NASA JPL takes a first step toward a GPS for space.
- Spacecraft have no independent navigation systems onboard. They rely on navigation instructions sent from Earth, which can take about 40 minutes to reach them.
- The presence of an onboard atomic clock would radically streamline spacecraft navigation and is crucial to autonomous space exploration missions.
- A SpaceX Falcon Heavy rocket will take NASA's Deep Space Atomic Clock up for a year-long mission starting June 24, 2019.
"Bottom line: It's probably best to set your alarm for a specific time and get up then."
If you don't want to know anything about your death, consider this your spoiler warning.

- The second law of thermodynamics states that order always moves to disorder, which we experience as an arrow of time.

- While Einstein's general theory of relativity permits time travel, the means to achieve it remain improbable in nature.
