A bad week for space exploration

Apollo 1: fire kills 3 astronauts on launch pad. January 27, 1967 Shuttle Challenger: Explosion kills 7 astronauts during launch. January 28, 1986 Shuttle Columbia: Break up on re-entry (apparently) kills 7 astronauts. Feb. 1, 2003
You think maybe there should be a moratorium on space activities for the week including Jan. 27th to Feb. 1st?
Note: I checked and Apollo 13 took place in April 1970. But then they survived.
