Ulf Dietrich Merbold ({{#invoke:IPA|main}}; born 20 June 1941) is a German physicist and astronaut who flew to space three times, becoming the first West German citizen in space and the first non-American to fly on a NASA spacecraft. Merbold flew on two Space Shuttle missions and on a Russian mission to the space station Mir, spending a total of 49 days in space.
Merbold's father was imprisoned in NKVD special camp Nr. 2 by the Red Army in 1945 and died there in 1948, and Merbold was brought up in the town of Greiz in East Germany by his mother and grandparents. As he was not allowed to attend university in East Germany, he left for West Berlin in 1960, planning to study physics there. After the Berlin Wall was built in 1961, he moved to Stuttgart, West Germany. In 1968, he graduated from the University of Stuttgart with a diploma in physics, and in 1976 he gained a doctorate with a dissertation about the effect of radiation on iron. He then joined the staff at the Max Planck Institute for Metals Research.
In 1977, Merbold successfully applied to the European Space Agency (ESA) to become one of their first astronauts. He started astronaut training with NASA in 1978. In 1983, Merbold flew to space for the first time as a payload specialist or science astronaut on the first Spacelab mission, STS-9, aboard the Space Shuttle Columbia. He performed experiments in materials science and on the effects of microgravity on humans. In 1989, Merbold was selected as payload specialist for the International Microgravity Laboratory-1 (IML-1) Spacelab mission STS-42, which launched in January 1992 on the Space Shuttle Discovery. Again, he mainly performed experiments in life sciences and materials science in microgravity. After ESA decided to cooperate with Russia, Merbold was chosen as one of the astronauts for the joint ESA–Russian Euromir missions and received training at the Russian Yuri Gagarin Cosmonaut Training Center. He flew to space for the third and last time in October 1994, spending a month working on experiments on the Mir space station.
Between his space flights, Merbold provided ground-based support for other ESA missions. For the German Spacelab mission Spacelab D-1, he served as backup astronaut and as crew interface coordinator. For the second German Spacelab mission D-2 in 1993, Merbold served as science coordinator. Merbold's responsibilities for ESA included work at the European Space Research and Technology Centre on the Columbus program and service as head of the German Aerospace Center's astronaut office. He continued working for ESA until his retirement in 2004.

Astronaut trainingEdit
In 1973, NASA and the European Space Research Organisation, a precursor organization of the European Space Agency (ESA),Template:Sfn agreed to build a scientific laboratory that would be carried on the Space Shuttle, then under development.Template:Sfn The memorandum of understanding contained the suggestion the first flight of Spacelab should have a European crew member on board.Template:Sfn The West German contribution to Spacelab was 53.3% of the cost; 52.6% of the work contracts were carried out by West German companies, including the main contractor ERNO.Template:Sfn
In March 1977, ESA issued an Announcement of Opportunity for future astronauts, and several thousand people applied.Template:Sfn Fifty-three of these underwent an interview and assessment process that started in September 1977, and considered their skills in science and engineering as well as their physical health.Template:Sfn Four of the applicants were chosen as ESA astronauts; these were Merbold, Italian Franco Malerba, Swiss Claude Nicollier and Dutch Wubbo Ockels.Template:Sfn The French candidate Jean-Loup Chrétien was not selected, angering the President of France. Chrétien participated in the Soviet-French Soyuz T-6 mission in June 1982, becoming the first West European in space.Template:Sfn In 1978, Merbold, Nicollier and Ockels went to Houston for NASA training at Johnson Space Center while Malerba stayed in Europe.Template:Sfn
NASA first discussed the concept of having payload specialists aboard spaceflights in 1972,Template:Sfn and payload specialists were first used on Spacelab's initial flight.Template:Sfn Payload specialists did not have to meet the strict NASA requirements for mission specialists. The first Spacelab mission had been planned for 1980 or 1981 but was postponed until 1983; Nicollier and Ockels took advantage of this delay to complete mission specialist training. Merbold did not meet NASA's medical requirements due to a ureter stone he had in 1959,Template:Sfn and he remained a payload specialist.Template:SfnTemplate:Sfn Rather than training with NASA, Merbold started flight training for instrument rating at a flight school at Cologne Bonn Airport and worked with several organizations to prepare experiments for Spacelab.Template:Sfn
