On deck with Block 5 and Octograbber. I think this is the first time I have noticed how the hold on the booster is achieved. Once in port this angle is harder to get.

Who let the dog out? That guy. This is the garage that shields Octograbber from the landing blast on deck. @elonmusk can you help me out with a better name for this time saving robot?

13 штук? Первой конечно. Это не химфрезерование?

Видны следы фрезы. Вероятно, "зеркальное фрекзерование", по поводу внедрения которого на "Лавке" так негодовал Старый  А тут, поди ж ты, самая дешевая западная ракета - и "дорогая" мехобработка.

так что фрезеровали было давно известно. на НСФ фотка была несколько лет назад...

Я здесь! Где фрезеровка? Неужели фрезерованная вафля?

Если это следы фрезы то как же тогда выглядят следы пресса?

Все нормальные люди летающую технику делают из прессованных панелей и прессованных же силовых элементов. 
 Убедите меня что на снимке фрезеровка.

I made a quick check on the Merah booster before the storms rolled in today. The new cap was on and booster was off OCISLY. All four legs still attached before they had to go inside. #SpaceXFleet

Фрезерованная гладкая панель.

Из ракетной техники применение прессованных панелей приходит на ум только применительно к Р-36/Р-36М/Циклонам. Сходу и не вспомню, где еще применялись. А, вот, на Сатурн-5 на S-1C (не уверен, впрочем, возможно, там было банальное фрезерование - надо уточнить) и, емнип, на Титанах.

SpaceX's Falcon 9 Block 5 rocket looks no worse for wear after dual launches

By Eric Ralph
Posted on August 12, 2018

SpaceX's first Falcon 9 Block 5 booster has returned to Port Canaveral, FL once again after the rocket's second successful launch, likely the first of countless reuses to come over the next months and years. Of note, B1046.2 (Booster 1046, flight 2) was by all appearances in as good of condition as it was when it lifted off from Pad 40 just three days prior.

While it may be difficult to immediately distinguish between B1046's second launch and recovery and those of previous, older Falcon 9 boosters, Block 5 is a quite simply an entirely different story. Moreover, the fact that SpaceX went from the major upgrade's launch debut to first booster reflight in barely three months is an extraordinarily good indication that Block 5's first flightworthy design (especially the parts not visible to the public) is very close to its engineers' theoretical intentions.

Falcon 9 B1046's second recovery also happened to be the quickest yet for SpaceX by a healthy margin, taking just 4.5 days to travel 400 miles back to port, be lifted off drone ship Of Course I Still Love You, have its legs removed, and be loaded horizontally onto SpaceX's dedicated Cape Canaveral booster transporter. Whether or not the rocket itself is ready for another flight with absolutely zero refurbishing in between, this demonstration of just how quickly SpaceX's infrastructure can operate indicates that much of the framework needed for truly rapid reuse is already largely in place.

Once SpaceX is confident that Block 5 can be reflown with little more than new fuel added and has lined up multiple payloads for launch in just a few days or weeks, it's clear that the company will already have the ability to launch (and reuse rockets) so quickly that drone ship availability will become the primary bottleneck. For example, if B1046 could have shipped to one of SpaceX's launch sites moments after it was loaded on its transporter and prepped for the second launch within 24-48 hours of going horizontal, it's extremely unlikely that OCISLY could be readied for another booster recovery and towed several hundred miles off the coast in time to catch B1046 after its third launch.

As such, barring the extremely rapid completion of SpaceX's third drone ship (named A Shortfall of Gravitas), it can be all but guaranteed that SpaceX will need to use its land-based Landing Zone 1 to accomplish CEO Elon Musk's challenge of launching, landing, and relaunching the same Falcon 9 booster in less than 24 hours sometime before the end of 2019. Even then, it seems likely that SpaceX would either need to dramatically improve the turnaround capabilities of one of its launch sites or conduct those back-to-back launches using both of the company's two Florida pads (LC-39A and LC-40).

Regardless, the first reuse of a Falcon 9 Block 5 booster unequivocally marks the beginning of a new era for SpaceX and for orbital rocketry worldwide. According to one of SpaceX's webcast hosts during the second flight of B1046 (for the launch of Telkom 4/Merah Putih), the rocket's third launch (a first for SpaceX) is already in planning for an unspecified mission later this year. As SpaceX rockets begin to rack up 3, 5, 10, or more launches apiece and the act of reusing Falcon 9s becomes so routine that it bores all but the most ardent followers, you'll know that SpaceX has essentially succeeded in the first step of its master plan. Next stop: BFR and Mars.

SpaceX's Mr Steven spotted practicing Falcon 9 fairing catches with upgraded net

By Eric Ralph
Posted on August 14, 2018

SpaceX's fairing recovery vessel Mr Steven was spotted on Monday, August 13 conducting the first fairing recovery tests to involve actually craning a fairing half onto the huge, upgraded net, and doing so repeatedly in a short period of time. That practice will likely prove invaluable by allowing SpaceX to better understand the characteristics of Mr Steven's fairing-catching net, rigging winches, and general operational behavior.

Спойлер

As SpaceX gradually approaches their next Falcon 9 launch from Vandenberg Air Force Base, the company is also preparing for Mr Steven's next fairing recovery attempt, itself the second operational use of the vessel's massively upgraded arms and net. Known as SAOCOM-1A, the Argentinian space agency's Earth-imaging satellite is expected to launch no earlier than late September according to local South American media. Mr Steven's late-July upgraded net debut was largely foiled by unpredictable winds in the region the fairing was parasailing, with that uncertainty preventing the fairing from getting close enough to its targeted landing position for Mr Steven to catch it out of the air.

By all appearances, SpaceX is working hard to better understand how Mr Steven's huge new net behaves when interacting with a Falcon fairing half, a reasonable goal in order to ensure that the first successful fairing catch is not foiled by something as simple as the half sliding down the net and cracking on Mr Steven's deck. SpaceX's fairings are incredibly fragile and are liable to irreparable crack at the slightest hint of off-nominal forces, meaning that all recovery efforts need to be extremely gentle if SpaceX ever hopes to recover and reuse those fairings halves multiples times, if at all.

Still, even managing to reuse just one fairing half once for several launches (say, all California launches) would make a huge difference to the bottlenecked production line in SpaceX's Hawthorne rocket and spacecraft factory, which is working around the clock to ramp up production of the upgraded Fairing 2.0 while also winding down the old Fairing 1.0 manufacturing apparatus. Intriguingly, it appears that SpaceX's launch activity is likely to drop precipitously over the next several months, with no launches currently scheduled from the company's two Florida pads in September or October – apparently due to a lack of payload availability rather than anything SpaceX-related.

Vandenberg will thus be the focus of SpaceX's launch activities in September and October, hopefully supporting at least two missions. The first, SAOCOM-1A, is an Argentinian Earth observation satellite targeting a launch window in late September, reportedly delayed from September 5 to give SpaceX additional time to prepare Falcon 9. According to NASASpaceflight.com, SpaceX intends to refly Falcon 9 B1048 for this mission, giving the company just 6-8 weeks to refurbish the rocket and prepare it for the usual preflight static fire several days before launch. SAOCOM-1A will also likely mark the debut of SpaceX's West Coast rocket landing zone, known as LZ-2.
