Announcing Sacred Mounds, a novel of Magical Realism and Historical Fantasy from Jim Metzner, with a foreword by Hutke Fields, principal chief of the Natchez Nation.
Cyclonic hordes of insects, a telepathic despot, body-swapping sex - just a few of the surprises Salvador Samuels encounters when he is swept back to pre-colonial times, walking in the moccasins of a blind Indian - who, in turn, has been transported into Salvador's body in present-day America. Sacred Mounds Book Cover Four hundred years apart, they are bound by a mission to rescue our world, aided by the mysterious presence of the mounds. Thousands of these ancient earthworks once dotted the landscape of North America. We still don't know why they were created. Sacred Mounds suggests they are as important today as when they were made over a thousand years ago. Sacred Mounds weaves the stories of two men, each a stranger in a strange land. With the help of two remarkable women, they must find a way to save our planet and return home.

Kids' Science Challenge: Sports on Mars - Spirit Stuck
At NASA's Jet Propulsion Laboratory, engineers are testing a rover in a simulated sand pit, in hopes of freeing Spirita rover that's been stuck in a real sand pit on Mars.

Spirit Stuck


SL: "So, right now she's just really quiet, sitting on the surface all by herself, cold, trying to stay alive (laughs), waiting for the seasons to change."

JM: The 'she' in question is NASA's Mars rover named Spiritit's a robotic science station on wheels that's sent back some amazing photographs from the surface of Mars. But for over a year now, Spirit has been stuck in the sand on Mars. I'm Jim Metzner, and this is the Pulse of the Planet. Stephenie Lievense is an outreach coordinator at NASA's Jet Propulsion Laboratory, and she's giving Kids' Science Challenge winner Tyrone Hutchinson a tour of a JPL laboratory, where they've got a model of Spirit stuck in a sand pit exactly like the one on Mars, and they're trying to find ways to get the vehicle out.

SL: "So far they haven't been able to figure out how to get her out. And now they've stopped trying. Do you know why?"
TJ: "Why?"
SL: "There are seasons on Mars, just like on Earth, and right now it's starting to be winter on Mars, and when it's wintertime on Mars"
TJ: "So, it freezes, so she'd never be able to get out."
SL: "Absolutely. You got it. It gets so cold that the rover has to use any bit of power that she has just to stay alive. Do you know how Spirit gets her power?"
TJ: "Solar?"
SL: "Solar, absolutely. So she sucks up as much solar power as she can get, and uses that to charge herself up and keep herself nice and warm. But unfortunately in the wintertime, there's not that much sun. So she's kind of stuck. She has to just sit there and wait until it's summer again."

JM: At the Jet Propulsion Laboratory, engineers continue to run tests in their sand pit, so that when the warmer weather hits the Red Planet, they'll have better luck of freeing the real Spirit.
