NICK WALKER:  Welcome to Manage This, the podcast by project managers for project managers.  Every couple of weeks we meet right here and have a conversation about what matters to you in the field of project management.  We talk with real people, doing real jobs, and find out what makes them successful and what keeps them motivated. I’m your host, Nick Walker, and with me are the chief motivators, Andy Crowe and Bill Yates.  And Bill, for those who have ever said that the sky is the limit with what we do around here, well, they may need to rethink that perspective a little. BILL YATES:  Yeah, they’re in for a treat today.  Heather is going to talk to us about the orbital space debris issue that I didn’t even know existed.  This is going to be exciting stuff. Meet Heather NICK WALKER:  We all know how much we rely on satellites in orbit around the Earth.  These provide us with services such as navigation, meteorology, climate research, telecommunication, and human space exploration.  Unfortunately, with increasing space activities, a new and sort of unexpected hazard has started to emerge:  space debris. Dr. Heather M. Cowardin serves as the section manager and project manager for the Orbital Debris Research Section under the Science and Exploration Department of the JETS Contract with NASA Johnson Space Center.  She also leads the NASA Orbital Debris Program Office Research and Development Task Group. Dr. Cowardin, it’s an honor to have you with us here on Manage This.  Can we start out just getting to know you a little bit better?  How did you get to where you are today? HEATHER COWARDIN:  Well, I guess let’s go all the way back a couple of decades and talk about my childhood dream.  I wanted to be Batman, a garbage collector, or an astronaut.  And here we are, a couple decades later, and I feel like I’ve hit at least two of those three points.  I’m a superhero trying to protect space assets in space from garbage.  So not doing too bad. NICK WALKER:  Excellent. HEATHER COWARDIN:  So I guess where I kind of got to from there is I went to space camp in seventh grade after I won a fellowship from the Society of Women Engineers.  I was going to school at University of Houston, got an internship that turned into a full-time job, that turned into basically being a lead, into a deputy manager, into a full-on manager, to here we are now.  So been at NASA a good 15 years. NICK WALKER:  So you’re concentrating on space debris.  I think this is something that maybe escapes the radar of a lot of people. HEATHER COWARDIN:  Aha.  See what you did there. Orbital Space Debris NICK WALKER:  Yeah.  What is orbital space debris? HEATHER COWARDIN:  Right.  So it’s any manmade object that no longer serves a useful purpose.  So what does that mean?  Spent upper stages.  Mission-related debris.  Carriers for multiple payloads.  Even something as small as paint flakes, those can be very damaging. NICK WALKER:  How much of it is there? HEATHER COWARDIN:  There’s about 19,000 objects in space right now that are greater than 10 centimeters.  That threshold is basically the limit of where our sensors can track debris.  But in general there’s probably a good 23,000 or plus that are greater than 10 centimeters, 500,000 that are in the one centimeter range,
