You may check the broadcast of the launch on the stream:
The rocket launch is planned on the Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California which is located on the coast of the Pacific Ocean, 125 miles to the northwest from Los Angeles, exactly at 7:31 a.m. PST or 15:31 UTC.
The rocket has the B1049.2 Iridium-8 thrust, which was used on the launch of Telstar 18 VANTAGE satellite on the 10th of September, 2018.
The aim of the rocket is to lead 10 satellites with a total mass of 9,600 kg on a low polar orbit. The weight of each satellite is approximately 860 kg with 3.1 × 2.4 × 1.5 m dimensions.
The measures will be taken for the return of rocket stage on Earth. The landing is planned on the “Just Read The Instructions” drone ship which will be stationed in the Pacific Ocean.
Iridium NEXT satellites are communication satellites of the second generation of the Iridium Communications Inc. American company, which are equipped with voice communication and data transmission to mobile devices.
The Iridium NEXT working orbits are located at the altitude of 780 km under 86.4 ° degree decline with a roller ability in six orbital planes for about 100 minutes. The satellites which are already on the orbit will be removed with their combustion in the atmosphere.
In general, duration of the mission will last about 72 minutes. You can track down the timeline of the start here.
The Falcon 9 rocket has the following parameters:
- the height is about 70m.
- the diameter of a stage is 3,66m.
- the diameter of a nose cone ( cargo bay) is 5,3m.
The thrust will be provided by nine Merlin 1D engines and one 1D Vacuum engine, they all operate off a mixture of liquid oxygen and rocket kerosene. The rocket fully complies with NASA requirements.
