Sts-79-patch.png
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 E. Blaha (NASA-Mir-3) replacing Shannon W. Lucid (NASA-Mir-2) aboard the Mir Space Station. The lettering of their names either up or down denotes transport up to the Mir Space Station or return to Earth on STS-79. The patch is in the shape of the Space Shuttle's airlock hatch, symbolizing the gateway to international 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 Extravehicular Mobility Unit (EMU) which are 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.

STS-42 Mission Insignia

Designed by the crewmembers, the STS- 42 Intemational Microgravity Lab- 1 insignia depicts the orbiter with the Spacelab module aboard. The spacecraft is oriented in a quiescent, tail-to-Earth, gravity-gradient attitude to best support the various microgravity payloads and experiments. The international composition of the crew is depicted by symbols representing Canada and the European Space Agency. The number 42 is represented by six white stars --- four on one side of the orbiter and two on the other. The single gold star above Earth's horizon honors the memory of astronaut Manley L. (Sonny) Carter, who was killed earlier this year in a commuter plane crash. A crew spokesperson stated that Carter ...was our crewmate, colleague and friend. Blue letters set against white give the surnames of the five astronauts and two payload specialists for the flight.
