A NASA spacecraft set to explore a metallic asteroid for the first time will launch in 2022, a year earlier than originally planned, and reach its destination in 2026, four years ahead of schedule, giving ground teams a shorter wait for the mission’s scientific payoff and shaving $100 million off the project’s total cost, officials said Wednesday.
