ISS Expedition 28 is the mission name for the 28th long-term crew of the International Space Station (ISS). The mission began with the decoupling of the Soyuz TMA-20 spacecraft from the ISS on May 23, 2011 at 21:35 UTC . The end was marked by the decoupling of Soyuz TMA-21 on September 16, 2011 at 0:38 UTC.

• Satoshi Furukawa (1st Spaceflight), Flight Engineer ( Japan / JAXA ) (Soyuz TMA-02M)

Substitute team

Since Expedition 20, no official replacement team has been announced due to the permanent training for the six-person crew. Unofficially, the backup crews of the two Soyuz feeder spaceships TMA-21 and TMA-02M (see there) are considered substitute crews for Expedition 28. As a rule, these crews are deployed two missions later.

Mission history

On June 28, 2011, the ground station discovered a previously unknown piece of space junk that was dangerously close to the ISS. Since the advance warning time was too short to correct the orbit of the ISS as usual, the six space travelers went to the two Soyuz spacecraft for their safety. They had previously closed the hatches between the ISS modules and switched the ISS to unmanned operation. After the debris had passed the space station at a distance of 250 meters, the crew was able to board the ISS again.
