Quote from the book Challenge to Appolo

[alex fraser]

Sputnik
Work on the Simple Satellite PS-I had continued at an uneven pace since the
development of the object began in November 1956. Between March and August
1957. engineers carried out computations to select and refine the
trajectory of the launch vehicle and the satellite during launch. These
enormously complicated computations for the R-7 program were initially done
by hand using electrical arithrometers and six-digit trigonometric tables.
When more complex calculations were required. the engineers at OKB-I were
offered the use of a "real" computer recently installed at the premises of
the Department of Applied Mathematics at Keldysh 's request. The gigantic
machine filled up a huge room and may have been the fastest computer in the
Soviet Union in the late 1950s; it could perform 10.000 operations per
second. a remark-able capability for Soviet computing machines of the time.
