Description

The Near Earth Object Surveyor mission will survey the sky at infrared wavelengths in order to detect and discover ~100,000 NEOs, with sizes down to 25 m. The mission survey cadence is designed to provide sufficient self-followup to constrain the orbits and sizes of all detected NEOs. However, additional characterization of physical properties such as albedo and spectral taxonomy will require observations at reflected-light wavelengths. In this talk, we will discuss the expected results from the planned survey cadence, the orbital arcs and quality for NEOs that will be detected, and the expected visible-band brightnesses of these objects as determined by the mission's Survey Simulator. We also will discuss the ground- and space-based followup resources that would be most useful for these additional characterization observations.
