🔴⏰ NIST physicists solved the four-body problem to determine #Mars time runs 477 microseconds faster per day than #Earth – accounting for weaker gravity, orbital velocity, and nearby planetary masses. The calculation enables #future real-time communications with Mars #astronauts and advances timekeeping systems across the #solarsystem.
