NASA re-creates the Apollo 8 Earthrise using Lunar Reconnaissance Orbiter data

Posted by Andrew Chaikin on 2013/12/20 02:20 CST | 1 comments

Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.

Posted by Vitaliy Egorov on 2013/11/05 11:35 CST

On Sunday, the shadow of the Moon passed across Africa and the Atlantic Ocean. This was the last solar eclipse of the year. The Elektro-L satellite was able to observe the eclipse, and we can see the darkness of the lunar shadow covering Africa.

A few days ago, I wrote a post about the basins of the Moon -- a result of a trip down a rabbit hole of book research. Here's the next step in that journey: the Geologic Time Scales of Earth and the Moon.

Beautiful science by Elektro-L

Posted by Vitaliy Egorov on 2013/08/08 03:54 CDT | 7 comments

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

Posted by Emily Lakdawalla on 2013/07/23 05:03 CDT | 15 comments

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.

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.

Dunes on Tatooine

Posted by Ralph Lorenz on 2013/07/17 01:13 CDT

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.

Stationkeeping in Mars orbit

Posted by Emily Lakdawalla on 2013/06/27 10:55 CDT | 10 comments

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

Posted by Jim Bell on 2013/06/03 03:53 CDT | 6 comments

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!
