The first spacecraft designed by NASA to orbit Mercury is giving scientists a new perspective on the planet's atmosphere and evolution. Launched in August 2004, the Mercury Surface, Space Environment, Geochemistry and Ranging spacecraft, known as MESSENGER, conducted a third and final flyby of Mercury in September 2009. The probe completed a critical maneuver using the planet's gravity to remain on course to enter into orbit around Mercury next year. Data from the final flyby has revealed the...

It's not easy practicing for something no one has done before, but the MESSENGER team is giving it a go. Mission and science operators have wrapped up the third and fourth in a series of rehearsals for how the spacecraft will be operated once it is in orbit about Mercury. "No spacecraft has orbited Mercury before; although the spacecraft has been operating since 2004 and has flown past Mercury three times, team members have no direct experience planning and scheduling daily science...

The solar system's innermost planets are about to put on a beautiful show. This week, Mercury is emerging from the glare of the sun and making a beeline for Venus. By week's end, the two planets will be just 3o apart, an eye-catching pair in the deep-blue twilight of sunset. The best nights to look are April 3rd and 4th. Go outside at the end of the day and face west. Venus pops out of the twilight first, so bright it actually shines through thin clouds. Mercury follows, just below and to the...

One year from today "” starting at 12:45 a.m. UTC "” MESSENGER will transition from orbiting the Sun to being the first spacecraft ever to orbit the planet Mercury. "We are finally closing in on the most intense phase of the mission," says MESSENGER Principal Investigator Sean Solomon, of the Carnegie Institution of Washington. "MESSENGER's six and a half years of interplanetary flight are a long warm-up for the main event, when we are in orbit about Mercury. The final year of...

Teachers from across the U.S. are invited to apply to become Educator Fellows for NASA's MESSENGER mission to Mercury. The 30 master teachers chosen for the program will receive special training to help them conduct teacher training workshops featuring lessons for grades pre-K to12 developed in support of the mission. "Our Educator Fellowship Program greatly expands the reach of the MESSENGER Education and Public Outreach Team," says MESSENGER Principal Investigator Sean Solomon. "Many of our...

Today the MESSENGER spacecraft crossed the four-billion-mile mark since its launch. The probe has completed about 81 percent of its journey toward its destination to be the first spacecraft inserted into orbit about Mercury. That MESSENGER's odometer reading has reached another major milestone reminds us of the long and complex route that our spacecraft must follow. Mercury orbits deep within the Sun's gravity well. So, even though the planet can be as close as 82 million kilometers (51...

NASA's MESSENGER mission team and cartographic experts from the U. S. Geological Survey have created a critical tool for planning the first orbital observations of the planet Mercury "“ a global mosaic of the planet that will help scientists pinpoint craters, faults, and other features for observation. The map was created from images taken during the MESSENGER spacecraft's three flybys of the planet and those of Mariner 10 in the 1970s. A presentation on the new global mosaic is being...

The MESSENGER spacecraft has been named one of Time magazine's best 50 inventions of 2009. The NASA probe, built by the Applied Physics Laboratory (APL) in Laurel, Md., came in at number 11. Here is what the editors had to say in the November 23 issue of the magazine: "If the solar system has a flame-roasted planet, it's Mercury, where the sun pushes surface temperatures to 800°F (426°C). That brutal environment is one reason no NASA probe has visited Mercury since 1975. But Messenger...

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...
