The Deployable Optical Receiver Array (DORA) is a 3U testbed for future communications and radio astronomy technology. It includes a pathfinder for widefield optical laser receivers and a low frequency radio spectrometer which aims to find the last radio quiet areas on earth in the meter wavelength bands.
The DORA project is a partnership between ASU’s Low Frequency Cosmology lab who led the mission and the Interplanetary Lab who built and operated the spacecraft. See the LoCo DORA page
