A notice of some new names for features on asteroid 2867 Steins inspired me to dig up the data set from the September 5, 2008 Rosetta flyby and explore it to see what it contained.

NuSTAR, the most sensitive X-ray telescope ever developed, launched successfully at 16:00 UT. This was a fun launch to watch, because the launch vehicle was a Pegasus XL air-launched rocket, dropped like a bomb from open bay doors of an L-1011 airplane.

The stage is set for China’s space program to make history this weekend, as it prepares to send three taikonauts to visit Tiangong-1, the country’s first space station.

Sky & Telescope and Replogle Globes teamed up to take advantage of the fabulous new Lunar Reconnaissance Orbiter image mosaic of the Moon to make an equally fabulous new Moon globe.

There was good news and bad news in this morning's press briefing about Curiosity rover's upcoming landing on Mars, just eight weeks from now. First, the good news: the landing ellipse has shrunk. The bad news: there's a contamination problem with the drill, and the Odyssey orbiter is in safe mode.

Glen Nagle pointed me to two awesome papercraft models of the Curiosity rover that you can download and -- assuming you have a LOT of patience and a steady hand -- assemble.

When amateurs process NASA images, can they hold copyright over them? Yes, sometimes. Andrew Rush of IPinspace.com explains the law.

The National Reconnaissance Office has donated two, partially-completed space telescopes to NASA, revealed at a National Academies' Committee on Astronomy and Astrophysics meeting this week.

On June 6 I hosted the Cosmoquest Weekly Science Hour. My guest was Dan Durda of the Southwest Research Institute. We talked asteroids, impact mitigation, searches for Vulcanoids, and suborbital experiments, and then he took us through how he creates his digital space art.

Bill Nye

Thank you Ray; you changed the world. At the Planetary Society we will do our best to see to it that your dreams and hopes of exploring the distant regions of the Solar System, Mars especially, and are kept alive.

Ray Bradbury passed away last night, June 5, 2012, at the age of 91. He was a friend to the Planetary Society and an inspiration to its members. We'd like you members to share your recollections and stories of his singular influence in your lives.

Mars rover driver Scott Maxwell relates a story of how he handed Ray Bradbury an opportunity to drive on Mars.

The last words Ray said to me were, “Yes, I will shout HURRAH!” I was visiting him at his home and had spent a hour or so talking with him about our favorite subject, Mars, as well as reading to him a couple of his own poems. Yesterday he passed away at the age of 91.

Telescope maker Celestron joined the Planetary Society at April's big festival in Washington. Their new video about the experience features our Emily Lakdawalla.

Since you last visited, Opportunity has continued to drive downhill – well, what passes for ‘downhill’ on Cape York! – and is now not far at all from the northern edge of the Cape. From where she is now she sees the Meridiani desert stretching away to the north and west, the eastern hills on her right, and the Cape itself behind her. And around her? lots and lots of Homestake-like gypsum veins.

Dawn is beginning its departure from Vesta, spiraling upward from its low-altitude mapping orbit to a higher one from which it will map north polar terrain not visible during the earlier mapping orbit.

Unless you are lucky and healthy enough to live for another 105 years, tomorrow will be your last chance to see a Venus transit from the surface of the Earth. But this need not be the last transit of Venus that you will ever see.
