Going, Going, Gone!

The Friday File: After travelling for 36 years and 12 billion miles, NASA just confirmed that on August 25, 2012 (yes 2012), Voyager 1 became the first human-made object to depart the solar system. It’s so far from earth it takes 17 hours travelling at the speed of light to send/receive signals from Voyager. To date, the total cost of the mission is $1 billion or about 8.3 cents/mile. Thrifty!
