LIMESTONE, Maine — The small team at Brunswick-based bluShift Aerospace will come one step closer to their dream of reaching the Alpha Centauri star system when they launch the Stardust 1.0 rocket at Limestone’s former Loring Air Force base next week. The launch will mark two historic firsts — the first commercial launch of a rocket powered by bio-derived fuel in the world, and the first commercial rocket launch in Maine. The crew were on the Loring runway on Jan.
