When a multimillion-dollar extraterrestrial vehicle gets stuck in soft sand or gravel — as did the Mars rover Spirit in 2009 — Earth-based engineers take over like a virtual tow truck, issuing a series of commands that move its wheels or reverse its course in a delicate, time-consuming effort to free it and continue its exploratory mission.

Researchers Measure a Record-Setting Megaflash
It was a single lightning flash that streaked across the Great Plains for 515 miles, from eastern Texas nearly all the way to Kansas City, setting a new world record.
Weathering Change: Fewer Cold Fatalities, More Heat Emergencies in California
Temperature extremes affect rates of illness and death differently, leading to potential economic shifts from climate change.
Researchers Map Where Solar Energy Delivers the Biggest Climate Payoff
Using advanced computational modeling, a Rutgers professor, in collaboration with researchers from the Harvard T.H. Chan School of Public Health and Stony Brook University, reveal both the immediate and delayed climate benefits of solar power.
Deep Heat Beneath the United States Traced to Ancient Rift With Greenland
A large region of unusually hot rock deep beneath the Appalachian Mountains in the United States could be linked to Greenland and North America splitting apart 80 million years ago, according to new research led by the University of Southampton.
Huge Hidden Flood Bursts Through the Greenland Ice Sheet Surface
A huge flood triggered by the rapid draining of a lake beneath the Greenland ice sheet occurred with such force that it fractured the ice above and burst out across its surface.
