ЦитироватьSpaceX nails second Falcon 9 landing in 48 hours, fairing catch foiled by weather

By Eric Ralph
Posted on July 25, 2018

Just a handful of days after SpaceX's second-ever successful launch and landing of their upgraded Falcon 9 Block 5, the company has completed the same feat on the opposite side of the United States, debuting the Block 5 rocket with a launch and booster recovery from California's Vandenberg Air Force Base (VAFB).
Спойлер
The booster in question, Falcon 9 B1048, is the third Block 5 booster to roll off of SpaceX's Hawthorne, CA assembly line and is now the first Block 5 rocket to launch from the company's California launch facilities. On the opposite coast, SpaceX's second Block 5 Falcon 9 booster (B1047) completed its own successful launch and landing, lofting the heaviest commercial satellite to ever reach orbit (Telstar 19V).


While weather during camera setup was absolutely spectacular, the predawn launch window meant that no sun was available to force the ever-present VAFB fog back over the ocean. (Pauline Acalin)

SEVEN MONTHS, FOURTEEN LAUNCHES

Today's near-flawless predawn mission saw Falcon 9 place 10 Iridium NEXT satellites in a polar Earth orbit, during which the rocket's Block 5 booster completed the first landing on Just Read The Instructions in nearly ten months and Mr Steven made his first attempt at catching a parasailing Falcon fairing with his massive net and arms upgrades. Those upgrades, tracked tirelessly by Teslarati photographer Pauline Acalin for the better part of July, took barely a month to go from a clean slate (old arms and net fully uninstalled) to operational, fairing-catching status, an ode to the incredible pace at which SpaceX moves.

Sadly, the vessel's Iridium-7 fairing catch attempt was sullied from the start by inclement weather – primarily wind shear – that significantly hampered the accuracy of each fairing halve's parafoil guidance, meaning that Mr Steven's crew did see the parasailing halves touch down, but too far away to catch them in Mr Steven's large net. Falcon 9 B1048 had its own difficulties thanks to what engineer and webcast host John Insprucker described as "the worst weather [SpaceX] has ever had" for a Falcon booster landing. Nevertheless, Falcon 9 appeared to stick an off-center but plenty accurate landing aboard drone ship JRTI, although SpaceX technicians are likely going to wish they had the same robotic stage securer located aboard OCISLY on the opposite coast.

And more unbelievable plume interaction... (SpaceX)


And finally, a successful Block 5 booster landing on the West Coast! (SpaceX)

Just Read The Instructions, on the other hand, was similarly tracked but primarily to verify that nothing was happening – the vessel's last operational trip to the Pacific Ocean dates back to the first half of October 2017. Since then, SpaceX began a process of intentionally expending Falcon 9 boosters that had already flown once before, choosing to essentially start from scratch with a fresh fleet of highly reliable and reusable Falcon 9 Block 5 boosters rather than recover older versions of the rocket and attempt to refurbish them beyond the scope of their designed lifespans.

The Block 5 design, however, has taken the countless lessons-learned from flying and reflying previous versions of Falcon 9 and rolled them all into one (relatively) final iteration of the ever-changing rocket. With any luck and at least a little more iteration, Falcon 9 Block 5 boosters should be capable of launching anywhere from 10 to 100 times, 10 times with minimal or no refurbishment and 100 times with more regular maintenance, much like high-performance jet aircraft do today.

With three successful launches of new Block 5 boosters now under the new version's belt, it's safe to say that the rocket is off to an extremely good start. The most important milestones to watch for over the next several weeks and months will be the first reflight of a recovered Block 5 rocket, the first reuse of a Falcon 9 payload fairing, and then the first third/fourth/fifth/etc. reuse of Block 5 booster. On the horizon, of course, is SpaceX CEO Elon Musk's challenge to launch a Falcon 9 Block 5 booster two times in less than 24 hours, and do so before the end of 2019.

