The Mars Phoenix Lander has now gone where two predecessors failed to go. The Mars Climate Orbiter spacecraft crashed into the Red Planet in 1999 because of a navigation error when “English” and metric units were confused. The Mars Polar Lander (MPL), was lost near the planet’s South Pole not long after that. As we reported here, the Mars. Phoenix Lander uses technology from the MPL, cutting its cost dramatically. The Phoenix landed Sunday night, with solar panels and a camera deploying just as planned. The first photos show a landscape that looks like a red paved parking lot.
We’re learning already. There is a close-up view of polygon-shaped formations (previously seen from space). Expansion and contraction of ice are believed to cause the shapes, something like the cracks that form in asphalt driveways over the winter. And that’s a great sign because it means the Lander may be close to ice crystals that may hold the clues to previous life. Next step: The specially developed shovel begins digging—chopping soil that can be tested in the on-board labs.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
