Martian clouds in motion
Behold an amazing (if I do say so myself) video of Martian clouds in motion.
Gale's not the only Martian crater with an "enigmatic mound"
Much has been made of the
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.
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.
Spirit Point and Odyssey crater in sight, and new rock under Opportunity's wheels
Opportunity is at her goal. In this 3D anaglyph, taken on sol 2678 (yesterday, August 6, 2011), Opportunity's wheels are resting on strange lumpy bedrock.
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.
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.
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.
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.
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.
Update: Phobos and Jupiter and its moons!
Remember that neat picture and movie of Phobos passing by Jupiter that I posted last week? Several people asked me where Jupiter's moons were, and I just assumed that they weren't visible. I was wrong; Mars Express spotted Jupiter's moons along with the planet and Mars' moon!
Watching Phobos pass by Jupiter
Here is a really cool view of Phobos in the foreground with gigantic (but very distant) Jupiter sitting in the background, a fortuitous alignment that the Mars Express High-Resolution Stereo Camera team took advantage of on June 1.
Europa on the Ropes
For now, Mars continues to eclipse Jupiter's moon Europa (shown here to scale) in NASA's flagship mission plans, but not in its appeal to many planetary scientists.
Summer Sights of the Solar System
What can you expect to see if you look at the night sky this summer (2011)?
Zapping Rocks for Science
Laser beams and space exploration are perfect for each other, and not just because all self-respecting starship captains know their way around a blaster. It turns out that zapping rocks with a laser is not only fun, it also can tell you what they're made of!
A picture of Spirit that's too poetical for words
Yesterday, I remarked that despite the declaration of her death we'll be seeing Spirit frequently over the next few years, as long as Mars Reconnaissance Orbiter is still monitoring her landing site with its HiRISE camera. I said that Spirit is a lump that's relatively easy to spot because of her dark shadow. Well, Spirit's managed to make herself even easier to spot than that.
It's opposite day at the Curiosity landing site selection meeting
I've been attending the final Mars Science Laboratory Landing Site Community Workshop meeting this week, taking copious notes for a future article in The Planetary Report, some of which I'll post here when I get a chance. But I just had to write a brief post about the totally crazy role reversal that is going on at this meeting.
Memo to early risers: Look up!
There is a traffic jam of planets on the eastern horizon in the early morning right now and for the next several weeks, a prize for those of you who have to rise before dawn.
The scale of our solar system
Space.com has taken advantage of the infinitely scrollable nature of Web pages to produce a really cool infographic on the scales of orbital distances in the solar system.
