it's the tribe's land
Not quite the same. While no astrologer has ever held title to a comet, an astrologer surely *could* file suit if NASA tried to build a facility on the astrologer's own land.
Kitt Peak is located on the tribe's land -- it's withing the Tohono O'odham reservation. I'm sure there's a treaty in place that grants the tribe considerable say in the management of that land, even if such treaties were largely ignored until the last 30 years.
