Visualizing the UCS Satellite Database

Quartz created an interactive visualization using the UCS Satellite Database data called “The World Above Us: This is every active satellite orbiting the earth.” It shows all the satellites in the database, with their image size proportional to their launch mass, set in altitude bands. You can pull up relevant details on each satellite, and set them in motion. You can highlight different populations (spy sats, type of user, etc.)

It’s a real pleasure to see someone take your work (in this case, primarily the work of Database researcher Teri Grimwood) and make something beautiful and useful from it.

Missile Defense: Taking the Path of Least Resistance

Huntsville, Alabama is full today with champions of ballistic missile defense from the political, military, and industrial spheres, braving the south in August for the 2014 Space and Missile Defense Conference.  So far, I haven’t heard any reports about the specific next steps for the Ground Based Midcourse (GMD) missile defense system, although from other sources, it looks like the Pentagon might be taking June 22’s successful intercept test with a little too much exuberance.

Comments on the Ground-Based Midcourse Missile Defense Test Record

The Department of Defense states that Sunday’s test was the 65th successful hit-to-kill intercept out of 81 tries since 2001 for the Ballistic Missile Defense System. This statistic includes not only the Ground Based Midcourse (GMD) missile defense system tested this weekend, but all ranges of interceptors, including the Patriot system which targets short range missiles.

Only 17 of those tests have been of the GMD system. The Missile Defense Agency (MDA) will state the GMD record as 9 successes out of 17 tests, which includes tests of interceptors that were prototypes and those with both the CE-I and CE-II kill vehicles. The Pentagon also claims “four intercepts using the operationally configured interceptor since 2006.” Read More
