The Day NASA's Fermi Dodged a 1.5-ton Bullet

On March 29, 2012, the science team for NASA's Fermi Gamma-ray Space Telescope learned that a defunct Cold-War spy satellite would pass too close for comfort on April 4. The two spacecraft were expected to occupy the same point in space within 30 milliseconds of each other, which meant that Fermi had to get out of the way. Credit: NASA's Goddard Space Flight Center
