SpaceX’s recovery boat Mr Steven has a new net to catch Falcon 9 fairings

While photographer Pauline Acalin just barely missed a toasty Cargo Dragon returning to roost earlier that morning, a routine checkup on SpaceX’s Port of Los Angeles facilities revealed a hefty new net installed on the recovery boat Mr. Steven, as well as noteworthy activity at the huge tent currently harboring the rocket company’s BFR tooling.

After completing a thrillingly routine International Space Station resupply mission (SpaceX’s fourteenth) and spending a month on orbit, the commercial spacecraft reentered Earth’s atmosphere at a respectable 7.5 km/s before splashing down in the Pacific Ocean for the second time. Currently, SpaceX’s Dragon capsule is the only operational spacecraft capable of returning an appreciable amount of cargo from the ISS, and Capsule 110 (1 referring to Dragon 1, 10 referring to the tenth integrated spacecraft) returned even more cargo (nearly 2 mT) than it delivered to the ISS, including the space robot Robonaut 2, various completed experiments, and expired hardware. As of CRS-12, SpaceX has effectively ended production of new Cargo Dragon capsules, and has since flown two additional missions using refurbished capsules, perhaps paving the way for the first-ever triple reuse of an orbital commercial spacecraft. CRS-15, Dragon’s next flight, is currently scheduled for early July.

Although Pauline missed the battle-scarred capsule’s second return to Port of San Pedro, her travels were not for naught. Berthed at SpaceX’s leased dock space, SpaceX recovery technicians appeared to have installed and rigged a brand new net aboard fairing recovery vessel Mr. Steven in the several days between her visits. While he has yet to catch a fairing out of the sky (the ultimate goal of the program), the vessel has returned to land two of three largely intact fairing halves, the only payload fairings to have ever been recovered in one piece after an operational rocket launch. The first successful recovery followed PAZ, and although – per sources familiar with the matter – that particular half experienced catastrophic cracking while being hoisted from the ocean onto Mr. Steven’s deck, it appears that the second intact half (following Iridium-5) did not meet the same fate. It’s probable that – assuming Musk does mean to conduct helicopter drop tests – the structurally-intact Iridium-5 half is thus a prime candidate for air drop tests to perfect the system’s accuracy, as fairings immersed in saltwater are not candidates for operational reuse.

It’s good to first remember just how huge Falcon payload fairings are. (NASA, 2018)