ЦитироватьSpaceX readies its California landing pad for September rocket recovery debut

By Eric Ralph
Posted on July 26, 2018

Just as SpaceX successfully debuted Falcon 9 Block 5 at their California launch pad and returned drone ship Just Read The Instructions (JRTI) to rocket recovery duty after a nine-month leave, the company's next West Coast mission is already aligning for an early-September launch.

The mission, SAOCOM-1A, will feature yet another inaugural event – the first use of a West Coast landing pad less than a mile fr om SpaceX's Vandenberg launch pad.
Спойлер
For the last two and a half years, SpaceX's Florida launch sites (Pad 40 and Pad 39A) have also been privy to a unique secondary facility known as Landing Zone-1, located a few miles away from both pads inside the boundaries of Cape Canaveral Air Force Station (CCAFS). In fact, although a number of attempts were made to recover a Falcon 9 booster aboard drone ship Of Course I Still Love You (OCISLY) in 2015, the first successful Falcon 9 booster landing happened to occur at LZ-1, followed four months later by the first successful recovery by sea.

WHY LAND ON LAND, WHY LAND AT SEA?
Спойлер
The primary draw of an equivalent land-based pad is both simple and massive: while SpaceX's autonomous drone ship vessels are complex, comparatively easy to damage, and extremely expensive to both operate and maintain, a concrete circle on land has relatively tiny fixed and variable costs, does not have to concern itself with volatile ocean conditions, and does not require a fleet of tugboats and service vessels to operate. Rough estimates place the cost of taking a drone ship, tugboat, and crew transport vessel hundreds of miles off the coast on missions that can last 7-14 days anywhere from $500,000 to $2 million or more, depending on how you tabulate costs. Either way, the drone ship fleet will always be more complex and more expensive than simple concrete pads on land.

One problem with land-based landing zones is that returning rockets to their launch sites is very fuel-intensive, requiring propellant margins at booster stage separation that dramatically reduce the payload that can be placed into low Earth orbit (LEO), let alone higher-energy missions to geostationary orbit. As such, without massive performance improvements, drone ships like JRTI and OCISLY will be irreplaceable for as long as Falcon 9 and Heavy are flying – SpaceX simply cannot recover rockets during the geostationary launches that comprise a huge portion of their manifest unless they have those vessels.


 

If OCISLY is indeed tasked with catching another extra toasty Falcon later this week, fingers crossed that the vessel (and rocket!) make it through unscathed. (Elon Musk)

This brings us to another conundrum. SpaceX's Florida launch facilities support heavy commercial geostationary satellite launches as much as or more than any other type of payload in a given year of launches, meaning that the company's now-doubled landing pad at LZ-1 is only used every once and awhile for Cargo Dragon launches and other miscellaneous and rare launches that leave enough margin in Falcon 9. SpaceX's Vandenberg pad, on the other hand, is effectively bound to launching satellites into polar orbits (orbiting over Earth's poles versus around the equator) – safety regulations prevent large rockets from launching over populated areas like the entire continental U.S., as an example for California launches.

Equatorial launches from East to West are much less efficient than their opposite, as Earth's own rotation (West to East) provides rockets an appreciable performance boost. The point is that SpaceX's Vandenberg launches are for fairly particular payloads, usually LEO communications satellites and imaging satellites that thrive in polar orbits, wh ere one or a handful of satellites can observe almost anywhere on Earth over the course of a normal 24-hour. Those satellites also happen to be lightweight more often than not, meaning that many of the booster recoveries on drone ship JRTI could instead return to launch site (RTLS) for a dramatically simpler and cheaper recovery.

ENTER BLOCK 5
Спойлер
A West Coast LZ is even more intriguing and important with respect to the recent debut of Falcon 9 Block 5 at Vandenberg and the fact that all future launches. Even compared to SpaceX's Florida LZ-1, the company's Western pad is incredibly close to the launch pad. By landing less than a mile from SpaceX's VAFB integration and refurbishment facilities (and launch pad), recovery and refurbishment operations should be more effortless than any before it.

