Pluto's atmosphere does not collapse

Posted by Emily Lakdawalla on 2013/09/06 11:07 CDT | 2 comments

Just four months ago I posted about a paper recently published by Leslie Young and coauthors that described three possible scenarios for Pluto's atmosphere. Yesterday, Cathy Olkin, Leslie Young, and coauthors posted a preprint on arXiv that says that only one of those scenarios can be true. And it's a surprising one. The title of their paper says it all: "Pluto's atmosphere does not collapse."

By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.

Yesterday, the Curiosity mission released the video whose potential I got so excited about a couple of weeks ago: the view, from Curiosity, of Phobos transiting Deimos in the Martian sky. In this post, Mark Lemmon answers a bunch of my questions about why they photograph Phobos and Deimos from rovers.

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.

How radar really works: The steps involved before getting an image

Posted by Alessondra Springmann on 2013/06/24 02:10 CDT | 3 comments

Arecibo Observatory is known for its 1000-foot diameter telescope and its appearances in Goldeneye and Contact. Aside from battling Bond villains and driving red diesel Jeeps around the telescope (grousing at the site director about the funding status of projects is optional), several hundred hours a year of telescope time at Arecibo go toward radar studies of asteroids.
