iOrca Code Release

The iOrca outlier detection algorithm is based on the K-nearest neighbors approach. It calculates the distances across the dataset to determine if data points are near or far away from their set of neighbors. If a point has an unusually large distance to its neighbors, it is considered an outlier and of interest to the user....

Timeline Builder Assistant

Current human spaceflight requirements limit the number of hours a crewmember can be outside of the habitation unit to 8 hours in a 48-hour period, and 24 hours in a seven-day period. This time must be appropriately balanced to complete science, exploration, and maintenance tasks. Off-days can be used for site transit...
