According to Saudi Arabia-based satellite operator Riyadh in SpaceNews, Arabsat 6A compliance is planned to be launched in December 2018 or January 2019. Thus, the SpaceX's first Falcon Heavy satellites will be launched back at the beginning of the year for the launch.
This planned date of launch is of course of special importance for SpaceX. This departure, which will be carried out by US Air Force's STP-2 technology on behalf of Arabsat 6A, is already aroused. According to a statement made by a spokesman related to the subject Air Force Space Command, it was stated that STP-2 would normally continue to be investigated because it was intended to be released this month, but the SpaceX and Air Force did not complete the adequacy tests.There is no information on when the next Falcon Heavy mission will take place after STP-2 and Arabsat 6A. So these throws are going to give very important clues about how well a kind of satellites are doing. There has not yet been a launch for Intelsat, Viasat and Inmarsat, among the operator candidates for SpaceX's Falcon Heavy project. It is known that in the case of Arabsat 6A compliance, these companies are waiting in line.
The fact that Falcon Heavy launchers want to be actively based dates back to a much more distant past. Because Falcon Heavy titles were considered for Viasat's ViaSat-2 and Inmarsat satellites, but it was the reason for the earlier launch of the Arianespace Ariane 5 rocket last June.
Inmarsat spokesman Jonathan Sinnatt said the London-based satellite operator is still an option for Falcon Heavy's launch. Intelsat, the oldest Falcon Heavy customer in SpaceX, has a history dating back to the company until 2012, but there is no information on exactly what they are carrying. "We still have the Falcon Heavy deal but have not yet launched a satellite launch," said Jason Bates, another Intelsat spokesman. California-based Viasat does not yet have a working calendar associated with the SpaceX rocket, and it's unclear when they will launch a launch.
With Viasat-2 launch contracts for Falcon Heavy launch, Viasat continues to negotiate with SpaceX and other companies for future work. As you may recall, in February, a Falcon Heavy rocket and a red Tesla Roadster were sent to the ground and caused a worldwide resonance.
