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.
The ISS missions, called expeditions, usually last about six months. There are three to six crewmembers on board at all times. Professional astronaut crews come from the U.S., Russia, Japan, Canada and Europe. NASA astronaut Mike Lopez-Alegria has flown the longest U.S. space station mission to date, at 215 days.
