The first manned spaceflight from US soil since the Space Shuttle program ended was scrubbed today due to weather. The next available launch window is this Saturday. Check out the launch on NASA Live: https://www.nasa.gov/nasalive
The last manned spaceflight from US soil launched on July 8th 2011 with Space Shuttle Atlantis mission STS-135. After retirement, Space Shuttle Atlantis was set up in its new home at the Kennedy Space Center.
This Falcon spacecraft also will not launch today due to excessive ice cream melting heat in Silicon Valley.
