SpaceX is gearing up for its next Falcon 9 rocket launch tomorrow, which will send a telecommunications satellite into orbit for the company SES. It will also attempt to land its rocket after launch, but doesn’t expect a successful recovery.
The mission was supposed to take place in September, but was then repeatedly delayed after one of SpaceX’s rockets exploded on June 28th. Those delays prompted SpaceX to change the flight path for the launch to help get the satellite into its intended orbit much faster. That change will make it harder for the company to land the rocket post-launch.
