Southern California Wildfires Burn Out Of Control: New Nasa Satellite Images Show Fires’ Rapid Growth

October 23, 2007
NASA satellites continue to capture remarkable new images of the wildfires raging in Southern California. At least 14 massive fires are reported to have scorched about 425 square miles from north of Los Angeles to southeast of San Diego.The latest images, captured by NASA satellites on the afternoon of October 22, show the thick, billowing smoke coming off the numerous large fires and spreading over the Pacific Ocean.

The Chinese Chang’e 1 lunar orbiting mission is scheduled to launch on 24 October.

Chang’e 1 is planned to be the first of a series of Chinese missions to the Moon. The spacecraft is scheduled to launch on 24 October 2007 at 10:05 UT (18:05 Chinese Standard Time) on a CZ-3A (Long March 3A) booster from Xichang Satellite Launch Center. Chang’e will orbit the Moon for a year to test the technology for future missions and to study the lunar environment and surface regolith. The primary engineering objectives of the mission are to validate the technology necessary to fly lunar missions. The primary science objectives are to obtain three-dimensional stereo images of the lunar surface, determine the distribution of some useful elements on the surface and estimate their abundance, survey the thickness of lunar soil and to evaluate helium-3 resources, and to explore the environment between the Moon and Earth.Chang’e 1 at the Xichang Satellite Launch Center.

NASA Offers $2 Million Lunar Lander Competition Prize

October 24, 2007
The purpose of the lunar lander challenge is to accelerate technology development leading to a commercial vehicle that could one day be capable of ferrying cargo or humans back and forth between lunar orbit and the moon’s surface.

Giant balloon to loft world’s largest solar telescope

October 2007
A balloon designed to loft the world’s largest solar ultraviolet telescope high into the atmosphere has performed a successful 10-hour test flight. When the telescope makes its first science flight in 2009, it will boast vision more than two times sharper than any previous solar observatory, shedding light on what causes potentially dangerous outbursts from the Sun.Slender hoses, blown into arcs by the wind, partially filled the Sunrise project’s balloon with helium before launch on 3 October. Much of the balloon – which is larger than a jumbo jet – is left unfilled so it can expand as it rises into the stratosphere, where air pressure is lower.

Planet’s CO2 Production Surges

22 October 2007
An international team of scientists has taken another look at how rapidly Earth’s atmosphere is absorbing carbon dioxide (CO2)–the biggest greenhouse gas in terms of volume–and the news is not good: A high-flying world economy is pumping out the gas at an unprecedented rate. Current CO2 production is outstripping the best estimates used by modelers to predict future climate trends.

Reason for flu the Season

19 October 2007
With flu season almost upon us, it’s a good time to ponder why influenza strikes us hardest in the winter months. A new study chalks it up to the fact that the virus appears to be more infectious at colder temperatures and lower humidity. The findings could lead to strategies that help curtail transmission of the disease.

Evolutionary Sprint Made Us Human

23 October 2007
Many more genes separate humans from chimpanzees than scientists believed. A new study shows that what sets us apart from our closest primate cousin is the accelerated rate at which we acquire new genes and ditch unnecessary ones.

New CU-Boulder Study Confirms First-Known Belt Of Moonlets In Saturn Rings

Oct. 24, 2007
A team led by the University of Colorado at Boulder has detected an unseen belt of moonlets in Saturn’s outermost “A” ring (top image, outer purple band). The moonlets in the belt were detected by gravity “wakes” 10 miles to 20 miles across (boxed in bottom image) by the narrow-angle camera aboard the NASA Cassini spacecraft.
