"I am eager to know how NASA has successfully put the smartphones in to orbit? How was the smartphones behavior in the vacuum condition?"
Anandy, even I have the same question about communicate mode and channel, from Smartphone to the remote station in earth. If am not wrong, smartphones won't have such high capability RF signal handling capacity.
The point of the story is that common electronics can be used to effectively do what only government run projects have done in the past. Other concerns raised regarding radiation, performance in a vacuum are all very real issues to overcome, but the point is: common 21st century electronics – available to everyone – are sufficient to power devices we all previously thought required GOLIATH sized budgets.
Remember, making ONE of something is about as expensive as making one-million of something, when you consider economy of scale. Simple economics of mass production.
Good point, tekochip. It's not well known by many non-engineers, but games have always been at or near the state of the art in computational power. As you say, it's nice to know the technology is being put to a worthwhile use.
I had that thought as well. I think the way this becomes very inexpensive (in comparison to a previously typical satellite launch) is that you can launch a whole network of satellites with a single shuttle launche versus one, maybe two, satellites per launch. Whether that work that way or not, the cost of the satellite is a major part of the overall cost and a reduction in cost in "orders of magnitude" is some serious savings!
Add in the consumer advances in rocket launches (Elon Musk, etc.) and that part will also experience an economy of scale in the near future as well.
Phonesat is an inexpensive sat which takes the advantage of latest technology, but the smartphone's hardware is not built to take long-term radiation exposure and they will eventually start to breakdown.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
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.
