To bad there will never be a Venus landing in this TL ore any other as it might not be good for the people who land there. The Venera 11 lander survived 127 Minutes at +457°C under pressure of 84 bar of CO2. at altitude of 50km the temperature is +40°C at pressure of 1 bar.

Post 62 The begin of 1990s ... 1992 happen the Germans Union, after three years negotiations the west German Federal Government and East Communist Government, Sign a Treaty were both states form a Confederation, that respect both Government and constitution, form Economic union and Aid. ... ... by'n large ... NICE update
... only "wish" I would have had : - IF ... the german states (and their respective "Big Brothers" take/allow for such a loong negotiation period ...
- I would have preferred a completly "New State" with a new constitution as it was originally demanded by the Grundgesetz preamble but 'conveniantly' by the Ogre from Oggersheim scrapped

IF ... the german states (and their respective "Big Brothers" take/allow for such a loong negotiation period ... The Collapse of East Germany made unification much faster in our Time. In This TL East Germany is healthy functional state, therefor longer the Negotiation period for Confederation were internal border is demolish, but two state stay sovereign. The Negotiation for ECC transform to EU or Bexit took longer...

Post 65 The Wind is changing
The Saturn Shuttle proofed it can lower Launch cost drastic compare to throwaway rockets. with new Shuttle fleet would operate even Cheaper, dropping launch cost under current $2700/Kg Also ELGO-A rocket, a cheap reusable Launcher, thanks its robust construction, but ELGO GmbH looking into reuse ob new rocket under ELGO-X. While British BAE MUSTARD start Service promising cheaper space flight. and India and Japan look into reuse of their Launch rocket.
This put pressure on Competition, who build expensive throwaway rockets: Martin Marietta Titan, McDonnell Douglas Delta and General Dynamic Atlas. Since the Shuttle launch, those companies loosing clients and Payload, special USAF what use intensive the Shuttle. McDonnell Douglas and General Dynamic contract with NASA program compensate their losses. But worst was for Martin Marietta with Titan III rockets during 1980s and start looking for Solution to their problem.
Several options were study, extrem low cost pressure fed Rocket, reusable with parachutes and Airbags, like ELGO A rocket only Bigger. Other is reusable winged first stage based on Titan III hardware, but it engine burn Kerolox instead toxic fuel. not new, the original engines of Titan used Kerolox under Titan I ICBM. Another idea was todo ballistic reuse first stage and land rocket on Ship or platform on sea or near Launch site. UA proposed clustered Solid booster as first stage who return on parachute, land in ocean and be reused.
But question raise how to reach GEO without raising cost ? Martin look into option and found easy solution: NASA SpaceTugs ! Their low cost launcher would bring payload in Low orbit, were Space Tug take it and bring to Geostationary Orbit. But there was catch the Tugs belong to NASA, but Grumman was willing to do Join Venture with Martin for reusable rocket, what let later to Grumman-Martin corp. and build Tug special for this Task, resupply by Martin rocket launching Hydrolox tanks into Low orbit for refuel.
Martin took the wing booster with Kerolox engines, they went also new way, by piloting the Booster return and landing by Remote control. also winged second stage take this approach, making this full reusable Rocket,
Bush Commercialisation of US Space Flight bill, help Martin allot. But this let to wild west situation were start up-companies began to build cheap rockets for access to low orbit, They came to same conclusion like Martin and start to develop various Launch systems. Allot failed like Conestoga (cluster Solid rockets) or Kistler Aerospace and Phoenix Corp. (Single Stage to Orbit). Other like Beal Aerospace (BA rocket family), Scaled Composites (Pegasus), Turax Engineering (Excalibur) and United Technologies Corp. (reusable UA1205 cluster) We’re successful with launching their rockets, but gain profit was another matter, it was the little details overlook, what’s make the difference. First went bankrupt was Pegasus do higher cost launching from Aircraft, compare to far cheaper ELGO-A rocket. Beal Aerospace ran in serious issue, due to the lack of high percentage hydrogen peroxide on the market, needed for BA rocket engines. This limited their plans for large BA rockets and forcing to look for alternative propellants and Engines. While Excalibur became favour for NASA and DoD as Scout and Delta replacement The FAA and NTSB had there hands full with this new market, who soon demand for more Launch Sites, next Kennedy and Vandenberg or Wallops, Federal states like Texas offers coast sides for those new companies, even land lock like New Mexico wanted a share of this new Market. Their Congressmen and Senators made allot pressure in Capitol Hill toward changes in FAA and NTSB regulations in Space Flight. The National Council for Astronautics, took action and handling the issue
From complete unexpected industry came also interest in space: Airliners ! PanAm look into option of commercial spaceflights, either Suborbital or orbital to reach their destination in 90 minute on other side of Earth or to Orbit. They began cooperation with Aerospace companies for Suborbital tourist flights later on option for Launcher for ballistic transport.
