No Need to Give Up on Peace in Space

The headlines from this year’s space symposium in Colorado Springs were full of doom and gloom. The U.S. assistant secretary of State for arms control warned, “The threat to outer space is real and growing.” He drew bright lines in the heavens between enemies and allies, dismissed international entreaties for negotiations in the United Nations Conference on Disarmament (UNCD), and called on U.S. allies to strengthen space deterrence.

U.S. Air Force Lt. General Jay Raymond told the packed house of space enthusiasts that China was enemy number one. He claimed a July 2014 Chinese missile defense test was actually an anti-satellite test and that it was successful, although he offered no new information in support of either claim. U.S. officials are using the recent Chinese test to justify greater U.S. reliance on space weaponry to protect U.S. satellites. Read More

Russia’s Small Maneuvering Satellites: Inspectors or ASATs?

In May, Russia announced it had launched three Russian communications satellites, Kosmos-2496, -2497, -2498. An additional object was along for the ride, orbiting a few kilometers away from the declared payloads. Without a declared name, this satellite was subsequently classified as debris by the U.S. space surveillance system. Read More

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.

Disaggregation: Satellite Navigation More Resilient Than You Think

The Pentagon voiced its concern this week that the U.S. GPS navigation capabilities could be held at risk by increasingly capable Chinese anti-satellite capabilities. But it is worth noting that while individual satellites might be threatened, disabling the system and knocking out navigation services is much harder.  Read More

Space Debris, Satellites, and a Reality Check

One strange effect of the seven Oscar wins yesterday for Alfonso Cuarón’s film Gravity is that many more people will be conversant about something that was mostly the kind of thing specialists talked about—just how damaging space debris from anti-satellite (ASAT) weapons can be. In Gravity, astronauts played by Sandra Bullock and George Clooney struggle for their lives after debris from a satellite destroyed on-orbit by Russia threatens the space shuttle and space station.
