Saturday's launch would have been "the most spacecraft ever deployed on a single mission," the company said, surpassing the previous 104-satellites launched in 2017 by India's Polar Satellite Launch Vehicle.

The latest SpaceX mission comes after Wednesday's successful launch of 60 Starlink satellites, a small portion of the 42,000 satellites SpaceX plans to launch to create a superfast global broadband service.

That launch was also delayed because of unfavorable weather conditions. SpaceX in January also delayed a launch for its Starship rocket prototype, after its first attempt exploded on the landing pad.

On Friday, SpaceX CEO Elon Musk said he was excited for the launch, which is part of a new ride-share program to provide small satellite operators affordable access to space.

"Launching many small satellites for a wide range of customers tomorrow," he wrote on Twitter. "Excited about offering low-cost access to orbit for small companies!"
