SSI Racing's 2SSIC, the ZAP Alias electric car and Aptera's three-wheeler were
among the X Prize entrants on display at last month's Detroit Auto Show.

The night launch of a space shuttle is a wonderful sight. Sadly, it's a sight we may never see again. But the view gets even better when you're in space, and anyone with an Internet connection can take a virtual tour.

SpaceShipOne pilot Mike Melvill holds a sign reading "SpaceShipOne, Government
Zero" after the rocket plane's first spaceflight in June 2004. NASA's latest plans
have raised fresh questions about government-run vs. commercial space ventures.

First NASA laid out its new vision for human spaceflight, putting the moon on hold and focusing instead on new technologies and space commercialization. Then Congress weighed in. Now former astronauts, an aerospace guru and Hollywood's hottest director are boosting the debate to a higher level.

Pluto hasn't been getting much respect lately, but today the Hubble Space Telescope's team unveiled maps of the dwarf planet that are just a foretaste of the extreme close-up to come.
The maps spark fresh questions about the icy world that was discovered 80 years ago this month: Why has Pluto's northern hemisphere brightened so quickly over the course of just a few years? What's causing darker spots in the south? And why is Pluto getting redder all over?
"We think these changes are actually driven by seasonal changes," said Marc Buie, a planetary scientist at the Colorado-based Southwest Research Institute.
Huge amounts of methane and nitrogen ice appear to be moving from one part of the world to another through Pluto's wisp of an atmosphere. One particularly bright spot appears to be rich in frozen carbon monoxide.
So what's the precise mechanism for the shift? "That's a mystery," Buie said. The complete answers might well have to wait until 2015, when NASA's New Horizons probe swings past Pluto and its moons.

Black History Month is an occasion for looking back at the past achievements of African-Americans - including the discoveries made by George Washington Carver and Benjamin Banneker. But it's also an occasion for looking ahead to future achievements - and that's what TheGrio is doing this month with its list of "100 History Makers in the Making."
The list includes 10 scientists, engineers and environmentalists who are making an impact even now.
