I have said very little online yesterday/today about the tragic events that occurred in Connecticut. There are no words that I can say that will bring back the children or even adults whose lives were taken so suddenly and needlessly. I can say nothing that will help make any sense of this truly horrific event. I have no children of my own so I can not even begin to imagine how the parents of the children who were killed must be feeling. I certainly have no words that can console those enduring such a needless loss. I can only hope for those who survive this senseless tragedy that someday, somehow they can find a way to cope with their losses and move forward with their lives however heavy their hearts may remain.

First Image of Mercury From Orbit: "
Early Tuesday morning, NASA’s Messenger spacecraft sent home the first image of Mercury ever taken from orbit around the planet.
The picture, taken at 5:20 a.m. EDT on March 29, shows a wide swath of Mercury’s southern hemisphere. The bright crater at the top of the image is called Debussy, and a smaller crater called Matabei lies to Debussy’s west. The shadowed, pockmarked region south of the bright craters includes Mercury’s south pole and slice of terrain that had never been seen up close before.
When Messenger became the first spacecraft ever to orbit Mercury on March 17, it had already mapped 98 percent of the planet’s surface. But those earlier images were snapped as the spacecraft zipped past to adjust its trajectory. Now that Messenger is in orbit, it will have the chance to explore every crater and crevice of the solar system’s smallest planet in detail.

The wind is no longer at Voyager’s back | Bad Astronomy: "
Voyager 1 is one of the most successful space missions of all time. Launched in 1977, it visited Jupiter and then Saturn, providing better close-ups of the two planets than had ever been seen before.
But it sailed on, crossing the orbits of both Uranus and Neptune (a sister craft, Voyager 2, actually flew by the two planets). Over all those years, there has been one constant in the Voyager flight: the solar wind blowing past it. This stream of subatomic particles leaves the Sun at hundreds of kilometers per second, much faster than Voyager. But now, after 33 years, that has changed: at 17 billion kilometers (10.6 billion miles) from the Sun, the spacecraft has reached the point where the solar wind has slowed to a stop. Literally, the wind is no longer at Voyager’s back.
