Memorial plaque to Dr. Reinhard Furrer, at his former residence, Brunnenstraße 135, Berlin

Key Information

Reinhard Alfred Furrer (25 November 1940 – 9 September 1995) was a German physicist and astronaut.

Furrer was born in Wörgl, Ostmark (now Austria). After the end of World War II, his father was expelled from Austria. The family found a new home in Kempten im Allgäu, Bavaria. Furrer stayed there until he joined the University of Kiel to study physics. He later transferred to the Free University of Berlin, where he received a diploma in 1969, and a doctorate in 1972. During his time as a student in Berlin, he was involved in the building of the 145-metre-long (476 ft) "Tunnel 57" below the Berlin Wall, which was the escape route of 57 people from East Berlin to the West.

In 1974 he became assistant professor in Stuttgart and in 1979 qualified for full professorship. He spent time during 1980–1981 at the University of Chicago and during 1981 at the Argonne National Laboratory in Chicago, USA.

In 1977 Furrer applied for selection as an astronaut for the first Spacelab mission. He made it into the final round of candidates, although Ulf Merbold was finally selected. In 1982, the astronauts for the first German Spacelab mission were selected from the finalists for the first mission, and Furrer was one of the two chosen. He was a payload specialist on STS-61-A (D1), which was launched on 30 October 1985. The other payload specialists on the flight were Ernst Messerschmid and Wubbo Ockels (Netherlands).

Furrer wore the Sinn (watchmaker) model 140 S on his wrist during the STS-61-A mission in 1985

After his spaceflight he became a professor in 1987 as well as the Director of the Institute of Space Sciences at the Free University of Berlin.

Furrer was an avid pilot. He earned his pilot license in 1974, doing several long-distance trips with one engine planes - including a flight over the inland ice of Greenland in 1979 and a solo flight from Germany to Quito, Ecuador in 1981. His love for planes finally cost him his life, as he died in a plane crash after a flight show on the Johannisthal Air Field (Berlin). He was a passenger of pilot Gerd Kahdemann in a historic Bf 108 when the plane crashed shortly after 6:00 p.m. after performing a roll at low altitude. Both Kahdemann and Furrer were killed instantly.

[edit]

From the files of the GDR State Security Service:[citation needed] Concerning FURRER it is known that, as a member of the Arbeitsgemeinschaft 13 August e.V. Association (supporting association of the Checkpoint Charlie Museum), he was a close personal friend of the chairman of the anti communism organisation and former head of the "Action Group against Inhumanity" Rainer Hildebrandt. Besides his usual code name "Kurt Jacob" he was also known under the aliases "Reinhard", "Jens", "Heino", "Nikolai" and "Bartmann"... A permanent exhibition, dedicated to Furrer was opened in the Checkpoint Charlie Museum.

He assumed leadership of the newly founded institute, where he directed research efforts in space sciences following his experience as an astronaut on the Spacelab D1 mission. Through this role, Furrer established a prominent position within the German space research community, contributing to the advancement of space-related physics and institutional development in the field.

Astronaut selection and training

Application and selection process

Reinhard Furrer first applied in 1977 for selection as a payload specialist for the inaugural Spacelab mission. He advanced to the final round of candidates but was not selected, as Ulf Merbold was chosen instead. He applied again in 1982 to the DFVLR (now the DLR) for the Spacelab D1 mission. Furrer was selected as one of two payload specialists, having outcompeted 699 other applicants.

Preparation for spaceflight

Reinhard Furrer's preparation for spaceflight as a payload specialist on the Spacelab D1 mission began in 1983, when his training as a scientific astronaut commenced alongside Ulf Merbold, Ernst Messerschmid and Wubbo Ockels. The initial training phase was comprehensive, requiring Furrer—whose background was in physics—to intensively familiarize himself with medical topics essential for spaceflight operations. This included acquiring practical medical skills such as inserting needles and measuring blood pressure. The two-year preparation equipped him to manage the mission's demanding scientific requirements, particularly the high-density experiment workload that permitted minimal margin for error.

