Love is often thought to involve a merging of identities or a sense that a romantic partner is part of oneself. Couples who report feeling more satisfied with their relationships also feel more interconnected. We hypothesized that Facebook profile photos would provide a novel way to tap into romantic partners’ merged identities. In a cross-sectional study (Study 1), a longitudinal study (Study 2), and a 14-day daily experience study (Study 3), we found that individuals who posted dyadic profile pictures on Facebook reported feeling more satisfied with their relationships and closer to their partners than individuals who did not. We also found that on days when people felt more satisfied in their relationship, they were more likely to share relationship-relevant information on Facebook. This study expands our knowledge of how online behavioral traces give us powerful insight into the satisfaction and closeness of important social bonds.

The OSIRIS-REx Camera Suite (OCAMS) will acquire images essential to collecting a sample from the surface of Bennu. During proximity operations, these images will document the presence of satellites and plumes, record spin state, enable an accurate model of the asteroid's shape, and identify any surface hazards. They will confirm the presence of sampleable regolith on the surface, observe the sampling event itself, and image the sample head in order to verify its readiness to be stowed. They will document Bennu's history as an example of early solar system material, as a microgravity body with a planetesimal size- scale, and as a carbonaceous object. OCAMS is fitted with three cameras. The MapCam will record color images of Bennu as a point source on approach to the asteroid in order to connect Bennu's ground-based point-source observational record to later higher-resolution surface spectral imaging. The SamCam will document the sample site before, during, and after it is disturbed by the sample mechanism. The PolyCam, using its focus mechanism, will observe the sample site at sub-centimeter resolutions, revealing surface texture and morphology. While their imaging requirements divide naturally between the three cameras, they preserve a strong degree of functional overlap. OCAMS and the other spacecraft instruments will allow the OSIRIS-REx mission to collect a sample from a microgravity body on the same visit during which it was first optically acquired from long range, a useful capability as humanity reaches out to explore near-Earth, Main-Belt and Jupiter Trojan asteroids.
