The Orbiting Carbon Observatory - 3 (OCO-3) is a NASA Earth-monitoring instrument, designed and built by the Jet Propulsion Laboratory (JPL) to perform space-based observation of variations of global carbon dioxide (CO2) by sampling its emission sources and gradients from the unique vantage point of the International Space Station (ISS). This paper describes the development and results of the end-to-end verification, validation, and calibration activities that were performed to meet OCO-3's science, functional, and performance requirements prior to launch. The pre-launch activities encompassed a suite of tests and analyses that were performed after instrument assembly and prior to launch vehicle integration to demonstrate launch and mission readiness in terms of ISS compatibility, ground-based instrument calibrations, flight dynamics, environmental integrity, and pointing knowledge and accuracy.

The current work assesses the physiological and psychological responses to the 360° emotional videos selected from Stanford virtual reality (VR) affective database [Li et al., 2017], presented using VR head-mounted display (HMD). Participants were asked to report valence and arousal level after watching each video. The electro-dermal activity (EDA) was recorded while watching the videos. The current pilot study shows no significant difference in skin-conductance response (SCR) between the high and low arousal experience. Similar trends were observed during high and low valence. The self-report pilot data on valence and arousal shows no statistically significant difference between Stanford VR affective responses and the corresponding Indian population psychological responses. Despite positive result of no-significant difference in self-report across cultures, we are limited to generalize the result because of small sample size.
