Canadian Prime Minister Brian Mulroney announced Canada's decision to proceed with Space Station participation when he visited with President Ronald Reagan. Canada agreed to perform preliminary design of a Mobile Servicing Center during Phase B of the Space Station definition and preliminary design study that would consist of a base structure with accommodations for payloads, orbital replacement units, utilities and thermal control. It would function as a multipurpose structure equipped with manipulator arms that would be used to help assemble and maintain the Space Station, as well as help keep instruments and experiments mounted on the Station's framework.

NASA officials concluded, and reported to the President's Commission, that the o-rings in Challenger's right solid-rocket motor were indeed the cause of the January 28 accident. They were still unable to cite a reason for failure of the seals, but hoped that tests over the next 10 days would give some clue. NASA also noted that the putty used to protect these seals might shed some light. (WSJ, Mar 24/86; CSM, Mar 24/86)
