Solar system montage with eight planets

Vesta's wacky craters

Dawn's images of Vesta show craters upon craters, but the longer I study the images, the wackier the craters look.

Mars Exploration Rover

In their own words

While doing my daily reading today I was struck by the awesomeness of two recent blog posts. Both were composed not by professional bloggers like me but by professional space explorers, one a scientist and the other an engineer.

Comet Garradd

Comet Garradd in 3D (sort of)

Amateur astronomer Patrick Wiggins sent me this neat little animation of comet Garradd moving against background stars through an hour's worth of observing. I'm not any kind of astronomer but if I were I think I would get a kick out of looking at things that appear to move within one night of watching -- asteroids, comets, Jupiter's spots. I'm impatient that way.

Opportunity on Endeavour's rim (detail)

Wheels on Cape York!

Opportunity's wheels are on a whole new different kind of rock: she has arrived at the rim of Endeavour crater, on Cape York.

High-resolution global view of Vesta in natural color processed from archival data

Vesta, a revelation

I have to admit it: three months ago I did not understand why space science is important. This is a pretty bold statement coming from a practicing aerospace engineer, but recent events have corrected this lack of understanding, and I am not embarrassed to correct myself in this blog. But let us not get ahead of the story.

Aqua

NASA thinks Earth is a planet, too

Although much of the publicity NASA receives focuses on planetary exploration, Earth observing satellites like Aqua keep tabs on our home planet's weather and climate.

Cassini's group portrait

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.

Vesta's 'Snowman'

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.

Vesta, a whole new world

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.

Jupiter on July 12, 2011 (with bonus Ganymede)

Jupiter's southern belt is coming back

In a story that I've been following for quite a while, Jupiter's southern equatorial belt, having faded to white in 2009, is now well on its way back to its former red glory.

Endeavour's eastern rim, Opportunity sol 2671

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.

Minerals in Mawrth Vallis, Mars

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.
