NASA Balloons Study Effects of Volcanic Eruption

A team of NASA and University of Wyoming scientists has ventured into the Australian bush to send a series of balloons aloft. The balloons will make measurements of a volcanic plume originating from neighboring Indonesia.The campaign, in Australia’s Northern Territory, is part of an effort to better understand the climate effects of volcanic eruptions.The KlAsh (Kelud Ash) experiment is based in Darwin, Australia, where smaller balloon payloads are being launched over the Indian Ocean. Larger balloons, with payloads that must be recovered, are being launched from Corroboree, a remote area about 60 miles south of Darwin.The larger balloon, filled with helium, measures about 115 by 65 feet when fully inflated.Almost all of the energy entering Earth’s climate system comes from the sun. Some of that energy is absorbed by the planet, while the rest is radiated back into space. Ash and sulfate reflect and absorb energy differently, and may also have different chemical impacts on the stratosphere.“Understanding those characteristics is important for climate models that include periodic volcanic activity,” said Terry Deshler, principal investigator for the University of Wyoming’s instrumentation.SourceAlso: Learn about Targeting and Monitoring of Volcanic Activity.

Would You Be Satisfied with a "Smart Home?"

Technology companies, including Google and Apple, are investing in "smart home" technologies that connect household devices — lighting, security systems, garage-door openers, climate controllers or kitchen appliances — with mobile devices. Research indicates that the global "smart home" industry will grow. Some have concerns, however, that the technology could be hacked, lead to a clutter of multiple apps, and make the smartphone a single point of failure.

Metal Injection Molding Turns the Volume Up, and Down

When increased quantities of metal parts are needed, metal injection molding (MIM) is often a logical next step. Our free MIM white paper covers the multi-step process involved in molding metal parts, detailed technical specs needed for design, commonly used materials and a comparison to other metal-forming technologies like direct metal laser sintering and die casting.

Liquid Silicone Rubber Takes the Heat

Our comprehensive white paper on liquid silicone rubber provides a detailed look at the injection-molding process and offers guidelines to achieve better molded LSR parts. While there are some shared similarities to thermoplastic injection molding, LSR is a thermoset material with a unique set of design characteristics.

Industry Roundtable: 3D Printing

It’s being called a revolutionary change in the way we design and make products – a disruptive technology that will have far-reaching effects for both engineers and consumers. It’s 3D printing, and it is shaping the future of manufacturing. NASA Tech Briefs spoke recently with executives at four of the leading 3D printer vendors about what 3D printing is today, what it will be tomorrow, and if it really will change the world.
