Snapshots of Science from the 2014 Lunar and Planetary Science Conference
Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.
Curiosity update, sols 563-569: Kimberley ahoy!
With a series of drives over the last week, Curiosity is now approaching her next science stop at Kimberley. The distinctive knobs of the Kimberley outcrop are visible in photos taken on sol 569.
Curiosity update, sols 549-562: Shooting past Kylie on the road to Kimberley
In a series of drives, Curiosity flew past the
A new map of Mars from some pretty old data
The United States Geological Survey recently issued an improved version of the Viking color map of Mars. This 40-year-old data set still provides the prettiest global-scale map of the planet.
Sand Waves in the Desert
I have a pet peeve: the words dune and ripple are often used interchangeably, although they are quite distinct from one another. So what’s the difference between aeolian dunes and ripples? And why should anybody care?
Curiosity update, sols 540-8: New rules and longer drives
Curiosity has tested a new driving mode -- backwards -- and achieved their longest single-day drive in three months. And they've committed to driving to the spot formerly known as
Curiosity Update, sols 534-540: Over Dingo Gap, onto softer sand
After more than two months of very slow driving due to concern about the wheels and time spent choosing whether to enter
Looking Backward: Curiosity gazes upon the setting Earth
A few days ago, Curiosity looked westward after sunset and photographed Earth setting toward the mountainous rim of Gale crater.
Curiosity update, sols 521-533: Assessing Dingo Gap
While continuing to perform regular wheel health assessments, Curiosity took a sharp right turn and headed for Dingo Gap. On sol 533, they performed a
Beautiful view into the valley beyond Dingo Gap, Curiosity sol 528
A beautiful Mastcam panorama from sol 528 shows a landscape so much more like Earth than anything we've explored on the Martian surface before.
Curiosity update: imaging the nonfunctioning REMS boom, closer to Dingo Gap
At long last, on sol 526, Curiosity imaged the part of the weather instrument that was damaged during landing, but no obvious damage is visible, to me anyway. On sol 527 they drove even closer to Dingo Gap, with plans to drive onto the dune in the sol 528 drive.
Curiosity images "Dingo Gap," sols 519-521
Over the last few days, Curiosity made steady driving progress to the southwest. For several of those days, an intriguing feature has appeared on the horizon in her images. UPDATE: The Curiosity team has now decided to drive the rover toward the feature, which is now named
Curiosity update, sols 488-520: Steady driving while watching the wheels
In the last month, Curiosity put 222 meters on the odometer in 12 short drives, while regularly assessing the wheels for damage. The rover performed touch-and-go analyses of rocks including Oneida and Kodak, and also took some ChemCam RMI mosaics of rocks near the base of Mount Sharp.
What's up in planetary missions in 2014
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
Habitability, Taphonomy, and Curiosity's Hunt for Organic Carbon
Lots of people ask questions about how the Curiosity mission, and future missions, will forge ahead to begin with looking for evidence of past life on Mars. There is nothing simple or straightforward about looking for life.
Curiosity update, sols 465-487: Wheel inspection, software upgrade, Cumberland dump
Curiosity activities over sols 465 to 487 included monitoring the condition of the wheels; a flight software upgrade; and dumping the Cumberland drill sample. Curiosity put approximately 200 meters on the odometer during this period.
Curiosity results at AGU: Gale crater rocks are old, but have been exposed recently
In a Martian first, the Curiosity science team has measured the age of a Martian rock, in two totally different ways. They presented the result at the 2013 meeting of the American Geophysical Union.
Mars' chemical history: Phyllosian, Theiikian, Siderikian, oh my
I'm returning to the deep dive into the literature that began with articles about lunar basins and then explored the geologic time scales of Earth, Moon, and Mars. Now it's time to catch up to the last decade of Mars research and learn what
Curiosity update, sols 453-464: Electrical problem causes delays; rover back to work
An electrical problem frustrated progress on the Curiosity mission this week, but the problem is now understood and the rover back to work.
A post for Reading Rainbow
My brother and I enjoyed watching Reading Rainbow as kids, so it's a delight for me to have had a guest post published on their blog last week. I wrote for them about how kids (with the help of their parents) can follow the adventure of the Curiosity mission through the release of their raw images.
