| Popis: | The SABER instrument on the TIMED satellite has produced an amazing record of temperature, minor constituents, and energetics in Earth’s mesosphere and lower thermosphere (MLT). The data record is now 21.5 years in length and the SABER instrument continues to operate with no apparent degradation in measurement quality over that time. In this paper we will examine observed long-term changes in the MLT, focusing on temperature and energetics. We will also discuss the needs and requirements for future observing systems to generate Geospace Data Records. These records are defined as a time series of measurements of sufficient length, consistency, and continuity to determine geospace variability and change. Long term geospace change is now recognized as a factor in the growing space economy due to the proliferation of space debris. Future observations of the MLT and geospace will need to be designed with much more attention to measurement accuracy and stability to determine the magnitude and rate of change more clearly and reliably. Economic and space policy decisions related to risk and mitigation of long-duration orbital debris will require clear and unequivocal measures of trends in geospace density and temperatures.
