NASA's Roman Telescope Could Operate for 22 Years, Double Original Plan

In the silence between stars, a telescope exceeded what its builders dared to expect. NASA's Nancy Grace Roman Space Telescope, designed for a decade of cosmic inquiry, consumed only a fraction of its allocated fuel during its first orbital correction — a quiet act of mechanical grace that has extended its potential lifespan to at least 22 years. What engineers planned as a buffer became a gift, and what was budgeted as expenditure became runway. In the long human project of understanding the universe, Roman has been given more time to listen.
