[time-nuts] Deep Space Atomic Clock -- mission complete

[Keith E. Brandt, MD, MPH]

Time has run out for a NASA atomic clock experiment in space.

JPL said it shut down the Deep Space Atomic Clock last month after 
running for more than double its planned one-year lifetime. The atomic 
clock, a payload on the Orbital Test Bed spacecraft launched on the 
STP-2 mission in June 2019, demonstrated the accuracy in timing needed 
to use it for deep space navigation. [NASA/JPL]
