Balloons outfitted with innovative steering devices and robot probes could be the future of planetary exploration. Dr. Alexey Pankine, a fellow at the NASA Institute for Advanced Concepts (NIAC), presented an analysis of balloon applications for planetary science at the World Space Congress in Houston, Texas last month. His study, entitled Directed Aerial Robot Explorers or DARE, is funded by NIAC.
At the center of the DARE concept are balloons that can float in planetary atmospheres for man
JASON II reaches most of the world ocean floor and sends data ashore via the Internet
A new generation of remotely operated vehicle (ROV) capable of routine operation to depths of 6,500 meters (21,320 feet) and communicating its data back to shore via the Internet has been developed by the Woods Hole Oceanographic Institution (WHOI). The vehicle, JASON II, recently completed its first science cruise off the coast of Washington and Oregon and is currently at sea in the Pacific wo
Microchips may be small, but their impact on our world has been huge. And this impact goes beyond the obvious effects of e-mail, cell phones and electronic organizers: A new study shows that the “environmental weight” of microchips far exceeds their small size.
Scientists have estimated that producing a single two-gram chip — the tiny wafer used for memory in personal computers — requires at least 3.7 pounds of fossil fuel and chemical inputs. The findings were reported Oct. 25 on the Web si
Researchers from the University of Michigan and RIKEN, a research institute in Japan, say the biological motors that nature uses for intracellular transport and other biological functions inspired them to create a whole new class of micro-devices for controlling magnetic flux quanta in superconductors that could lead to the development of a new generation of medical diagnostic tools.
As integrated circuits become smaller and smaller, it becomes increasingly difficult to create the many “gu
NASA scientists using satellite data have shown that shifts in rainfall patterns from one of the strongest El Niño events of the century in 1997 to a La Niña event in 2000 significantly changed vegetation patterns over Africa.
Assaf Anyamba and Compton Tucker of NASA’s Goddard Space Flight Center, Greenbelt Md., and Robert Mahoney of Global Science and Technology Inc (GST) analyzed satellite derived images of vegetation from 1997 to 2000. They noticed regions of above normal “greenness” ov
A large study comparing trucks fueled by natural gas with others fueled by diesel found the natural gas vehicles produced only a quarter of the carbon monoxide emissions and half the oxides of nitrogen emissions of their diesel counterparts.
The study was conducted using package trucks operated by United Parcel Service (UPS), which has the nation’s largest private compressed natural gas (CNG) fleet. The study compared the operations, maintenance, performance, and emissions characteristics
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
