Space innovation

No paint. Carbon fiber. 300kg to LEO. $7.5M.

Vehicle: R-7 family, likely Vostok or Soyuz monument. 4x conical boosters visible, 1x central core. This exact layout launched Sputnik 1957, Gagarin 1961, and still launches Soyuz crews in 2026 Engines: Boosters: 4x RD-107 total. Each RD-107 = 4x main combustion chambers + 2x vernier chambers = 6 nozzles per booster. 83.5 tons thrust each. You can see 4x big bells + 2x small verniers per booster here Core: 1x RD-108 = 4x main chambers + 4x verniers = 8 nozzles. 79 tons thrust. Verniers gimbal for roll control Total: 20x chambers, 16x big bells + 4x small verniers on boosters + 4x small on core. All kerolox, gas-generator cycle, 309 sec ISP Why so many chambers: Soviet manufacturing in 1950s couldn't build one big 80-ton chamber reliably. So Korolev clustered 4x 20-ton chambers fed by 1x turbopump. Same trick as Saturn I. RD-107/RD-108 are "4-chamber" engines. R-7 = 5x engines = 20x chambers Staging: Boosters burn 118 seconds, separate via “Korolev cross” as core continues. Core burns 301 seconds. Upper stage takes over to orbit. All 20 chambers light on pad — no air-start risk Erector: Red = transporter-erector arm. Rocket held by 4x arms gripping interstage. At liftoff, counterweights swing arms away. Same system used at Baikonur Site 1/5 "Gagarin's Start" and Site 31/6 today Context: This monument shot is likely VDNKh Moscow or Samara. Real flight version looks identical. Soyuz-2.1a/b uses upgraded RD-107A/RD-108A = 85/80 tons thrust, digital controls, same 20x nozzles

Vehicle: Vostok-K 8K72K — 30.8 m tall, 287 tons fueled. Derived from R-7 ICBM. 4x conical strap-on boosters + sustainer core + Blok-E upper stage. Total 20x nozzles at liftoff Engines: 4x RD-107 on boosters, 83.5 tons thrust each with 2x verniers. 1x RD-108 on core, 79 tons thrust with 4x verniers. Upper stage = RD-0109, 5.6 tons. All kerolox gas-generator, 309 sec ISP. Liftoff thrust = 413 tons = 4.05 MN. Boosters sep at T+118s Markings: "ВОСТОК" = "East" — named for the first crewed flights. "СССР" = USSR on the Vostok 3KA capsule fairing. Red nozzle caps = safety covers, removed before fueling Erector: Bright red = Soviet rail transporter-erector. Rocket rolls out horizontal from MIK assembly building, erected at Pad 1/5 "Gagarin's Start". 4x support arms grip the rocket at the booster/core interstage. Arms retract at T-0 when thrust > weight Flight record: Vostok launched 6x crewed missions 1961-1963: Gagarin, Titov, Nikolayev, Popovich, Bykovsky, Tereshkova. Also 13x Zenit spy sats + Luna probes. 163x Vostok family flights 1958-1991. 0 crew lost on Vostok Legacy: R-7 family = 1,700+ launches 1957-2026. Evolved into Voskhod, Molniya, Soyuz, Soyuz-U, Soyuz-FG, Soyuz-2 flying today. Same pad, same erector, upgraded engines. Longest-serving rocket ever

Vehicle: Vostok-K 8K72K— Direct descendant of R-7 ICBM. 30.8 m tall, 10.3 m wide at base, 287 tons fueled. 4x strap-on boosters + core stage + upper stage. Total 20x combustion chambers firing at liftoff Engines: Boosters = 4x RD-107, 83.5 tons thrust each. Core = 1x RD-108, 79 tons thrust. Upper stage = 1x RD-0109, 5.6 tons thrust. All kerolox, gas-generator cycle, 309 sec ISP. 20x vernier chambers for steering. Total liftoff thrust = 413 tons = 4.05 MN Payload: Vostok 3KA capsule on top. 4.7 tons, 2.3 m sphere. Carried Yuri Gagarin for 1 orbit, 108 min, Apr 12, 1961. Also launched first 6 cosmonauts + Luna probes + Zenit spy sats. 163x Vostok flights 1958-1991 Transporter-Erector: Red structure = rail-mounted erector. Rocket shipped horizontal on train, erected at pad, held by 4x arms until thrust > weight. Same system still used for Soyuz in 2026. This monument shows rollout config Location: VDNKh = Exhibition of Achievements of National Economy, Moscow. This Vostok monument installed 1967 for 50th October Revolution anniversary. Still there in 2026. Background = Pavilion No. 32 “Space” Legacy: R-7 = 1,700+ launches 1957-2026. Soyuz-2 uses same core/boosters with RD-107A/RD-108A upgrades. Longest-running rocket family. 0 failures for Gagarin, Tereshkova, Leonov. Reliability = 97.4% over 69 years