In mean time NASA administrator Goodwin face large task, the reform NASA under goal „faster ! better ! cheaper !“ to make ready for new Commercial Market and demands form National Council for Astronautics. special on the wild growing bureaucracy in NASA, what became serious problem.
Saturn Shuttle Phase II In 1995 the first of new Generation Shuttles were deliver to NASA. They look like old ones, but build from new materials like carbon-fibre composite, Aluminium-lithium. Using subcool liquid oxygen for upgraded F-1c and J-2Sb engines. Equip with state-of-art electronics, enable to make first stage operate full autonom, this allow Saturn Shuttle to launch unmanned Nuclear ferries. Making the Saturn Vc obsolete, also lower program cost, do reuse of first stage, but still for Cargo flights the second stage is expendable. NASA made studies on this and came to conclusion, that reuse of this second stage bring too much disadvantage to justification it.
ENERGIA & ALBATROS In USSR the authorities consider mass production of N rockets as better cheaper solution, in fact they drop launch cost over years with mass production. Special in N3 Soyuz and N2 Proton version became cheap and reliable rockets, China though in similar lines and never build reusable Rocket, But Soviet private industry thought differently and oligarchs finance some projects, even in direct competition of N1 Luna rocket ! The biggest is modular Energia launcher by RRK Kurdin, it’s components could put together for various mission profile, and Timofey Yakovlev Kurdin explain in media event, that Energia will be reusable and also offering a Orbiter like US Shuttle ! in record time of 5 years RRK Kurdin build and teste the Energia system.
(Energia first launch in may 1995) Or the Sukhoi Albatros a 1974 concept, scale down and now using engines from N1 rocket, launch from modified freighter with hydrofoil, Despite the insanity of the concept, they build Albatros, it first flight happen in 1995, preparing regular service for State and Private clients next year. The first launch of Albatros was the media event of year, a testimony of resilient Russian and there sledgehammer approach on technical problems…

Post 66 The State of the World in 1990s
Looking back on 75 Years of Revolution. …The Communist Revolution was necessary, it replace the oppressive Tsar system. What enslaves the Workers, until Lenin start the glorious Revolution and liberated the workers. Yes, mistakes were made, like raise of Josep Stalin to power, the political purges, the Holodomor. But then came the great patriotic war, as Nazis try to exterminate us Soviets. Yes it was Stalin who save us, but with grate sacrifices in Blood, he made of USSR a superpower ! After his dead, we needed to rebuild the communist order from ruins of war and Stalin bloodshed.
it was the Great Nikita Khrushchev, who on Stalin ruins build, a new better communist World. Khrushchev open gates of heaven and send Soviets into cosmos, We Soviets were first in Space, first on Moon, We show the world what Communism is capable ! under former Secretary Gorbachev the USSR started a new exciting era towards Utopia for Workers…
Part of Speech held by new General Secretary of Communist Party, Valentina Vladimirovna Tereshkova on 75th anniversary of USSR in 1992.
The USSR became in 1990s one of fast growing economies in World, fast they became the number two behind the USA. But Communism with capitalist economy brought problems: the rise of the Supersrich. Not only was this contradictory to Marxist-Leninist doctrine, they make trouble in the workers paradise. Bragging about wealth and living a decadent lifestyle was one thing, the other was criminal activity, or worse, taking action against the Soviet state! The KGB had a handful of dealings with oligarchs, who belonged to the Russian mafia or wanted to become the ruler of USSR, like Neo-tsarists or democrats. One of those Oligarch is the eccentric Timofey Yakovlev Kurdin, owner of RRK Kurdin, better know as Kurdin Heavy Industry in West. A Spaceflight fanatic, rejected as Cosmonaut, became aerospace engineer, used Gorbachev reforms to gain his first Company and became very rich. notorious known for his contradictory attitude, were he condemn capitalism and praise communism, while being one of the riches men in USSR ! Also he obsess by Spaceflight, Artificial Intelligence, Robotic and Chess. What he single handily push to new levels in USSR. He became very good friend of General Secretary Tereshkova and enjoys a certain freedom of doing, under KGB. Kurdin manage in record time of five years, to develop and build the modular Energia launch system.
Timofey Yakovlev Kurdin in one of his notorious interview with Western journalist
Another issue KGB has end of Project Ideological Subversion, on direct order of General Secretary Tereshkova. This was Long term 1970s program to infiltrate wester nations, demoralising & destabilising them with leftist Ideology until the states collapse, then rebuild them as Soviets states in 2020s. The need of Ideological intact USA and Western Nations als Allies, against hostile China, was vital for survival of USSR. But Tereshkova allow the KGB to experiment on other nations, mostly potential clients for China nuclear help.
