The 70-meter dishes of the Deep Space Network

Posted by Emily Lakdawalla on 2011/11/28 05:06 CST

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).

Goldstone: Desert outpost performs radio imaging of close-passing asteroid 2005 YU55

2010 JL33: How to see an asteroid from quite a long way away

Posted by Emily Lakdawalla on 2011/01/13 11:42 CST

A terrific set of Goldstone radar images of a good-sized near-Earth asteroids named 2010 JL33 was posted to the JPL website yesterday. They also posted a movie version but something about these pixelated radar image series absolutely begs for them to be displayed as an old-school animated GIF, so I made one.
