The original launch date wasn't July 4th btw. It was the previous saturday. While the Space Shuttle is iconic, it is a decade past its intended sunset date. Despite the recent disaster, space travel has been a remarkably safe venture considering the number of SUCCESSFUL flights and especially considering the complex nature of its design. The SSME is still the most efficient liquid rocket despite it's nearly 30 year age. All that being said, the space shuttle was conceived as a lower cost alternative to the disposable craft of Mercury, Gemini, and Apollo. Unfortunately, costs exponentially rose. Another fun fact? The problems that have recently come to light regarding the foam breaking off have always been there. Since day one. Since the disastrous flight of Columbia, the media and other sources have simply focused on it, just as they did on the SRB's after Challenger. The SRB's aren't even really what failed, despite how dangerous they are. Once lit - you're done, you have to ride it out. You can't shut them off. The new lift vehicle is going back to a capsule (Apollo derivative) and putting the whole thing in a multi stage design on top of an SRB. After each launch the SRB's are dredged out of the ocean and entirely remanufactured out west - then shipped via railroad all the way to Floride where they are barged into another location and finally assembled in the VAB.
Something else about the shuttle - it doesn't fly. The landing? Controlled crash, the shuttle generates no more lift than a brick - literally. The wings serve only to slow it down. If they miss on their descent, there's no second chance. Their fuel was all in that pretty orange thing that burned up in the atmosphere on the way up. To simulate landing, they fly in a plane with the engines in full reverse. Not sure where I'm going with all this, just some less than commonly known things about the space shuttle

As for aborting space travel for a while, I think we've laid off enough from it already. How does anyone propose to deal with the fact that we're reproducing more rapidly than our planet can support? Colonization FTW.
