Pictured here is the launch of CRS-8. The first stage of CRS-8 will be Space X’s first relaunched booster for the SES-10 mission. Also note that CRS-8 was the first stage to successfully land on the autonomous drone ship, marking the first landing on a floating platform for anyone. SES-10’s first stage will attempt another landing at sea.
