LOS ANGELES — SpaceX officials say they will be holding daily meetings with NASA and the Air Force in hopes of quickly determining what caused an unmanned rocket carrying cargo for the International Space Station to explode in midair just minutes after liftoff Sunday.

Teams of engineers have been deployed to review thousands of sources of data transmitted by the rocket before the explosion occurred, including video, company officials said.

SpaceX said that it is reviewing “every frame of video” and that its teams are putting together detailed timelines to determine exactly what happened.

Investigators still don’t know what caused SpaceX’s Falcon 9 rocket, which had flown successfully 18 previous times, to disintegrate and fall back to Earth, despite good weather and a smooth countdown.

As of Monday morning, founder Elon Musk tweeted, no cause had been determined after “several thousand engineering-hours” of review.
