SpaceX is facing a new legal challenge as tribal and conservation organizations filed a lawsuit to block a federal land exchange tied to the Lower Rio Grande Valley National Wildlife Refuge in Texas.

The plaintiffs argue the deal would shift hundreds of acres of refuge property into SpaceX's hands and weaken protections for sensitive habitat and historic resources.

The Center for Biological Diversity reported the complaint targets the U.S.

Fish and Wildlife Service's approval of a swap that would transfer 715 acres from the refuge to SpaceX in return for 683 acres offered to the agency.

The groups say federal law requires refuge exchanges to deliver an overall conservation gain, not a net loss.