Cold War is over, …Right?, …RIGHT ? ? It took a while for both enemies, to realised the Harsch Realty, what to expect with Nuclear War. As American and Soviet scientist discover independently the concept of Nuclear Winter end of 1980s. The large scale destruction of cities with nuclear weapons would release so much smoke, slug and ash. That Sky is block by dark clouds, cooling down Earth for months, starving and killing the survivors. But the results were harsh criticised, but there were historical evidence like Volcanic winter of 1815 and 1830 Also the archaeological evidence that Dinosaur were wipe out by Asteroid, that provoke also deadly Winter. Allot effort went into computer simulation to prove or disprove the Nuclear Winter, only to find their worst fear confirmed.
General Sectary Gorbachev pulled the plug out arms race of both superpower, Is better not play this game he stated. President Bush and General Sectary Gorbachev sign the SALT III Treaty on nuclear disarmament in 1990, (both got Nobel Peace Price in 1991) Follow by SALT IV under General Sectary Tereshkova and President Bush in 1995. But would normalised this relations between the Superpowers ?, actually no. There were still rivalry and quarrels of various kind and there was China, under new rule, Shifted into orthodox Stalinism and expand aggressively into World. Under Doktrin of „Glorious new age for China“
The NATO, Warsaw-Union and there Asia Allies look nervously on this development President Bush push for production of stealth B-2 Bomber and more Hercules Platforms The B-2 was revolutionarily because it could not be detected by Radar
While the USSR push their program for stealth Bomber, Armed either four KH-45 hypersonic missiles or conventional Cruise Missiles or bombs up to 45 tons Also began US-Soviet talks about orbital platform to defend them self and what weapons were allowed under SALT IV. Were the outer space treaty was modified for instalment of Nuclear weapons on Orbital Platforms for defence only.
Also started the Soviet leadership a cleanup in Red Army, after fiasco of Gulf War were soviet tactics failed under Iraq Army. Under Gorbachev, continue under Tereshkova, start to send old Marshals and Generals into retirement and new generation of military came to power. ones with new ideas…
The Chinese Looming Collapse For the People Republic of China, things were not looking good in 1990s, The Nation was now ruled under orthodox ideological Communism, this hamper the Economic and agriculture deeply, just like in People Republic of Korea. in harsh Contrast to USSR and East block, who had Economic Boom, actually China was depending on Imports of USSR ! Also let uncontrolled population rise to 1.3 Billion Chinese to serious problems. The Foot shortage let to „Meat less Day“ initiative were Chinese were force one day in week to eat only vegetarian dish. The current orthodox Communist leaders of China blaming late chairman Lin Biao 1960s reforms as cause of all today problems. With return to Stalinism a la Mao Zedong, they try to get total control over their problems. And introduce new and brutal population control of „One Child Policy“ and death penalty for minor violating of the laws, The Chinese Politburo hope to get population problems this way under control.
Next to that had China expensive military intervention in Afghanistan, a brutal intervention on edge of genocide. and in Cold war with India, one expensive program to dam several rivers in Tibet, to hamper the water supply to India. Another issue of China launching their own Orbital weapon platforms and there nuclear export Also developed China, a Fractional Orbital Bombardment System similar to one the USSR hat tested in 1970s
In order to get Food and certain raw material or political strategic position, China offers Nuclear weapons ! First of those clients was Pakistan, the Enemy of India, China made package deal with government Pakistan in end of 1980s. In Exchange for Chinese nuclear Weapons, Pakistan abandon the Mujahideen in Afghanistan and deliver food to China. with success of Pakistan deal, China look for other Nation that offers needed good in exchange for Chinese Nukes. But the Chinese were not stupid, there Weapon system were manned by Chinese personal and there officers had there orders, In case there Clients „get litte bit funny in there heads“…
But this lead to Iran nuclear weapon program, joining the club of nations with weapon of mass-destruction.
