Question: Which space station did Austrian Franz Viehböck and Germany's Klaus-Dietrich Flade both visit for a week in the early 1990s?

Context paragraphs:
Klaus-Dietrich Flade: Klaus-Dietrich Flade (born August 23, 1952) is a German pilot and former German Aerospace Center astronaut who visited the Mir space station in 1992 aboard the Soyuz TM-14 mission, returning to Earth a week later aboard Soyuz TM-13.

Extended Duration Orbiter: The Extended Duration Orbiter (EDO) program was a project by NASA to prepare for long-term (months) microgravity research aboard Space Station Freedom, which later evolved into the International Space Station.  Scientists and NASA needed practical experience in managing progressively longer times for their experiments.  The original space shuttle configuration usually provided a week to ten days of spaceflight.  Several research projects and hardware components were part of the project, of which the EDO-pallet was one of the most visible, contracted by Rockwell International.

Elizabethkingia miricola: Elizabethkingia miricola is a species of bacterium isolated from condensation water in Space Station Mir, related to "Elizabethkingia anophelis", the cause of the 2016 outbreak of "Elizabethkingia anophelis" human infections in Wisconsin that began in early November 2015.  The genus name "Elizabethkingia" honors former United States Centers for Disease Control (CDC) microbiologist Elizabeth O. King, and the specific epithet is derived from combining the Russian name of the space station from which the bacterium was isolated, "Mir" meaning "peace," and the Latin ""incola"" meaning "inhabitant," yielding "miricola", "inhabitant of the Mir space station."

Salyut 6: Salyut 6 (Russian: Салют-6 ; lit.  Salute 6), DOS-5, was a Soviet orbital space station, the eighth flown as part of the Salyut programme.  Launched on 29 September 1977 by a Proton rocket, the station was the first of the 'second-generation' type of space station.  Salyut 6 possessed several revolutionary advances over the earlier Soviet space stations, which it nevertheless resembled in overall design.  These included the addition of a second docking port, a new main propulsion system and the station's primary scientific instrument, the BST-1M multispectral telescope.  The addition of the second docking port made crew handovers and station resupply by unmanned Progress freighters possible for the first time.  The early Salyut stations had no means of resupply or removing accumulated garbage (aside from the limited amount that cosmonauts could carry in their Soyuz spacecraft), nor could the propulsion system be refueled once it exhausted its propellant supply.  Consequently, once the consumables launched with the station were used up, its mission had to be concluded and as a result, manned missions had a maximum duration of three months.  Progress spacecraft could now bring fresh supplies and propellant and also be used to dispose of waste, which was then destroyed once the spacecraft was deorbited.

Anatoli Ivanishin: Anatoli Alekseyevich Ivanishin (Russian: Анатолий Алексеевич Иванишин ; born 15 January 1969 in Irkutsk) is a Russian cosmonaut.  His first visit to space was to the International Space Station on board the Soyuz TMA-22 spacecraft as an Expedition 29 / Expedition 30 crew member, launching in November 2011 and returning in April 2012.  Ivanishin was the Commander of the International Space Station for Expedition 49.

Salyut 5: Salyut 5 (Russian: Салют-5 meaning "Salute 5"), also known as OPS-3, was a Soviet space station.  Launched in 1976 as part of the Salyut programme, it was the third and last Almaz space station to be launched for the Soviet military.  Two Soyuz missions visited the station, each manned by two cosmonauts.  A third Soyuz mission attempted to visit the station, but failed to dock, whilst a fourth mission was planned but never launched.

International Space Station program: The International Space Station program is tied together by a complex set of legal, political and financial agreements between the fifteen nations involved in the project, governing ownership of the various components, rights to crewing and utilization, and responsibilities for crew rotation and station resupply.  These agreements tie together the five space agencies and their respective International Space Station Programs and govern how they interact with each other on a daily basis to maintain station operations, from traffic control of spacecraft to and from the station, to utilization of space and crew time.  In spring 2010, the International Space Station Program Managers from each of the five partner agencies were presented with Aviation Week's Laureate Award in the Space category, and NASA's International Space Station Program was awarded the 2009 Collier Trophy.

Jeffrey Manber: Jeffrey Manber is regarded as one of the pioneering commercial space entrepreneurs.  As CEO of NanoRacks, from 2009, Manber has steered the growth of the first company to own and market its own hardware and services on board the International Space Station.  Manber has been involved in several of the key breakthrough commercial space projects, principally those revolving around the commercialization of space assets as well as the integration of the Russian space industry into major space programs, including that of the International Space Station.  Manber is believed to be the only American to be an official part of the Russian space corporation, RSC Energia, during their privatization period of the 1990s.

Franz Viehböck: Franz Artur Viehböck (born August 24, 1960 in Vienna) is an Austrian electrical engineer, and was Austria's first cosmonaut.  He was titulated "„Austronaut“" by his country's media.  He visited the Mir space station in 1991 aboard Soyuz TM-13, returning aboard Soyuz TM-12 after spending just over a week in space.

STS-123: STS-123 was a Space Shuttle mission to the International Space Station (ISS) which was flown by Space Shuttle "Endeavour".  STS-123 was the 1J/A ISS assembly mission.  The original launch target date was 14 February 2008 but after the delay of STS-122, the shuttle was launched on 11 March 2008.  It was the twenty-fifth shuttle mission to visit the ISS, and delivered the first module of the Japanese laboratory, Japanese Experiment Module (Kibō), and the Canadian Special Purpose Dexterous Manipulator, (SPDM) "Dextre" robotics system to the station.  The mission duration was 15 days and 18 hours, and it was the first mission to fully utilize the Station-to-Shuttle Power Transfer System (SSPTS), allowing space station power to augment the shuttle power systems.  The mission set a record for a shuttle's longest stay at the ISS.
