A SpaceX rocket launch lights up the sky above San Diego.
A new launch window was later announced for 10:32 a.m. Monday, closing at 11 a.m. Working toward a backup launch opportunity on December 3'.
The rocket was originally scheduled to be launched on November 19 but it was delayed to conduct further inspections.
The launch, part of the company's Spaceflight SSO-A: SmallSatExpress mission, is planned to launch a reusable Falcon 9 booster to carry satellites into space. Bad weather caused subsequent delays.
Fans can watch the Falcon 9 rocket take-off live on SpaceX's webcast.
This will be the second largest rideshare mission ever and the largest for a single mission on U.S. soil. Among them there are 15 microsatellites (22-220 pounds) and 49 cubesats - small artificial satellites of the Earth for space exploration, including 25 small satellites beloningg to worldwide organizations from 17 countries, including the United States, Australia, Italy, the Netherlands, Finland, South Korea, Spain, Switzerland, the United Kingdom, Germany, Jordan, Kazakhstan, Thailand, Poland, Canada, Brazil and India. That will make it the largest single collection of spacecraft to launch from the US.
Despite some hiccups, the third Falcon 9 trip is a major milestone for SpaceX.
Some of the satellites are aiming to build an internet network that could support smart devices.
The satellite networks could aid companies tracking agricultural shipments, for example, which are moved without internet access.
This is the third time the launch has been postponed.
Almost all of the satellites on SpaceX's payload aim to prove that a combination of smaller, simpler and cheaper satellites can perform the same complex functions as much larger, more expensive satellites.
