Teslarati photographer Pauline Acalin has captured SpaceX's first West Coast Falcon 9 Block 5 booster recovery in the best detail yet seen of the rocket upgrade, well-worn after its first successful launch of Iridium NEXT-7, July 25.

Iridium-7 marked a number of important debuts for SpaceX: Falcon 9 Block 5 (Booster 1048, in this case) completed its first West Coast launch from SpaceX's Vandenberg pad, drone ship Just Read The Instructions' (JRTI) first rocket recovery attempt and success in nearly ten months, and recovery vessel Mr Steven's first (albeit unsuccessful) attempt at catching a Falcon fairing with a dramatically enlarged net and arms.

Although inclement wind conditions foiled Mr Steven's fairing catch effort and put pressure on Falcon 9 B1048's journey to JRTI, Iridium-7 was flawlessly placed in orbit and Falcon 9 managed a slightly off-center but still thoroughly successful landing on the drone ship off the coast of California. With that launch and land debut on the West Coast and a second successful East Coast launch of a Block 5 rocket to the East just a few days prior, SpaceX has effectively demonstrated the basic functionality and reliability of the upgrade's many far-reaching changes to the underlying Falcon 9 architecture.

JUST READ THE INSTRUCTIONS RECOVERS A ROCKET

After nearly ten months largely spent berthed at SpaceX's original Port of San Pedro dock space, drone ship JRTI has at long last returned to sea and successfully recovered a Falcon 9 booster, this time marking the West Coast launch and landing debut of the Block 5 rocket. Photos of the drone ship and rocket's return to port were some of the best ever seen, thanks largely to the port's layout and narrow mouth, which allowed Teslarati photographer Pauline Acalin to put giant telephoto lenses and a unique top-down perspective to good use.

Iridium NEXT-7 thankfully brought an end to the understandable but still-painful practice of intentionally expending twice-flown Falcon 9 boosters in the ocean after launch. Thanks to Iridium-7's new Block 5 booster, B1048, expending the rocket was out of the question, as it likely will be for most Block 5 launches in the future. A combination of several expendable missions and an unfortunate duo of recovery anomalies (a small fire after Koreasat 5A and the Falcon Heavy center core landing failure) led to JRTI sitting on the sidelines since October 2017, as a considerable subset of its critical thruster hardware had to be stripped in order to keep East Coast sister ship Of Course I Still Love You (OCISLY) operational for a handful of attempts in 2018.

Many of the months JRTI spent at berth were thus without the pod thrusters the drone ship needs to keep itself at the proper landing point once at sea. Still, JRTI departed the port with a full complement of four blue thrusters on the evening of July 22 and had a highly successful return-to-action. Sadly, it's unclear how much SpaceX will need the vessel within just a month or two from today – after the final Iridium launch (NEXT- 8 ) in November or December, perhaps all of SpaceX's future Vandenberg launches will be lofting lightweight payloads that should allow the company to rely almost entirely on its brand-new rocket landing zone – conveniently colocated barely 1000 feet from the pad – for CA rocket recoveries.

Falcon 9 Block 5 booster (B1048 ) arrived at Port of Los Angeles on July 27 after landing at sea aboard drone ship JRTI. Photos captured by Pauline arguably show the best details yet seen of the rocket upgrade, ranging from titanium grid fins to extraordinary shots of its sooty-but-still-sorta-shiny Merlin 1D engines.

Myriad others provide an amazing sense of place with SpaceX technicians conducting thorough post-landing checkouts, carefully documenting the booster's condition, and generally wrenching on a massive, orbital-class rocket that completed a suborbital jaunt to space just days prior.

Of particular note are detailed views of the silky black "highly flame-resistant felt" now covering Falcon 9's interstage (the top segment), landing legs, octaweb section, and raceways (the black lines traveling up and down the rocket). Compared to beat-up, older Falcon 9s, B1048's shielded components look barely worse for wear, and it would genuinely be difficult to determine if the rocket had flown before without the telltale soot fingerprint present after every Falcon 9 recovery.

The only mystery that still remains is what exactly Falcon 9 Block 5's octaweb heat-shielding looks like, reportedly one of the most critical and research-intensive upgrades necessary for true rapid reusability and reliability through many, many flights. Now built largely of titanium bolted to the octaweb, among a number of other extremely heat-tolerant metals and materials and even active water-cooling in spots, the new heat-shield was designed to carry the brunt of the reentry heating Falcon 9 experiences with ease.

SpaceX tests Falcon 9 Block 5's landing leg retraction and preps for first reuse

By Eric Ralph
Posted on July 30, 2018

In the two months since SpaceX first debuted its Falcon 9 Block 5 rocket upgrade with a successful May 2018 launch and landing, the company has forged ahead with final Block 4 or older launch and two additional launches and recoveries of brand new Block 5 boosters, growing the fleet of flight-proven and thus flight-worthy rocket boosters to three.

Спойлер

Given the dramatic changes implemented in Block 5 and the pathfinder nature of these new boosters, SpaceX has spent much of the following time conducting tests and extensive analyses to verify new designs and new technology, ranging fr om teardowns to tests of specific components like landing legs on a recently-recovered East Coast booster.

https://www.youtube.com/watch?time_continue=4&v=0b59dzTjrTQ

Most prominently on that to-do list was a deep-dive teardown of inaugural Block 5 booster B1046, which was apparently completed within the last week or so – as evidenced by the sooty booster's appearance at SpaceX's Cape Canaveral Launch Complex 40 (LC-40) around July 24th. The purpose of that teardown was to give most of Falcon 9's many thousands of individual and critical components a thorough examination, particularly those parts most impacted and worn by launch, reentry, and landing. That most likely includes B1046's black octaweb and interstage thermal protection, its nine upgraded Merlin 1D engines, the "dance floor" heatshield at the rocket's base, and landing legs, among myriad other smaller aspects.

