Your tax dollars at work, NASA incredible Moon division: Full rotation

July 19, 2018

NASA posted this back in 2013 — but a lot of people missed it. It’s an animation of the Moon’s full rotation, showing all sides of the Moon lighted by the Sun. Film images come from the Lunar Reconnaissance Orbiter (LRO).

Watching this video we can think of all sorts of oddities about the Moon that maybe we didn’t get answers to in our high school astronomy class, or Astronomy 101 at State U: Why do we see only one side of the Moon from Earth? Doesn’t that mean the Moon doesn’t rotate? And shouldn’t Pink Floyd have called the album, “Far Side of the Moon?”

When NASA ran the 24-second version of the video at the Astronomy Picture of the Day (APOD) site on September 16, 2013, NASA thoughtfully provided more information that you ever wanted:

Explanation: No one, presently, sees the Moon rotate like this. That’s because the Earth’s moon is tidally locked to the Earth, showing us only one side. Given modern digital technology, however, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie has now been composed. The above time-lapse video starts with the standard Earth view of the Moon. Quickly, though, Mare Orientale, a large crater with a dark center that is difficult to see from the Earth, rotates into view just below the equator. From an entire lunar month condensed into 24 seconds, the video clearly shows that the Earth side of the Moon contains an abundance of dark lunar maria, while the lunar far side is dominated by bright lunar highlands. Two new missions are scheduled to begin exploring the Moon within the year, the first of which is NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE). LADEE, which launched just over a week ago, is scheduled to begin orbiting the Moon in October and will explore the thin and unusual atmosphere of the Moon. In a few months, the Chinese Chang’e 3 is scheduled to launch, a mission that includes a soft lander that will dispatch a robotic rover.

July 2018: When do we fly the flag?

July 19, 2018

Caption from NASA: The American flag heralded the launch of Apollo 11, the first Lunar landing mission, on July 16, 1969. The massive Saturn V rocket lifted off from NASA’s Kennedy Space Center with astronauts Neil A. Armstrong, Michael Collins, and Edwin “Buzz” Aldrin at 9:32 a.m. EDT. Four days later, on July 20, Armstrong and Aldrin landed on the Moon’s surface while Collins orbited overhead in the Command Module. Armstrong and Aldrin gathered samples of lunar material and deployed scientific experiments that transmitted data about the lunar environment. Image Credit: NASA

[Yes, we’re running late with this post for July. Apologies. You can always check the list of all dates, or last year’s post.]

July 4. Surely everyone knows to fly the flag on Independence Day, the anniversary of the Declaration of Independence.*

In the month of the grand patriotic celebration, what other dates do we fly the U.S. flag? July 4 is the only date designated in the Flag Code for all Americans to fly the flag.  Three states joined the union in July, days on which citizens of those states should show the colors, New York, Idaho and Wyoming.

Plus, there is one date many veterans think we should still fly the flag, Korean War Veterans Armistice Day on July 27.  Oddly, the law designating that date urges flying the flag only until 2003, the 50th anniversary of the still-standing truce in that war.  But the law still exists.  What’s a patriot to do?

Patriots may watch to see whether the president issues a proclamation for the date.

Generally we don’t note state holidays or state-designated flag-flying events, such as Utah’s Pioneer Day, July 24, which marks the day in 1847 that the Mormon pioneers in the party of Brigham Young exited what is now Emigration Canyon into the Salt Lake Valley. But it’s a big day in Utah, where I spent a number of years and still have family. And I still have memories, not all pleasant, of that five-mile march for the Days of ’47 Parade, in that wool, long-sleeved uniform and hat, carrying the Sousaphone. Pardon my partisan exception. Utahns will fly their flags on July 24.

  • Idaho statehood, July 3 (1890, 43rd state)
  • Independence Day, July 4
  • Wyoming statehood, July 10 (1890, 44th state)
  • New York statehood, July 26 (1788, 11th state)
  • National Korean War Veterans Armistice Day, July 27 (flags fly at half-staff, if you are continuing the commemoration which was designated in law only until 2003)

* July 4? But didn’t John Adams say it should be July 2?  And, yes, the staff at Millard Fillmore’s Bathtub sadly noted that, at most July 4 parades, it appears no one salutes the U.S. flag as it passes, as the Flag Code recommends. MFB’s been fighting flag etiquette ignorance since 2006. It’s taking much, much longer than we wished.

The flag is one of four “mobility logos” placed on the rover’s mobility rocker arms.

This is an encore post.

Yes, this is an encore post. Defeating ignorance takes patience and perseverance.