While the company's VAFB launch pad is a bit older than its Eastern cousins and requires at least 3-5 weeks between launches for repairs and refurbishment, that relaxed schedule may be unbeatable for proving out the Block 5 upgrade's true rapid reusability, as well as its ability to far more than two orbital missions per booster lifespan. SAOCOM-1A, one of two Argentinian Earth observations scheduled for launch with SpaceX, will begin that new era for SpaceX's Vandenberg operations, including a landing pad debut permit officially granted by the FCC in the last few weeks. The Falcon 9 booster that launches that mission is bound to have a storied future ahead of itself.

Current work looks like preperation for the removal of the legs. All hold down ires have been tightened, and all work appearsto be placed on the joints of the hydraulic mounts for the legs.

ЦитироватьSpaceX's first Falcon 9 Block 5 reuse will also be its quickest drone ship turnaround

By Eric Ralph
Posted on July 27, 2018

According to observations of SpaceX booster movements at Cape Canaveral Air Force Station on July 24, it appears that the company will reuse a Falcon 9 Block 5 booster for the first time ever on August 4, just over a week from today.

Independent of the booster flying, SpaceX will also break their internal record for drone ship recovery turnaround if they manage to launch and land another rocket on the 4th, just 14 days after Of Course I Still Love You's July 21 (EDT) booster recovery.

The Telkom 4 (Merah Putih) communications satellite will be sent by SpaceX to a geostationary transfer orbit and will become the second heaviest satellite ever launched by the company while still recovering the Falcon 9 booster, weighing in at around 5800 kg. While SpaceX's launch and landing for the record-breaking 7080 kg Telstar 19V mission may appear more impressive at face value, it's likely that Telkom 4 will be even more taxing for the rocket, thanks to the much higher geostationary transfer orbit the satellite will most likely be placed in.

BLOCK 5 BOOSTER TO BE REUSED FOR A THIRD LAUNCH IN TWO WEEKS

This will be SpaceX's third Falcon 9 Block 5 launch in less than two weeks if the schedule holds. More important than the schedule, perhaps, is the fact that it would appear that SpaceX intends to reuse the first Block 5 booster (B1046) for this particular launch. To lay out the foundation of this claim, it's known that SpaceX's CCAFS Pad 40 integration facilities are only capable of fitting one booster and the strongback (transporter/erector/launcher, TEL) at a time, evidenced both by sourced comments and views inside the hangar.

And finally, a successful Block 5 booster landing on the West Coast, core B1048 on July 25. (SpaceX)

Meanwhile, an unmistakeable Block 5 booster – with black interstage and octaweb coverings – was spotted being transported through Cape Canaveral Air Force Station (CCAFS) earlier this week, just after Falcon 9 B1047 launched (July 21 EDT) and freed up space for another booster inside the horizontal integration facility (HIF) at Pad 40. Given that only one Block 5 booster has been recovered on the East Coast and that B1047 was still out at sea earlier this week, the sooty booster traveling through CCAFS thus has to have been B1046, and it was making a beeline for LC-40.

Just one week before Telkom 4's scheduled prelaunch static fire (July 31), there is no conceivable reason that SpaceX would bring a booster not immediately needed for launch into Pad 40's HIF. As such, it can be all but guaranteed that Falcon 9 B1046 will be reflying for the first time, marking the first critical reuse of a Block 5 booster and hopefully the first of many dozens or even hundreds of reflights for the Block 5 fleet over the next several years.

Autonomous drone ship Of Course I Still Love You arrived at Port Canaveral with Falcon booster B1047 in tow around dawn, July 25. Since then, the booster has been offloaded onto SpaceX's Port Canaveral berth space and is perched atop its stand while crews of technicians and engineers have focused on its legs. It appears that they may be removing them outright, but the fact that nothing has been visibly removed at this point suggests that there is still a chance of leg retraction, an important Block 5 upgrade required for truly rapid reusability. It also appears to be the debut of a brand new connection apparatus at the top of the interstage, purpose likely related in some way to leg retraction.
