I like it, but +66 is Thailand already. It would probably get one of the available +87x or +88x codes. If they aren't just going to issue numbers from the home country.

I like it, but +66 is Thailand already. Maybe Thailand could be reassigned. Like when Mexico dropped out of +1 to become +52. Or maybe instead of +, we dial & to get off-planet.

SPICE is pretty awesome. I wish that more people in the aerospace industry were aware of, including people AT NASA. I work at a company contracting on NASA projects and a couple weeks ago I had to correct their code because they weren't accounting for the leap second offset between UTC and GPS correctly. When I asked why he wrote his own function instead of using SPICE he responded "what's SPICE?". Literally people i…

Need to bring back some of those brownbag lunch & learn events, starting with "SPICE up your clocks"! Except people might not be comfortable sitting in the same room these days

Delta T in this case is probably referring to the change between the minimum and maximum temperatures experienced on the surface of the moon. In other words, the delta between something getting really hot spending 14 days in direct sunlight with no convection to cool it down and then getting really cold spending 14 days in darkness. Delta T (for temperature) can also refer to the delta in temperature across an object…

Could a buffer (e.g. water) be used? Basically... radiate heat out of the buffer when it's cold and move heat from the device into the buffer when it's warm?

It depends on which layer you're asking about addressing. You can represent anything non-relatavistic on top of the Unix epoch, and it could be handled as simply as using alternate time zones. The big problems come from huge Earth assumptions about interval duration and interval sequencing being violated. A lunar day is 29.5 Earth days. Does the lunar calendar use solar days, and just have absurdly long weeks and yea…

Off earth you have a launch criterion and accumulated subjective seconds. That's your onboard time. There are no days, weeks, months, years. Just count the seconds and make sure everyone knows the epoch you started at. Now, let's suppose you have a permanent settled outpost on Luna. You still use accumulated seconds as your time basis, but for casual conversation, you can talk about any Earth time marking that makes…

There’s lots of comments about roaming charges and dialling codes here but despite using 4G/LTE I’m assuming this is a closed network - you won’t be able to call an astronaut without going through NASA.
