Summary of changes in v2021.1

AtmNRLMSISE is an atmosphere model based on the NRL MSISE model. It is based on extensive flight data and includes sun effects. The model is available in FORTRAN and C from NASA's website and here we provide a new native MATLAB port. Our function has an easy to use interface that automatically incorporates the sun information and lets you input your spacecrafts ECI coordinates. You can also choose to use the original interface.

We provide a complete set of functions for planning lunar missions in the Missions module. The software includes landing control systems and trajectory optimization tools. The Spacecraft Control Toolbox provides you with a lot of ways to do things, so you can use your own creativity to perform analyses or design a mission.

Orbit Module

TrajectoryOptimization was formerly in the Sail module, but as it has a low-thrust demo it has been moved to Orbit. The Zermelo problem is a classic optimization problem with an analytical solution that is used as a test case.