In 1982, the crew for the first Spacelab flight was finalized, with Merbold as primary ESA payload specialist and Ockels as his backup. NASA chose Byron K. Lichtenberg and his backup Michael Lampton.Template:Sfn The payload specialists started their training at Marshall Space Flight Center in August 1978, and then traveled to laboratories in several countries, where they learned the background of the planned experiments and how to operate the experimental equipment.Template:Sfn The mission specialists were Owen Garriott and Robert A. Parker, and the flight crew John Young and Brewster Shaw.Template:Sfn In January 1982, the mission and payload specialists started training at Marshall Space Flight Center on a Spacelab simulator. Some of the training took place at the German Aerospace Center in Cologne and at Kennedy Space Center.Template:Sfn While Merbold was made very welcome at Marshall, many of the staff at Johnson Space Center were opposed to payload specialists, and Merbold felt like an intruder there.Template:Sfn Although payload specialists were not supposed to train on the Northrop T-38 Talon jet, Young took Merbold on a flight and allowed him to fly the plane.<ref name="merbold young">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
STS-9 Space Shuttle missionEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Merbold first flew to space on the STS-9 mission, which was also called Spacelab-1, aboard Space Shuttle Columbia.Template:Sfn The mission's launch was planned for 30 September 1983, but this was postponed because of issues with a communications satellite. A second launch date was set for 29 October 1983, but was again postponed after problems with the exhaust nozzle on the right solid rocket booster.Template:Sfn After repairs, the shuttle returned to the launch pad on 8 November 1983, and was launched from Kennedy Space Center Launch Complex 39A at 11:00Template:Nbspa.m. EST on 28 November 1983.Template:SfnTemplate:Sfn Merbold became the first non-US citizen to fly on a NASA space mission and also the first West German citizen in space.Template:Sfn<ref name="FR">Template:Cite news</ref> The mission was the first six-person spaceflight.Template:SfnTemplate:Sfn
During the mission, the shuttle crew worked in groups of three in 12-hour shifts, with a "red team" consisting of Young, Parker and Merbold, and a "blue team" with the other three astronauts.Template:Sfn The "red team" worked from 9:00Template:Nbspp.m. to 9:00Template:Nbspa.m. EST.Template:Sfn Young usually worked on the flight deck, and Merbold and Parker in the Spacelab.Template:Sfn Merbold and Young became good friends.Template:Sfn On the mission's first day, approximately three hours after takeoff and after the orbiter's payload bay doors had been opened, the crew attempted to open the hatch leading to Spacelab.Template:SfnTemplate:Sfn At first, Garriott and Merbold could not open the jammed hatch; the entire crew took turns trying to open it without applying significant force, which might damage the door. They opened the hatch after 15 minutes.Template:Sfn
The Spacelab mission included about 70 experiments,Template:Sfn many of which involved fluids and materials in a microgravity environment.Template:Sfn The astronauts were subjects of a study on the effects of the environment in orbit on humans;Template:Sfn these included experiments aiming to understand space adaptation syndrome, of which three of the four scientific crew members displayed some symptoms.Template:SfnTemplate:Sfn Following NASA policy, it was not made public which astronaut had developed space sickness.Template:Sfn Merbold later commented he had vomited twice but felt much better afterwards.Template:Sfn Merbold repaired a faulty mirror heating facility, allowing some materials science experiments to continue.Template:Sfn The mission's success in gathering results, and the crew's low consumption of energy and cryogenic fuel, led to a one-day mission extension from nine days to ten.Template:Sfn
