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.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
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.
