Nasa will make an announcement about results obtained from their flying observatory regarding the Moon on Monday.

26 October 2020 at 3:09 pm #583292Peter GudgeonParticipantHaving just checked that website it refers to “teleconference at 12 p.m. EDT Monday, Oct. 26” ?
My understanding is that there is “12 o’clock midday” and “12 o’clock midnight”. Surely 12 p.m. would come 1 minute after 11:59 p.m. Similarly midday, coming 1 minute after 11:59 a.m. would either be 12 a.m. or even 0 p.m.
I believe that the NASA website is referring to their midday.

26 October 2020 at 4:38 pm #583294Daryl DobbsParticipantJust popped up on the BBC
Water on the Moon could sustain a lunar base https://www.bbc.co.uk/news/science-environment-54666328
Bit optimistic headline
26 October 2020 at 6:52 pm #583295Daryl DobbsParticipantApparently using Sofia they claim to have found 12 flow per cubic meter in Claviu, seems rather a lot of molecular water
26 October 2020 at 7:16 pm #583296Dr Paul LeylandParticipant00:00 is the first midnight of each day; 12:00 is noon; 24:00 is the second midnight of each day.
00:00, occurring before the sun reaches its highest point the sky (except at the geographic poles), is quite clearly ante meridiem and 24:00 is equally clearly post meridiem.
Yes, I am a pedant. Guilty as charged.
26 October 2020 at 7:30 pm #583297Nick JamesParticipantDon’t get me started on NASA’s “discovery of xxx” press conferences and their wonderful mixture of units. From the BBC article: ““The amount of water is roughly equivalent to a 12-ounce bottle of water in a cubic metre of lunar soil.” I suppose it is not as bad as saying a bath full of water in something the size of a house. Indeed, over half a pint of water in a cubic metre of soil does sound an awful lot though. My garden possibly had less than that at some point in the last summer! I suppose I should really look at the Nature papers rather than rely on second hand reports on the BBC but life is too short…
26 October 2020 at 7:42 pm #583298Ray EmeryParticipantToday’s teatime BBC “PM” programme began with an announcement that NASA had discovered even more water than on “the dark side of the Moon”. It got switched off before I threw the radio out of the back door…
26 October 2020 at 10:37 pm #583299Dr Paul LeylandParticipantYou reaction is understandable. Clavius is clearly not on the dark side of the moon because I have seen it for myself. Mare Moscoviense is on the dark side of the moon (*)
Anyway, there is no dark side of the moon really. As a matter of fact, it is all dark (+).
* In the same sense as Africa used to be the dark continent.
+ According to Pink Floyd. As the albedo is roughly the same as that of tarmac they make a good case IMO.