National Crisis Yugoslavia economic profit under Khrushchev 1960s reforms in East block, but Swiss nuclear test change that in 1976. Marshal Tito order nuclear program for bombs and it delivery systems, the program got high priority, after Warsaw Union invaded Rumania to end their program on weapons of mass destruction. Yugoslavia endure political turmoil after dead of Marshal Tito, End 1980s Yugoslavia conduct there first nuclear test, leading to International protest and UN Boycott,
But their Atom-bombs needed delivery systems in form of rocket and bomber, here thing went wrong, Do UN Boycott and the 1980s economic crisis in USSR, Yugoslavia start economic decline. ignored by fast succession of leaders of Yugoslavia. The following economic crisis let cancelation of multi combat aircraft Novi Avion and ballistic missile veliki vulkan and only few warhead were build,
The socialist Federal Republic of Yugoslavia start to crumble, in wake of crisis Nationalism rise, soon follow by racism ugly face ! While Serbian studies claims they were discriminate in Yugoslavia, began in other member states develop a „Serbophobia“. in this two fractions crystallised: Slovenian and Croatian fraction that wanted confederation of Yugoslavia, while the Serbs fraction wanted total dominance over Yugoslavia under Serb rule ! This accumulated in 14th congress of union of Yugoslavia communist in1990, were the members states issue there complaints and demands, The head of the Presidency Milan Pancvski close the congress do turmoil and dispute, announcing he would work on matter, this never happen, Several days later it was Public announce President Pancvski retire do health issue and National Security Council would temporarily replace the Government! At first was confusion in Yugoslavia about this National Security Council and who their member were ?
It was Yugoslavia Military, here some one had brains to realised, the political situation would end in bloody civil war. They not only acted in self-interest, but also on Marshal Tito behalf, who left continuity plan behind: „Apsolutno Jedinstvo“ He knew that after his death, Yugoslavia would face this kind of problems, and wanted his political legacy namely Yugoslavia, survive the test of time.
On emergency congress of union of Yugoslavia, the Military declare the situation: There will be no dissolution of Yugoslavia, either domination by one of it member states, If necessary will Yugoslavia People’s Army will use force and every available weapons, even their small nuclear Arsenal. The Military start arrested extremist and Nationalist on all side of conflict like Franjo Tuđman or Slobodan Milošević That multinational State result to Nuclear black mail to keep nation together was Unique in history… …but it worked !
The U.N. NATO and Warsaw-Union watch careful on this development in Yugoslavia.
Republic of South Africa In end of 1980s the Apartheid system was crumbling, the African National Congress (ANC) fight with growing success against the racist system. The Government in 1990 released Nelson Mandela from Prison, in hope for peaceful solution, But once free, Mandela announced he would take ANC leadership and continue his Communist doctrine, since the Soviets were successful. This made allot in the ruling party nervous, on the other side was power struggles between ethnic groups, about who will represented the Black africans. Also their force Communist agenda supported by Moscow frighten allot people.
Like the „Konserwatiewe Party“ under Clive Derby-Lewis, advocate for Apartheid and Anti-Communist. He united allot Far right bystanders and former special Police C1 members, wanted for crimes against humanity. Also the Afrikaner Weerstandsbeweging Far Right Paramilitary organisation join them, They conspired the murder of Anti-Apartheid supporters and Black political leaders.
10 April 1991, became know as Black Saturday As several men commit murder attempt on several South African Politicians with success, Chis Hani, Nelson Mandela died, bishop Tutu badly wounded, after that the situation escalated.
The hope the multinational state transform to free and liberal Society, ended in bloody Civil war. for next six years South Africa became a Hellhole The Nation got divided into, west the Cape Republic with mostly white and color Population around Capital Cape Town and in East a nation with only native Africans, called IRiphabuliki with capital Egoli (former Johannesburg) The first victims were the Boers under Afrikaner Weerstandsbeweging they were exterminated by sheer mass of africans, who could escape this flew, west wards to Cape region. The victorious Zulus were unable to keep living standards in IRiphabuliki , what descent fast into poverty and chaos, This let to increase of Pirates on East South Africa shore, were Africans attack cargo ships and Ocean liners! This let the biggest disaster in marine shipping as group Zulus pirates highjacked a nuclear power Container ship, Not understanding the technology, there action let to massive reactor meltdown in there Harbor !
A fragile Peace agreement were sight in 1997, What Zulu rulers sign willingly because their had internal problems, they face with poverty and rival ethnic groups of the Batswana, Swazi or Basotho. The IRiphabuliki Government try to get a deal with China for help, but they had little to offer for the Chinese demands…
But biggest worry the World had was: What happen to rest ABC weapons, South Africa had developed ? CIA Analyst had indication that Cape Republic sold some of their Mass destruction Weapons to finance their Civi war effort ! But to who ?

