Satellite data has been used to show that Earth's plants now absorb 606 million tonnes less carbon than they did ten years ago, according to a new study. The study, published in the journal Science, used data from a NASA satellite that orbits Earth every 15 days to build up a global map of changing […]

China has its Eye on the Sky
China has announced it will launch its first high resolution, stereoscopic mapping satellite for civilian use in the second half of 2011. The announcement came within two months of the country’s successful launch of a navigation satellite, its fourth orbiter. The mapping satellite is expected to "provide steady and reliable data sources for surveying […]

Predicting Sandstorms with Satellite Data
A new method for predicting dust and sandstorms using infrared satellite images has been developed by researchers at the University of Pittsburgh in the US. The scientists have been able to determine when destructive sandstorms are likely to occur. They used their methods to accurately forecast a large 2008 dust storm in New Mexico, two […]
Space Junk to get Tracked by Laser
An Australian company has developed a laser tracking system that will help stop chunks of space debris colliding with spacecraft and satellites in the Earth's orbit. The laser tracking system has previously been used to track satellites, but Electric Optic Systems said it could now locate and track debris as small as 10 centimetres […]
GPS Used to Predict Tsunamis
A team from NASA’s Jet Propulsion Laboratory in California has successfully demonstrated a new tsunami prediction system. The system, which uses real-time data from the agency’s Global Differential GPS network, successfully predicted the size of a tsunami following an 8.8 magnitude Chilean earthquake in February. The prediction system combines global and regional real-time data […]
Crowdsourcing on the Moon
NASA's Lunar Reconnaissance Orbiter has been sending detailed images of the moon from its 50km orbit to scientists since June 2009. The images provide remarkably detailed views of the lunar surface, including features as small as 50cm. Over the course of its mission, LRO is expected to generate 70-100 terabytes of data – […]
New Technique Distinguishes Smoke From Clouds
A group of US scientists has discovered a way to distinguish polluting smoke from clouds. They have developed a multi-spectral approach using remote sensing measurements from NASA’s Moderate Resolution Imaging Spectro-radiometer. The scientists are based at George Mason University and NASA Goddard Space Flight Centre. The researchers have identified smoke by filtering out other […]
