My ever-popular asteroids-and-comets montage, now in color, with bonus Toutatis

Emily Lakdawalla • December 18, 2012

My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.

Chang'E 2 imaging of Toutatis succeeded beyond my expectations!

Emily Lakdawalla • December 14, 2012

The Chang'E 2 mission flyby of Toutatis succeeded in acquiring images. Oh my goodness, did they succeed. These, in combination with the incredible radar images still being acquired from Goldstone and innumerable optical observations, make Toutatis one of the best-studied asteroids in the solar system.

How GRAIL will meet its end

Emily Lakdawalla • December 13, 2012

The twin GRAIL spacecraft are nearly out of fuel, and are being directed to a controlled impact near the north pole on the near side of the Moon on December 17. Before the end, though, they did some cool things, including flying within 2000 meters of mountaintops, and catching video of Lunar Reconnaissance Orbiter in flight.

Isostasy, gravity, and the Moon: an explainer of the first results of the GRAIL mission

Emily Lakdawalla • December 11, 2012

Last week the GRAIL mission published their first scientific results, and what they have found will send many geophysicists back to the drawing board to explain how the Moon formed and why it looks the way it does now. To explain how, I'm going to have to back way up, and explain the basic science behind gravity data.

Reviews of nonfiction book series for children

Emily Lakdawalla • December 10, 2012

More than you probably wanted to know about Curiosity's SAM instrument

Emily Lakdawalla • November 30, 2012

With all the hoopla surrounding the unknown results of the first analysis of a soil sample by Curiosity's Sample Analysis at Mars (SAM) instrument, I thought an explainer would be useful. What is SAM, what is it designed to measure, and what is the nature of its results? Here you go.

SMBC on NASA announcements

Emily Lakdawalla • November 29, 2012

Zach Weiner of Saturday Morning Breakfast Cereal critiques NASA's announcement style.

Water ice and organics at Mercury's poles

Emily Lakdawalla • November 29, 2012

Water ice at Mercury's poles? That's crazy, right? The MESSENGER team has made a very good case that radar-bright material seen by the Arecibo telescope is, in fact, water ice, covered in most places by a veneer of dark organic material.

That amazing image of Saturn's north pole just got better: now, it moves!

Emily Lakdawalla • November 28, 2012

Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

Curiosity news that's not news (or maybe it is), and some thoughts on art and science

Emily Lakdawalla • November 20, 2012

This morning while driving to work I heard a terrific story about Curiosity on National Public Radio from Joe Palca, NPR's science correspondent. It was a great story despite the fact that it contained virtually no news. The nugget of non-news is that SAM's analysis of Mars soil has yielded some unspecified, exciting, but not-yet-confirmed result. But that's not really what Palca's story is about.

Curiosity sol 102 update: Eppur si muove

Emily Lakdawalla • November 19, 2012

Curiosity is a rover again at last! She was parked at the dune named Rocknest for 40 sols, from sol 60 through 99. On sol 100, she drove right on top of the dune, obliterating her five scoop marks. Then on sol 102 she took a good long, 35-meter drive so that she's now right on the edge of the "high thermal inertia unit" that attracted her to the spot the team has named Glenelg.

Dawn Vesta Data is publicly available (for real this time!)

Emily Lakdawalla • November 16, 2012

After a false start earlier this year, the first chunk of Dawn Framing Camera data from Vesta has finally made it to the Planetary Data System. As a first step to understanding the data set, I've built some index pages to these cool images.
