The first New Voyager Program probe swarm to enter the Alpha Centauri binary system did so with their sails deployed to collect every watt of energy they could from the two stars. Their course took them straight towards Cen A, the brightest star in the system, and they soon overloaded their ability to store the energy they collected. That was all part of their plan. They took all of that energy and pumped it into their communications lasers in one, final, broadcast aimed directly at the second probe swarm.
