A German V-2 rocket reaches a record 85 km (46 nm) in altitude.

A German V-2 rocket reaches a record altitude of 85 km, setting a new high-altitude benchmark in rocketry.
On October 3, 1942, a German V-2 rocket soared to a record altitude of 85 km. Developed at Peenemünde under the direction of Wernher von Braun, the V-2 became the world’s first long-range guided ballistic missile. Its liquid-fueled engine and advanced guidance system paved the way for future space exploration. This high-altitude flight demonstrated the missile’s potential for both military and scientific applications. The achievement effectively marked the dawn of the space age and influenced postwar rocket programs in both the United States and the Soviet Union.

The United Kingdom successfully tests a nuclear weapon in the Montebello Islands, Western Australia, to become the world's third nuclear power.

The UK conducts its first atomic bomb test at the Montebello Islands, becoming the world’s third nuclear power.
On October 3, 1952, the United Kingdom detonated its first atomic bomb code-named Operation Hurricane on the Montebello Islands in Western Australia. The device yielded approximately 25 kilotons and was exploded aboard the frigate HMS Plym to assess the effects on naval vessels. This test marked Britain’s entry into the exclusive club of nuclear powers after the US and the Soviet Union. The successful detonation bolstered British national security and spurred further development of the UK’s independent nuclear arsenal. The test also raised environmental and health concerns, leading to debates on nuclear safety and colonial policy in Australia.

Project Mercury: US astronaut Wally Schirra, in Sigma 7, is launched from Cape Canaveral for a six-orbit flight.

Astronaut Wally Schirra embarks on the six-orbit Sigma 7 flight as part of Project Mercury.
On October 3, 1962, US astronaut Wally Schirra launched aboard Sigma 7 in NASA’s Project Mercury program. The mission completed six orbits around Earth, testing spacecraft control and life support systems. Schirra’s precise piloting demonstrated the reliability of manual controls for future manned flights. Data from Sigma 7 helped NASA prepare for longer missions and refine reentry procedures. The success of this flight cemented public confidence in America’s burgeoning space program ahead of Gemini and Apollo.

The Space Shuttle Atlantis makes its maiden flight, carrying two DSCS-III Satellites on STS-51-J.

The Space Shuttle Atlantis embarked on its maiden flight as mission STS-51-J, deploying two DSCS-III military communication satellites into orbit.
On October 3, 1985, NASA launched the Space Shuttle Atlantis on its first mission, designated STS-51-J. Atlantis carried two DSCS-III satellites intended to upgrade the US military's satellite communications network. As the third operational orbiter in the Space Shuttle fleet, Atlantis demonstrated improved reliability and performance. The crew performed critical orbital maneuvers to deploy the satellites into precise geosynchronous transfer orbits. These satellites would go on to bolster secure global communications for the Defense Satellite Communications System III. The mission marked a key advancement in reusable spacecraft operations and military support from space. Atlantis' successful maiden flight paved the way for dozens more missions in NASA's shuttle program.

TASCC, a superconducting cyclotron at the Chalk River Laboratories in Canada, is officially opened.

Canada's Chalk River Laboratories inaugurated the TASCC superconducting cyclotron, enhancing the country's capabilities in nuclear and particle research.
On October 3, 1986, the Tri-University Meson Facility (TASCC) superconducting cyclotron was officially opened at Chalk River Laboratories in Ontario. The cyclotron was capable of accelerating heavy ions to high energies for nuclear physics experiments. It represented a collaboration between three Canadian universities and the Atomic Energy of Canada Limited. Scientists used TASCC to investigate the structure of atomic nuclei and the behavior of exotic isotopes. The facility played a pivotal role in advancing Canada's position in global particle research during the late Cold War era. Over its operational lifetime, TASCC supported hundreds of experiments across nuclear physics, materials science, and radiation biology. Its inauguration marked a significant milestone for Canadian scientific infrastructure.
