Experts Say Much More Required to Avoid Satellite Collisions, Space Debris

Senate and House committees held hearings on consecutive days last week about space situational awareness (SSA) and space traffic management (STM), i.e., the ability to accurately track objects in Earth orbit and to avoid dangerous collisions that could knock out satellites and even render entire orbits unusable.

The overall conclusion was that, although progress is being made, we’re not nearly as aware as we need to be as orbital debris poses an ever bigger problem and companies prepare to launch tens of thousands of new satellites.

“Near Earth space is geo-politically contested, it’s commercially contested and it’s in dire need of environmental protection because it is a finite resource,” said Moriba Jah, an associate professor of astronautics at the University of Texas.

House Space Subcommitee’s Surreal NASA Budget Hearing

I woke up early this morning with a low-grade headache. Checking Twitter, I discovered I’d slept through the beginning of a House Subcommittee on Space’s hearing on NASA’s budget with Administrator Charlie Bolden.

My headache immediately worsened as I found the hearing webcast on my cell phone. A whole range of largely unprintable words and phrases came immediately to mind, but there was one that kept coming back: clown car. The House Science Committee really needs a bigger clown car.

It’s not the committee members’ criticism of the Boulder (sorry, Asterorid) Redirect Mission that I had a problem with. Or their demands that NASA actually present a road map to help guide the nation on the road to Mars. I even understood why they felt the Obama Administration’s request for Space Launch System (SLS) and Orion was low. And the Europa mission probably needs more money. All those things are the subject of legitimate debate.
