A recent tweet by Al Yankovic tipped me to the fact that the children's book author, songwriter, and illustrator Sandra Boynton recently established a presence on Twitter. As I'm a huge fan of her oeuvre, I immediately followed her.

Japan's Venus climate orbiter Akatsuki failed to enter orbit in December 2010 when a clogged valve caused catastrophic damage to its main engine. Since then, JAXA's engineers and navigators have determined that although the main engine is a total loss, there is the possibility of achieving Venus orbit on a future encounter, using only the attitude control rockets.

Roscosmos, the Russian Space Agency, has released its official report concerning the failure of the Phobos-Grunt spacecraft, which fell back to Earth from orbit on January 15 after failing to ignite the engines that were to take it to the largest Martian moon.

As Opportunity worked away on its winter science campaign, the Mars Exploration Rover mission quietly completed its eighth Earth year of exploring the surface of the Red Planet last week, and is now roving on into Year 9 of its 90-day mission.

Since the last log, the robotic explorer Dawn has devoted most of its time to its two primary scientific objectives in this phase of the mission.

Before automated space observatories like SDO could send pictures and videos of solar phenomenon in real-time, humans had to do it manually, as in the case of the groundbreaking Skylab space station missions, which featured the Apollo Telescope Mount.

Those of you who follow me on Twitter know that after beginning with Dawn last week, I've kept my fingers busy, stitching more spacecraft from plastic canvas. I now have prototypes for GRAIL, New Horizons, and MESSENGER.

The Cosmos Award for Public Presentation of Science -- at least the blown-glass Saturn trophy given to Stephen Hawking by The Planetary Society -- continues to appear around the Internet.

On February 24, 2007, the Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long route to a 2014 rendezvous with comet Churyumov-Gerasimenko. At the time, they released two photos from the main science camera, OSIRIS.

At the end of last week, a rather sensational article appeared in both the Russian- and English-language sites of the Russian news agency, RIA Novosti.

From 1981 to 1997, the Galileo mission published an approximately quarterly newsletter called the Galileo Messenger. It eventually ran to 45 issues, until the end of the Prime Mission. The first 20 were published before Galileo ever got off the ground. That period is the subject of this post.

This week's lineup is a largely astronomical crowd so most of the conversation concerned dark matter and boiling exoplanets and imaging the black hole at the center of our galaxy.
