Mars Space Rovers:
Originally built for a planned 90-day mission, Spirit and its robotic twin Opportunity have now spent more than five years exploring their respective Martian landing sites on opposite sides of the planet.
Both Spirit and Opportunity have suffered some aches and pains associated with their unexpected longevity on the surface of Mars. Most recently, Spirit experienced an odd bout of amnesia when it failed to record and report a day of activities to flight controllers on Earth last month."

While in North Korea..:
"North Korea has said it has the right to "space development" — a term it has used in the past to disguise a missile test as a satellite launch. When it test-fired a shorter-range Taepodong 1 missile over Japan in 1998, it claimed to have put a satellite into orbit. "
