Want to get away? Thinking about a place with warm water and soft sand? Sounds nice. But think twice before you wade into that inviting surf. Chances are there are stingrays in the area.

... That's the message received from a bleary-eyed comet-chasing space probe on Monday, much to the relief of ground-based controllers who sent it a long distance wake-up call after nearly a three-year nap.

The European Space Agency received the communique from deep space on schedule at 1 p.m. ET from Rosetta, some 500 million miles away on a trajectory to rendezvous with comet 67P/Churyumov-Gerasimenko in August. It's been in sleep mode to conserve power.

"I don't know why you're on Mars, but whatever the reason for going to Mars is, I'm glad you're there and I wish I was with you."

That was a part of astrophysicist Carl Sagan's message, recorded a few months before he died in 1996, to the future human inhabitants of Mars.

Some of the earliest science fiction imagined voyages to the Red Planet. We now have the space-faring technology, and getting humans to Mars actually seems within reach. It would certainly involve massive resources and a lot of danger, but some believe the rewards would be massive.

From Ashes To Ashes To Diamonds: A Way To Treasure The Dead