Post 67 European Space Program in 1990s With creation of of European Union (EU) change allot for European Space Research Organisation in 1992 By majority vote by the politicians, ESRO became Europan Ministry with stable budget, with the British Jason Webb as new Director. They gain allot of Money and additional research program and finally they would do serious programs with their allies ELGO GmbH and BAE. ELGO GmbH with there successful Modular rockets ELGO A/B Series, prepare the C series, a modular Hydrolox stages With High performance Engine HDTW They would drastic double the Payload compare to ELGO B series, who use storable propellant. But ELGO conduct series of test of ELGO-X Concept in 1993. on reuse C series and if ballistic Reuse is commercial viable, use this technology. BAE on other hand, build reusable MUSTARD and successful tested it in Australia and British Government were in negotiations with French for launch site in French Guiana, For Equator orbit Mission, while Australia served for Polar military mission, who government were in negotiations with British Government to build launch site in Darwin north Australia. ESRO director Jason WebbWith MUSTARD had ESRO finally a Spacecraft that could bring Europeans into Space independently from USA and USSR. Jason Webb not hesitate to create European Astronaut Corps, ignoring NASA Group E of Europeans. He also intervene in British French negotiations to get Launch pads for MUSTARD in French Guiana, Here Webb was ruthless, he not care about British-Australian relations. ESRO wanted also own Space Station, idea the French and Germans favour, Building a European Station make sense, since NASA de-orbit Starlab and USAF restricted access to Bold-Eagle Station in GEO. (In this time Space Base Olympus was only proposal at Space Task Group at White House) Alternative flights to USSR Space stations, again problematic, since Soviets insist that Europan Personen are train in USSR and Launch on Soviet Spacecraft. Also had Mir restricted areas for Military purpose, what limited the Europeans on board operation, this also infuriated Webb. So ESRO launch SpaceLab in 1995, it based on french SOLARIS concept, modified for manned operation, first temporary, later Permanent occupation of 3 astronauts. Another goal were a Base on South pole of Moon, here ESRO found a Partners in USA and Japan. In Mean time Earth orbit filled with manned Space Stations Next US Bold Eagle station in GEO, the Soviet Mir complex, the Chinese Tianhe, Europa SpaceLab, came Japan JASDA with Kibō station serve with Fuji space capsule. JASDA or Japan Space Development Agency, made long way from 1970s, with first copy of the US Delta Rocket now build own rockets the H-II and H-IIB in 1990s the Fuji capsule was compromise since Development of Spaceplane HOPE and Kibō project was too expensive for their Budget. India conducted Manned space flight with there Gaganyaan capsule, planning also small space station mostly for military applications. While Private aerospace companies look into option to launch their own commercial space station. Interview with Walter Kleinau Head of ELGO-X projectInterviewer: You are part of MBB Team that work for ELGO GmbH ? Kleinau: yes ! we are responsible for ELGO Reusable study or how we call it ELGO-X. ELGO-C with it HORA modular upper stage is unique launcher but, ELGO want to reuse it, so MBB got Order for study options for Reuse. Interviewer: There allot study by US companies like Titan V by Grumman-Martin corp. Dit this influence you work ? Kleinau: No, we started in 1982, far ahead of those studies, we came to conclusions that ballistic reuse would better options, Dropping everything unnecessary stuff, like Wings, jet engines etc. We not even needed a heat shield for first stage, just aerodynamic cover, and a barge were first stage landing on. Interviewer: Why landing on Barge on ocean ? ELGO-A splash in ocean and is recover. Kleinau: Those are robust build pressure fed rocket, impact into ocean and swimming in seawater dosen’t matter for them. But the ELGO-C series is to sensitive for that. Interviewer: Is that reason why the ELGO-B are not recovered ? Kleinau: Yes and No, unlike ELGO-A, is mainly that ELGO-B stages return unstable, preventing secure deployment of parachute, Do heavy engine block of stage, We tried to recover them in 1970s but failed, what let to ELGO-X project. Interviewer: So you solved the stability problem ? Kleinau: yes by putting the Frist stage inside Aerodynamic container, that allow stable return to Earth. The biggest problems were the mass of this container and also restart and throttling the HDTW engines for landing. The colleague of the „Raketentriebwerks Abteilung“ allot problems during testing to achieve the needed demands. Interviewer: Why ? Kleinau: The HDTW is unique rocket engine, it use the combustion chamber to power, direct the Turbopumps, eliminating the massive preburner such engine need. Interviewer: One moment, how power the combustion chamber the Turbopumps ?! Kleinau: The turbine that power both Turbopumps is installed in the combustion chamber itself, connected by vertical drive shaft with the pumps. This allow a compact vertical engine construction, special since it run on 150 bar pressure ! But give also advantage of stepless throttleable Thrust, ideal for needs to land the first stage on barge ! Interviewer: This gave some problems ? Kleinau: Yes, problems were restart of HDTW for slow down and landing burn, the colleagues lost allot engines during restart testing, but finally got it work. Interviewer: What is future for ELGO-X now ? Kleinau: It will enter service as ELGO-D For moment it will reuse the first stage, what is adapted for it mission, while second stage HORA is expendable. But we will in future build a reusable second stage from HORA for ELGO-D with option to bring payload from space ! Interviewer: What Payload ? Kleinau: Various types mostly Satellites or cargo containers from Spacelab and material not suited for manned MUSTARD shuttle to return. What are no problem for unmanned ELGO-D! Interviewer: Thanks for interview mr Kleinau Kleinau: your welcome, Goodbye

Post 68 Fusion Drive ?
