Comet ISON Enters the Final Countdown
We're now less than two weeks away from comet C/2012 S1 (ISON) reaching perihelion and, if we’re honest, we are still none the wiser as to how the situation might play out!
MAVEN NASA Social: Day 2
Bright and early this morning, we NASA Social folks met at the Kennedy Space Center Visitors Complex for a tour of the space shuttle Atlantis. This is the first shuttle I've seen in person, and it was a stunning sight to see.
Features at both rover field sites on Mars named for Bruce Murray
The Jet Propulsion Laboratory announced today that the geologists on both Mars rover teams -- Opportunity and Curiosity -- have named landmarks at their field sites after the late Bruce Murray.
Just what is going on in that magnificent Cassini image of Saturn?
It took months of work (and no wonder) but the wait was worth it: here is Cassini's spectacular view of Saturn, captured on July 19, 2013, as Cassini passed through Saturn's shadow. If you're a little confused by the image, I'm here to help: I've posted a video explainer.
MAVEN has arrived at the launch pad
As India's Mars Orbiter Mission continues to pump up the altitude of its orbit around Earth, NASA's MAVEN is making final preparations for its direct-to-Mars launch. All is proceeding acccording to schedule toward its November 18 launch at 1:28 EST / 10:28 PST / 18:28 UTC.
Neptune: The new amateur boundary?
Can features on Neptune be observed by amateur astronomers? For years, the Hubble Space Telescope and some professional terrestrial observatories have been revealing incomplete belts and spots on the surface of Neptune. Now, spots have been imaged by amateurs.
The solar eclipse in Africa seen from space
On Sunday, the shadow of the Moon passed across Africa and the Atlantic Ocean. This was the last solar eclipse of the year. The Elektro-L satellite was able to observe the eclipse, and we can see the darkness of the lunar shadow covering Africa.
The Strangest Place on the Moon?
A closer look at the odd lunar feature called
DPS 2013: The fascination of tiny worlds
In which I summarize Joe Veverka's Kuiper Prize talk at the Division for Planetary Sciences meeting:
One for the history books: Stunning Saturn mosaic captured last week by Cassini
I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.
Juno is in Safe Mode again, but still okay
After entering safe mode last week during its Earth flyby, Juno returned to normal operations and downlinked all engineering and science instrument data. It entered safe mode again on Sunday night, but it is expected to re-resume normal operations late next week.
Juno's flying by Earth today, and images of the Moon are already on the ground!
Juno flies past Earth for a gravity assist at 19:22 UTC today, and the first images from the encounter are already on the ground and processed by amateurs!
An Ongoing Odyssey
Twelve years on, Mars Odyssey just keeps sending great images.
On space kindness and the Chelyabinsk meteor
Through an act of kindness, we now have images of the Chelyabinsk meteor trail from Russia's Elektro-L satellite.
Super cool Phobos and Deimos animations from Mars Express
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.
Mars Reconnaissance Orbiter achieves imaging of comet ISON from Mars
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.
Yes, there seems to be a hole in Curiosity's left front wheel, and no, that's not a problem
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.
Swan Song
The final moments of a lunar orbiter, as told in a song composed by the moon itself.
More fancy Phobos and Deimos photography by Curiosity
Curiosity looked up after dark and captured more cool photos of Mars' moons. They include Phobos and Deimos passing in the night, and Phobos entering Mars' shadow.
Two new ways to browse Vesta: 2. Vesta Image data browser
A few weeks ago I received an email pointing me to a really cool new map-based browser to Dawn's Vesta image data.
