Block 5 Falcon Heavy is targeting this fall for the next launch
SpaceX's next Falcon Heavy is planned to launch from LC-39a with a payload for the Air Force - this time with more power. The next Falcon Heavy launch will use all Block 5 boosters instead of the mixed Block 2/3 boosters like the one that launched in February.
The launch is targeted for no earlier than late October with a payload for the Air Force and its Space Technology Program-2 (STP-2) mission which includes dozens of spacecraft. NASA is also having a rideshare on this mission of their Deep Space Atomic Clock (DSAC), which is "the most precise atomic clock ever flown in space", states by the Jet Propulsion Laboratory.
SpaceX's new Block 5 Falcon 9 features an increased thrust of the rockets first stage as well as its second stage engines which allow for a higher payload capacity. The major improvement of these boosters are the capability of rapid reusability with the thermal coating on the important parts of the rocket and are expected to be flown up to 10 times before needing some minor refurbishment.
