Time is really critical for a spacecraft.
If you get it wrong, you might fire your rocket engines at just the wrong time, your navigation errors could go huge and it could have catastrophic consequences.
Thanks to Albert Einstein, we understand space and time and relativity.
And time on the moon runs ever so slightly faster than time on Earth because the moon is smaller than the Earth.
And we are entering an era of lots and lots of uh spacecraft heading to the moon for missions.
Space agencies around the world are looking to explore the.
south pole of the moon and they want to work together.
And in order to do that, they have to agree on what time it is, because time is really critical for a spacecraft.
It tells you when you want to fire your rocket engines.
If you get it wrong, you might fire your rocket engines at just the wrong time.
Your navigation errors could go huge and it could have catastrophic consequences for landers that are trying to position themselves and land on the moon really accurately.
At the moment it's up to any spacecraft operator what time they want to use.
They might synchronize themselves to Earth time, they might use a different moon time, they might just use a mission elapsed time, some time that is synchronized to the day that they lifted off from Earth.
The concept of agreeing that there should be a standard time is something that everybody is in broad agreement with.
It makes sense here on Earth, it makes sense on the moon as well.
There were three different versions of time, how to measure it on the moon, that were proposed.
One has been discarded.
The other ones are essentially looking at the time in the center of the moon or the time on the lunar surface.
Because those two things can be slightly different.
And there's discussions ongoing, and we expect to see a resolution to which one gets picked later this year.
