SpaceX's massive Starship spacecraft exploded in space on Thursday minutes after lifting off from Texas, causing the FAA to halt air traffic in parts of Florida, in the second straight failure this year for Elon Musk's Mars rocket program.

Several videos on social media showed fiery debris streaking through the dusk skies near south Florida and the Bahamas after Starship broke up in space shortly after it began to spin uncontrollably with its engines cut off, a SpaceX live stream of the mission showed.

The failure of the eighth Starship test comes just over a month after the seventh also ended in an explosion. The back-to-back mishaps occurred in early mission phases that SpaceX has easily surpassed previously, a setback for a program Musk has sought to speed up this year.
