The name refers to the red and while colors of Indonesia's flag.
In the tiny hours of Tuesday morning, SpaceX launched an Indonesian satellite in its 15th flight this year.
Falcon 9 B1046.2 lifts off from Pad 40 for its second launch.
The Block 5 is SpaceX's final version of the Falcon 9, and features improvements to enable first-stage reuse 10 or more times.
Liftoff, from pad 40 at the Cape Canaveral Air Force Station.
Riding 1.7 million pounds of thrust from nine Merlin main engines, the Falcon 9 rocket soared into the stratosphere, then its first stage detached around two-and-a-half minutes after liftoff.
Seconds before touchdown, four legs deployed and the rocket settled to an on-target landing.
Falcon 9 B1046.2 successfully landed aboard OCISLY after its second launch, paving the way for its third mission and beyond. It will now attempt to land on the Of Course I Still Love You barge - if successful, the company will most likely be planning for its third launch. A second engine firing was carried out 26 minutes after launch to finish the job.
First and foremost, this is by no means meant to demean the awe-inspiring reality of what SpaceX has managed over the last several years, which includes the first successful Falcon 9 landing, the first commercial orbital-class rocket reuse (also Falcon 9), and the first commercial reuse of an orbital spacecraft (Cargo Dragon), and many others. It was also the 28th time SpaceX has recovered one of its first stage boosters intact, and the 15th re-flight of a Falcon first stage. After it is hauled back to Cape Canaveral, it will be inspected and, if no major problems are found, it will go into the stockpile of available block 5 stages ready for use in downstream missions.
It was only the fourth flight of an upgraded block 5 booster since the rocket's debut in May and the first launch and recovery of a previously flown block 5 - the same stage that helped launch a Bangladeshi satellite during its maiden flight three months ago. "Ironically, we need to take it apart to confirm that it does not need to be taken apart. So this rocket probably won't re-fly for a couple of months". Block 5 is different, and that's by design.
Not so for SpaceX, which Monday relaunched and retrieved its block 5 Falcon 9 rocket for the first time.
The turnaround between the Bangabandhu 1 and Merah Putih missions did not set a record for the shortest time between flights of the same Falcon 9 first stage.
For Telkom Indonesia, the launch restores the state-owned operator's fleet back to three satellites after one of its satellites exploded in orbit last August.
Block 4-generation Falcon 9 boosters could only be reused once. The new satellite will replace Telkom 1, which failed in a mysterious debris-shedding event in geostationary orbit previous year.
Merah Putih's on-board engine will circularize its orbit over the equator in the coming weeks.
Launch coverage can be seen on Space Coast Daily TV. The satellite will provide Internet, telephone and cellular backhaul services, according to SSL. The new satellite will service Indonesia and Southeast Asia.
