He also had not ruled out the potential that something hit the rocket, causing the chain that led to the explosion.
In a photo taken by an Orlando Sentinel photographer, the mangled support structure for the rocket can be seen alongside towers that also burned and charred.
In a series of posts on the social media site Twitter early Friday, the billionaire gave more information on the investigation into the incident.
In particular, Musk was focused on a “quieter bang sound” that he heard a few seconds before the explosion.
“May come from rocket or something else,” he said on Twitter.
Some Twitter users asked Musk whether sabotage could have been to blame or whether something could have hit the rocket. He said he had not ruled out that something hit the rocket.
Musk has more than 5 million followers there and often shares news and information about SpaceX and his electric car company Tesla there.
The explosion, he said, happened during what he characterized as a “routine filling operation.”
He also said he appreciated support and advice from NASA, the U.S. Air Force and the Federal Aviation Administration.
SpaceX’ Falcon 9 rocket had been planted at Cape Canaveral, awaiting a Sept. 3 launch of a satellite that was to help in Facebook’s quest to expand Internet service in Africa.
But the explosion at about 9:07 a.m. destroyed the satellite, along with the rocket and mangled the support structure on the launch pad.
