NASA’s SOFIA Discovers Water on Sunlit Surface of Moon

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

SOFIA has detected water molecules (H2O) in Clavius Crater, one of the largest craters visible from Earth, located in the Moon’s southern hemisphere. Previous observations of the Moon’s surface detected some form of hydrogen, but were unable to distinguish between water and its close chemical relative, hydroxyl (OH). Data from this location reveal water in concentrations of 100 to 412 parts per million – roughly equivalent to a 12-ounce bottle of water – trapped in a cubic meter of soil spread across the lunar surface. The results are published in the latest issue of Nature Astronomy.

Well that is indeed somewhat surprising.

12 oz = 0.34 kg or thereabouts. I actually had to look it up. I do wish they’d use SI units.

The moon is made of the same stuff as earth is.

maybe comets and stuff bring some from time to time

Sort of. Not as highly fractionated or as dense.
All of which makes mining the Moon not all that useful.

> Data from this location reveal water in concentrations of 100 to 412 parts per million

That’s 0.01% to 0.04%. Not bad.

well it’s all quarks and electrons and that right

How can they MAGA if they start using evil SI units?

(actually I thought NASA did use SI these days?)

500 gigalitres/23.77m long and for singles matches, 8.23m wide. For doubles matches the court is 10.97m wide. x 1/4 acre.

I think rood should probably be Rod which would make more sense. But then….

The rod or perch or pole (sometimes also lug) is a surveyor’s tool and unit of length of various historical definitions, often between 3 and 8 meters. In modern US customary units it is defined as ​16 1⁄2 US survey feet, equal to exactly ​1⁄320 of a surveyor’s mile, or a quarter of a surveyor’s chain, and is approximately 5.0292 meters.

So back to the drawing board.

Note that:

A rood is also an obsolete British unit of linear measure between 16 1⁄2 and 24 feet (5.0–7.3 m). It is related to the German Rute and the Danish rode. The original OED of 1914 said this sense was “now only in local use, and varying from 6 to 8 yards” (or 18 to 24 ft, “Rood”, II.7).

I make it about 1.139E-9.

(Assuming 1 Standard Sydharb, a doubles tennis court, and a mid-range rood)

Morning all. Just got here.
A rood is
a measure of land area equal to a quarter of an acre (40 square perches, approximately 0.1012 hectare).
I’m confused because this is a perch (& it’s not square)

i was giving you the benefit of the doubt that you wouldn’t be using an obsolete unit. I see I have to go back to the drawing board now and reappraise my appraisal of you!!!

You need a rod to catch a perch?

NASA finds liquid water on the Moon, raising hopes for exploration and habitation

https://www.abc.net.au/news/science/2020-10-27/water-molecules-discovered-on-moon-using-nasa-flying-telescope/12806148

One would think that water on the moon in sunlit areas would evaporate.

Question.

Why doesn’t the water in sunlit areas evaporate ?

From memory the Moon has daylight for 14 days in a row as it orbits the Earth. Perhaps such long nights allow water to stay frozen for their corresponding days.

I wonder how many water molecules are in space and whether the moon picks them up as it moves through space?

The researchers think it’s trapped inside glass beads.
