I've been delving in to the Mars Express image archive this week, checking out its images of Phobos, and found a couple of really cool time-series of images to assemble into animations.

Today I received my furlough notice from NASA. Since my job isn’t considered “excepted,” in other words, since no one will be injured or die if I don’t report for work, then I am to remain at home until recalled to work after the Congress passes and the President signs some sort of budget or continuing resolution to keep the government running.

Launch preparations will resume for NASA's MAVEN spacecraft, due to launch to Mars on November 18th. Work had previously been suspended, potentially causing the spacecraft to miss its once-every-26-month launch opportunity.

Several Indian news sites posted a press wire article this morning indicating that India's Mars Orbiter Mission departed its assembly and testing facility in Bangalore today and is now on the way to the coastal launch site, the Satish Dhawan Space Centre at Sriharikota, a journey of about 400 kilometers.

Yesterday, the much-anticipated comet ISON made its closest pass by Mars. Mars Reconnaissance Orbiter's HiRISE camera is the first to achieve a positive detection of the somewhat-fainter-than-expected comet in its photos.

When LADEE launched on September 6, it launched into Earth orbit. Today, it is finally on a path that will take it to its October 6 lunar orbit insertion. Its operation is continuing normally in the face of the U.S. government's shutdown yesterday, as is that of Lunar Reconnaissance Orbiter.

Some brand-new images just arrived from Curiosity on Mars, and two of the most recent are Mars Hand Lens Imager (MAHLI) images of the wheels. Today's images contained two little surprises.

A few days ago, I wrote a post about the basins of the Moon -- a result of a trip down a rabbit hole of book research. Here's the next step in that journey: the Geologic Time Scales of Earth and the Moon.

On the sixth anniversary of leaving Earth to embark on a daring deep-space expedition, Dawn is very, very far from its erstwhile planetary residence. Now humankind's only permanent resident of the main asteroid belt between Mars and Jupiter, the seasoned explorer is making good progress toward the largest object in that part of the solar system, the mysterious dwarf planet Ceres.

With the recent announcement by NASA that the 36 year-old spacecraft Voyager 1 has officially entered interstellar space at a distance from the sun about four times further than Neptune's orbit, and with Voyager 2 not far behind, it seems worthwhile to explore how humans managed to fling objects so far into space.

The Voyagers were special when they launched. They have become more so thanks to their longevity, the breadth of their discoveries, the cultural payload they carried, and the sheer audacity of their quest.

We're two weeks in to ‘Dancing with the Stars’ season 17, and Bill Nye has shown that, true to his TV-theme song lyric,
