Falcon 9 comparisons


Quite a difference between the Falcon 9's of JCSAT & Thaisat. The Thaisat booster has divots in the legs where the crush zones are. They might not be divots but bulges because the crush zones would have expanded. The JCSAT booster has panels removed from the engine compartment. The panels are still in places for the Thaisat booster, but out of alignment. It's like some engines got shoved up into the fuel tank by the force of ground effect & combustion instability.

From far away, it's a marvel of alien technology, far beyond normal human experience. Up close, it's a dirty, beat up, soot covered machine with the hood panels of a Model T. Unlike a car, there's nothing but metal in the engine compartments. Hard to imagine a car being made of nothing but metal. Any other material would burn up. The panels allow good access to some of the outer engines, but fixing problems with the center engine is a bitch.

It would have made sense to use carbon fiber landing legs, but the divots reveal they're pure metal. Anything else would burn up from the heat of the engines. An enormous amount of metal mass in landing legs & grid fins was invested in recovery. Some payloads are going to require going without the landing legs & grid fins.

Now some enhanced videos. USLaunchreport is the only 1 providing any significant coverage of the booster recovery.