After fiasco of Aelita-1 were Soviet ended second on Marsrace, do lack powerful Ion engines. The Soviets started a Research and Development on New Nuclear engines. Soon they drop classical Solid Thermal nuclear Engines design and look for more powerful systems like Gas-core reactors. looking for engine in range of specific Impulse of 100000 sec minimum, needed for a Jupiter mission.
Another approach was „High Thrust“ ion engine until 1990s the Soviets manage to double their Ion engines thrust by using Hall Effect.
On gas core reactor was already EU-610 program. in fact since 1970 the Keldysh Center developing a gas core reactor EU-610, who went critical in 1972 and in 1978 reach maximum temperature during test runs. Instead of solid fuel rod, use this type of reactor, helium mixed with Uranium-fluoride compound in gaseous state, This allow to operate the Reactor on far higher temperature as conventional nuclear reactors up to 70000 degree Kelvin ! During the 1980s they focus on development for civilian gas core reactor with MHD Generator. But after Aelita-1 fiasco, EU-610 got in focus of soviet Ministry of Space as Rocket engine RD-0610,
RD-0610 is closed Gas core reactor operating under 100 MPa pressure, using Hydrogen as remass and Lithium for better heat transfer to the Hydrogene, if you overcome the issue of the highly corrosive Uranium-fluoride compound that damage the reactor core.
Another project is Puls Fission/Fusion Plasma Drive or IPDYS how the Soviet abbreviated it. Nuclear reactor provide power to make from Deuterium/Helium3 a high energy plasma, that accelerated by magnets. Theoretical it could reach ISP 12700 sec and even more. but technical it was not Fusion engine, since it main power comes from nuclear Fission reactor, not by fusion reaction of Plasma ! And the biggest issue with IPDYS was need for Helium3 a very rare isotope of Helium.
Then happen a propulsion break true from project no one expected it. USSR was Experimenting into Fusion technology, like testing Tokamak reactors under I.E. Tamm and A.D. Sakharov. But also Inertial confinement Fusion with Laser, the Soviet invested heavy in Lasers during 1980s for ballistic Missile defence. Based on Work of Polish military engineer General Sylwester Kaliski, They experimented with pulsed laser boosted to X-ray, but it’s result were disappointed for Missile defence. But for Fusion experiments this laser was powerful enough, with success able to produce more energy as put in ! It still was long way for working Laser Fusion Reactor for Energy production, but as rocket engine feasible. So work on RD-1000 or Kalisky’s engine started
In USA had Los Alamos Lab with Timberwind of new generation solid Nuclear thermal engine and we’re thinking in similar lines. Also more powerful concept were study and tested, like Gascore reactor or Fusion power, also on Magnetoplasmadynamic engines.
Until British Rolls-Royce proposed the Serpent, a Nuclear engine with ArcJet as Afterburner. Here Lithium is heated by reactor, then give that Heat to Helium what power a Turbine for electric generators, then transfers heat to Hydrogen, With electricity powers ArcJet in side thrust Chamber full of hot hypogene, now supercharged by electrical arc. Serpent hat theoretical 40% higher specific Impuls with far higher thrust as nuclear Timberwind engine ! With far lower radioactivity as Timberwind engine, do use of Lithium/Helium cooling to indirect heating Hydrogen, But Serpent was heavy current study show weight of 45 tons engine, while Los Alamos Laboratory and Rolls-Royce were confident to reduce that mass. And there was another issue the turbine generator produce the electrical power has capacity far below of reactor output.
But behind scenes, happen sinister plots, the CIA, KGB and China were try get information about the other programs and gain needed technology from other side… …like Superconductor needed for some engines.

Post 69 Exploration of Solar system
in begin of 1990s under President Bush the planetary program flourish with programs for Outer planets Orbiter, Mercury Orbiter, a Titan lander
but the following administrations not focus on planetary science and even NASA dit budgets cutting or cancel Programs. do lack of political interest and need for money for other programs like upcoming space Base or Moon base. And Ares missions to Mars, who were for moment the only scientific exploration of planet Mars, to make matter worst there is no even clear vision, what to do after end of Ares Program.
