Tom Moore, a satellite veteran brought in to lead Google's Project Loon unit, has stepped down after about six months. Alastair Westgarth, who headed wireless antenna company Quintel, is taking the spot.
The transition comes after the company scaled back an ambitious attempt to build a global communications service by circling the earth with high-altitude balloons. X, the research division of Google parent Alphabet Inc., recruited Moore in August after the unit's earlier leader, Mike Cassidy, stepped down. Moore started in mid-September.
