"The Deep Space Atomic Clock is being readied for flight next year. 
Moving hardware from the laboratory to space meant conquering a number 
of technological challenges."

A number of really hard technological challenges. Aside from taking a 
bench full of gear and squeezing it down to a few liters.

Note the date on an earlier note:
"DSAC is scheduled for launch in mid-2016"
