Home is Where the Stars are

Michael Bomburg spends his nights skateboarding at a local park, playing Halo online with friends and preparing dinosaur chicken nuggets for dinner – his routine resembles that of any normal human.  But by day, Michael fills a role that many only dream of: he’s a rocket scientist.

Q: Growing up, what interested you about space?

A: I think that it’s the idea of the unknown and what that does for my imagination.  There’s a mystery about outer space that you can’t find on Earth. Earth just seems so familiar, and the curtains are so easy to pull back that it kills the imagination. The preconceived notions of a place on earth can be confirmed or shattered by stepping on a plane or opening a book. But the universe is so large and the possibilities so endless that it lets the imagination run wild.

Q: Before applying to college, did you need to show that you were capable of being an “aerospace engineer”?

A: No, the college application process was pretty superficial. Though, I believe that capability is based on passion – passion for the subject matter is why I excelled.

Q: Did you have an internship while you were in college?

A: I interned at the NASA Langley Research Center. NASA does a great job at letting your creativity drive a design or concept.  In that sort of environment, new ideas are fostered much better than in the private industry. One thing I was told there that always stuck with me is “it’s everyone else’s job to tell us why something is impossible, and it’s our job to show them why they are wrong”.

Q: Where did you land after you graduated?

A: My first job was as a propulsion engineer – which involves designing ways to propel satellites – at a company called Space Systems Loral in California. “Propulsion engineer” is one of those positions where you wear a lot of hats.  Some days I was at a desk improving some of our daily responsibilities, but a few weeks out of the year I worked mission control during satellite orbit launches.  But now I’ve now moved on from that job and work as a quality assurance engineer in Europe.  This position exposes me to far greater number of our spacecraft parts with new sets of problems to solve.

Q: How does it make you feel knowing that your work is being used?

A: What I do helps to make the world smaller. What I mean by this is that everyone is able to talk to friends and family on the other side of the planet without any delay because of the technology that I support.  I think that’s pretty neat.

Q: Down the road, where do you see yourself?

A: Ideally, somewhere in deep space. Otherwise I would like to be an active participant in manned spaceflight programs, Mission Director would be nice.

Gaia’s Trip Across the Milky Way

On December 19, 2013 at the Guiana Space Centre, the ESA launched Gaia, a 32-foot satellite destined to trek 1 million miles of uncharted territory in space while surveying more than a billion stars.  Nearly a month after its launch, Gaia arrived at the second Lagrangian (L2) where it could continue its mission—to assemble a digital map of our home galaxy, the Milky Way.  For the next five years, Gaia will scan the Milky Way, making about 40 million observations each day.

Before Gaia started scanning the stars, the satellite had to go through a set of procedures to test its programs.  Putting together a map of an entire galaxy is not an easy task, so the Kourou Project Team must confirm that all systems run smoothly by finding and fixing any issues.  In February, the team found that external sunlight was unexpectedly bending around Gaia’s sunshield and entering its protective thermal vent.  The Kourou Project Team couldn’t have found this error at a better time because it would affect Gaia’s ability to measure fainter stars.  As a solution, the team proposed to tilt the shield slightly to eliminate stray light.

So what will this map tell us about our cosmic neighborhood?  When Gaia’s mission is complete, there will be 1 petabyte of data – enough to fit on 200,000 DVDs!  This information will help scientists piece together a picture of the Milky Way’s formation and composition.  The data Gaia gathers allows researchers to learn in-depth details about each star like its brightness, temperature and chemical makeup.  Scientists hope that with Gaia’s help, they will discover new space objects in our territory—exoplanets, comets, icy bodies, and possibly even distant supernovae.  Who knows what astronomers will find years from now, looking back through Gaia’s massive database armed with a generation’s worth of data and knowledge about our galaxy.