Program like Outer planets Orbiter could be saved, do it international collaboration with Germany Confederation With success of Galileo Jupiter Orbiter, came proposal for Probes with common design, hardware and software, based on Galileo orbiter experience, but with lower cost. What make the proposal so unique was also collaboration by East Germany scientist and industry that provide hardware and sensors for SOVCOSMOS ! Planned were Four primary and 3 secondary missions: Jupiter Orbiter with atmospheric probe Saturn Orbiter with lander for Titan Uranus Orbiter with atmospheric probe Neptun Orbiter with atmospheric probe
Comet Rendezvous with Asteroid Flyby Comet or Asteroid Sample Return mission Pluto Flyby
The first canceled was Jupiter Orbiter, the Logic of White House and Berlin was there is Galileo Jupiter Orbiter is still operational. Follow by Pluto Flyby mission and Comet or Asteroid Sample Return mission. It had some irony that Jupiter Orbiter, was saved by ESRO, who proposed to pay for completion of Probe and Launch under Name Marius.
First to be launch was Cassini toward Saturn, carrying the Huygens lander for Titan. follow by Herschel with atmospheric probe Bode for Uranus and Adams with atmospheric probe Le Verrier to Neptune.
Comet Shoemaker-Levy-Marsden
This Comet was discover in 1993 near Jupiter as he break up into 21 fragments ! Calculations by Shuichi Nakano show that Comet was rippt into pieces by gravity of Jupiter and fragments will impact the planet on July 1994 Confirming the theory of Yevenly myrgjol Sapozbik about craters of Davy in Mare Nubium. (who Sapozbik personal visit with Soyuz 26 mission in 1974)
A race startet to investigate the event at Jupiter.
The Soviet hat two Gercuels-Yupiter probe in orbit of Moon Europa, but there were primarily Radar scanner to study the ice surface of Europa. The German/US Probe Galileo orbit Jupiter, it could observe the impacts, but the old probe had also problems: the data Tape recorder began sticking, refuse to playback Data !
ESRO Probe Marius was still one astronomical unit away from Jupiter, too far for useful investigation. Pioneer 12 sadly already made it 6th fly by at Jupiter on 1993 February 02 and would return in 1996 while ESRO Solar probe Odysseus would return to Jupiter only in 1999. The Soviets gave second Gercuels-Yupiter probe new instructions, it shut down radar and reactivate ion engines spiral out Europa orbit, pasting the orbit of Moon Io, into closer orbit on Jupiter.
The Impacts gave Mankind Taste of Armageddon, allot of people look into night sky, wondering „Are we the Next ?“ and Hollywood brought Movies were such asteroid threaten to impact Earth. Some of those movies frighten politician what let to international project „Spaceguard“. (NASA, SOVCOSMO, ESRO and JASDA under U.N.) It goal scann the sky for Asteroid that could hit earth and find way to prevent it.
First series of Spaceguard probe were send to various asteroid near Earth and asteroid belt Remember Comet Rendezvous with Asteroid Flyby proposal ?, NASA built from Spare parts modified outer orbiter for this mission and launch it as Spaceguard 5 With bad surprise, several asteroid are pile of rubble instead of Solid object, what would make interceptions difficult.
Other proposed those pile of rubble could used for mining materials, leaving only smaller remains like slag
Hollywood jump on Media Hype and produce two Movies „Armageddon“ and „Deep Impact“ the typical disaster Movie. But it was Soviet movie „Flight of Aleita“ by Yuri Pavlovich Moroz, that stole the Show. It depict a Soviet attempt to stop Asteroid hitting Earth, were it four man crew fight against the Odds and technical failures, in order to succeed at any cost. What makes „Flight of Aleita“ so exceptional, is that SOVCOSMOS provide full collaboration, not only they shot movie in Starcity, but also scenes in Space ! NASA was bombarded with request form filmmakers like Ron Howard, James Cameron or Tom Cruise, for filming in Space, on board of US Spacecraft. Administrator Goldwin out right refused them.

