DME-A (również: Explorer 31) – amerykański satelita naukowy, wysłany w ramach programu Explorer, którego celem było badanie jonosfery. 15 stycznia 1971 roku próbowano nawiązać kontakt z satelitą, jednak bez powodzenia. Odtąd satelita został uznany za utracony.

Explorer 31, also called DME-A, was a NASA satellite launched as part of the Explorer program. Explorer 31 was launched on 29 November 1965 from Vandenberg Air Force Base, California, with a Thor-Agena launch vehicle. Explorer 31 was released along with the Canadian satellite Alouette 2. Explorer 31 was a small ionospheric observatory instrumented to make direct measurements of selected ionospheric parameters at the spacecraft. Since the spacecraft had no tape recorder, data could be observed at the spacecraft only when the spacecraft was in sight of the telemetry station and when commanded on. Experiments were operated either simultaneously or sequentially, as desired. The satellite was spin-stabilized with the spin axis perpendicular to the orbit plane. The spin rate and spin axis were controlled by an onboard magnetic torquing system. The attitude and spin rate information were observed by a sun sensor and a three-axis magnetometer. Satellite performance was satisfactory except for a partial power failure in May 1966, which reduced data acquisition time to about half the nominal amount. Some difficulties were encountered in obtaining attitude information that was necessary for the reduction of the experiment observations. On July 1, 1969, the satellite data observations were terminated with five of the seven experiments operating. Responsibility for standby monitoring of the satellite was given to the ESSA telemetry station at Boulder, Colorado, on July 8, 1969. During this standby operation, experiment data were collected only once on 1 October 1969, for 9 minutes from the electrostatic probe for use in studying a red arc event. On January 15, 1971, no response was received from a variety of satellite commands, and the satellite was abandoned.

El doble lanzamiento componía la misión ISIS-X, una misión cooperativa entre la NASA y el Panel de Investigación de Defensa Canadiense. ISIS significa International Satellites for Ionospheric Studies. DME tenía una órbita con un apogeo a un kilómetro más de altura que el apogeo de Alouette 2 (de unos 3000 km de altura), y con un perigeo un kilómetro más bajo (de unos 500 km de altura). DME fue construido para el centro de vuelo espacial Goddard de la NASA en Greenbelt, Maryland, por el Laboratorio de Física Aplicada de la . El satélite llevaba ocho experimentos de medición de la ionosfera, entre ellos un espectrómetro de masas. Medía 0,76 m de diámetro y 0,63 m de alto.
