Thursday's temperature check (procès-verbaux of 4-4)

Let’s take a moment to come down from our Ryan Seacrest high of yesterday.  Do you know why humanity’s future looks more like Star Wars and less like Star Trek?  Bureaucracy! It’s always been the bureaucracy.  Back in the old days when Episode IV was known as “Star Wars”, the mouth breathing empire drones worried how they could maintain control of planets (they called them “systems” after solar system, but we all understood what they meant) after the emperor disbanded the Imperial Senate. Pre-CGI Grand Moff Tarkin brushed concerns aside and was dead by the end of the movie.  Now that we know what’s in store for humanity, it should come as no surprise that this past Tuesday, the White House told NASA to come up with Moon Standard Time.  In something that Einstein figured out, but was too busy working on his script for a Star Wars fan fiction, time is different on the Moon.  And that’s not just because there’s no Wi-Fi causing life to lose all meaning.  Because there’s less gravity on the moon, time there moves a tad more quickly – 58.7 microseconds every day – compared with on Earth.  That’s a difference of almost 25 seconds over a century.  We can’t have that, my lunar-self needs those 25 seconds to battle the traffic between The Sea of Tranquility and the Montes Apenninus.  What part of my “Morning Mash Up” on Sirius/XM will I have to skip?  Anyway, the future of humanity is in brave hands as the White House’s “US Office of Science and Technology Policy (OSTP)” issued the four-page memo in the most bureaucratic language possible.  The most vexing part of the memo is that the abbreviation for Office of Science and Technology Policy makes sense, but the time-zone – Coordinated Lunar Time is abbreviated “LTC”.  That’s not the right order, but we’re expected to accept it!  No answers, only questions. 

So, while I’m trying to balance out my earthly leap-second with the speed of lunar time, I’m here for you.

Stay Safe!

(NASA)  A Colourful Moon

Image Credit & Copyright: Alain Paillou

The Moon is normally seen in subtle shades of grey. But small, measurable color differences have been greatly exaggerated in this mosaic of high-resolution images captured near the Moon's full phase, to construct a multicolored, central moonscape. The different colors are recognized to correspond to real differences in the mineral makeup of the lunar surface. Blue hues reveal titanium rich areas while more orange and purple colors show regions relatively poor in titanium and iron. The intriguing Sea of Vapors, or Mare Vaporum, is below center in the frame with the sweeping arc of the lunar Montes Apenninus (Apennine Mountains) above it. The dark floor of 83 kilometer diameter Archimedes crater within the Sea of Rains, or Mare Imbrium, is toward the top left. Near the gap at the top of the Apennine's arc is the Apollo 15 landing site. Calibrated by rock samples returned by the Apollo missions, similar multicolor images from spacecraft have been used to explore the Moon's global surface composition.

August 1971, Apollo 15 commander David Scott working with a drill in order to obtain core samples of the lunar underground. Apollo 15 Moonwalkers James Irwin and David Scott stayed 67 hours on the lunar surface of which almost 20 hours were spent walking the slopes of Montes Apenninus near Hadley Rille. They collected 77 kilograms of Moonrock & lunar samples. Note, that since their third EVA, David Scott wore his Bulova 88510 chronograph strapped over his left forearm. THe flat glass and the almond shaped pushers distinguish this Bulova moonwatch from the regular Omega Speedmaster chronograph which was issued to NASA astronauts. In October 2015, this Bulova chronograph with moondust-stained velcro strap was auctioned as the only privately-owned watch to be worn on the surface of the moon! (Photo: NASA)

Clouds and another headcold kept me indoors for a week, but the binox are back. Callisto, Ganymede, Europa, Jupiter; Saturn; waning gibbous Moon. Don't usually see the waning phases at night, because the Moon rises later and later -- and then later becomes very early -- but I caught this one near the horizon. Nice to see Grimaldi, Aristarchus and Oceanus Procellarum in bright daylight, and the opposite direction of shadow along the Montes Apenninus and Montes Caucasus. #iphoneastrophotography #lunarphotography #galileanmoons #callisto #ganymede #europa #jupiter #saturn https://www.instagram.com/p/CUTzL6Bgsu7/?utm_medium=tumblr

The intensity of moonlight depends on several factors.

The lunar phase is the main factor of brightness, but even

under a full moon, which is the brightest phase, it provides

very little light compared to the solar day which does not

allow, for example, to read small letters or to distinguish colors.

Apollo 11 (July 16–24, 1969) Commander Neil Armstrong and

lunar module pilot Buzz Aldrin formed the American crew that

landed the Apollo Lunar Module Eagle on July 20, 1969.

They landed in the Sea of Tranquility.
