1.   Eventually the team hopes to replace the motors with actuators made of shape memory alloys, which use small temperature changes to induce motion.

2.   She was, of course, charged again when the window motor was replaced, and the mechanic beat the flat rate on that job, too.

3.   Astronauts Linda Godwin and Daniel Tani had trained to replace the motors, but NASA decided the problem could be fixed simply with the thermal covers.

4.   Godwin and Tani had trained to replace the motors, but NASA decided the problem could be fixed simply with the thermal covers.

5.   Godwin and Tani spent weeks if not months training to replace the motors, which had been exhibiting increased currents and even stalled on occasion.
