“Such a NASA array would electronically-link thousands of dipole antennas spread over a range of five to ten kms and combine their long wavelength signals in a way that would mimic the imaging resolution of one large kms-wide radio telescope.”
The far side lunar radio observatory would be delivered to crater such as the Tsiolkovsky crater by the planned heavy lift Space Launch System and deployed by rovers similar to the Mars Curiosity. The deployment and subsequent transfer of radio data could be handled either by a communications satellite or by the envisioned Deep Space Station NASA has contemplated deploying at the Earth/Moon L2 point above the lunar far side.
Such a radio observatory would be able to image stars as they were being created in the wake of the Big Bang when the universe was about 15 million to 80 million years old. It could also detect indications of magnetic fields surrounding exo solar planets, providing protection from cosmic radiation and solar flares. That in turn would indicate a greater possibility of life.
Aside from the obvious technical challenges, the project would take 15 years and cost billions of dollars to complete, a dubious proposition so long as NASA’s budget remains lean.
