Spur (lunar crater)

Spur is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin visited it in 1971, on the Apollo 15 mission, during EVA 2. Spur was designated Geology Station 7.

Spur is located on the north slope of Mons Hadley Delta, about 200 m above the plain to the north. It is east of the much larger St. George crater, and about 5 km south of the Apollo 15 landing site itself.

The astronauts found the "Genesis Rock", sample 15415, at Spur. The sample contains a large clast of anorthosite, and Dave Scott said "Guess what we just found! I think we found what we came for" as he examined the sample. They also found samples 15445 and 15455, so-called black and white breccias, which are thought to be impact melt breccia resulting from the Imrbrium basin impact event.

The crater was named by the astronauts, and the name was formally adopted by the IAU in 1973.

  • Typeface anatomy

    Typeface anatomy describes the graphic elements that make up printed letters in a typeface.

    The strokes of a letter are the lines that make it up. Strokes may be straight, as in k l v w x z, or curved, as in c o s. If straight, they may be horizontal, vertical, or diagonal; if curved, open or closed. Typographers also speak of an instroke, where one starts writing the letter, as at the top of a c f, and an outstroke, where the pen leaves off, as at the bottom of c e j k t y.

    Typefaces are born from the struggle between rules and results. Squeezing a square about 1% helps it look more like a square; to appear the same height as a square, a circle must be measurably taller. The two strokes in an X aren't the same thickness, nor are their parallel edges actually parallel; the vertical stems of a lowercase alphabet are thinner than those of its capitals; the ascender on a d isn't the same length as the descender on a p, and so on. For the rational mind, type design can be a maddening game of drawing things differently in order to make them appear the same.

    Spur route

    A spur route is a usually short road forming a branch from a longer, more important route (typically a major road, freeway, Interstate Highway, or motorway). A bypass or beltway is never considered a true spur route as it typically reconnects with another or the same major road. Both loops and spurs can be forms of special route.

    Canada

    Ontario

    In the province of Ontario, most spur routes are designated as A or B, such as Highway 17A, or 7B. A stands for "Alternate Route", and usually links a highway to a town's central core or main attraction, while B stands for "Business Route" or "Bypass", but are used when a main highway is routed around a town and away from its former alignment. The designation of "C" was used twice (Highway 3C and 40C), and is assumed to mean "Connector". Both highways have long since been retired and are now county roads. There was also one road with the D designation (Highway 8D, later the original Highway 102), and this may have stood for "Diversion", as it was along the first completed divided highway in Canada at the time (Cootes Drive in Hamilton).

    Arms

    by: Seabear

    You left your black gloves on my table
    You left your dying horse in the stable
    Thinking of a way to get you to stay
    And up I was to fight the wind and waves for you
    I?m an owl with giant eyes
    I?m the scarecrow in the skies
    The ultimate goal out facing the north
    I wanted to stay inside and look down below with you
    You never said then when I was in your arms
    That was the moment that you lost your charm
    [Incomprehensible]
    And the trees, they never grew any leaves
    Shake my arms, shake my head
    I fell asleep when you got well
    And I?m turning for the lights tonight
