Sunshield Radiative Cooling Simulator (2D)

A 2D side-view companion: stack up to six low-emissivity sunshield layers between a sun-facing hot plate and a telescope, and watch the same closed-form radiation-network equations drive the temperature-per-layer profile down toward cryogenic optics-side temperatures.

ControlsThree preset buttons set the distance from the Sun (Mercury 0.39 AU, Earth/L2 1.01 AU, Mars 1.52 AU); a distance slider (0.3-5.2 AU) fine-tunes it; a shield-count slider (0-6 layers) and an emissivity slider (0.02-0.5) set the sunshield design. The 2D side view draws the hot plate, shield stack and telescope color-coded by temperature, plus a live stair-step chart of temperature across the stack.

Space observatories like JWST cannot use fans or coolant loops to fight the Sun — the only way to lose heat in vacuum is by radiating it away, and the only way to lose it slowly enough to matter is to interrupt that radiation with floating shields. This 2D side-view companion draws the same stack of sunshield layers between a sun-facing hot plate and a cold telescope module as a flat temperature-profile chart, driven by the identical closed-form steady-state radiation-network equations. Slide the shield count, the layer emissivity, or the distance from the Sun and watch the stair-step temperature drop across the stack — and the live hot-plate, cold-shield and attenuation readouts — respond exactly as the physics dictates.