On one of the last days in orbit, Young, Lichtenberg and Merbold took part in an international, televised press conference that included US president Ronald Reagan in Washington, DC, and the Chancellor of Germany Helmut Kohl, who was at a European economic summit meeting in Athens, Greece.Template:SfnTemplate:SfnTemplate:Sfn During the telecast, which Reagan described as "one heck of a conference call", Merbold gave a tour of Spacelab and showed Europe from space while mentioning {{#invoke:Lang|lang}} (the beauty of the Earth).Template:Sfn<ref name="wapo">Template:Cite news</ref> Merbold spoke to Kohl in German, and showed the shuttle's experiments to Kohl and Reagan, pointing out the possible importance of the materials-science experiments from Germany.<ref name="wapo" />
When the crew prepared for the return to Earth, around five hours before the planned landing, two of the five onboard computers and one of three inertial measurement units malfunctioned, and the return was delayed by several orbits.Template:Sfn Columbia landed at Edwards Air Force Base (AFB) at 6:47Template:Nbspp.m. EST on 8 December 1983.Template:Sfn Just before the landing, a leak of hydrazine fuel caused a fire in the aft section.Template:Sfn After the return to Earth, Merbold compared the experience of standing up and walking again to walking on a ship rolling in a storm.Template:Sfn The four scientific crew members spent the week after landing doing extensive physiological experiments, many of them comparing their post-flight responses to those in microgravity.Template:Sfn After landing, Merbold was enthusiastic about the mission and the post-flight experiments.Template:Sfn
Ground-based astronaut workEdit
In 1984, Ulf Merbold became the backup payload specialist for the Spacelab D-1 mission, which West Germany funded.Template:SfnTemplate:Sfn The mission, which was numbered STS-61-A, was carried out on the Space Shuttle Challenger from 30 October to 6 November 1985.Template:Sfn In ESA parlance, Merbold and the three other payload specialists—Germans Reinhard Furrer and Ernst Messerschmid and the Dutch Wubbo Ockels—were called "science astronauts" to distinguish them from "passengers" like Saudi prince Sultan bin Salman Al Saud and Utah senator Jake Garn, both of whom had also flown as payload specialists on the Space Shuttle.Template:Sfn During the Spacelab mission, Merbold acted as crew interface coordinator, working from the German Space Operations Center in Oberpfaffenhofen to support the astronauts on board while working with the scientists on the ground.Template:Sfn
From 1986, Merbold worked for ESA at the European Space Research and Technology Centre in Noordwijk, Netherlands, contributing to plans for what would become the Columbus module of the International Space Station (ISS).<ref name="ESA2004" /> In 1987, he became head of the German Aerospace Center's astronaut office, and in April–May 1993 he served as science coordinator for the second German Spacelab mission D-2 on STS-55.<ref name="ESA2004" />
STS-42 Space Shuttle missionEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
In June 1989, Ulf Merbold was chosen to train as payload specialist for the International Microgravity Laboratory (IML-1) Spacelab mission.Template:Sfn STS-42 was intended to launch in December 1990 on Columbia but was delayed several times. After first being reassigned to launch with Atlantis in December 1991,Template:Sfn it finally launched on the Space Shuttle Discovery on 22 January 1992, with a final one-hour delay to 9:52 a.m. EST caused by bad weather and issues with a hydrogen pump.Template:Sfn The change from Columbia to Discovery meant the mission had to be shortened, as Columbia had been capable of carrying extra hydrogen and oxygen tanks that could power the fuel cells.Template:Sfn Merbold was the first astronaut to represent reunified Germany.Template:Sfn The other payload specialist on board was astronaut Roberta Bondar, the first Canadian woman in space.Template:Sfn Originally, Sonny Carter was assigned as one of three mission specialists, he died in a plane crash on 5 April 1991, and was replaced by David C. Hilmers.Template:Sfn
