GMAT

In GMAT R2025 and earlier versions, why we can't change the type of rocket engine and why we can't visualize the energy output of the source. There's so much limitations in GMAT and when downloading GMAT R2025, it keep resuming when it is half way in the download.

A lot of MAC are still running on Intel processors. I find very disappointing that this new version of GMAT doesn't propose at least a stable 2025 version for both configurations (Intel and M based proc), when we know that Mac were not supported in previous versions of GMAT...

Great product. Runs fine on Windows 10, but is poor on Windows 11. For example, many of the drop down menus are not large enough to show all of the selectable parameters (see the parameter list in the ReportFile menu).

This is an awesome Trajectory Design tool!!! Thanks NASA Team.

I am absolutely delighted with this product and I want to thank the outstanding NASA and subcontractor developer team. Sometimes people forget this kind quality comes at zero cost to users worldwide. If that is a fault (and it is not), I admit to being an educator now although with a NASA/JPL past. My students love NASA GMAT. My teaching benefits immensely from GMAT and OpenFrames speaks well to this generation of students. The notion to have GMAT developers even respond to criticism is incredible considering that extremely expensive products are far less consistently backed up these days, not to speak of other FOSS tools for orbital mechanics without any real support over the years. Of course, as an old Fortran cat, I hope that Copernicus as well can be released to the public. But for now, thanks for NASA GMAT!
