The Triana spacecraft carries 3 basic instruments: EPIC (Earth Polychromatic Imaging Camera, a 10-wavelength spectroradiometer), NISTAR (NIST Active Radiometer, a 3-channel cavity radiometer for sunlit-Earth energy emission), and Plasma-Mag (a Faraday cup and magnetometer for space weather observations). A drawing of the spacecraft and instruments is shown in Figure 8.
In addition to the instruments, Figure 8 shows the extended solar panels, high gain antenna (flat gray square), and the magnetometer boom. EPIC is shown with its "open-once" cover in the open position. NISTAR is mounted to its right showing the 3 cavity radiometer openings and reference diode. The solar wind analyzer (Faraday cup) is shown mounted on the sun-side of the spacecraft.