Spacelab D1 mission

Mission overview and crew

The Spacelab D1 mission, designated STS-61-A, launched on October 30, 1985, at 12:00:00 p.m. EST aboard the Space Shuttle Challenger from Kennedy Space Center's Launch Pad 39A. It concluded with a landing on November 6, 1985, at 9:44:53 a.m. PST on Runway 17 at Edwards Air Force Base, California, for a total mission duration of 7 days, 0 hours, 44 minutes, and 51 seconds. This flight represented the first German-dedicated Spacelab mission (Deutschland 1), largely financed and operated by West Germany, and marked the largest crew of eight ever carried aboard a single spacecraft from launch to landing. Scientific research and experiment operations for Spacelab D1 were controlled directly from the German Space Operations Center (GSOC) at Oberpfaffenhofen, near Munich, while NASA retained overall responsibility for Shuttle operations and safety. The crew comprised five American NASA astronauts and three European payload specialists. Commander Henry W. Hartsfield, Jr., led the mission, with Steven R. Nagel as pilot, and James F. Buchli, Guion S. Bluford, Jr., and Bonnie J. Dunbar serving as mission specialists. The payload specialists were Reinhard Furrer and Ernst Messerschmid from Germany, along with Wubbo J. Ockels from the Netherlands representing the European Space Agency.

Role and scientific contributions

Reinhard Furrer served as a payload specialist on the STS-61-A mission, known as Spacelab D-1, which was a German-funded scientific flight aboard Space Shuttle Challenger. As a payload specialist on the Blue Team, he worked alongside fellow German payload specialist Ernst Messerschmid and ESA payload specialist Wubbo Ockels to operate the experiments in the Spacelab module during the seven-day mission. The payload crew conducted operations on a 24-hour basis through alternating shifts to maximize scientific productivity. Furrer and Messerschmid investigated the effects of microgravity on the processing of materials and on the human body. The mission performed 75 scientific experiments, with a strong emphasis on materials science—an area of established German expertise—including solidification experiments, single crystal growth, composites, and fluid physics phenomena such as Marangoni convection, diffusion, and capillarity. Additional experiments addressed biological studies on cell functions, developmental processes, and plant gravity perception, as well as medical and physiological research into human vestibular adaptation, gravitational perception, and speed-time interactions in space. The payload specialists utilized facilities such as the Werkstofflabor for materials processing, the Vestibular Sled for orientation and balance studies, and the Biorack for biological work. These activities represented the most comprehensive series of microgravity experiments conducted to date in materials processing and related human functions, yielding data expected to require years of analysis and contributing significantly to knowledge of space-based phenomena. Furrer's physics background in atomic, solid state, chemical, and biophysics aligned closely with the mission's focus on fundamental microgravity effects.

Post-mission career

His enthusiasm for flying ended tragically when he died as a passenger in a plane crash in 1995.

Long-distance flights

Reinhard Furrer was an avid private pilot who obtained his first pilot's license in 1974 and undertook numerous long-distance flights in single-engine sports aircraft. His aviation pursuits included notable trips such as flights over Greenland’s ice sheet and a demanding solo journey from Germany to Quito, Ecuador. In 1981, Furrer completed a solo transatlantic and transcontinental flight to Ecuador, crossing thousands of kilometers of open ocean under visual flight rules. The route took him over Iceland, the largely uninhabitable ice cap of Greenland, the lakes and forests of Canada, along the St. Lawrence River, and through towering equatorial clouds. The entire flight spanned 76 hours, during which he continuously recorded his impressions, observations of natural forces, and personal feelings on a tape recorder amid complete solitude.

Death and legacy

1995 plane crash

On 9 September 1995, Reinhard Furrer died at the age of 54 in a plane crash during a flight demonstration at Johannisthal Airfield in Berlin. He was traveling as a passenger in a historic Messerschmitt Bf 108D-1 Taifun aircraft, registration D-EFPT, which was piloted by Gerd Kahdemann. The crash took place at approximately 18:15 while the aircraft was performing an aerobatic display as part of an air show. During a barrel roll maneuver—which is not permitted for this aircraft type—part of the wing broke off, leading to loss of control and the plane crashing. Both Furrer and Kahdemann were killed in the accident.