More recently (July 27 and 28 ), SpaceX technicians attempted and completed the first retraction of a Block 5 booster landing leg (B1047 in Port Canaveral, Florida), compared with the current practice of removing both the landing legs and booms before rotating the recovered rocket horizontal and transporting it to a nearby refurbishment facility. Briefly discussed by CEO Elon Musk, Block 5 includes a number of landing leg optimizations, intended to improve robustness, increase reliability, and significantly ease reuse.

"So essentially deploying the landing gear and stowing the landing gear is now a very easy thing to do [on Block 5 boosters], whereas previously it required several hours to re-stow the landing gear. Which can now be done with an actuator, pretty easily."

Given the fact that it took a full day to prepare for the retraction of the first leg and that the task appears to be accomplished with a fairly complex and manual lifting mechanism requiring several workers to function, it's possible that the retraction and leg hardware described by Musk is still undergoing some form of testing or production optimization before being added to flight hardware. Nevertheless, photographer and journalist Ken Kremer observed the retraction sequence from start to finish (movement-wise) and pegged it at around 40 minutes total to go from fully deployed to fully stowed.

In all fairness, truly rapid and near-automatic leg retraction would only be of value to SpaceX once the company needs to refly Falcon 9 with less than a week or two between launches, at which point spending a day or two carefully removing or stowing landing legs outweighs the cost of adding highly specific hardware useless during flight (and thus stealing mass that could otherwise be fuel for a gentler booster recovery or a higher payload orbit).

Keeping as much of that leg retraction hardware on the ground as possible thus makes a lot of sense in today's launch industry, wh ere SpaceX simply has no material need for near-automatic, internally-actuated leg retraction on Falcon 9 (only necessary for extremely rapid turnaround). Still, if the company hopes to achieve Musk's 24-hour booster turnaround challenge by the end of 2019, SpaceX technicians and engineers will need to have a solution in place to retract Falcon 9's landing legs as quickly as practically possible – every minute will count for such a rapid reuse.

Теплостойкая пленка как временный вариант уже была в зоне решеток. Для метанового варианта Фалькона нужен хотя бы прототип Раптора с земной тягой 100 тс, который Маск должен предъявить ВВС в 2018 году.

SpaceX's newest Falcon 9 booster arrives in FL as rocket fleet activity rapidly grows

By Eric Ralph
Posted on August 1, 2018

SpaceX's fifth Falcon 9 Block 5 first stage was spotted a few dozen miles away fr om arriving at Cape Canaveral at the same time as a freshly launched and landed Block 5 booster was being transported from its drone ship at Port Canaveral to Kennedy Space Center.

The now flight-proven booster in question – B1047 – completed a successful launch of the massive 7100 kg Telstar 19V satellite on July 22nd (EDT), after which it landed safely aboard East Coast drone ship Of Course I Still Love You. Three days after that, sooty Falcon 9 B1047 arrived at Port Canaveral, wh ere it took five days to prepare for transport to one of SpaceX's several Floridan refurbishment facilities. That transport was captured by an impressive number of independent observers from start to finish, in this case winding up at Pad 39A's hangar (or horizontal integration facility, HIF) for examination and refurbishment before its next launch.

Finally, Redditor /u/Kent767 caught the sooty booster's arrival at Pad 39A. (Reddit – Kent767)

Simultaneously, multiple separate members of the subreddit /r/SpaceX observed a different Falcon 9 rocket booster being transported in Western Florida and later Orlando, this time a brand new core shrink-wrapped in the usual black plastic – fresh from static fire testing in McGregor, Texas. A photographer flying in the area in mid-July caught the most likely booster candidate (B1050) vertical on the Texas static fire test stand, rounding out a dizzying array of photos documenting SpaceX's rigorous test and transport system in action over the last several months.

B1050 will likely be tasked with lifting communications satellite Es'hail-2 in very late August or early September. Intriguingly, the appearance of B1050 in Florida also happens to indicate that SpaceX's next West Coast launch – SAOCOM 1A, NET September 5th – will have to launch aboard a flight-proven Block 5 booster, of which B1047 and B1048 will be up for consideration. B1051, the next new Block 5 booster expected to ship from Hawthorne to Texas to launch pad, is specifically reserved for SpaceX's first Crew Dragon mission (DM-1), an uncrewed demo flight that could launch in October or November.

Two weeks after it was spotted on the McGregor static fire stand, B1050 rolled into Orlando, FL on July 31st, headed East to Cape Canaveral. (Reddit – alexbrock57)

It's likely that B1051's testing and static fire in McGregor will take much longer than the average booster acceptance testing, meaning that the facility's Falcon 9 booster test capabilities will likely be saturated for a month or longer, pushing B1052's commercial launch readiness into late September or early October. In reality, B1048 is the only practical option for an early or mid-September launch in California, and that tentative and unofficial booster reflight would crush the current rocket turnaround record by more than four weeks (42 days vs. 72 days).

Booster B1048 just completed its successful debut with the launch of Iridium NEXT-7 and has been under the watchful care of SpaceX recovery technicians since its July 27th return to Port of San Pedro aboard autonomous spaceport drone ship Just Read The Instructions (JRTI). Of particular note, SpaceX technicians took the extraordinary step of opening up B1048's Merlin engine service bay panels (one per engine along the circumference of the rocket's base) for several hours on July 30th.

As far as Falcon recoveries go, SpaceX has never been documented performing a similar procedure while the booster is still dockside – perhaps it's related to the fact that B1050's East Coast arrival means B1048 will have to be ready for its second launch faster than any SpaceX rocket before it.
