Communicator with aliens

A group of ultralight spacecraft with a streamlined cone-shaped shape will reach the limits of the Solar System and the nearest star systems faster than previously launched spacecraft for space exploration. A minimalistic set of devices will make the spacecraft light, which will give an advantage over heavier models. For one group of five ultralight spacecraft, the next group can be sent, whose tasks, for the most part, will include relaying signals from the leading group. The tasks of such spacecrafts will include sending signals and receiving any possible space signals and relaying these signals to Earth.
