Observational astrophysics has frequently been driven by the desire for ever increasing angular resolution, which has resulted in larger and more expensive telescopes with time. However, telescopes with very small apertures can sometimes perform cosmological measurements as important as their larger siblings. In this talk, I will present several examples of small aperture, space-based experiments providing unique views of the large scale structure of the Universe.  I will discuss recent results from the Cosmic Infrared Background Experiment (CIBER) that has successfully measured the amplitude of the near-IR background fluctuations on arcminute scales, and recent work using the Long Range Reconnaissance Imager (LORRI) on New Horizons to measure the cosmic optical background.  Missions that look to the future of this field, including CIBER-2 SPHEREx, a mid-class NASA Explorer mission designed to probe the inflationary history of the Universe and the evolution of galaxies, will be discussed.
