Capturing A Rocket Faring with a Net? Only SpaceX could come up with this Plan.

SpaceX's claw-boat ready to recover rocket fairing with a giant net

Teslarati's West coast photographer Pauline Acalin has captured some amazing photos of one of SpaceX's most immediately recognizable fairing recovery vessels berthed in the Port of San Pedro. For the first time ever, the vessel (officially named Mr. Steven) has had its iconic claw rigged with a massive net intended to gently capture Falcon 9 ...

From article, (SpaceX has been trying in earnest to recover its rockets’ fairings for approximately one year, but has yet to recover a fairing intact. While the company appeared to have recovered at least one large fragment on the East coast, success has proven elusive, and CEO Elon Musk noted in press conferences before and after Falcon Heavy’s inaugural launch that the task had proven more difficult than was anticipated. Despite the difficulties, SpaceX has no intention of surrendering their valuable fairings (a $5 million pallet of cash, as Musk once joked) to the sea.

 By all appearances, SpaceX has retained the same general strategy of fairing recovery mentioned in the past by Musk and other executives. To oversimplify, after launch, the payload fairing separates (mechanically) from the second stage once Falcon 9 or Heavy has left behind the majority of Earth’s atmosphere. After separation, each fairing half orients itself for a gentler reentry into the atmosphere with cold nitrogen gas thrusters, likely the exact same thrusters used in part to achieve Falcon 9’s accurate and reliable landings. Due to their massive surface area and comparatively tiny weight, fairing halves effectively become exceptionally finicky and awkward sails falling through the atmosphere at insane velocities, with the goal generally being to orient each half like a boat’s hull to provide some stability. Once they are low enough, assuming they’ve survived the journey from TEN TIMES THE SPEED OF SOUND and 62 MILES above Earth’s surface to a more reasonable ~Mach 0.5 and maybe 5 miles of altitude, the fun parts begin. At this point, each fairing half deploys a GPS-connected parachute system (a parasail, to be exact) capable of directing the massive hunks of carbon fiber and aluminum to a very specific point on the surface of the ocean.

Successful fairing recovery would quite literally entail an immediate cost reduction of as much as 10% of a Falcon 9’s entire advertised launch price, ~$6 million. For recovery of a single half, that figure is of course…halved, but $3 million is still an impressive instantaneous cost reduction. It’s unclear how SpaceX eventually intends to recover both halves of the fairing – a Mr. Steven sibling, perhaps? – but that is a problem for future SpaceX!)
