This week in space: Fat Milky Way, 3-D Supernova, NASA's Administrator, Runaway Stars, Wearable Toilet.

With Fermi, astronomers will at long last have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds.

A recap of events at NASA for the week ending January 9, 2009.

GRACE, twin satellites launched in 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity & Earth's natural systems. These discoveries could have far-reaching benefits to society & population.

A mission that was supposed to last no more than six months, the twin rovers are now celebrating their 5th year on Mars. Innovation, excellent engineering and incredible scientific results are the legacy of Spirit and Opportunity.

The Mars Exploration Rovers "Spirit" and "Opportunity" were sent to Mars for what was planned to be a 90 day mission. 5 years later they are still roving the surface of Mars, making new discoveries almost every day.

The Galaxy Evolution Explorer (GALEX) is an orbiting space telescope observing galaxies in ultraviolet light across 10 billion years of cosmic history.

Expedition 18 Flight Engineer Greg Chamitoff makes a move in the Earth vs. Space Chess match after his return to Earth.

Archival footage shows the Apollo astronauts viewpoint during their moon landing in 1971.

NASA's Fermi spacecraft orbits about 300 miles above Earth, scanning and imaging for gamma rays that scientists say hold answers to how the universe works.
