This artist's conceptual image shows the Upper Atmosphere Research Satellite, or UARS. After two decades in orbit, the satellite will make an uncontrolled re-entry into the Earth's atmosphere.
Later this week, a retired NASA satellite the size of a school bus will finally fall back towards Earth after orbiting the planet for two decades. Most of it will burn up in the atmosphere. But about two dozen pieces are expected to hit the ground — somewhere.
And the biggest piece will weigh about 300 pounds.
If that's got you worried, NASA emphasizes that in the history of the space age, there have been no confirmed reports of falling space junk hurting anyone. But that doesn't mean no one has ever been hit.

Jack Rickard and Brian Noto have developed something of a cult following on their webcast EVTV, or Electric Vehicle Television, produced from their garage in Cape Girardeau, Mo.
Every week, they talk in soul-crushing detail about the intricacies of how to gut a gas-guzzling road warrior and convert it into an all-electric vehicle. On Wednesday, they host the Electric Vehicle Conversion Convention at the Cape Girardeau airport.
After years of appeals and controversy, Troy Anthony Davis is scheduled to be executed in Georgia on Wednesday. Georgia's board of pardons turned back Davis' appeal for clemency Tuesday, despite high-profile support for his claim that he did not kill a police officer in 1989.
Several witnesses have changed their testimony since Davis' trial; tens of thousands are protesting the execution. Former president Jimmy Carter, South African Bishop Desmond Tutu and more than 50 members of Congress are among those who have asked Georgia to commute Davis' death sentence.
Football season has hardly started and fans are already grousing about sideline reporters. To be sure, sideliners now exist in most all sports, and a handful of them –– notably Craig Sager of Turner, who was apparently in town the day the clown died, and thus got all his clothes –– are downright famous. While Sager is best known for basketball, it is football sideline reporters who are most identified with the sport.
A study should help men facing prostate cancer treatment get a better sense of how good their sexual function will be down the road.
Up to now doctors couldn't tell a man much about his chances of maintaining sexual function after surgery or radiation for prostate cancer.
"We'd say about half recovered or maintained their function," says Dr. Martin Sanda of Beth Israel Deaconess Medical Center in Boston. "And we'd be able to turn that up or down a little bit based on age."

How do you come up with a plan to help millions of people around the world avoid a chronic disease? For starters, don't treat the food companies that sell the products that contribute to those diseases as partners in the process. At least, that's what public health advocates argue — even as the accused companies say they're committed to making healthier products for the masses.
