Влади́мир Миха́йлович Комаро́в (Vladimir Mikhaylovich Komarov)

16 March 1927 To 24 April 1967.


Vladimir Mikhaylovich Komarov,  Soviet test pilot, aerospace engineer, and cosmonaut.

After flight training during WW2 he served as a fighter pilot. In 1959 Komarov was promoted to engineer-captain and invited to
participate in the selection process for cosmonaut candidate along with approximately 3,000 other pilotswas eventually assigne
to the space program

Komarov was one of the most highly experienced and qualified candidates accepted into the first squad of cosmonauts selected in 1960. He was declared medically unfit for training or spaceflight twice while he was in the program, but his perseverance, superior skills, and engineering knowledge allowed him to continue playing an active role. During his time at the cosmonaut training center, he contributed to space vehicle design, cosmonaut training, and evaluation and public relations.

In October 1964, he commanded Voskhod 1, the first spaceflight to carry more than one crew member. He became the first Soviet cosmonaut to fly in space twice when he was selected as the solo pilot of Soyuz 1, its first crewed test flight.

The Politics behind the space effort resulted in a rush to launch Soyuz 1. Some problems and safety issues such as
"zero-G tests showed that the Soyuz module hatch was too small to allow the safe exit of a fully suited cosmonaut"
were glossed over by the Fearless Leader, and the flight was launched anyway.

per the wiki article,  https://en.wikipedia.org/wiki/Vladimir_Komarov

" On orbital insertion, the solar panels of the Soyuz module failed to fully deploy thereby preventing the craft from being fully powered and obscuring some of the navigation equipment. Komarov reported: "Conditions are poor. The cabin parameters are normal, but the left solar panel didn't deploy. The electrical bus is at only 13 to 14 amperes. The HF (high frequency) communications are not working. I cannot orient the spacecraft to the sun. I tried orienting the spacecraft manually using the DO-1 orientation engines, but the pressure remaining on the DO-1 has gone down to 180."[27] Komarov tried unsuccessfully to orient the Soyuz module for five hours. The craft was transmitting unreliable status information, and lost communications on orbits 13 through 15 due to the failure of the high frequency transmitter that should have maintained radio contact while the craft was out of range of the ultra high frequency (UHF) ground receivers.[27]

As a result of the problems with the craft, the Soviets did not launch the second Soyuz module, from which cosmonauts were to perform an extra-vehicular activity (EVA) to the Soyuz 1, and cut the mission short.

Komarov was ordered to re-orient the craft using the ion flow sensors on orbits 15 to 17. The ion sensors failed. Komarov did not have enough time to attempt a manual re-entry until orbit 19. Manual orientation relied on using the equipped Vzor periscope device, but to do this, Komarov had to be able to see the Sun. To reach the designated landing site at Orsk, the retro-fire had to take place on the night side of the Earth. Komarov oriented the spacecraft manually on the dayside then used the gyro-platform as a reference so that he could orient the craft for a night side retro-fire.[28] He successfully re-entered the Earth's atmosphere on his 19th orbit, but the module's drogue and main braking parachute failed to deploy correctly. The module crashed into the ground, killing Komarov. "

On 26 April 1967, Komarov was given a state funeral in Moscow, and his ashes were interred in the Kremlin Wall Necropolis at Red Square. The American astronauts requested the Soviet government to allow a representative to attend, but were turned down.

I turn over a glass for this heroic Space Pioneer,
3 glasses for the crew of Apollo 1
and 7 more for the crew of the Space Shuttle Challenger.
