A gifted rocket scientist who designed the
first Soviet liquid-propellant rocket, the GIRD-X, which reached a height of
about 75 meters when first flown in 1933, the year that Tsander died from
typhoid fever. He was also the first, along with his compatriot Konstantin Tsiolkovsky
to introduce the idea of solar
sail. In 1924 he wrote, "For flight in interplanetary space I am working on
the idea of flying, using tremendous mirrors of very thin sheets, capable of
achieving favorable results." In the same article he put forward the notion of
Earth-orbiting space stations.
As a high school student in Riga, Latvia, Tsander had been exposed to
Tsiolkovsky's ideas and became fanatical about spaceflight, especially about
traveling to Mars. Apparently he even interested the Soviet leader Lenin in the
subject at a meeting of inventors in Moscow in 1920. During a speech delivered
at the Great Physics Auditorium at the Institute of Moscow on October 4, 1924,
Tsander was asked why he wanted to go to the Mars. He replied: "Because it has
an atmosphere and ability to support life. Mars is also considered a red star
and this is the emblem of our great Soviet Army." In 1931 he became head of GIRD (the
Moscow Group for the Study of Rocket Propulsion) and in 1932, Tsander published
"Problems of Flight by Means of Reactive Devices." Also active in rocket design
at this time was Valentin Glushko.
