Today's question of the day
Yesterday's question asked: This night on CBS, a program that first aired 50 years ago will feature an animal that just got its own postage stamp in addition to its history-making TV show as its claim to fame. What/who is this animal? That would be Rudolph the Red-Nosed Reindeer who did indeed "go down in history," of course.
As for today's question, here it is: Recently a deep-space spacraft got a unique wakeup call from its interstellar hibernation to prepare for the closest encounter yet of Pluto, a dwarf planet. The spacecraft has traveled more than 3 billion miles during a nine-year flight to its historic visit of Pluto. How did the spacecraft wake up?
