Tha Last Space Mission of Vladimir Komarov

Tha Last Space Mission of Vladimir Komarov

On April 24, 1967, Soviet astronaut Vladimir Mikhaylovich Komarov died in the first fatal accident of a space mission. Komarov was killed when the Soyuz 1 space capsule crashed after re-entry due to a parachute failure. During his time at the Cosmonaut Training Center, he contributed to space vehicle design, cosmonaut training and evaluation and public relations. He was eventually selected to command the first Soviet multiman Voskhod 1 spaceflight that presented a…

Valeri Polyakov and the Longest Single Space Flight

Valeri Polyakov and the Longest Single Space Flight

On March 22, 1995, Russian cosmonaut Valeri Polyakov returned to earth after a 437 days space flight, setting a record for the longest single spaceflight in human history so far, staying aboard the Mir space station.[4] Polyakov did not suffer from any prolonged performance impairments after returning to Earth. In light of these findings, researchers concluded that a stable mood and overall function could be maintained during extended duration spaceflights, such as manned…

The First US Space Station Skylab

On May 25, 1973, the first crew of astronauts reached the US space station Skylab. Skylab was the very first US space station and orbited Earth from 1973 to 1979. A Brief History of Space Stations The first to give serious, scientifically grounded consideration to space stations were Konstantin Tsiolkovsky [7] and Hermann Oberth [8] about two decades apart in the early 20th century. In 1929 Herman Potočnik‘s The Problem of Space Travel was published,…

Bruno Rossi and the Cosmic Radiation

Bruno Rossi and the Cosmic Radiation

On April 13, 1905, Italian experimental physicist Bruno Benedetto Rossi was born. Rossi made major contributions to particle physics and the study of cosmic rays. He was one of the first to use rockets to study cosmic rays above the Earth‘s atmosphere. Finding X-rays from space he became the grandfather of high energy astrophysics, being largely responsible for starting X-ray astronomy, as well as the study of interplanetary plasma. “In any case,…

Vanguard 1 – the first Solar Powered Satellite

Vanguard 1 – the first Solar Powered Satellite

On March 17, 1958, Vanguard 1, the fourth artificial Earth orbital satellite was launched, which was the first solar-powered satellite. Although communication with it was lost in 1964, it remains the oldest manmade satellite still in orbit. It was designed to test the launch capabilities of a three-stage launch vehicle as a part of Project Vanguard, and the effects of the environment on a satellite and its systems in Earth orbit. It…

Recovering the Lost Lunar Photographs

Recovering the Lost Lunar Photographs

Maybe you remember that we had an article on the very first image of the Earth taken from abroad?[1] It was an image taken in 1966 by one of the Lunar Orbiter space probes, which had the task of taking closeup pictures of the lunar surface to find a well suited landing spot for the upcoming Apollo Moon missions. Well, you might wonder, how these photographs came back to Earth. Well, the…

TIROS-1 and the First TV pictures of the Earth from Space

TIROS-1 and the First TV pictures of the Earth from Space

On April 1, 1960, U.S. weather satellite TIROS-1 sends the very first TV picture of the Earth from space. Today, we are used to satellite pictures from the earth in the daily weather report. But, there was a time some 50 years ago, when pictures of the earth from space were still something exciting. TIROS I (or TIROS-1, short for Television and InfraRed Observation Satellite) was the first successful low-Earth orbital weather…

The Deorbit of Russian Space Station MIR

The Deorbit of Russian Space Station MIR

On March 23, 2001, Soviet space station MIR after more than 10 years of operation reentered Earth‘s atmosphere and crashed down in the Southern Pacific. MIR [7] held the record for the largest artificial satellite orbiting the Earth until that record was surpassed by the International Space Station. The First Modular Space Station Mir was the first modular space station and was assembled in orbit from 1986 to 1996. Its famous predecessor, the…
