Soviet cosmonaut Alexei Leonov made his historic sortie from the Voskhod-2 spacecraft on March 18, 1965, less than four years after his comrade from the original Soviet cosmonaut group - Yuri Gagarin - opened the human spaceflight era.
Leonov’s 20-minute venture outside his spacecraft, attached to a five-meter safety tether, was one of the last of the early Soviet space firsts.
It kept the USSR ahead in the Space Race until American astronauts finally caught up in the second half of the 1960s, culminating in the Apollo lunar missions.
... tass.com/science ... Russian cosmonauts congratulate Earth on 63rd anniversary of space era ...Russian cosmonauts Anatoly Ivanishin and Ivan Vagner, who are staying aboard the International Space Station (ISS), congratulated people of the Earth on the 63rd anniversary of Soviet Union's Sputnik-1 launch, which marked the beginning of the humanity’s space era.
"Dear colleagues, friends and all people of planet Earth. Today, on the 63rd anniversary of the first artificial satellite’s launch, Russian crew members of the ISS Expedition 63 send their greetings to you," Ivanishin said in a video address published on the official website of Russia’s space agency Roscosmos.
… airspacemag.com … New Evidence Shows That Gus Grissom Did Not Accidentally Sink His Own Spacecraft 60 Years Ago …It’s one of the great mysteries of the early space age.
How did Mercury astronaut Gus Grissom, after a near-perfect flight on just the second U.S. space mission, inadvertently “blow” the escape hatch prematurely on his Liberty Bell 7 capsule, causing it to fill with water and sink in the Atlantic?
In fact, did Grissom blow the hatch?
Or was some technical glitch to blame?
Grissom himself insisted he hadn’t accidentally triggered the explosive bolts designed to open the hatch during his ocean recovery.
His NASA colleagues, by and large, believed him.
Years later, Apollo flight director Gene Kranz told historians Francis French and Colin Burgess, “If Gus says he didn’t do it, he didn’t do it.”
And, as writer George Leopold points out in his 2016 biography, Calculated Risk: The Supersonic Life and Times of Gus Grissom, NASA would later pick Grissom for the first shakedown flights of its Gemini and Apollo spacecraft—hardly what you’d expect if the agency had lost confidence in him.
… usni.org … Ships of the U.S. Air Force …Though the United States took a keen interest in the development of ballistic missile technology after World War II, it was not until the Soviet launch of the satellite Sputnik in October 1957 that a new urgency arose.
Within a matter of months the Navy launched its own satellite (Vanguard 1) into orbit, the National Aeronautics and Space Administration was created, and the U.S. Air Force was spurred to invest in a series of ships.
... airforcemag.com ... https://www.airforcemag.com/article/0384tyuratam/ ...The Soviet Union refuses to recognize, and detests, the place-name designation “Tyuratam” affixed by the US government to the principal USSR missile and space test center.
The name Tyuratam has long been accepted throughout the West, but has never appeared in Soviet announcements or publications concerning their deep-space and ICBM weapons programs.
The Soviets will really be disturbed to learn that their spaceport was named by a Central Intelligence Agency official using a Nazi map.
This was not done purposefully, but rather because, in the 1950s, the Soviets wrapped their missile production and launch programs in the strictest secrecy, and the Nazi map was the most accurate map of the area available to the Americans at that time.
The US intelligence community inevitably became aware that the Soviets were constructing a missile test site somewhere south of the Aral Sea.
But the exact location was unknown, and the site became a priority target for U-2 reconnaissance missions.
The U-2 mission tracks were aligned along the main rail line in the area, and the site was quickly located.
The mission launch complex was located in the Bet Pak Dala Desert, south of the Aral Sea, and near the north-flowing Syr Dar’ya River.
The huge launchpad was located at the end of a spur extending come fifteen miles into the desert from the main rail line.
… nasa.gov … 65 Years Ago: The International Geophysical Year Begins …At the height of the Cold War in the 1950s, scientists established the International Geophysical Year (IGY), a global effort for a comprehensive study of the Earth, its poles, its atmosphere, and its interactions with the Sun.
Seven years of planning led to coordinated activities in 11 science disciplines by participating scientists in 67 nations during the 18-month effort that began on July 1, 1957, and ended on Dec. 31, 1958.
The Soviet Union and the United States announced plans to place satellites into Earth orbit during the IGY.
The launches of Sputnik and Explorer 1 began the Space Age and led to new scientific discoveries.
The large volume of information gathered during the IGY required the establishment of World Data Centers to make the results widely accessible.
