Shuttle Discovery Back in Hangar

Space Shuttle Discovery is getting a new new external fuel tank (No, that's not a typo.) The new fuel tank had some foam application modifications, but the new new external fuel tank is equiped with a heater to prevent ice and temperature and vibration sensors to measure tank performance.
It remains to be seen whether Discovery will fly again as planned, but NASA is doing its very best, for the astronauts first and then for the program. As it should be.
