Yeah -- delays happen. The DSAC is part of the US Air Force STP-2 program. STP-2 launch was awarded to SpaceX in December, 2012. But the Falcon Heavy only completed it's first launch earlier this week, and instead of sending a customer payload they send a Tesla to past the orbit of Mars.
Correcting my earlier post, the new launch date for STP-2 appears to be "no earlier than" June, 2018. I'm relying on this source for launch estimates: https://spaceflightnow.com/launch-schedule/ -- Bill Byrom N5BB On Fri, Feb 9, 2018, at 7:54 AM, jimlux wrote: > On 2/8/18 8:55 PM, Bill Byrom wrote: > > After the successful Falcon Heavy launch earlier this week, it appears that > > the Deep Space Atomic Clock (DSAC) is now scheduled to go up in June 2018 > > on a Falcon Heavy carrying the US Air Force STP-2 test payloads. > > https://www.nasa.gov/feature/goddard/2018/nasa-tests-atomic-clock-for-deep-space-navigation > > > > For a fun video about this project suitable for non-time-nuts, see: > > https://www.nasa.gov/mission_pages/tdm/clock/sammy-the-second.html > > > > "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.