Left: R-1 cutaway, 1950— Soviet copy of German V-2. 13.6 tons thrust, ethanol/LOX. Range 270 km. Tanks + turbopump visible. Yellow = tail fin structure. 92% V-2 parts. Flew 1948-1957. Taught Soviets how to build missiles Second: V-2/A-4 replica— Nazi Germany, 1944. First object in space. 25 tons thrust, ethanol/LOX. 88 km altitude. Von Braun’s design. Captured hardware = foundation for both US Redstone + Soviet R-1. 3,000+ fired at London Third: R-7 ICBM/Sputnik stage— 1957. 4x RD-107 boosters + core RD-108. Total 20x chambers, 4M lbf. Launched Sputnik, Gagarin, Soyuz. 1,700+ flights. Still flying as Soyuz-2 in 2026. Longest-running rocket family ever Fourth: Proton UR-500 core— 1965. 6x RD-253 engines, 1,050 tons thrust. UDMH/N2O4 = toxic, storable. 425 flights, retired 2024. Launched Salyut, Mir, ISS modules. Replaced by Angara A5 Right: Energia strap-on— 1987. 1x RD-170, 740 tons thrust = most powerful kerolox engine ever. 4x boosters + core = 3,500 tons thrust. Launched Buran once. Cancelled 1993. RD-170 split into RD-180 for Atlas V, RD-191 for Angara Engine bottom right: RD-253 for Proton. 166 tons thrust, staged combustion, UDMH/N2O4. 1965-2024. 2,550 built. Energomash built every major Soviet/Russian engine: RD-107/108, RD-170, RD-180, RD-191

Modularity: All variants use the same URM-1 first stage = 2.9 m diameter, 25.1 m tall, RD-191 kerolox engine, 192 tons thrust. Cluster 1x for A1, 3x for A3, 5x for A5. Lego approach = common production line. Second stage = URM-2 with RD-0124A, 30 tons thrust Angara A1.1: Rightmost, smallest. 1x URM-1. Payload = 2 tons LEO. Never flew — cancelled. Used for suborbital tests only Angara A1.2: Second from left, white tower = launch escape system. 1x URM-1 + URM-2. Payload = 3.8 tons LEO. First flight Jul 9, 2014 from Plesetsk. 3 flights as of 2026. Replaces Rockot/Kosmos Angara A3: Middle right, 3x URM-1. Payload = 14.6 tons LEO. Never built. Cancelled 2018. Gap between A1.2 and A5 too small Angara A5: Leftmost + second from right. 5x URM-1 + URM-2. Payload = 24.5 tons LEO, 5.4 tons GTO. First flight Dec 23, 2014. Heavy-lift Proton replacement. 8 flights as of 2026. A5M upgrade = 27.5 tons LEO, flying 2024+ Context: Proton uses toxic UDMH/N2O4. Angara = kerolox/LOX + hydrolox upper. Cleaner. All-Russian supply chain after Ukraine lost Zenit. Launched from Plesetsk + Vostochny. Vostochny pad opened 2024. Commercial orders = near zero. Mostly military As of 2026: 11x Angara flights total. A5 rate = 1-2 per year. Starship flew 10x in 2025-2026 alone. Angara A5V with hydrolox upper stage = 38 tons LEO, NET 2028. Oryol crew vehicle planned but no Angara crew flights yet

