Earth and Moon from MESSENGER
(Web Page; Mon Jul 22 19:16:00 CDT 2013)
UPDATE: I've added a neat photo to this post, showing Earth as seen from GOES at the same time and from the same angle. Also check out my post on the "Day the Earth Smiled" picture from Saturn.
Last week, members of the public were aske...
Description: A new picture of the Earth-Moon system from MESSENGER, taken the same day we were told to "Wave at Saturn." Updated with a neat photo taken from much closer to Earth from a similar perspective.
Skimming the inner planets: Updates on MESSENGER and Venus Express
(Web Page; Tue Jun 24 12:53:00 CDT 2014)
The two spacecraft currently orbiting the two innermost planets are both flying low in their orbits in the final phases of their missions. MESSENGER just performed a rocket burn to raise its orbit slightly, while Venus Express did the op...

The MESSENGER spacecraft is headed toward its first of three flybys of Mercury, on January 14, 2008. (It will take three flybys to match its orbital geometry close enough to Mercury's so that it will be able to enter Mercury orbit on Ma...

Galileo Messengers: Cruise to Venus, Earth, Gaspra, Earth, Ida, and almost to Jupiter
(Web Page; Tue Feb 05 10:38:00 CST 2013)
Almost exactly a year ago now, I wrote a post about the Galileo Messengers, newsletters that the Jet Propulsion Laboratory published a few times a year about the Galileo Jupiter mission. That post only covered the first 21 issues, which ...
Description: It's taken me a year to face the emotionally draining task of reading and writing about Galileo's cruise phase as chronicled in the mission's newsletters.
A photo of MESSENGER
(Web Page; Wed Aug 28 18:14:00 CDT 2013)
I was browsing the MESSENGER website just now, and found a neat photo. It's a picture of MESSENGER as seen from Earth when it flew by yesterday. The reason that this photo is neat is that it is exceedingly rare for a planetary spacecraft...

MESSENGER: A snapshot of home
(Web Page; Mon Apr 23 01:35:00 CDT 2012)
MESSENGER is in a unique position in the solar system, orbiting the Sun well within the orbit of Venus. From there, it can gaze outward from the Sun to search for tiny objects that may possibly be traveling in the same region, called vu...

(Web Page; Mon Apr 23 02:02:00 CDT 2012)
...but I can't show you any pictures yet. The MESSENGER mission announced today that the first eight optical navigation images of Mercury have been received on the ground. However, the release didn't actually include the images themsel...
