LAUREL, Md. - On Monday, Jan. 14, a pioneering NASA spacecraft will be the first to visit Mercury in almost 33 years when it soars over the planet to explore and snap close-up images of never-before-seen terrain. These findings could open new theories and answer old questions in the study of the solar system. The MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft, called MESSENGER, is the first mission sent to orbit the planet closest to our sun. Before that orbit...

ESA's Venus Express and NASA's MESSENGER booked an appointment at Venus late in the evening of 5 June, to look at the oddities of this mysterious planet in tandem for a few hours. Just a few weeks on, scientists from both teams are ready to present a first set of images. This unique opportunity to make multi-point observations of the Venusian atmosphere was possible thanks to the MESSENGER (MErcury Surface, Space ENvironment, Geochemistry, and Ranging) swingby of Venus "“ a key step...

Picture this: A spaceship swoops in from the void, plunging toward a cloudy planet about the size of Earth. A laser beam lances out from the ship; it probes the planet's clouds, striving to reach the hidden surface below. Meanwhile, back on the craft's home world, scientists perch on the edge of their seats waiting to see what happens. Sounds like science fiction? This is real, and it's happening today. The spacecraft is MESSENGER, and the planet is Venus. On June 5, 2007, MESSENGER will fly...

On June 6 this year, scientists all around the world will be watching with eager eyes as not one but two spacecraft observe Venus simultaneously. ESA's Venus Express, in orbit around Venus since 11 April 2006, will be joined for a few hours by NASA's MESSENGER (MErcury Surface Space ENvironment GEochemistry and Ranging mission), flying by Venus while on its way to Mercury. Earth-based observatories and telescopes in orbit around Earth will also be watching. Looking at Venus together,...

Researchers working with high-precision planetary radars, including the Goldstone Solar System Radar of NASA's Jet Propulsion Laboratory, Pasadena, Calif., have discovered strong evidence that the planet Mercury has a molten core. The finding explains a more than three-decade old planetary mystery that began with the flight of JPL's Mariner 10 spacecraft. The research appears in this week's issue of the journal Science. Launched in Nov. 1973, Mariner 10 made three close approaches to Mercury...

BepiColombo, ESA's mission to explore planet Mercury, has been definitively 'adopted' by the Agency's Science Programme Committee (SPC) last Friday. The mission will now start its industrial implementation phase, to prepare for launch in August 2013. BepiColombo is the next European planetary exploration project, and will be implemented in collaboration with Japan. A satellite 'duo' "“ consisting of an orbiter for planetary investigation and one for magnetospheric studies "“ will...

Mark your calendar: On Wednesday, Nov 8th, the planet Mercury will pass directly in front the Sun. The transit begins at 2:12 pm EST (11:12 am PST) and lasts for almost five hours. Good views can be had from the Americas, Hawaii, Australia and all along the Pacific Rim: visibility map. What will it look like? A picture is worth a thousand words: During the transit, Mercury's tiny disk"”jet black and perfectly round"”will glide slowly across the face of the Sun. Only a speck of the...

NASA's Mercury-bound MESSENGER spacecraft came within 2,990 kilometers (1,860 miles) of the surface of Venus early this morning during its second planetary encounter. The spacecraft used the tug of the planet's gravity to change its trajectory significantly, shrinking the radius of its orbit around the Sun and bringing it closer to Mercury. MESSENGER swung by Venus at 8:34 UTC (4:34 a.m. EDT), according to mission operators at the Johns Hopkins University Applied Physics Laboratory (APL) in...

Mercury makes a rare appearance in the evening sky this week. NASA -- It's not every day you get to see a shrinking planet. Today could be the day. Step outside this evening at sunset and look west toward the glow of the setting sun. As the sky fades to black, a bright planet will emerge. It's Mercury, first planet from the sun, also known as the "Incredible Shrinking Planet." "This is only the second time in my life I've seen Mercury," says sky watcher Jeffrey Beall who snapped this picture...

NASA -- The pictures from MESSENGER's Aug. 2 flyby of Earth are in "“ and they are spectacular! The collection includes "natural" color and infrared views of North and South America; a peek at the Galapagos Islands through a break in the clouds; and a movie of the rotating Earth, taken as MESSENGER sped away from its home planet. The close flyby of the Earth and Moon allowed the MESSENGER spacecraft to give its two cameras, known as the Mercury Dual Imaging System (MDIS), a thorough...

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...
