Terahertz Space Instruments and Technologies
NASA-Jet Propulsion Laboratory, California Institute of Technology, 4800 Oak Grove Drive, Pasadena, CA 91109, USA
NASA’s Jet Propulsion Laboratory, which completed eighty years of its existence in 2016, builds spacecraft and instruments for NASA missions. Exploring the universe and our own planet Earth from the space has been the mission of NASA. Robotics missions such as Voyager, which continues to go beyond our solar system, missions to Mars and other planets, exploring the stars and galaxies for astrophysics missions, exploring and answering the question, “are we alone in this universe?” has been the driving force for NASA exploration since its inception.
Fundamental science questions drive the selection of NASA missions. We develop new technologies and innovative instruments to make measurements that can answer these science questions. In this presentation, we will present an overview of the state-of-the-art radar, spectrometers, radiometers, and other instruments that we are currently developing and layout the details of the science questions they will try to answer. Rapid progress in multiple fronts, such as commercial software for component and device modeling, low-loss circuits and interconnect technologies, cell phone technologies, and submicron scale lithographic techniques are making it possible for us to design and develop smart, low-power yet very powerful instruments that can even fit in a SmallSat or CubeSat. We will also discuss the challenges of the future generation instruments in addressing the needs for critical scientific applications.
