Launch
Progress M-56 was launched by a Soyuz-U carrier rocket from Site 1/5 at the Baikonur Cosmodrome. Launch occurred at 16:03:25 UTC on 24 April 2006. Also carried to the ISS was an experimental MIT students-built picosatellite, named SPHERE, that will float inside the station, strictly maintaining its location inside.
Docking
The spacecraft docked with the aft port of the Zvezda module at 17:41:31 UTC on 26 April 2006.{{cite web|url=http://space.kursknet.ru/cosmos/english/cargoes/prm56.sht |first=Alexander|last=Anikeev|publisher=Manned Astronautics - Figures and Facts|title=Cargo spacecraft "Progress M-56"|access-date=2009-06-05|url-status=dead |archive-url=https://web.archive.org/web/20080302004621/http://space.kursknet.ru/cosmos/english/cargoes/prm56.sht|archive-date=2008-03-02}}{{cite web |url=http://www.astronautix.com/craft/proressm.htm|title=Progress M|last=Wade|first=Mark|publisher=Encyclopedia Astronautica|access-date=2009-06-05|url-status=dead |archive-url=https://web.archive.org/web/20090710175743/http://www.astronautix.com/craft/proressm.htm|archive-date=2009-07-10}} It remained docked for 146 days before undocking at 00:28:17 UTC on 19 September 2006 to make way for Soyuz TMA-9.{{cite web|url=http://www.russianspaceweb.com/progress.html|title=Progress cargo ship|last=Zak|first=Anatoly |publisher=RussianSpaceWeb|access-date=2009-06-05}} It was deorbited at 03:28 UTC on 19 September 2006. The spacecraft burned up in the atmosphere over the Pacific Ocean, with any remaining debris landing in the ocean at around 04:14:40 UTC.{{cite web|url=http://www.planet4589.org/space/log/satcat.txt|title=Satellite Catalog|last=McDowell |first=Jonathan|publisher=Jonathan's Space Page|access-date=2009-06-05}}