The mission specialized in experiments in life sciences and materials science in microgravity.Template:Sfn IML-1 included ESA's Biorack module,Template:Sfn a biological research facility in which cells and small organisms could be exposed to weightlessness and cosmic radiation.Template:Sfn It was used for microgravity experiments on various biological samples including frog eggs, fruit flies, and Physarum polycephalum slime molds. Bacteria, fungi and shrimp eggs were exposed to cosmic rays.Template:Sfn Other experiments focused on the human response to weightlessness or crystal growth.Template:Sfn There were also ten Getaway Special canisters with experiments on board.Template:Sfn Like STS-9, the mission operated in two teams who worked 12-hour shifts: a "blue team" consisting of mission commander Ronald J. Grabe together with Stephen S. Oswald, payload commander Norman Thagard, and Bondar; and a "red team" of William F. Readdy, Hilmers, and Merbold.Template:Sfn Because the crew did not use as many consumables as planned, the mission was extended from seven days to eight, landing at Edwards AFB on 30 January 1992, at 8:07Template:Nbspa.m. PST.Template:Sfn
Euromir 94 missionEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} In November 1992, ESA decided to start cooperating with Russia on human spaceflight. The aim of this collaboration was to gain experience in long-duration spaceflights, which were not possible with NASA at the time,Template:Sfn and to prepare for the construction of the Columbus module of the ISS.<ref name="DLR">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="ESA1994">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> On 7 May 1993, Merbold and the Spanish astronaut Pedro Duque were chosen as candidates to serve as the ESA astronaut on the first Euromir mission, Euromir 94.Template:Sfn
Along with other potential Euromir 95 astronauts, German Thomas Reiter and Swedish Christer Fuglesang, in August 1993 Merbold and Duque began training at Yuri Gagarin Cosmonaut Training Center in Star City, Russia, after completing preliminary training at the European Astronaut Centre, Cologne.<ref name="ESA2004" />Template:Sfn On 30 May 1994, it was announced Merbold would be the primary astronaut and Duque would serve as his backup.Template:Sfn Equipment with a mass of Template:Convert for the mission was sent to Mir on the Progress M-24 transporter, which failed to dock and collided with Mir on 30 August 1994, successfully docking only under manual control from Mir on 2 September.Template:Sfn
Merbold launched with commander Aleksandr Viktorenko and flight engineer Yelena Kondakova on Soyuz TM-20 on 4 October 1994, 1:42 a.m. Moscow time.Template:Sfn Merbold became the second person to launch on both American and Russian spacecraftTemplate:Sfn after cosmonaut Sergei Krikalev, who had flown on Space Shuttle mission STS-60 in February 1994 after several Soviet and Russian spaceflights. During docking, the computer on board Soyuz TM-20 malfunctioned but Viktorenko managed to dock manually.Template:Sfn The cosmonauts then joined the existing Mir crew of Yuri Malenchenko, Talgat Musabayev and Valeri Polyakov,Template:Sfn expanding the crew to six people for 30 days.Template:Sfn
On board Mir, Merbold performed 23 life sciences experiments, 4 materials science experiments, and other experiments.<ref name="euromir">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> For one experiment designed to study the vestibular system, Merbold wore a helmet that recorded his motion and his eye movements.Template:Sfn On 11 October, a power loss disrupted some of these experimentsTemplate:Sfn but power was restored after the station was reoriented to point the solar array toward the Sun.<ref name="euromir" /> The ground team rescheduled Merbold's experiments but a malfunction of a Czech-built materials processing furnace caused five of them to be postponed until after Merbold's return to Earth.<ref name="euromir" /> None of the experiments were damaged by the power outage.Template:Sfn
Merbold's return flight with Malenchenko and Musabayev on Soyuz TM-19 was delayed by one day to experiment with the automated docking system that had failed on the Progress transporter.Template:Sfn The test was successful and on 4 November, Soyuz TM-19 de-orbited, carrying the three cosmonauts and Template:Convert of Merbold's samples from the biological experiments, with the remainder to return later on the Space Shuttle.<ref name="euromir" /> The STS-71 mission was also supposed to return a bag containing science videotapes created by Merbold but this bag was lost.Template:Sfn The landing of Soyuz TM-19 was rough; the cabin was blown off-course by Template:Convert and bounced after hitting the ground.Template:SfnTemplate:Sfn None of the crew were hurt during landing.Template:Sfn
During his three spaceflights—the most of any German national—Merbold has spent 49 days in space.<ref name="ESA_sts9">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
