Block 5 is the upgraded model Musk says could be reflown about a hundred times. >The updated rocket also has a distinctive new look, with a black interstage section that sets it apart from earlier versions. It blasted off from Florida's Kennedy Space Center at 4:14 p.m. ET on Friday, carrying the Bangabandhu satellite-1, the first satellite for Bangladesh.
