STS-79 was the fourth in a series of NASA docking missions to the
Russian Mir Space Station, leading up to the construction and operation
of the International Space Station (ISS). As the first flight of the
Spacehab Double Module, STS-79 encompassed research, test and evaluation
of ISS, as well as logistics resupply for the Mir Space Station.
STS-79 was also the first NASA-Mir American crew member exchange
mission, with John Blaha (NASA-Mir 3) replacing Shannon Lucid (NASA-Mir
2) aboard the Mir Space Station. The lettering of their names either
up or down denotes transport up to the Mir Station or return to Earth
on STS-79.
The STS-79 patch is in the shape of the Space Shuttle's airlock hatch,
symbolizing the gateway to internationa cooperation in space. The
patch illustrates the historic cooperation between the United States
and Russia in space. With the flags of Russia and the United States
as a backdrop, the handshake of EVA-suited crew members symbolizes
mission teamwork, not only of the crew members but also the teamwork
between both countries' space personnel in science, engineering, medicine,
and logistics.
