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.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
