Space Foundation to Honor Inductees at 37th Space Symposium


COLORADO SPRINGS, Colo. ” Space Foundation, a nonprofit advocate organization founded in 1983 for the global space ecosystem, today announced that three innovative technologies developed for space will be inducted as the 2022 class into the organization's Space Technology Hall of Fame®. The induction ceremony will occur during the 37th Space Symposium, held April 4-7, 2022, at The Broadmoor in Colorado Springs.

The 2022 inductees are:

  • Beowulf Computing Cluster
  • Bubble Detector Technology
  • CubeSat Design Standard

Founded in 1988, the Space Technology Hall of Fame recognizes the life-changing technologies emerging from global space programs; honors the scientists, engineers, and innovators responsible; and communicates to the public the importance of these technologies as a return on investment in space exploration.

Remarking on the honorees, Space Foundation CEO Tom Zelibor said, The advanced efforts put forth by this year's inductees are outstanding examples of adapting space technology for the enhancement of our lives here on Earth. On behalf of the entire Space Foundation, congratulations and we welcome the opportunity to herald life-changing work such as theirs and see it honored in the Space Technology Hall of Fame.

2022 Space Technology Hall of Fame Inductees

Beowulf Computing Cluster

In the late 1980s, the United States was concerned about falling behind in super-computing technology. James Fisher, then head of the Earth and Space Sciences (ESS) group at NASA Goddard Space Flight Center, identified the contributing issues, assembled a team, and supplied the support, funding, and prototype systems to bring high-performance computing to fruition.

Thomas Sterling was then brought into the ESS group and came up with the original Beowulf concept, realizing that an open-source operating system might allow the group to cluster computers together, thereby achieving the best speeds at a substantially lower cost. NASA published the results, and the group followed by publishing a detailed account of how to build a Beowulf system. Companies adopted the technology and began to offer clustered systems, and by 1998, pre-configured Beowulf-type systems were available for purchase. Beowulf-style clusters are still in use today around the globe.

Bubble Detector Technology

Nuclear physicist Dr. Harry Ing devised the original concept for the Bubble Detector. He led the R&D effort to develop the technology while working as a research scientist at Chalk River Nuclear Laboratories of Atomic Energy of Canada Ltd. Once proven and the wide range of uses identified, the Canadian government sought to introduce the technology into the private sector.

In 1988, Dr. Ing formed BTI and created the Bubble Detector to identify and record levels of neutron radiation exposure to humans. The detector is a small vial worn by astronauts while in space, and the portability of the unit ensures that the readings are accurate.

The technology has flown on more than two dozen space missions. BTI continues to work with the Canadian Space Agency to provide detectors and further refine the technology supporting the International Space Station and other international space programs.

CubeSat Design Standard

  • Individuals: Bob Twiggs, Stanford University Space Systems Development Laboratory professor, retired; Jordi Puag-Suari, California Polytechnic State University professor, retired
  • Organizations:, part of California Polytechnic State University CubeSat Lab; Ames Research Center, NASA

In 1999, Bob Twiggs, then a professor at Stanford University, and Jordi Puag-Suari, a professor at California Polytechnic State University, created CubeSat as a teaching tool to hasten access and provide experience to satellite functionality for students. CubeSat, a miniaturized satellite conforming to strict design specifications, is used to develop skills necessary for the design, manufacture, and testing of small satellites intended for low Earth orbit and to perform scientific research functions.

Twiggs and Puag-Suari developed the basic CubeSat design that would become the worldwide standard, including the launching mechanism known as the P-POD. The one key element in the concept’s success ” the standardization of the P-POD ” made it simpler for universities and research groups to launch CubeSats. In addition, it gave launch providers confidence that the technology was proven to deploy safely, without risk to launch vehicles or other payloads., a continuation of the work done by Puag-Suari, is responsible for managing and updating the standards for CubeSats and is currently the only governing body for CubeSat technology. The first use of a CubeSat for a NASA science mission was in 2006 at Ames Research Center to study the effects of space on living organisms. The agency has continued to deploy CubeSats as a part of various space exploration missions.
