Juno is on the way to Jupiter!
It almost looked like it wasn't going to happen today, but it did! At 16:25 UTC, a huge Atlas V 551 lifted off with the Juno spacecraft and sent it on its way to Jupiter.
Junocam will get us great global shots down onto Jupiter's poles
Juno is a mission that will peer deeply into Jupiter's interior, and didn't really need to take a visible-light camera along in order to accomplish its scientific goals. But I think nobody could bear sending a spacecraft to Jupiter without getting pictures from up close. So they added Junocam.
Fun for the whole family: Watch an enormous rocket blast a spacecraft to Jupiter!
Do you have kids at home for the summer? Treat them to a spectacular fireworks show by tuning in tomorrow morning to watch Juno blast off to Jupiter!
Pretty picture: five moons for Cassini
Explaining how to combine the red, green and blue images from a recent Cassini image session containing five of Saturn's moons: Janus, Pandora, Enceladus, Mimas and Rhea.
What I see in the first high-res Dawn images of Vesta
I had to wait until the kids were in bed and the husband fed last night before I finally had time to sit down and really look at the Dawn images of Vesta. And I still hardly knew where to begin. This brand new world is just so different than others I've seen.
On speculation in today's Dawn press briefing
When a spacecraft has visited a new body for the first time, the usual answer to any scientific question is
Fabulous Dawn Vesta images and rotation movie!!
Now that Dawn's close enough to Vesta, we're seeing absolutely spectacular detail and tremendous diversity across Vesta's surface. As usual it'll probably take me a while to bring together all the new information, so as a stopgap I'm going to post an awesome image and a rotation movie.
Mountains rising for Opportunity
The views from Opportunity of Endeavour's near and distant rim peaks are getting ever more vertical as Opportunity approaches Cape York.
Mars Exploration Rovers Update: Opportunity Closes in on Endeavour as Team Bids Farewell to Spirit
Opportunity seemed to sail with the wind behind her back toward the western rim of Endeavour Crater this month as the Mars Exploration Rover team shifted gears in preparation for a whole new adventure, taking time out only to bid a final farewell both privately and publicly to Spirit.
Phobos-Grunt and Yinghuo-1 have completed thermal vacuum testing
The Russian Phobos sample return mission, Phobos-Grunt, has passed a key milestone in its preparation for launch: it successfully completed its thermal vacuum testing in June.
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.
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.
Planetary Society Statement on the Pioneer Anomaly
Planetary Society Members have been supporting Slava Turyshev and his colleagues in their scientific quest to solve the famous Pioneer Anomaly. They have just published a peer-reviewed paper that reports on what may be the last step toward the solution.
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.
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.
