The 70-meter dishes of the Deep Space Network

Emily Lakdawalla • November 28, 2011

I was inspired by my recent trip to Goldstone to put together this poster showing all three of the great 70-meter dishes of the Deep Space Network. There's one at each of the three complexes, at Goldstone, at Robledo (near Madrid, Spain), and at Tidbinbilla (near Canberra, Australia).

Earth science's next big thing

Jason Davis • September 22, 2011

Meet the next big thing in NASA's mission to study planet Earth: NPP, the NPOESS Preparatory Project satellite.

Video: Soaring over Earth

Emily Lakdawalla • September 19, 2011

This amazing video has already been posted by basically every other space blogger but I can't resist featuring it too, especially because I just realized that it was not made by NASA but instead by a member of the public digging into public NASA archives of image data -- yay for amateurs!

Scale solar system presentation slide, a provisional version for you to review

Emily Lakdawalla • September 15, 2011

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

Pretty picture: Earth and Moon from JunoCam

Emily Lakdawalla • August 30, 2011

It's always awe-inspiring to see our great world as just a tiny spot within vast space. The latest spacecraft to get such a view of Earth and the Moon is the Jupiter-bound Juno.

NASA thinks Earth is a planet, too

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.

Citizen Science projects for Planetary Science: Get Involved! Do Science!

Mike Malaska • May 12, 2011

Citizen Science projects let volunteers easily contribute to active science programs. They're useful when there is so much data it overwhelms computing algorithms (if they exist) or the scientific research team attempting to process it.

A rare direct hit from a meteorite

Emily Lakdawalla • May 09, 2011

Meteorites hit Earth all the time, but they almost never score direct hits on human-built structures (or humans, for that matter). Once in a while, though, direct hits do happen, and it looks like this recent event in Poland was the real thing.

Familiar yet alien ancient views of Earth

Emily Lakdawalla • May 04, 2011

I have always found maps of the motions of Earth's continents fascinating, so it is really cool to see some gorgeous new reconstructions of what Earth would have looked like to spaceborne observers over the last 750 million years.
