Nikola Tesla, at age 81, claims in a letter to have completed a "dynamic theory of gravity" that "would put an end to idle speculations and false conceptions, as that of curved space". He states that the theory was "worked out in all details" and that he hoped to soon give it to the world.

1 January
Nikola Tesla informs friend and confidant Kenneth M. Swezey that he has “witnessed his own passing” in a specific vision. He instructs Swezey to remove a collective set of plans, notes and completed blueprints (Experimental works and projects that were lost in a fire; re-created from Tesla's photographic memory) secured in a locked trunk and transfer them to a museum in Belgrade, Yugoslavia. He tells Swezey that the contents of the trunk are to be opened only after Humanity has put an end to it's mistrust across international borders and makes a concerted effort to push into outer space together. Among the contents of the strongbox are a set of functional plans and detailed notes on assembly for a “gravity manipulation apparatus” which will revolutionize air and space travel well beyond the orbit of Earth. The gravity apparatus is the culmination of the last twelve years of Tesla's life developed in secret and well outside of the scientific mainstream; a fact which he had feared would attract the attention of “audiences of interest”. With continuing conflict in Europe and around the world, his fears are justified.

Nikola Tesla is found dead in his room at the New Yorker Hotel. The official cause of death was coronary thrombosis but lingering doubts on this disclosure remain.

Swezey is unable to relocate to Belgrade, Yugoslavia as instructed by the late Nikola Tesla. Fearing the cause is lost, Swezey returns to New York but is met along the route by John M. Onex, who proceeds to tell Swezey that he is Agent 120 a man of the twentieth-century relocated to an alien world far in the future and sent back to this time period to ensure that Tesla's revolutionary work be distributed as intended and for the betterment of the entire world. After a heated period of rational convincing, Swezey agrees to allowing Agent 120 to take the gravity manipulation technology to it's intended destination in Belgrade. Onex instructs Swezey to publish The Tesla Papers detailing the life, times and contributions of Nikola Tesla and charges him with ensuring that said works were proclaimed as a national heritage of human science.

Due to various technical problems, the Manhattan Project experiences delays which make a finished nuclear weapon unavailable until late 1945. The Soviets, under the Zhukov/Molotov junta, grind westward, pushing the fascists back inch by inch. The Germans choose to go on the defensive instead of attacking at the Kursk salient, and the resulting fight, while a narrow tactical victory for the Soviets, leaves their best armored units shattered, and the Germans are able to withdraw into more compact defensive lines. No salient forms in the Army Group Center area that the Soviets can exploit. The Red Army, all the same, keeps grinding relentlessly west, with copious Lend-Lease aid from the US. The Pacific War, North Africa and Italy proceed much as OTL. Preparations for Overlord, the invasion of Normandy, begin in earnest.

The McKinley Rocket Base Incident- USS Enterprise (NCC-1701), conducting historical research by order of the United Federation of Planets Star Fleet, intercepts an interstellar transport conducting Agent 147 “Gary Seven” to Earth. His original task was to sabotage the launch of a suborbital nuclear weapons platform by the United States of America in of itself a response to other nations having already launched similar platforms. At this time, the substantiating logic behind such launches was to maintain the balance of power and mutually-assured destruction in the event of a nuclear weapons exchange by any number of nations. Inadvertently, the Enterprise officers involved delayed Seven's operations as they were hesitant to commit to his assurances on the vital success of this operation. The device is launched and falls to Earth a short time later, but Enterprise officers had prevented Seven from completing the disarming process and the vehicle proceeded to landfall “hot” and armed. At a altitude of 104 miles, the vehicles was successfully detonated, and in the process gained the immediate attention of the entire globe.
This incident galvanizes global concerns about the direction of the 'space race' of the time; whether humanity was racing to space for the benefit of all, or for the sake of ensuring hastened destruction in a nuclear exchange.
The specified role and intent of the United Nations Office for Outer Space Affairs is called into question following the dissemination of the McKinley Rocket Base Incident of 1968. Many seated nations with the United Nations begin to question what role -if any- the United Nations can play in ensuring the end of the proliferation of nuclear arms in Earth orbit.

The Initiative calls for the establishment of an international space agency based within and directly answerable to the United Nations which is charged with overseeing the peaceful exploration and development of space including satellite and planetary bodies within the Sol system. The document is partially framed around the lessons learned from the “McKinley Rocket Base Incident”, which in of itself was an operation carried out by the United States in direct response to similar launches (or attempted launches) of nuclear missile platforms in orbit of Earth. The Initiative calls for the immediate deactivation of these platforms and the safe destruction of existing platforms. It also calls for the peaceful development of space and bodies contained within the Sol system, while appropriating provisions for the effective commercialization of said via entrepreneurship and the private business sector. The Initiative also calls for complete disclosure any and all discoveries made within the Sol system that might directly impact or harm the collective nations of Earth and it's citizens.

The Naturalist Movement is founded by Randolph Warren Green, and rapidly gains strength and influence in the political arena based on the false assumption that cloning had become commonplace and that, in time, the cloning procedure would eventually replace the natural-birth way of life. Randolph Green is the father of Edward Featherstone Green, who will lead a genocidal war against the perceived “clone threat” in 2034-35. Espousing "Genetic and Eugenic Cleansing" of Mankind. The Naturalist Movement (or Party) was formed initially in the United States. This came after the Eugenics Wars, out of former ecologically oriented political parties. These zealous groups propagandized that both cloned and eugenics (specially-bred) humans be permanently disenfranchised. Naturally born humans would replace them in political power.
Conjecture
The Naturalist Movement included in their propaganda famous 20th Century "human wars" novels, including: "Slan", a telepathic world war postulated by A. E. van Vogt; "Time Enough for Love", part of Robert Heinlein's "Future History" series of novels (the novel told the biography of artificially-bred immortal Lazarus Long); and the "Shining Path" of bred-human superiority, written into Frank Herbert's "Dune Chronicles". These books, said the zealots, prophesied the downfall of "natural" humanity. In actuality, there were only about 30 cloned human beings known as of 2030, along with various in vitro and eugenics survivors. This did not sway the NM's propagandists. Also, there was rumored in new-age circles, of isolated "perfect" humans, supposed immortals that had been naturally produced by Earth's biosphere, in the tradition of "Saint Germaine," also known as the "Wandering Jew". However, this notion was discounted even by the Natural Party members as "wishful thinking".
