NASA Goes Bargain Basement With New Satellite
coondoggie writes to tell us that NASA has announced a new low-cost satellite that could be ideal for those who wish to get into space quickly and (relatively) inexpensively. "The Fast, Affordable, Science and Technology SATellite (FASTSAT) is 39.5 inches in diameter — not much larger than an exercise ball. It is hexagonally shaped and clocks in at a little less than 200 Lbs. It can carry a payload up to 110 Lbs. [...] NASA said FASTSAT is just the right size for earth observing missions, space science missions, and technology demonstrations. 'We think we can do whole missions for less than $10 million instead of the traditional $100s of millions, and that includes the launch vehicle, the satellite, and the widget you want to test,' said Marshall Space Flight Center's Edward 'Sandy' Montgomery in a release."
It'll be interesting to see if this drives a trend towards smaller, COTS parts for these satellites. Personally, I'm excited about this. This could be the first step towards an all-in-one probe (a la Star Trek) like device.
'Loose' is when your pants are three sizes too big. 'Lose' is when you misuse 'loose'.
When I was a kid, I did not know that playing with estes model rockets was actually making me a rocket scientist!!
On the lighter side, this is just one more step toward open source styled science. I'm glad to see it. It will slowly break the stranglehold that big military business has on such ventures, and hopefully spread the wealth around a little bit better.

Data costs tend to be almost as much as the actual hardware since there are only a few locations that are prime for beaming data down - and they're in Alaska or the far North.
Surrey Satellites/University of Surrey in the UK have been making micro sats for decades. (customers include Department of Defence, Banking consortia, ESA, etc etc)
Their second satellite UoSat-2 was build in less 11 months, and they're more than happy to take commercial orders for satellites costing way less than 4 million dollars and still they can make a profit on it, launch included!
Heck this micro satellite isn't even small by today's standards! Give it a couple of years and we'll see satellites that are the size of a large coffee cup. How do I know? My colleagues are building them!
Noting that accurate pointing of on-board sensors is vital for most Earth and astronautical observations, I'd be interested to read about the precision and accuracy of the attitude control system. The A-train satellites are each the size of a Ford van and have multiple spinning wheels, torquers, star trackers and gyros to sense the spacecraft attitude and maintain the correct orientation. Using only mag rods, nulling any residual attitude errors will take quite a while and I'm not sure you'd ever have a 'stable' platform.
Out of curiousity, what do you think is a "sky high" salary and why do you think someone in NASA is being paid that much?
PBS's Wired Science magazine had a great segment (warning: video)on all of the things that someone has to do to launch a satellite - their example was a telecommunications satellite. It's a good watch if you want to know exactly why $10 million is not exactly a bad price....