Post 70 1995 in Space NASA Space Base Planned as Space Station 5 in 1970s, it was design as very large Space Station with up 100 astronauts on board. Over the time with technological development and experience of Skylab, Starbase, Moonlab, Bold-Eagle , change radical this. The base would operate with 24 Astronauts and could occupy 48 astronaut if needed. since it will serve as transportation hub toward other stations an upcoming moon Base it was build from 4 improved Space Station Modules and Various Application and Science Modules (ASM) The Artificial gravity module was abandoned do high cost and technical difficultly, also possible interference in function of Space Base. The planned nuclear power supply was abandon in favour of Solar power do safety reason, but with new power-source: Solar-thermal Naming the Space Base let to political event, Republicans demanded from NASA to name station Richard Nixon After the 37th President of USA who die in 1994, His Politic let to US success in Space-Race Administrator Goldwin made made a judgment of Solomon, the NASA HQ in Washington D.C. war rename to the Richard Nixon Center While Space Station 5 got name Olympus. 50 km behind Olympus position is new propellant depot, it serve Space Tugs, nuclear ferry and upcoming successor. On Issue of Moon Base NASA was able to secure support by ESRO and JASA, turning Bush proposal form US to International Base however the USAF were not so happy about international Partnern in this Projects Ares 5&6Launch in December 1994 this mission was to explore the Regio of Mars, they were Follow by Aelita-3 Mission the US mission had Novum two woman on board Natalie York on Ares 5 and Sally Ride on Ares 6 For Ride it was her last spaceflight , after that she will work in Richard Nixon center. Target for Ares 5&6 is impact crater Gusev in the Aeolus quadrangle of Mars, on way up happen mishap on Mars, the sample collector rovers Spirit got stuck in soft sand unable free it self. 8 km away from Ares 6 landing site there was debate between Crew and Ground control to use MEM rover to get to Rover for Samples, Mission control refuse permission to use the manned Rover to get samples. Main problem: Spirit nuclear battery, normally the Rover would put down the Sample container and drive to safe distance. Here the Astronauts hat approach on path that lies in shadow shield of nuclear battery grab the Container and get away quickly. something too difficult in this Mars Terrain proposal to use sample collector rover opportunity to recover spirit sample container were not feasible, it would take over year to complete this, at that time Ares 5&6 do there Venus fly by back to Earth. On day 3 after landing Rover Opportunity delivers his container at MEM of Ares 5. The scientific Results were surprising the rocks were mostly volcanic Basalt Under the sand are layers ironsulfate with high nickel content, this ironsulfate has very litte cohesion, preventing the rover’s wheels to gain traction. That was reason Spirit got stuck and later the MEM rover of Ares 6, were 2 astronauts had to walk on foot back to MEM Aelita-3 had two different targets; Phobos and Deimos the moons of Mars. To land on Moons was consider problematic do there low gravity, they study several options, even to equip a pole on Aelita-3 and use as anchor, by ramming it into Moons surface. in end they took left over LK from first Lunar program and refurbish and modernised them for landing there. to move over moons was another issue the gravity is too low for any use by hand or feet So they used Cosmonaut propulsion system SPK 25KS, however the Cosmonaut had to make EVA out side LK to 25KS before use. Next to this, Aelita-3 was equip with various probes and sensors to explore the Moons, one of the complex manned mission the Soviets made until now. First spiral Aelita-3 down on Ion engines into orbit of Phobos, then match it speed with Phobos, from here they use the manoeuvring thrusters to get closer to Phobos Here drop various probes on surface of the moon while cartographic its surface, follow by manned landing, After this move Aelita-3 to the moon Deimos repeat the mission of Phobos and then return to Earth. Aelita-3 Approachs to Phobos So the plan, on arrival things were different, the Moons surface dust layer swirl up on landing of Probes or LK, hamper view like fog. The Cosmonaut Grigory Vladimir Kuznetsov had to wait one hour until dust settle enough for EVA. The LK Drill was disappointment it drill into dust layer but it was too thick to reach lower surface of Phobos. However hat another target to reach near by Phobos Monolith a building size bolder sticking 90 meter out dust layer This was debris from impact on Phobos, if lucky the soviets get samples from Phobos, if not, from object that hit it. Kuznetsov on 25KS reach the Monolith and was able to hammer samples out of it. After difficult Mission leave Aelita-3 toward Deimos, only have same problems with dust layer here. The soviets finding on two moons were mysterious, there identical in composition of C-type Asteroid So identical the soviets scientist believe that Phobos and Deimos were once one object. They had already discover that comets Halley and Churyuumov-Gerasimenko-67P are contact binary. Somehow Phobos/Deimos enter orbit of Mars brocke up and enter in their today orbit, but how they enter into stable orbit around Mars is unsolved mystery. Also why they are cover by thick layer of dust is difficult to explain. Radar scann show no cavity inside the moon but a porous structure mixed with pebbles and bolders. January 1995 Ares-5 & 6 on return trip made Venus Swing-by were they drop series probes to explore Venus Atmosphere. Also Aelita-3 made Venus Swing-by dropping probes Venera 17 & 18 All three Spaceships return safe into Earth orbit during summer 1995. On Soviet side the Energia booster was launch successful The modular booster envision by Kurdin Heavy Industry was pride fo Timofey Yakovlev Kurdin. launching from 10 tons with one booster, to 20~40 ton up to 150 metric tons with various configurations of Energia booster. This rocket was serious competition for N1, N2 and N3 rockets from NPO Korolev. To make matter worst, the General secretary Tereshkova and Red Army supported Kurdin in Energia program, the logic was simple: Two launch systems could bring double so much into Orbit and Moon. Also tested Kurdin Heavy Industry a Space Shuttle boilerplate on Energia that after one orbit manage to land unmanned at Cosmodrom Note: Grigory Vladimir Kuznetsov is homage to Cosmonaut from For All Mankind
