of the Earth and how the Earth's rotation drags space-time around with it.
"Gravity Probe B is one of the few space missions NASA has conducted with relevance to fundamental physics," states a 1995 "accelerated scientific review" of the mission undertaken by the Space Studies Board of the National Research Council (NRC).

 Neutron stars steal space probe's glory - 11 September 2004 - New Scientist Space
Gravity Probe B, which carries ultra-sensitive gyroscopes, was conceived in the 1950s to measure these forces, but was only launched in April 2004.
Last week, Ingrid Stairs of the University of British Columbia in Vancouver, Canada, and colleagues reported for the first time that the observed precession in a binary pulsar due to the geodetic effect was consistent with that predicted by general relativity.
So the big prize for Gravity Probe B is now the gravitomagnetic effect, which is hundreds of times weaker than the geodetic effect and is unlikely to be seen in the near future by Stairs's team.
