For those of you who requiring an extra bit of encouragement this week, we invite you to watch the Curiosity rover land on Mars.
Its nine month, 352 million mile journey from our planet to the next culminated in an unpredictable seven minute landing sequence that turned out to be more thrilling than just about any fiction we can remember.
Curiosity is a manmade mobile science lab designed to travel to Mars, land without smashing into a trillion pieces, keep a keen robotic eye out for signs of past or present life, and then report back it's findings.
Watch the animated simulation of its landing cut with reaction shots of scientists and engineers watching the live drama unfold (above).
These men and women spent the better part of their careers constructing a marvelous piece of machinery but, on this day, they could do nothing but hope and pray.
We won't trivialize this momentous achievement with John Carter jokes or an ill-suited hyperbole. The video speaks for itself.
On some days, it's just inspiring to be part of the human race.
