Will astronauts reach Mars by 2030?

This week's Question: Last week, NASA's 30,000-pound Orion capsule landed in the Pacific Ocean after going further than any spacecraft built for humans had reached in more than 40 years. Without astronauts aboard, Orion circled Earth for two orbits, eventually reaching an altitude of 3,600 miles so it could achieve a high re-entry speed, one similar to a beyond-Earth-orbit flight. The mission is a step toward eventually bringing astronauts to deep space. NASA says astronauts could reach Mars sometime in the 2030s. What do you think? Will astronauts reach Mars by 2030?

Researchers Fabricate Rewritable Paper

Chemists at the University of California, Riverside have fabricated novel rewritable paper, one that is based on the color-switching property of commercial chemicals called redox dyes.  The dye forms the imaging layer of the paper. Printing is achieved by using ultraviolet light to photobleach the dye, except the portions that constitute the text on the paper. The new rewritable paper can be erased and written on more than 20 times, with no significant loss in contrast or resolution.“This rewritable paper does not require additional inks for printing, making it both economically and environmentally viable,” said Yadong Yin, a professor of chemistry, whose lab led the research. “It represents an attractive alternative to regular paper in meeting the increasing global needs for sustainability and environmental conservation.”SourceAlso: Learn about Biodegradable MEMS Based on Cellulose Paper.

Air Traffic Lab Answers Questions About Future Flying

The holiday season is upon us and that means crowded airports and delayed flights. Researchers at NASA's Langley Research Center are working to change that. They are conducting studies to help reshape the future of American air travel in a brand-new Air Traffic Operations Laboratory (ATOL). They are studying the Next Generation Air Transportation System, a new national airspace technology being implemented by the Federal Aviation Administration.

Wireless Devices Used by Pilots are Vulnerable to Hacking

A new class of apps and wireless devices used by private pilots are vulnerable to a wide range of security attacks, which in some scenarios could lead to catastrophic outcomes, according to computer scientists at the University of California, San Diego and Johns Hopkins University. They examined three combinations of devices and apps most commonly used by private pilots to access the same information available to the pilot of a private jet at a fraction of the cost. All have to be paired with tablet computers to display information.

Foldable Material Can Support Many Times its Weight

Researchers at Drexel University and Dalian University of Technology in China have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration, and radio frequency shielding in technology from portable electronics to coaxial cables.
