How did safety regulations change after the space shuttle challenger explosion?

After the Space Shuttle Challenger explosion in 1986, safety regulations underwent significant changes to enhance oversight and accountability in NASA operations. The Rogers Commission, established to investigate the disaster, highlighted the need for improved communication and decision-making processes within NASA. As a result, NASA implemented stricter safety protocols, increased the role of safety officers, and emphasized the importance of data analysis and risk assessment in engineering decisions. These changes aimed to prevent similar tragedies and foster a culture of safety within the agency.
