THE GIANTS OF HEAT TRANSFER: DR. ROBERT DEISSLER, DR. SIMON OSTRACH, AND DR. ROBERT SIEGEL
The NASA Glenn Research Center established itself as a hub of heat transfer expertise early in its history, when it was a National Advisory Committee on Aeronautics (NACA) laboratory. Rooted in basic, instead of applied, research, a group of the lab’s heat transfer researchers developed new theories that would transform the body of knowledge. As Virginia Dawson explains in her history of the Center, Engines and Innovations, “A new theory was like a new piece of hardware, something on the shelf, ready if it was needed in the future.” Management was more comfortable with a new compressor or afterburner, but the value of theoretical contributions was also appreciated. The theoretical skills of these heat transfer experts made them world renown in their own right, and the application of their theories helped the Center to expand and excel in emerging fields like jet engines, nuclear propulsion, and space exploration.

Biography

Robert Deissler began his broad heat transfer career in 1947 at the NACA Aircraft Engine Research Laboratory, which would later become NASA Glenn. He gained early recognition in the field for a series of papers dealing with turbulent flow and heat transfer of variable-property fluids in pipes or tubes. He quickly advanced to chief of the Heat Transfer Branch. Deissler was recognized as a major contributor to the theory of turbulent-flow heat transfer, and he authored many papers and articles, as well as an authoritative text book, on the subject. In 1957 he received the Exceptional Service Award from the NACA for his contributions to the understanding of heat transfer problems associated with aircraft nuclear propulsion. Among his numerous other honors, Deissler received the Max Jakob Memorial Award in 1975 from the American Society of Mechanical Engineers (ASME) and American Institute for Chemical Engineering AICE for the prestigious achievement of distinguished service in the area of heat transfer. He was honored as an ASME fellow in 1977 and as an American Institute of Aeronautics and Astronautics (AIAA) fellow in 1982. He retired in 1994 and passed away on August 16, 2015.

      NASA’s OSIRIS-REx Mission Awarded Robert Goddard Memorial Trophy
      By NASA
      3 min read
      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s OSIRIS-REx team was selected as the winner of the National Space Club and Foundation’s 2024 Dr. Robert H. Goddard Memorial Trophy for their tremendous work on the first U.S. mission to bring an asteroid sample to Earth. The winning team  received the award at the 67th Annual Robert H. Goddard Memorial Dinner at the Washington Hilton Hotel on March 22, 2024.
      The sample return capsule from NASA’s OSIRIS-REx mission is seen shortly after touching down in the desert, Sunday, Sept. 24, 2023, at the Department of Defense’s Utah Test and Training Range. The sample was collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft. NASA/Keegan Barber The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) team includes NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Lockheed Martin in Littleton, Colorado; University of Arizona, Tucson and KinetX in Tempe, Arizona.
      The trophy is National Space Club’s highest honor and presented annually to the individual or group who has made a substantial contribution to U.S. leadership in astronautics or rocketry.
      “The OSIRIS-REx team’s successful delivery of the asteroid Bennu sample to Earth will enable important scientific discoveries for generations to come,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters in Washington. “I’m so pleased to see the mission team recognized with the Robert H. Goddard Memorial Trophy for their accomplishments.”
      Making U.S. History
      Following its launch in 2016, the OSIRIS-REx mission made U.S. space history when it became the first U.S. spacecraft to touch an asteroid and capture a sample on Oct. 20, 2020, and again when it successfully returned with the sample to Earth on Sept. 24, 2023.
      The sample, which is the largest asteroid sample ever delivered to Earth, is from the ancient asteroid Bennu and will give researchers worldwide a glimpse into the earliest days of our solar system, offering insights into planet formation and the origin of organics that led to life on Earth. Data collected by the spacecraft combined with future analysis of the Bennu sample will also aid our understanding of asteroids that can impact Earth.
      The OSIRIS-REx mission conducted unprecedented centimeter-scale mapping of Bennu, surpassing precision levels achieved for any other planetary body and setting three Guinness World Records for: smallest object orbited by a spacecraft, closest orbit of an asteroid and highest resolution satellite map of any planetary body.
      “The OSIRIS-REx mission rewrote U.S. space exploration history,” said Joe Vealencis, president, NSCF. “The data the spacecraft collected, plus all that we have yet to uncover from the sample it brought back, means scientists and engineers will be reaping the benefits of this mission for years to come.”
      The Mission Continues
      Following its successful sample return, the OSIRIS-REx spacecraft was renamed OSIRIS-APEX and will now enter an extended mission to visit and study near-Earth asteroid Apophis in 2029.
      OSIRIS-REx’s success was made possible by the unique contributions of over 1,000 individuals from government and mission partners like the science lead at the University of Arizona, the project team at NASA’s Goddard Space Flight Center, the curation team at NASA’s Johnson Space Center, spacecraft design, operations, and recovery by Lockheed Martin, guidance and navigation at KinetX, and the launch provider at United Launch Alliance.
      OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the Science Mission Directorate at NASA Headquarters in Washington.

      Glenn Research Center established itself as a hub of heat transfer expertise early in its history. Rooted in basic research, as opposed to applied, this group developed new theories that would transform the body of knowledge up to that point. Robert Deissler, Simon Ostrach, adn Robert Siegel are three of the most influential heat transfer researchers in center history. Their theoretical skills made them world-renown in their own right, and it was the application of their theories that would help the center expand and excel in emerging fields such as jet engines, nuclear propulsion, and space exploration. Both Deissler and Siegel wrote seminal text books on the subject. Ostrach is a pioneer in the fields of buoyancy-driven flows and microgravity science.
      Biography
      Robert Siegel began his career at the Laboratory in 1955. His first work was with the heat transfer group, investigating issues with nuclear aircraft propulsion. Later, he became head of the Analytical Heat Transfer Section. Siegel began investigating heat transfer for conditions in space, leading him to design the world’s first drop tower in 1957.
      Siegel is regarded internationally as an expert on heat transfer, thanks in part to his text book, “Thermal Radiation Heat Transfer,” which he coauthored with J.W. Howell. When Siegel set out to develop a course on heat transfer for the center, he was not able to find a suitable textbook. The course notes he developed grew into this text book, which was published in 1972. There have been five editions of the book, and it has been translated into several languages. It is still used widely as a graduate-level textbook.
      In 1970 Siegel was awarded the ASME Heat Transfer Memorial Award, which recognizes pioneers in the field of heat transfer, for his many significant contributions to the knowledge of boiling, radiation, convection, and conduction, including pioneering experiments under zero-gravity conditions. Siegel was elected as an ASME fellow in 1977 and an AIAA Fellow in 1991. In 1986 he was awarded NASA’s Exceptional Scientific Achievement Medal for his numerous important and wide-ranging contributions to the field of heat transfer, including some of the earliest work on zero-gravity boiling, radiation heat transfer in porous media, and transient natural convection heat transfer. In 1996 he was presented with the Max Jakob Award for his distinguished contributions in the field of heat transfer. He retired from NASA in 1999.
      Dr. Robert Siegel passed away in September 2017.