Raptor Vacuum (RVac): Same powerhead as sea-level Raptor, but massive nozzle extension. Sea-level = 1.3 m nozzle, 280 tons thrust. RVac = 2.3 m nozzle, ∼258 tons thrust, 380 sec ISP in vacuum. Expansion ratio ∼107:1 vs 34:1 for sea-level. Higher ISP because exhaust expands fully in vacuum Hardware details: Green = copper alloy chamber, regenerative cooling. Silver = corrugated nozzle extension, radiation-cooled niobium. Nozzle doesn’t need active cooling in space — vacuum prevents convection. Top = turbopump + preburners. Numbers 384, 386 visible = serial numbers. Raptor 2 RVac shown here Why 2 engine types: Sea-level Raptors gimbal ±15° for steering + landing. RVac fixed, higher efficiency. In atmosphere, RVac over-expands = flow separation = RUD. In space, sea-level underexpands = wasted energy. Ship fires all 6 at stage sep, cuts sea-levels for orbit, restarts for deorbit + landing Scale: Gwynne = 1.65 m. RVac = 4.6 m tall vs 3.1 m sea-level. Nozzle alone = 2.3 m diameter. Ship = 50 m tall, 9 m diameter. 6x engines = 1,500 tons thrust. 100 tons to orbit. 100 tons to Mars with refueling Context: RVac first fired May 2020. First flight = Flight 2 Nov 2023, all 6 lit. Flight 3 Mar 2024 = first orbital burn. Flight 10 Aug 2026 = Ship ocean land, all 6 RVac relit in space. Raptor 3 RVac = 285 tons, flying 2025+ Manufacturing: McGregor builds 1x Raptor per day as of 2026. 500+ total built. RVac production = ∼25% of line. Each tested 10-20x before flight. Cost = $2M vs RS-25 $100M. Reusable 100x design goal

Top: Booster 4 + Raptor 1, Aug 2021 Plumbing nightmare: Green bells = copper alloy chamber. Exposed manifolds, flex joints, sensor harnesses everywhere. Each engine = 1,600 kg. Thrust = 185 tons, 330 bar. Shielding needed: Tarps top left/right cover the fragile bits. Raptor 1 couldn’t survive reentry heat without dedicated shields. Gimbal boots, wiring, COPVs all exposed. Reliability: SN range RB5, RB25, RB26 visible. R1 had ∼50% test stand failure rate. Flight 1 Apr 2023 lost 8/33 engines. 3 exploded. 185 tons x 33 = 6,105 tons = 13.4M lbf. Less than Saturn V. Never flew: B4 stacked with Ship 20 Aug 6, 2021 for fit checks. Scrapped after FAA delays. BN7 flew Flight 1 instead. Bottom: Booster 19 + Raptor 3, 2025 Integrated design: Black bells = regenerative cooling integrated into nozzle. No external pipes. No shields needed. Engine _is_ the shield. 40% fewer parts vs R1. 35% mass reduction. Performance: Thrust = 280 tons, 350 bar. 280 x 33 = 9,240 tons = 20.3M lbf. More than 2x Saturn V. Thrust-to-weight >200. F-1 = 94. RS-25 = 73. ISP = 380 sec vacuum. Manufacturing: Numbers 42, 99, 63, 72 = SN range. Raptor 3 = 3D printed, channel-wall nozzle, integrated controllers. $2M per engine. RS-25 = $100M. 1 per day at McGregor. Goal = 4 per day. Flight proven: Raptor 3 first flight = Flight 6 Nov 2024. BN12 caught Flight 5 Oct 2024 on Raptor 2. BN14 caught Flight 10 Aug 2026 on Raptor 3. 5x Booster catches as of 2026.

Full-flow: Oxygen-rich turbine. Fuel-rich turbine. Both at 800°F. Neither melts. Raptor evolution: Raptor 1: Plumbing nightmare. Raptor 3: Plumbing? What plumbing? Scale: That’s a man. That’s an engine. There are 33. Cost: Shuttle RS-25: $100M Raptor 3: $2M 50x cheaper. 100x flights. Mars: Burns methane. Makes methane on Mars. Comes home. Staged combustion: Russia said it couldn’t be done. America proved it couldn’t. SpaceX did it anyway.
