8. Thermal Emission Imaging System (THEMIS) 2-IN-1 CAMERA 1. Visible Imaging (VIS) –Visible-light images with 18 meters per pixel resolution. 2. Infrared Imaging (IR) –The entire planet will be mapped in the infrared at 100 meters per pixel resolution. NASA/JPL

9. It’s all about light – The Electromagnetic Spectrum The SUN radiates and creates different types of LIGHT!

24. THEMIS Visible Filters There are 10 IR Filters/bands BLUE GREENREDIR 1IR 2

25. What Does a filter do?

29. What filter would you use to take an image of Mars?

30. THEMIS RAW VIS IMAGE Each framelet is taken once per second. Each framelet is shifted with respect to the others because Mars rotates underneath the spacecraft. 18 km 19 framelets

31. NASA/JPL/MSSS How much of Mars is imaged in a THEMIS image?

32. What is a pixel? ___m 18
