A NASA spacecraft's third and final flyby of Mercury gives scientists, for the first time, an almost complete view of the planet's surface and provides new scientific findings about this relatively unknown world. The Mercury Surface, Space Environment, Geochemistry and Ranging spacecraft, known as MESSENGER, flew by Mercury on Sept. 29. The probe completed a critical gravity assist to remain on course to enter into orbit around Mercury in 2011. Despite shutting down temporarily because of a...

NASA will host a media teleconference at 1 p.m. EST on Tuesday, Nov. 3, to announce scientific findings and release new images from the third and final flyby of Mercury by the Mercury Surface, Space Environment, Geochemistry and Ranging spacecraft, known as MESSENGER. The probe's cameras and instruments collected high-resolution and color images of the planet on Sept. 29, unveiling another six percent of Mercury's surface never before seen by a spacecraft. The briefing participants are: -...

COLUMBIA, Md., Oct. 2 /PRNewswire-FirstCall/ -- On September 29, NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft, more commonly referred to as "MESSENGER," flew within 142 miles of Mercury's surface. This was the spacecraft's third and final flyby of the planet. Designed, built, managed, and operated by the Johns Hopkins University Applied Physics Laboratory (APL) for NASA's Science Mission Directorate, MESSENGER is scheduled for a 2011 insertion into...

U.S. scientists say the Messenger spacecraft turned off its instruments during a highly-anticipated flyby of the planet Mercury, limiting data collection. Mission systems manager Eric Finnegan said the space probe shut down its instruments after detecting a problem during the last of three scheduled Mercury flybys, but a wealth of information was collected prior to the shutdown, The Baltimore Sun said Thursday. It isn't the outcome everyone expected or wanted, Finnegan said of Tuesday's...

NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument, will make its third and final flyby of Mercury on Sept. 29 -- a clever gravity-assist maneuver that will steer it into orbit around the rocky planet beginning in March 2011. The spacecraft will zip within 142 miles of the planet's surface at more than 100,000 miles per hour on Sept. 29, taking high-resolution color images of the surface terrain. MESSENGER also will be making ultraviolet...

NASA's Mercury Surface, Space Environment, Geochemistry, and Ranging spacecraft known as MESSENGER will fly by Mercury for the third and final time on Sept. 29. The spacecraft will pass less than 142 miles above the planet's rocky surface for a final gravity assist that will enable it to enter Mercury's orbit in 2011. Determining the composition of Mercury's surface is a major goal of the orbital phase of the mission. The spacecraft already has imaged more than 90 percent of the planet's...

NASA will host a media teleconference at 1 p.m. EDT on Wednesday, Sept. 23, to preview the third and final flyby of Mercury by the Mercury Surface, Space Environment, Geochemistry, and Ranging spacecraft known as MESSENGER. On Sept. 29, the spacecraft will swing less than 142 miles above the planet's rocky surface for a final gravity assist that will enable it to enter orbit around Mercury in March 2011. With more than 90 percent of the planet's surface imaged after the spacecraft's second...

In less than two weeks, on September 29, MESSENGER will fly by Mercury for the third and final time, a maneuver key to placing the probe on a trajectory that will enable its March 2011 insertion into orbit about Mercury. Even as the team readies for this critical event, a parallel effort has long been underway to prepare MESSENGER for the main event. Since January, the team has been staging orbital operations rehearsal tests, called week-in-the-life (WITL) tests, to try out the new procedures...

On September 29, the MESSENGER spacecraft will pass by Mercury for the third time, flying 141.7 miles above the planet's rocky surface for a final gravity assist that will enable it to enter orbit about Mercury in 2011. This encounter will also provide new observational opportunities for MESSENGER's Magnetometer, designed to determine the structure and origin of Mercury's intrinsic magnetic field. The comparison of magnetosphere observations from MESSENGER's first flyby in January 2008 with...

The Planet Mercury -- in astronomy, nearest planet to the sun, at a mean distance of 36 million mi (58 million km); its period of revolution is 88 days. Mercury passes through phases similar to those of the moon as it completes each revolution about the sun, although the visible disk varies in size with respect to its distance from the earth. Because its greatest elongation is 28, it is seen only for a short time after sunset or before sunrise. Since observation of Mercury is...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
