A different face of Vesta (oh, *there's* the craters!)
Here's the latest image release from Dawn at Vesta, taken from an altitude about twice as high as that of their first mapping orbit.
Origins 2011 conference, part 2
In this, my second blog on Origins 2011 in Montpellier, France, a conference dedicated to the interdisciplinary research on the origins of life, I aim to provide my impression of the second half of the conference.
Pretty movie: Everything in the Saturn system is in motion!
A few weeks ago a producer for a public television space documentary asked me if I knew of any cool Cassini animations and my answer was,
Dawn Journal: Dawn has arrived!
After covering 2.8 billion kilometers (1.7 billion miles) on its own, after traveling for nearly four years through the lonely emptiness of interplanetary space, after being bound by the gravity only of the sun, Dawn is finally in orbit around Vesta.
It's official now: Curiosity is going to Gale
The news leaked a few weeks ago has turned out to be true: the next Mars rover, Curiosity, will be headed for Gale crater on Mars when it launches at the end of this year.
Vesta does a Hyperion impression
Maybe it's my own peculiar variant of pareidolia, but every time I see a new image of Vesta I'm reminded of some different other lumpy body in the solar system. In the image released just now by the Dawn team, taken from 10,500 kilometers away, I'm seeing Hyperion.
Opportunity's horizon rises -- and maybe brings Cape York into view
For miles and miles of Martian terrain, Opportunity's view forward has contained a distinctive line of hills—the far rim of Endeavour crater.
A fourth moon for Pluto
That's right: Hubble observations have yielded the discovery of a third small body orbiting Pluto and Charon.
Vesta in infrared color!
Yet another sharp-eyed reader (I love my readers!) pointed out to me that the German-language release on the MPS website about the latest Vesta image from Dawn included what looked like a tiny thumbnail of a color view.
Congratulations to the Dawn team on their orbit entry & pretty pictures!
There's a new orbital mission on the map! As of Friday, the relatively small mass of the asteroid Vesta has finally taken hold of its new artificial satellite, Dawn.
Yet another new image of Vesta
A sharp-eyed reader noticed that a size comparison montage posted by the Dawn mission today included an image of Vesta that had not yet been released separately to the public, and it is a very cool one.
Origins 2011 conference, part 1
The Origins 2011 conference, which took place last week in Montpellier, France, was dedicated to the origins of life and its occurrence in the universe. At this meeting, scientists from very different disciplines came together to share their ideas.
Summary of the fifth MSL landing site selection meeting
Well, after three days of fascinating science and heated discussion, the fifth and final MSL landing site workshop has come to a close, and the consensus is -- that all of the sites are pretty darn interesting.
Hubble's Millionth Observation
The Hubble Space Telescope has recorded its millionth observation. The planet is designated HAT-P-7b.
Ever closer to Vesta
Here's a photo of Vesta that was released by the Dawn team on Friday. I didn't post it right away because the version of the image in the official release has some bizarre processing artifacts that make it look as though the image had been made by cutting construction paper.
Cassini animations: Rhea and Dione and Titan
I've been mucking about in the Cassini data archives (as I often do when procrastinating) and unearthed a neat, if short, mutual event sequence of two crescent moons passing by each other.
Amateur takes on the Dawn Vesta images
I am pretty sure that the Dawn team put nearly every image they've taken of Vesta so far in the animation they released yesterday, which is awesome. It hasn't taken long for the amateur image processing community to pick that animation apart into its component frames and process the heck out of the individual images to produce some very fine looking images and animations.
Vesta looks pretty battered
There was a press briefing on Dawn today at NASA Headquarters, and there are new pictures! Here's what Vesta looked like as of three days ago, when Dawn was only 189,000 kilometers away.
The most exciting citizen science project ever (to me, anyway)
A guest blogger here recently rounded up the large number of participatory research projects that are collectively known as citizen science. I think these are all very cool and I encourage you to check them out but none of them has yet inspired me to spend my precious time as grunt labor on a gigantic collective project. Until now.
Cassini finally catches Helene
Cassini has finally achieved gorgeous global imaging of Helene with a spectacular flyby on Saturday, in which they got Helene to pose prettily for the camera from beginning to end of the encounter. And what a wacky, wacky world Cassini has revealed Helene to be!!
