A private spaceship owned by a company called SpaceX is scheduled to blast off from Cape Canaveral in Florida early Saturday morning.
If all goes well, the unmanned capsule will rocket up on a mission to deliver food and other supplies to the International Space Station, becoming the first commercial spacecraft to visit the outpost.
The highly anticipated mission could mark the beginning of what some say could be a new era in spaceflight, with private companies operating taxi services that could start taking people to orbit in just a few years.
Back when the dinosaurs ruled the Earth, some hardy bacteria took up residence at the bottom of the Pacific Ocean. Eighty six million years later, they're still there. And a new study says they're living out the most Spartan lifestyle known on this planet.
Yes, there are more and more people on the planet, and yes, there are fewer and fewer fish in the sea, but do we really notice? After all, fish live in water and we live on land; so we don't mingle that much. If fish were sparrows, we might see a dramatic decline, but who misses what they don't see in the first place?
Archaeologists working in one of the most impenetrable rain forests in Guatemala have stumbled on a remarkable discovery: a room full of wall paintings and numerical calculations.
The buried room apparently was a workshop used by scribes or astronomers working for a Mayan king. The paintings depict the king and members of his court. The numbers mark important periods in the Mayan calendar.
