Центавр хорошо подошел бы Фалкону в качестве третьей ступени (которой он и является для Атласа с ТТУ), но длина...

Тем более - а куда Ф9 третья ступень? АМС запускать на особо заковыристые орбиты? На ГПО он и без третьей прекрасно обходится...

Да для отлетных можно использовать какую-нибудь маленькую твердотопливную.

Это не кошерно для Маска. Ему надо ионник какой-нибудь. Или ЕМ-Драйв! )))

А для НАСА вполне норм.

О, нет! Не предлагайте Маску эм-драйв. Он же у него заработает и научной картине мира придёт конец!

Также как Раптор "заработает", или быстрее? То есть, то, что Маск на нем заработает - я не сомневаюсь, этож как осла учить разговаривать

The crane team has the cap ready to place on the first stage booster. Not sure if they will attempt to lift it off today or if they are giving extra security before more weather events roll in. #Block5 #Falcon9

Looks like @WaywardBoat is stalking the Block 5, via @murphypak's live stream.

Apparently there is a new lift cap for the Block 5 boosters! When I was at the port last week I believe I got some photos of it.

Booster has been lifted and moved to the pedestal for leg work. Let's see how this is done. Over on the side is a fairing aboard Go Pursuit covered up with a brown tarp. @Teslarati #spacex #falcon9 #portcanaveral #ocisly

Notable vehicles: The SpaceX mystery machine. A mobile command center aka office in a trailer. And the booster transporter. Octagrabber has been put away, out of sight, appears to have worked perfectly. @Teslarati #spacex #falcon9 #ocisly

SpaceX's first Falcon 9 Block 5 returns to port in pristine condition

By Eric Ralph
Posted on May 15, 2018

SpaceX's first launched and landed Falcon 9 Block 5 booster has returned to port after a handful of days at sea, hopefully marking the beginning of a long and storied future of commercial missions. The booster - numbered B1046 - appears to be in extraordinarily good shape, more or less unscathed after a relatively high-energy reentry. Photographer Tom Cross documented the historic return in person at Port Canaveral.

After detaching from the rocket's second stage, which went on to successfully inject Bangladesh's first communications satellite into a geostationary transfer orbit, B1046 reached a peak of around 110 km before reentering Earth's atmosphere. Traveling 2 kilometers (1.2 miles) per second, Block 5 eventually completed a soft landing 500 miles off the Florida coast on the drone ship Of Course I Still Love You. The 25th successful Falcon 9 booster recovery, B1046 marked that historic achievement in proper style, dressed with large, black sections of the new SpaceX-developed thermal protection system, among dozens of other major improvements included in the launch vehicle's "Block" upgrade.

Again, B1046 looks almost pristine thanks to its new thermal protection system, described as a sort of felt that is both extremely heat-resistant and hydrophobic. (Tom Cross)

While not visible, the most significant improvements are likely to be found at the base of the first stage's octaweb - now assembled with bolts instead of welds - in the form of a dramatically improved heat shield around its nine Merlin 1D engines (also upgraded, of course). One of the Falcon recovery technicians showed some exceptional interest in the shield and Merlins, likely documenting their condition in extreme detail to inform engineering reviews of the pathfinder rocket after its first flight test. Per CEO Elon Musk's pre-launch phone call with members of the press, SpaceX means to do an extremely thorough disassembly and analysis of B1046 in order to (hopefully) validate many thousands of hours of design, engineering, modeling, and testing. If those reviews are promising, it's extremely likely that B1046 will be reassembled and flown many more times, perhaps one day becoming another historic monument to SpaceX's reusability program and Block 5 upgrade.

Meanwhile, this mission also marked another routine operation for SpaceX's robotic stage-securing robot, unofficially nicknamed Roomba or Octagrabber. This custom-built robot is used to better ensure the safety of SpaceX's recovery crew by allowing them to remain on an accompanying vessel while securing the booster robotically, significantly lowering the chances of it sliding around or tipping over in high sea states.

Визуально - гораздо меньше копоти. Видимо, сократили время работы двигателя на посадки до самого минимума

Так у этих Мерлинов тяга больше...

Удивлен, что они так и не реализовали систему складывания ног.
