Langley’s newly built Measurement Systems Laboratory will serve as the primary research and development location for six branches within the Research and Engineering Directorates. The ribbon cutting will take place in April 2022.

Astronaut Karen Nyberg,Expedition 36 flight engineer,performs a Space Linear Acceleration Mass Measurement Device (SLAMMD) Body Mass Measurement test in the U.S. Laboratory.

Ultrasonic Measurement System. Ultrasonic measurement system will enable simultaneous measurement of temperature, velocity and density fields through a grid of ultrasonic sensors. This method incorporates a theoretical approach and machine learning techniques to develop a physics-informed data-driven calibration and operation workflow. This allows at least ten times faster data processing times as well as potential capability of transient measurements and solid particle detection. The system can also be utilized for health monitoring. This measurement technique is in line with the “air-breathing propulsion” core competency of GRC. However it can also enables next generation space data processing with higher performance computing capable of operating in harsh deep space environments.

Engineers Marleen Sundgaard (left) and Pranay Mishra measure their test lander's "workspace" -- the terrain where scientists want to set InSight's instruments -- at NASA's Jet Propulsion Laboratory in Pasadena, California. Making sure each feature of the workspace on Mars is mimicked here on Earth allows for more reliable tests to be performed before actually setting down InSight's instruments. https://photojournal.jpl.nasa.gov/catalog/PIA22880

STS064-05-020 (9-20 Sept. 1994) --- Astronaut Mark C. Lee gets his height measured by astronaut Jerry M. Linenger as part of a daily in-flight routine supporting a medical Detailed Supplementary Objective (DSO). Astronaut Richard N. Richards, STS-64 mission commander, looks on in the background. This study was designed to collect information about back pain and height changes experienced by astronauts during flight. Crew members participating in this DSO are required to record height measurements and long back-pain symptoms daily. As an ongoing program, this DSO will gather data from 30 astronauts who spend more than eight consecutive days in space. Photo credit: NASA or National Aeronautics and Space Administration

Skylab's Body Mass Measurement chair, the facility of the Body Mass Measurement experiment (M172), is shown here in this 1970 photograph. The M172 experiment determined the body mass of each crew member and observed changes in body masses during flight. Knowledge of exact body mass variations throughout the flight in significantly aided in the correlation of other medical data obtained during the flight. Mass measurements under zero-gravity conditions were achieved by the application of Newton's second law (force equals mass times acceleration). The Marshall Space Flight Center had program management responsibility for the development of Skylab hardware and experiments.
