Data type Browse/Download Description
Images OCAMS The OSIRIS-REx Camera Suite consists of MapCam, a medium field imager; PolyCam, a narrow-field imager; and SamCam, a wide-field camera for context images and recording the sampling event.
TAGCAMS The Touch and Go Camera System provides imaging to aid in navigation to and around Bennu, to aid in sample acquisition, and to confirm sample stowage.
Spectra OVIRS The OSIRIS-REx Visible and Infrared Spectrometer is a point spectrometer with a wavelength range of 0.4 to 4.3 microns.
OTES The OSIRIS-REx Thermal Emission Spectrometer is a compact, spot Fourier-transform infrared interferometric spectrometer measuring absolute flux of thermally emitted radiation from 5.5 to 50 microns.
Nuclear REXIS - not yet available The Regolith X-Ray Imaging Spectrometer measures solar X-ray-induced fluorescence from Bennu to map the distribution of elements across its surface.
Magnetometer N/A No magnetometer instrument on OSIRIS-REx
Dust N/A No dust detector on OSIRIS-REx
Altimetry OLA The OSIRIS-REx Laser Altimeter is a scanning LIDAR system providing measurement of spacecraft range to the target body.
Radio Science Radio Science The OSIRIS-REx radio science observations will provide the information necessary to make estimates of the gravity field, mass, and other physical characteristics of Bennu.
Ground Campaign Mt. Bigelow Groundbased Bennu Observations Photometric and lightcurve observations of Bennu in the ECAS photometric system.
