President Barack Obama visited Cape Canaveral Friday, despite NASA postponing the launch of the space shuttle Endeavour.
Obama and his family had planned to watch the second-to-last space shuttle launch. Instead, the president was to tour an orbiter processing facility at NASA.
Mark Kelly, husband of wounded Arizona Rep. Gabrielle Giffords, is commander of the shuttle flight. Giffords was in Florida for the launch, but it was unclear whether Obama would still meet with her.
NASA said the next launch attempt would be Monday at the earliest.
From Cape Canaveral, Obama was to head to south Florida to deliver a commencement address at Miami Dade College.
