An atomic clock that could transform deep-space travel has successfully completed its first test run in space. NASA’s Deep Space Atomic Clock, which launched on a satellite in June 2019, outperformed ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by ...

A group of physicists has announced one of the highest performance atomic clocks ever made. The instrument is said to measure time so precisely that it will only lose one second every 300 billion ...

Since the beginning of the space program, astronauts have dealt with the realities of spaceflight from microgravity in weak muscles and space radiation, to sleep deprivation and disorientation. Both ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

If you like the retro look of old Soviet space hardware, then this replica of the model 774H Soyuz digital clock by [David Whitty] might be the perfect accessory for your desk. Forgoing the original ...

The most precise clock ever flown in space may not inspire thrills, but it could be the key to safely sending people to Mars. The appropriately named Deep Space Atomic Clock was successfully activated ...
