Alastair Westgarth, formerly the CEO of wireless antennae company Quintel, will be the CEO of Project Loon. Westgarth is replacing former satellite exec Tom Moore, who had only joined in August 2016.
Project Loon, which was unveiled in 2013, is an ambitious plan to connect the world by delivering the internet to rural areas from high-altitude balloons.
Earlier in 2017, Project Loon showed off big upgrades to the balloons, which now use artificial intelligence to "cluster" and more efficiently beam internet back to Earth.
Moore's hiring was intended to reflect a path towards commercialization for Project Loon, which has only seen limited deployments in countries including Sri Lanka since its unveiling.
X, previously known as Google X, tells Bloomberg that Moore will be staying on at the labs to pursue different projects. Moore had himself replaced Mike Cassidy, the project's leader since 2012, who stayed on at X to do different projects.
Alphabet did not immediately respond to a request for comment.
