In the balmy late summer of 1924, people across the world prepared to receive the first messages from the intelligent alien civilization that was assumed to inhabit Mars. To tune in to these Martian communications, the U.S. military imposed a period of radio silence on the nation that spanned 36 hours between August 21 and 23, coinciding with an unusually close pass between Mars and Earth in their orbits around the Sun.

The SKA-Low team built a prototype instrument called EDA2 and ran some tests, finding over 112,000 signals from 1,506 different Starlink satellites, significantly stronger than target signals.
