How did NASA's responses to the Challenger and Columbia accidents differ?

What will be an ideal response?

NASA learned a lot from its mistakes during the Challenger disaster. Its failure to immediately
communicate with key stakeholders brought it criticism in 1986. That mistake was not repeated at
the time of the Columbia accident in 2003. By doing a better job of handling public communications
immediately after the accident, NASA officials were allowed to conduct their own investigation of
the Columbia accident. That's a lot different from 17 years earlier, when a loss of credibility created
by poor communication caused the White House to turn the Challenger investigation over to an
independent board.
