MESSENGER at Mercury
2014-08-04 03:15:10

NASA Ten years ago, on August 3, 2004, NASA’s MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft blasted off from Cape Canaveral, Florida, for a risky mission that would take the small satellite dangerously close to Mercury’s surface, paving the way for an ambitious study of the planet closest to the Sun. The spacecraft traveled 4.9 billion miles (7.9 billion kilometers) — a journey that included 15 trips around the Sun and flybys of Earth once,...

Larry Nittler, a staff scientist in the Department of Terrestrial Magnetism of the Carnegie Institution of Washington, has been named deputy principal investigator of the MESSENGER mission. MESSENGER Principal Investigator Sean Solomon, of CIW, delivered the announcement this morning at the first plenary of the 26th meeting of the MESSENGER Science Team meeting in Vancouver, B.C. Solomon, a research scientist and director emeritus at CIW, has led NASA's orbiting exploration of the planet...

This week, MESSENGER's Mercury Dual Imaging System delivered the 100,000th image of Mercury since the spacecraft entered into orbit around the planet on March 18, 2011. The instrument – one of seven aboard the spacecraft – has globally mapped the planet in high-resolution monochrome images and in color images through eight of its color filters, uncovering a new view of Mercury and shedding light on the planet's geologic history. "That our inventory of orbital images of Mercury...

MESSENGER Earns Spot On Discover Magazine's Top 100 Stories Of 2011 List
2011-12-17 05:09:23

Discover magazine has named the MESSENGER mission one of the top 100 stories of 2011. "The 100 stories here capture scientific curiosity in all its stages: provocative early results, long-sought confirmation, and many steps in the iterative process of testing theory against observation and vice versa," wrote Discover Editor-in-Chief Corey Powell in the Editor's Note for the January/February 2012 issue of the magazine. MESSENGER came in at 25 among the 100. This honor caps off a year of...

NASA Extends MESSENGER Mission
2011-11-15 04:32:52

NASA has announced that it will extend the MESSENGER mission for an additional year of orbital operations at Mercury beyond the planned end of the primary mission on March 17, 2012. The MESSENGER probe became the first spacecraft to orbit the innermost planet on March 18, 2011. "We are still ironing out the funding details, but we are pleased to be able to support the continued exploration of Mercury," said NASA MESSENGER Program Scientist Ed Grayzeck, who made the announcement on November...

Mercury and its environment constitute a complex system that includes interactions among the interplanetary medium, the planet's magnetic field, its tenuous atmosphere (or exosphere), and its surface. Mercury's environment includes the solar wind and photon flux (flowing charged particles and light), solar and galactic cosmic rays, and the steady bombardment by micrometeoroids (solar system dust particles). The interactions of these elements of the space environment with the surface generate...

NASA will host a media teleconference at 1 p.m. EDT on Tuesday, March 15, to discuss the first spacecraft to orbit Mercury. NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging, or MESSENGER, will enter orbit at approximately 9 p.m. EDT on Thursday, March 17. The spacecraft has conducted more than a dozen laps through the inner solar system for the past 6.6 years. Media teleconference participants are: -- Andy Calloway, MESSENGER mission operations manager, Johns Hopkins...

The MESSENGER team has just wrapped up a two-week flight test to ensure that the Mercury-bound spacecraft is ready for orbital operations. On March 18, 2011, MESSENGER will become the first spacecraft to enter into orbit about Mercury, embarking on a year-long mission to study in depth the planet closest to the Sun. The completion of this recent test provides a high-fidelity verification of the tools, processes, and procedures that are needed to conduct flight operations at Mercury."Even...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
