A SpaceX rocket exploded during a test fire prior to launch at Cape Canaveral, Florida, USA today. SpaceX officials said that "an anomaly" occurred while the rocket was being fueled.
The rocket was carrying an Israeli-made communications satellite, called Amos-6, for Facebook that was going to be sent into space to provide internet connection to some parts of sub-Saharan Africa.
SpaceX is an aerospace manufacturer and space transport services company headquartered in Hawthorne, California, United States that was founded by Paypal co-founder, and Tesla Motors CEO, Elon Musk.
