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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
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.
