If the great thing about this satellite is the sheer number of stars that it can measure, I wonder if a network of amateur spectographers could contribute too?
Keeping in mind I know next to nothing about spectroscopy and expect to be schooled in exactly why this is not possible in about 5 minutes time :-)
But the idea of knowing which stars came from the same stellar nursery is exciting nonetheless. :-)
