NASA's Redundancy is a Good Lesson for Terrestrial IT

Disasters and equipment failures can happen at any time, anywhere, and enterprise IT administrators need to properly prepare for them. This past week, NASA fixed an equipment failure aboard the International Space Station (ISS), and while it operates in a very different environment from data centers here on Earth, its operations can serve as a guide to terrestrial best practices.
NASA astronauts Rick Mastracchio and Mike Hopkins exited the ISS on Dec. 21 for a five-and-a-half-hour spacewalk to remove a faulty ammonia pump. On Dec. 24, the two astronauts took another spacewalk, this time installing a new ammonia pump to restore the ISS to full operations.
