Cancelled after Columbia disaster; would have flown ISS Assembly mission ISS-9A.1, delivering the SPP with 4 Solar Arrays to the station.
Flight delayed after the Columbia disaster. No crew had been named at the time of the loss of Columbia. STS-121 was to have flown ISS Assembly mission ISS-9A.1, delivering the SPP with 4 Solar Arrays to the station. It would probably have returned ISS EO-9 crew (Padalka, Fincke, Kononenko) to earth and delivered the EO-10 crew (Chiao, John Phillips and Sharipov) to the station.
