Musk's post follows a Friday tweet from Chris Gebhardt, assistant managing editor and writer for NASASpaceFlight.com.

Gebhardt added to his initial tweet with a second saying that Feb. 6 is the earliest possible date for Falcon Heavy lift-off, subject to more slipping, especially if Musk's company pushes back the launch date of another of its rockets, a Falcon 9.
