No one said it would be easy to conduct scientific experiments robotically on Mars. And in fact the Phoenix Mars Lander continues to run into nagging problems. What’s very interesting is how engineers working with scientists on Earth are developing workarounds to solve the problems. It’s engineering at its best, and it reminds me a little of the steps taken on the ill-fated Apollo 13, although the Mars mission is not life-or-death.
In the latest problem, soil dumped on a screen is clumping, and not passing through to analysis equipment, even after vibration. Engineers decided to employ a motorized rasp on the scoop that was actually designed to dig out granite-like ice below the polar surface. Tests show that the scoop, when tilted, does drop fine particles of soil while it is being vibrated by the rasp. Previously, the scoop was just dumped outside down, dumping the soil.
Look for tests in a few days that will chemically analyze the soil.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
