The concept of space ultra long wavelength array

Due to the absorption and scattering in the Earth's ionosphere, sky radio emission at very long wavelength (ULW) region is inaccessible from the Earth ground. However, the potential scientific discoveries make it greatly attractive to open up this virgin spectral region. In this paper, we propose a space ultra long wavelength pathfinder mission to answer some of the key science questions and open ways to future comprehensive ULW study.
