We present the CuRIOS project (*Cu*beSats for *R*apid *I*nfrared and *O*ptical *S*urveys), which is a constellation of CubeSats that monitors all-sky, all-the-time at ~1 minute cadence. CuRIOS is aimed at studying the death and afterlife of stars: white dwarfs, neutron stars, and black holes. Each CubeSat would have a roughly 10 deg x 10 deg field of view with ~3'' spatial resolution and a limiting magnitude of I=19 (vega) in 15 min with SNR=10. Hundreds of CubeSats would be required to fully tile the entire sky. The CuRIOS project is now possible thanks to demonstrated economies of scale that already deployed satellite constellations have demonstrated. Build costs may drop by 50x between the first few satellites and the later >20 satellites. We will present a conceptual design for CuRIOS and describe the CuRIOS survey, which will observe transient phenomena originating from black holes and neutron stars in the Milky Way and beyond.
