CAPE CANAVERAL - NASA next week will try to free a knob stuck between the dashboard and a cockpit window on shuttle Atlantis - a problem that some fear could trigger lengthy launch delays or even an early retirement for the orbiter.

But NASA shuttle program officials effectively are saying, "Not so fast."

"I think it's too early to know whether it's a big deal or not," said Kyle Herring, a spokesman for NASA's Johnson Space Center in Houston.

A notched rotary knob from a lighting bracket somehow got wedged between the orbiter's cockpit instrument panel and one of six forward windows during NASA's fifth and final Hubble Space Telescope mission in May. The knob is designed to mount a work light to a bracket.

Somehow, it floated into a recess in the corner of the cockpit, and two edges of one of its crescent-shaped notches are pressing against the inside of the triple-pane window, which is a little more than 2 1/2 inches thick.
