About Project Calliope

'Project Calliope' is a satellite being launched by a group of space & music enthusiasts on the "TubeSat" platform (http://tinyurl.com/skycall). It'll be an ionospheric detector transmitting sonifiable... Full Bio

I now own half a satellite... and in a way, you do to.  The Scientific Blogging "Project Calliope" satellite order has been placed!  Thanks to Hank's SB contribution, we have the 'science' half covered.  The other half of the satellite is up to the music community, and I'll let you know as soon as that's signed, sealed and delivered.

Half is crucial.  WIth half, we are 'go' for construction.  With our first half payment, we get:
  1. the actual hardware
  2. all the detailed tech specs
  3. a slot on the launch schedule

Being on the launch manifest is great from a project management standpoint-- it starts the clock ticking and lets us know what deadlines to aim for.  It also has promotional value, since we want to be the first musical satellite, and not get scooped by some university outfit that read about our idea and decided to emulate it.

The full tech specs will be nice, also.  We know what we need in a broad sense, but in tasks like the specific computer model and coding environment, in particular, details are important.

Most important is to get our hands on the actual satellite hardware.  There's a world of difference between writing up plans and schematics, and actually building something.  Sometimes the written spec isn't enough.  You also need to know what access you have to the inner workings.

You can imagine having a 6-foot closet but finding out there's only a 1-inch keyhole to get into it, for example.  Tiny clearances can make a world of difference, as anyone who has tried to move a too-big sofa through a doorway or replaced a screen door can attest.

Over at NASA's Goddard Space Flight Center, in the large assembly building, they have a full-sized mockup of a Space Shuttle cargo bay.  Word is, this was a request of a saavy engineer who realized they could build a satellite that, in theory, fit into the shuttle.  But they could reduce the risk and uncertainty greatly if they actually test-fitted it into a mock shuttle bay, just to make sure it worked in real life.

It's as the saying goes, "in theory, there's no difference between theory and practice, but in practice, there is."

Stay tuned,
Alex
