Latest Mercury spacecraft Stories
As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius).
WASHINGTON, April 30 /PRNewswire-USNewswire/ -- A NASA spacecraft gliding over the surface of Mercury has revealed that the planet's atmosphere, the interaction of its surrounding magnetic field with the solar wind, and its geological past display greater levels of activity than scientists first suspected.
Data from a U.S.
NASAâ€™s live media teleconference held earlier today included a panel of experts working on the US space programâ€™s MESSENGER instrument that discussed new data and findings revealed by the planet Mercuryâ€™s makeup.
NASA will host a media teleconference on Thursday, April 30, at 2 pm EDT to discuss new data and findings revealed by the Mercury Surface, Space Environment, Geochemistry, and Ranging spacecraft known as MESSENGER.
MESSENGER completed the second part of a two-part deep-space maneuver today, providing the remaining 10% velocity change needed to place the probe on course to fly by Mercury for the third time in September 2009.
A NASA spacecraft gliding over the battered surface of Mercury for the second time this year has revealed more previously unseen real estate on the innermost planet.
NASAâ€™s Mercury Messenger passed within 200km of the planet on Monday collecting about 1,200 new images.
Yesterday, at 4:40 am EDT, MESSENGER successfully completed its second flyby of Mercury, and its cameras captured more than 1,200 high-resolution and color images of the planet â€“ unveiling another 30 percent of Mercuryâ€™s surface that had never before been seen by spacecraft.
MESSENGERâ€™s engineering and operations teams convened at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., Sunday afternoon to confirm the health and readiness of the spacecraft.
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...
