SpaceX have opted to slip their next two missions, to allow for corrective work on the upper stage engine. The company’s Falcon 9 v1.1 is now set to launch with the SES-8 spacecraft no sooner than November 12, with the Thaicom-6 satellite set to follow just one month later. Both launches will take place from Cape Canaveral’s SLC-40 launch complex.
The debut launch of the upgraded Falcon 9 successfully deployed Canada’s Cassiope spacecraft into orbit on September 29.
However, after safely deploying its payloads, the upper stage was then set to restart its Merlin VacD engine for a second burn related to SpaceX’s ambitions to create a fully reusable launch system. An anomaly with the restart held no mission impact, but the company’s CEO and chief designer, Elon Musk, did note they expected to implement corrective actions ahead of the next launch.
