The largest nation on Earth is flying more people more places than ever before. Its struggle to do so without (further) destroying the environment could show the rest of the world a greener way to travel

When discussing any environmental issue in China, it's always a struggle to decide which deserves more emphasis: how dire the situation is, or how hard Chinese authorities are trying to cope with it. China's skies, waters and even sources of food are some of the most poisonously contaminated on Earth. Its efforts to curtail pollution and develop cleaner energy sources are some of the world's most ambitious.
How NASA and aircraft engineers intend to shape the future of air travel

NASA asked the world's top aircraft engineers to solve the hardest problem in commercial aviation: how to fly cleaner, quieter and using less fuel. The prototypes they imagined may set a new standard for the next two decades of flight.
The life-saving technology behind the daredevil's attempt to accomplish the longest free fall in history

Sometime before the end of this year, skydiver Felix Baumgartner intends to climb into a capsule suspended beneath a helium balloon, rise 23 miles above Roswell, New Mexico, open the capsule door, and jump out. On the 120,000-foot free fall—the longest ever attempted—he will face temperatures as low as –70°F and speeds of more than 700 miles an hour, becoming the first person to accelerate through the sound barrier without a craft.
Why drones won't be taking over our wars anytime soon

Early in 2008 on the Black Sea coast, a Georgian drone flying over the separatist enclave of Abkhazia transmitted an instantaneous artifact from the age of human flight—the video record of its own destruction by an attacking fighter jet. What happened that day was born of incendiary post-Soviet politics. The Kremlin backed Abkhazia and was furious that Georgia had bought surveillance drones to watch over the disputed ground. Georgia's young government flaunted its new fleet, bullhorning to diplomats and to journalists like me what the drones were documenting of Russia's buildup to war.
When NASA's new Mars rover lands on the Red Planet this summer, it's safe to assume it'll be some time in the morning or early afternoon at the Jet Propulsion Laboratory in California, home of the rover science and engineering teams. So that means it'll be mid-afternoon on the East Coast, evening in Europe, and so on —- pretty easy to figure out the time zones. But what time will it be on Mars? What time zone will Curiosity live in -- and how can you even tell?
Timekeeping on Mars is a bit like telling time on Earth, because the planets are similar in lots of ways. But there are just enough differences to drive a person slightly crazy.
