About PELT:

Plume Ejecta Lunar Tools, PELT, is a visual simulation sponsored by Florida Space Institute (FSI) and developed by teams of Computer Science students from the University of Central Florida. PELT’s goal is to provide accurate predictions of the lunar ejecta caused by spacecraft landings. This ejecta causes erosion on the surface of the moon and launches particles from the landing site at high speeds. These particles can be incredibly damaging to anything in their path, especially since any amount of damage to structures can be critical due to the hostile environment of the moon. Being able to predict how the landing procedure of a lunar lander impacts the potential landing site is essential when the safety of structures built on the moon and the satellites orbiting around it have to be considered.

User Guide:

  • The CSV will reach max capacity at 2,147,483,647 characters. This means it can capture 250 particles for 24 hours or 1000 particles for 6 hours before maxing out.
  • When you hover the mouse over the Download CSV button, the simulation pauses. It can be resumed by pressing the play button. This is to ensure pause happens before download.
  • If you are able to load the full simulation from the website and lose internet during a long simulation, you can still pause/play, download the CSV, and you can refresh the simulation, just don’t refresh the webpage.
  • The landing site is located around Shackleton crater at the south pole of the moon. This is where the next landing mission will be in 2024.
  • The player camera only works when the play button is pressed because of Unity frame rate math.
  • Check the “Hardware Acceleration” box to run the simulation on your device’s graphics hardware for better performance.
  • Hardware acceleration may not be available in your browser or on older devices
