New concerns being heard about the future of parts of NASA Glenn.
An audit says five testing and research facilities at NASA Glenn and its Plum Brook Space station in Sandusky don't get enough use and could be expendable.
The list includes a big wind tunnel, two vacuum chambers and two rocket firing stands that played big roles in past missions into space.
The agency's mission keeps changing. And budget cuts could hit duplicate or underused operations. Both Ohio Senators disagree with the audit.
