The Deep Space Atomic Clock (DSAC) is a miniaturized and stable mercury ion atomic clock that is as stable as a ground clock. [4] The technology could enable autonomous radio navigation for spacecraft's time-critical events such as orbit insertion or landing, promising new savings on mission operations costs. [3]
The Near Earth Network (NEN, formerly GN or Ground Network) provides orbital communications support for near-Earth orbiting customer platforms via various ground stations, operated by NASA and other space agencies. It uses a number of different dishes scattered around the globe.
They span the spectrum from old organizations with small budgets to mature national or regional enterprises such as the National Aeronautics and Space Administration (NASA) of the United States, the European Space Agency (ESA) which coordinates for more than 20 constituent countries, the Japan Aerospace Exploration Agency (JAXA), the Roscosmos ...
NASA wants to come up with an out-of-this-world way to keep track of time, putting the moon on its own souped-up clock. Because there's less gravity on the moon, time there moves a tad quicker ...
This scale allows for time comparisons between different clocks in the laboratory. These atomic time scales are generally referred to as TA(k) for laboratory k. [61] Coordinated Universal Time (UTC) is the result of comparing clocks in national laboratories around the world to International Atomic Time (TAI), then adding leap seconds as ...
The White House on Tuesday directed NASA to establish a unified standard of time for the moon and other celestial bodies, as the United States aims to set international norms in space amid a ...
International Atomic Time (abbreviated TAI, from its French name temps atomique international [1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [2] TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3]
In June 2015, NASA and National Nuclear Security Administration of the U.S. Department of Energy, which had been studying impact events on their own, signed an agreement to work in cooperation. [ 9 ] In January 2016, NASA officially announced the establishment of the Planetary Defense Coordination Office (PDCO), appointing Lindley Johnson to ...
