Shields-1, NORAD ID 43850, has been operating in polar low earth orbit since December 2018 at 85 degrees inclination and an initial altitude of 500 kilometers, beginning in solar minimum activity. It launched with the NASA CubeSat Launch Initiative (CSLI) ELaNaXIX mission. Shields-1 has 8 Teledyne dosimeters on board behind different shielding thicknesses. It is a technology demonstration of an atomic number (Z)-grade shielded electronics enclosure, 3 Z-grade shielding samples baselined with 4 aluminum samples having dosimeters behind each sample and inside the electronics enclosure. In addition to the technology demonstration, Shields-1 has been providing scientific dosimetry of energetic particles in the polar low earth orbit space radiation environment.
