Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Artifact Description
The Space Station currently is being designed to maximize crew safety through fault tolerance, safehaven provisions, and crew delivery and return using the Space Transportation System (STS). Studies have identified the need for assured crew return capability through a space-based "lifeboat" that is always available for use in contingencies encompassing (1) medical emergencies, (2) Space Station failures, and (3) interruption of STS services. This paper reviews major mission, operational, and system requirements and the process for evaluating a range of practical vehicle and operational options. It describes flight and ground system design concepts and the major trade studies being performed to select the best end-to-end system that will provide a basis for design and development. Flight vehicles include capsules with ballistic and low lift/drag characteristics and lifting body aerodynamic-shaped designs. Ground systems emphasize the use of existing resources.
