The NASA spacecraft MESSENGER has spent over 6.5 years traveling to the planet Mercury. On March 17, 2011, it will enter an orbit about Mercury, the first time any human-made probe has successfully done so in the history of space exploration.

The highly successful mission of the first commercial spacecraft to be launched into orbit about Earth and safety returned home was completed on December 8, 2010. SpaceX is proud of its accomplishment, with images and information for you to enjoy.

The first commercial spacecraft to launch into orbit and return home safety carried a kinda top-secret payload. The heads of SpaceX let the 'payload'-out-of-the-bag on Thursday, informing everyone what was inside the Dragon spacecraft.

The mission of NASA’s Kepler spacecraft was to look for Earth-sized planets out there in space. Astronomers got a pleasant surprise when the spacecraft added exciting new information to astroseismology, the study of the internal structure of pulsating stars.  

NASA’s newest probe to study the Sun was launched on Thursday, February 11, 2010, after the winds subsided and the weather cleared over the Florida launch pad at the Cape Canaveral Air Force Station.

The NASA website "What Do You Think?" features numerous accomplishments made by the U.S. space agency NASA in 2009 in order to help all peoples of Earth to learn more about our world and the worlds of our Solar System and the Universe. What do you think is the top accomplishment?

Two NASA Voyager spacecraft are flying near the edge of the solar system. According to U.S./Russian scientists, the spacecraft have discovered that the 'solar system is passing through an interstellar cloud that physics says should not exist.'

The U.S. space agency NASA has confirmed that its STEREO spacecraft has recorded "monster waves on the sun known as 'solar tsunamis'." These monster waves were thought not to exist on the Sun, but NASA says they are real.

At first, spectators and NASA scientists were disappointed that a debris plume was not visible as the LCROSS spacecraft imaged its Centaur rocket impacting the Cabeus crater on the Moon. However, now, enhanced crash images show a 1-mile high plume did occur—much shorter than the 12-mile plume predicted.

THE NASA spacecraft IBEX is making a map of the edge of the heliosphere, the magnetic boundary formed by the solar wind and interstellar matter at the edge of the solar system. Unexpectedly, IBEX imaged a "bright, winding ribbon of unknown origin" that goes about 80% away around the solar system.
