"NASA launched a novel project in April, putting into orbit three satellites that employ an off-the-shelf commercial smartphone as the control system"

Dylan, amazing. Smartphone as the control system!! Am curious to know about the communication between these Smartphones and remote tracking centre.

Every time a new game system comes out we read the specifications out loud and compare the computational power to the original Super Computer.  "All this to play games"?  At least the off the shelf consumer electronics in this example will be doing something worthwhile.

I agree, it's quite amazing to see NASA using COTS products in such an expensive and complex piece of machinery...especially for the crucial control aspect of the satellite. But I have done some coverage of NASA and know they are trying to do more with less, so necessity could be the mother of invention here. It also shows what great minds can do when they don't want to reinvent the wheel.

Wow!!! commercial smartphones into the orbit. I am eager to know how NASA has successfully put the smartphones in to orbit? How was the smartphones behavior in the vacuum condition?

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.

Launching cost

Inexpensive, usuage of commercial smartphones seems like a great idea, but still the launching cost  will be expensive. How will this factor effect the Phonesat future?

Wonder if they left the "Find my phone" app on it?   :)

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.

I hate to see the "roaming" fees charged by the phone's network provider.  ;)

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.

No, we're not having delusions of grandeur -- this is the weapon of a Jedi Knight. And we're dying to see how it works. Today, we tear down a lightsaber.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us itís probably the airbag that saved our lives or the life of a loved one. Perhaps itís the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
Fully adopting multiphysics simulation software enables companies to optimize cable and systems designs for a wide range of harsh environments.
