Pretty Cassini pictures from near the ring plane
It's been a while since I posted some Cassini pictures here just because they were pretty.
Analyzing the first published Huygens results
I am working my way steadily through the seven Huygens papers that were released by Nature magazine Wednesday on their
Cassini Photographs the Fountains of Enceladus (and gets pics of Tethys, Janus, Epimetheus, and the G ring too)
Emily tackles this morning's ESA press conference about Huygens.
Thruster trouble for Hayabusa
Hayabusa has been riding an incredible wave of luck lately, resulting in the dramatic success of the sample grab last week. But it looks as though Hayabusa's luck may be running out.
Big News for Hayabusa: It wasn't hovering, it landed!!
Remember how Hayabusa was virtually still for 30 minutes? JAXA is now saying that Hayabusa actually touched down -- and more than that, they may even have a sample.
A fun picture for holiday travel
A fun NASA explainer just crossed my email inbox and I thought I'd share it.
Closer still to Itokawa
Hayabusa reached an altitude of about 560 meters above Hayabusa at 17:30 UTC. And at 18:00 UTC they are at 500 meters. This is still farther above the asteroid than the asteroid is big...there is still a long way to go before Hayabusa touches down...
A gap in the Hayabusa telemetry, as the Earth rotates
If I understand the various sources(and my somewhat vague memory) correctly, it now appears that Earth has rotated far enough to take the Deep Space Network station at Goldstone, through which Hayabusa has been transmitting, out of line with Hayabusa.
Getting ready for Hayabusa's touchdown
In a further update on Hayabusa's status, we have been contacted by Kazuya Yoshida of the Space Robotics Laboratory at Tohuku University. Yoshida reports that the touchdown is now planned to take place
Another Hayabusa update: small delay
There has been a delay of just about a day in JAXA's plans for landing Hayabusa on Itokawa.
A couple of Hayabusa updates
Tak Iyori from The Planetary Society of Japan has sent us a couple of updates on the status of Hayabusa and the mission's plans for landing on Itokawa.
Amazing Hayabusa images
These photos pretty much speak for themselves. They are amazing. Hayabusa saw its own shadow on Itokawa, and took a photo of the released target marker.
An update on the Huygens Doppler Wind Experiment
While I was at the Division of Planetary Sciences meeting in Cambridge in September I had a chance to chat with David Atkinson, who's a member of the Doppler Wind Experiment team on Huygens. They and the other instrument teams have been plugging away at analyzing their data.
Europe Prepares to Return to Venus
After a 2-week delay in its schedule, the European Space Agency's Venus Express spacecraft is back on track for launch.
Cassini Poised to Pinpoint Huygens' Landing Site At Last
I've just posted a very brief update on the upcoming Titan flyby, which will be the first to include RADAR imaging across the Huygens landing site.
An evening with Dava Sobel
I've just come home from Caltech, where I saw author Dava Sobel give a presentation on her latest book, The Planets.
NOW Mars is spectacular
Back in August, there was a false alarm being circulated by email that Mars was going to be super-close to Earth on August 27.
A way-cool Cassini picture: rings, Titan, Dione, Prometheus
I just noticed this picture on the Cassini raw images website. I love these
Animation from Cassini's approach to Dione
The images from Cassini's Dione encounter yesterday have started coming back, and there is a really cool set of 16 pictures of Dione and Rhea.
Dione encounter today
Cassini is already on its way in to a close, 500-kilometer encounter with Dione -- it's less than four hours away now, at 17:52 UTC.
