A demonstration of the Visual Thermo-fluid dynamic Analyzer for Systems and Components (VTASC) computer program designed to efficiently build flow network models for use in the GFSSP program.
An overview of the user subroutine including program structure, solution algorithm, solver-user subroutine interaction, data structure, indexing subroutines, utility subroutines, utility subroutines and functions, and compiling and linking. Code examples are provided and includes a demonstration (Tank Blowdown with Heat Transfer).
This is a training plan that is used on Orion IV&V for new members that we are wanting to share with other entities outside of NASA.
This package presents the CRMS identification of special Conjunction cases and the documented process for handling these special cases. The presentation is beneficial to anyone considering performing Conjunction Assessment by identifying and understanding the types of special cases that requires attention.

The successful launch of the Parker Solar Probe (PSP) on August 12, 2018 with a Delta IV rocket and Star-48BV third stage has placed the spacecraft on a 7-year trajectory to study the Sun. The goals of PSP are to better characterize our solar environment and advance our understanding of the Sun at 9.86 Rs. A total of 42 trajectory correction maneuvers are planned. This paper documents trajectory correction maneuver analysis performed just prior to launch until just past the first solar encounter. The pre-launch analysis culminated in two final design cycles which analyzed 24 reference trajectories.
