Mercury Messenger Flyby 1 Summary

MESSENGER has returned quite a few high quality Mercury photographs. Check these out; the surface details are of the side of Mercury the Mariner 10 missions did not photograph!




The cratered surface of Mercury has not been visited in about 30 years. Only 45% of the surface of Mercury has been imaged by the Mariner 10. MESSENGER has a full suite of scientific instruments and will be able to tell us many things about the geological history, and hopefully about the highly reflective material (possibly water-ice in the perpetual shadows) of the north and south poles, of Mercury as well as image the remaining portion of the planet unseen by the previous Mariner mission.

The official MESSENGER website has a slew of great, entertaining, and interactive information pertaining to Mercury. Check it out for some fast facts, great animations, and even an interactive quiz or two to test your Mercurian knowledge.

MESSENGER Now At Closest Point To Mercury

MESSENGER is now at its closest point (about 124 mi) from the surface of Mercury. Now... we wait for the pics!

Today's Mercury Photograph

Tomorrow, the first flyby of Mercury will occur. As you can see, we are quickly approaching the closest planet to the Sun.

MESSENGER Team Receives First Optical Navigation Images

Interplanetary space junkies will have a treat in the next upcoming days: Mercury will be imaged by the MESSENGER spacecraft. In fact, it already has, according to the site: here's the first photo of Mercury by MESSENGER:

The first of eight navigational photos have been received. The spacecraft features two cameras: a wide-angle camera, or WAC, and a narrow-angle camera, or the NAC. To assist in navigation, the WAC takes photos of the starry background, and the NAC, which photographs the planet. Since the stars are so far away, they may as well be 'fixed' in space, and, in conjunction with the planet photograph, are used to determine exact position and if any adjustments need to be made. Stay tuned for more Mercury photographs as they become available!
