Passacaglia Edit. The passacaglia is in 3/4 time typical of the form. Bach's ostinato comprises eight bars, which is unusual but not unheard of: an ostinato of the same length is used, for example, in Johann Krieger's organ passacaglia.
He returned to Earth 240 days later aboard TM-7. Polyakov completed his second flight into space in 1994â1995, spending 437 days in space between launching on Soyuz TM-18 and landing on TM-20, setting the record for the longest time continuously spent in space by an individual in human history.
A notable example is Mir, which hosted several long-duration missions of a year or more â including the longest single spaceflight duration of any human to date, 437 days, by Valeri Polyakov in 1994-95. The International Space Station launched its first piece Nov. 20, 1998 and has been continuously occupied by humans since Oct. 31, 2000.
