SpaceX Rocket Launch Of SES-12 Set For June 4, 2018

CAPE CANAVERAL, Florida – The launch of a SpaceX Falcon 9 rocket carrying a SES-12 telecom satellite is scheduled to liftoff on Monday, June 4, 2018 from Space Launch Complex 40 at the Cape Canaveral Air Force Station in Florida.

The launch was moved from Friday to allow SpaceX to run additional tests on Falcon 9’s second stage.

The launch window opens at 12:24 a.m. EDT and closes at 5:21 a.m. EDT.

Weather 70% “GO”

The latest forecast from the U.S. Air Force 45th Weather Squadron gives a 70% chance of overall acceptable launch weather conditions. Liftoff winds are the primary weather concern on launch day.

Phaseout Block 4 Cores

The first stage of this Falcon 9 rocket is using one of the three remaining Block 4 cores that are being phased out for the improved Block 5 design.

This ‘flight proven’ Falcon 9 first stage was previously used to launch the U.S. Air Force’s secretive X-37B ‘mini-shuttle’ in 2017.

No Attempted Landing

SpaceX will not attempt to land this Falcon 9 first stage on land or sea.


The SES-12 satellite will provide direct-to-home broadcasting, VSAT, Mobility and High Throughput Satellite (HTS) data connectivity services in the Middle East and the Asia-Pacific region, including India and Indonesia.

SES-12 is capable of supporting requirements in multiple verticals from Cyprus in the West to Japan in the East, and from Russia in the North to Australia in the South.
