Caution: Spacecraft Under Construction

Mat Kaplan • August 20, 2013 • 1

Join Emily Lakdawalla and Mat Kaplan inside JPL's High Bay 1, where two Earth-revealing missions are being readied for launch.

Beautiful science by Elektro-L

Vitaliy Egorov • August 08, 2013 • 7

Six months ago, I wrote about the Russian weather satellite Elektro-L, which has more than two years of successful experience in the geostationary orbit. Then I promised that I would be here to share the materials that we collected. I think it's time to deliver on the promise.

Pretty picture: Looking backward

Emily Lakdawalla • July 23, 2013 • 15

Here it is: the view from Saturn of our Earthly home, one and a half billion kilometers away. We see Earth and the Moon through a thin veil of faintly blue ice crystals, the outskirts of Saturn's E ring. Earth is just a bright dot -- a bit brighter than the other stars in the image, but no brighter than any planet (like Saturn!) in our own sky.

Earth and Moon from MESSENGER

Emily Lakdawalla • July 22, 2013 • 3

A new picture of the Earth-Moon system from MESSENGER, taken the same day we were told to "Wave at Saturn." Updated with a neat photo taken from much closer to Earth from a similar perspective.

Return of the Pale Blue Dot

You can be part of a planetwide group photo as Cassini and MESSENGER turn their cameras Earthward on July 19.

Dunes on Tatooine

Ralph Lorenz • July 17, 2013

The fictional world Tatooine, scene of action in the Star Wars movies, is named after a town in Tunisia, where parts of the movies were filmed. The desert backdrops against which the movies were filmed are real terrestrial landscapes, which prove to be perhaps unexpectedly dynamic.

A rare clear day in Alaska

Emily Lakdawalla • July 12, 2013 • 3

NASA recently shared a gloriously detailed image of an unusual clear day in Alaska as seen from the Terra satellite.

Stationkeeping in Mars orbit

Emily Lakdawalla • June 27, 2013 • 15

It had never occurred to me to think about geostationary satellites in Mars orbit before reading a new paper by Juan Silva and Pilar Romero. The paper shows that it takes a lot more work to maintain a stationary orbit at an arbitrary longitude at Mars than it does at Earth.

One Ocean World Among Many

Jim Bell • June 03, 2013 • 6

I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!

No Place Like Home

Bill Dunford • April 21, 2013 • 6

Mars and Earth share a truly striking family resemblance, but there's no mistaking which one is home.
