Self diagnosing software👩‍💻


In the future, machines everywhere will monitor their own health and request help when something’s wrong, according to the engineers at CEMSol LLC, a young technical services company that is developing such a system with NASA technology.


“There’s going to be an integrated system-health engine as part of every system out there, and it will be able to interface with other systems and components,” says David Cirulli, engineering vice president of the Phoenix-based company he cofounded. “That’s what’s missing today.”


CEMSol’s software is rooted in a system developed in 2003 by a computer engineer at NASA’s Ames Research Center to monitor an experimental hybrid rocket engine test bed that used both gas and solid fuel.


During a test launch of the Orion Crew Vehicle in December 2014, the Inductive Monitoring System (IMS) that CEMSol later licensed was used to monitor electrical systems on the space capsule.

Traditionally, this task would have been accomplished by building models and running simulations, but NASA’s David Iverson instead developed the Inductive Monitoring System (IMS) to gather and interpret real data automatically.



HUNDREDS OF SYSTEMS AT A GLANCE
It’s a pretty straightforward concept: IMS collects data from sensors that measure temperature, pressure, fuel flow, voltage, and other vital signs from within a system, then mines those results to establish a baseline for normal behavior. Any future data that don’t fit the baseline could indicate a problem or impending failure. And while human engineers or operators can understand the interactions between five to seven entities at most, Cirulli says, data-mining software such as IMS can see how hundreds of systems relate to each other at a glance.

Mini_pumps ? life on Mars☄️🌑

MINI-PUMPS The same miniaturized pumps on the Mars Curiosity rover are at work on Earth. Finding evidence of life on Mars requires high-tech equipment, whether that life is extinct or currently living below the surface and producing methane. Those same resources can be used on this planet during an industrial accident or dangerous chemical spill to let emergency crews know what they’re dealing with. But that’s only if the equipment can be used onsite. A mass spectrometer offers that kind of support on and off this planet. A mass spectrometer analyzes ionized samples of material by measuring the mass of the ionized molecules to determine the ratio of different isotopes in it or learn about the structure of its molecules. This information can be used to determine a sample’s age, how it formed or what molecules it contains (See Distant Encounters). But to land on Mars or be available for onsite emergency use on Earth, this equipment needs to be smaller and more rugged than the large mo...

Biological life raft☣️

🌍 Earth is a biological life raft thatsustains human life in the inhospitable environment of the cosmos. This planetary closed-loop system provides oxygen, water and essential nutrients while recycling waste, purifying contaminants and renewing resources. It does all of this using only the things that already exist in the biosphere. And NASA is learning just how this life raft functions in order to create a portable replica of the biological system we call home. A closed-loop system only uses the resources on hand. In other words, no resupply shipments make it necessary to reuse and recycle everything. On Earth, biology takes care of these processes naturally and efficiently, according to Jitendra Joshi, an engineer based at NASA Headquarters. Joshi studies the systems that sustain human life in space, such as microbiological systems for waste treatment for long duration space missions.   A closed-loop system only uses the resources on hand.   “The water we drank this morning...

About Portable power

PORTABLE POWER That 10% low power warning on your phone or the red battery on your tablet are helpful reminders to plug in. But they’re also a sign of trouble when you’re in the woods, all the outlets in the airport waiting area are taken, or you forgot your charger. Having a lightweight, affordable portable solar panel that makes it convenient to recharge all those batteries is now a viable alternative, thanks to NASA. “We’ve had a lot of small business partners looking not just at advanced cell technology, but also at maintaining low costs,” says Mike Piszczor, chief of the Photovoltaic and Electrochemical Systems Branch at NASA’s Glenn Research Center in Cleveland. “For space applications, a typical cell that’s about 1.5 by 3 inches is $400–$500, and that’s because they go through flight qualification in addition to the manufacturing process used. It saves in the long run, because even with that very expensive cell technology, it’s so efficient that it saves in overall system co...
