Creating a Lunar Time Zone: Positioning, Navigation & Timing (PNT) | UNOOSA

What time is it on the Moon? How do we prevent astronauts from getting lost? Can we make lunar landings safer?

By 2040, up to 1,000 people could be living on the Moon. Time moves 56 microseconds a day faster on the Moon. The sun can be up for 14 days at a time, and there are mountains that never experience nights. Thus, the international community needs a common, Moon-tailored way of keeping track of time. As humanity prepares for long-term lunar missions and settlements a reliable navigation and communication system will also be indispensable.

In this video, Dr. Javier Ventura-Traveset—Head of the Navigation Science Office and of European Space Agency Lunar PNT Coordination explains:

🕰️ Why defining a "Moon Time" is critical for future missions

📡 How lunar positioning, navigation, and timing (PNT) systems—like the European Space Agency’s Moonlight—will transform exploration  

🌍 How UNOOSA and the International Committee on Global Navigation Satellite Systems (GNSS) (ICG) are ensuring global cooperation on lunar navigation
