45 Years ago: A Giant Leap for Mankind!

From the annals of American space exploration!

In what was at the time one of the highest achievements of American engineering and technology, forty-five years ago, on 16 July 1969 the APOLLO 11 mission lifted-off from Cape Canaveral, Florida.

The complex mission, carried out in flawless manner by astronauts Neil Armstrong,  Michael Collins, and Edwin Aldrin,  involved several vehicles and complex maneuvers.

Mission Commander Neil Armstrong, who was the first human being to set foot on the Moon, is remembered for this and other feats  during his career, but mainly for his often quoted “One small step for a man, one giant leap for mankind! Armstrong who was a military pilot in active duty during the Korean War and one of the astronauts aboard the Gemini 8 mission, passed away in August 2012.

Commander Michael Collins, a former U.S. Air Force Pilot, was pilot of the ‘Columbia’ Command/Service module that remained in Lunar orbit while Armstrong and Aldrin Jr. descended to the Moon’s surface riding the “Eagle’ Lunar module.  The Columbia was the rocket spacecraft that brought the three APOLLO 11 astronauts back to the Earth’s environs for their final landing aboard their capsule for a splash-down in the Pacific.

Commander Edwin Aldrin Jr., also an air force pilot who saw active duty during the Korean War, was the pilot of the ‘Eagle’ Lunar Module, responsible for touching down on the Moon’s surface and for lifting-off from the Moon to ascend to the orbiting Columbia command module for the ride back to Earth.

On this day, the 45th anniversary of such an excellent accomplishment and triumph of the collective American spirit, let us all trust we shall be able to recapture the same leadership, unity of purpose, collective dedication to a national objective, and good all-American roll-up-your-sleeves-and-get-to-work ethic to reapply them to confronting the challenges of global warming, sea level change and climatic extreme events that so threaten our nation and all of humankind.

"One small step for a man, one giant step for mankind"
“One small step for a man, one giant step for mankind”

May our grandchildren in the year 2059 be able to look back and thank the leadership, unity of purpose and clear vision of their forefathers, our generation, who had the guts and the wisdom to put aside ideological differences to work for the common good of country and planet Earth. May they also be able to celebrate yet another giant leap for humankind!

5 May 2012: How close was the Moon?

The Moon, our Earth’s only natural satellite, orbits our planet in an elliptical path ranging in distance from 405,000 kilometers at its farthest point [apogee] to 363,000 kilometers, in round numbers, at its closet [perigee].

When a full Moon takes place when our satellite is at its perigee a phenomenon known as Super-Moon occurs, where our satellite appears much brighter and larger than average to the naked eye.

On Saturday 5 May 2012 around 11:30 p.m. EST the Moon entered its full phase while it was at its perigee giving observers on Earth the view of a celestial object that appeared 30% brighter and 14% bigger than other full Moons. In fact, this Super-Moon will be by far the biggest and brightest on all full Moons in 2012.

Having had advanced notice of this Super-Moon event I armed myself with tripod and camera, and taking advantage of wonderful clear skies over southeast Florida I captured the full Moon for my files. Following below are a couple of the photos I took:

It is clear the Moon has not only fascinated humankind since our ancestors first appeared on the Earth, but it has also exerted a profound influence on a wide range of aspects of human activity from religion to mathematics, agriculture to calendars and many more. Beyond these, the physical effects on Earth such as the tides are a daily reminder of the forces generated by the interaction of our planet and its satellite.

The Moon is the only planetary body in the whole universe other than Earth where humans have set foot.I believe many of us remember or are familiar with the words on Neil Armstrong, one of the Apollo 11 astronauts, as he set foot on the surface of the Moon on 20 July 1968. “That’s one small step for man,……one giant leap for mankind” were the first words of Neil Armstrong as he descended from the lunar module and stood of soil that was more than 4 billion years old. What a moment it was! Something to think about as some here on Earth watched the Super-Moon of 5 May 2012.

NASA’s Apollo program continued through 1972 both deploying experiments and scientific equipment of the Moon’s surface and bringing back hundreds of pounds of samples of Lunar soil and rocks for study and analysis here on Earth. Several of the Apollo missions deployed continuously improved versions of an apparatus known as a retro-reflector array, on different sites on the Moon’s surface, which are still used to bounce back laser light beamed to the Moon through an Earth-based telescope. It is that laser beam that is sent back to Earth by the retro-reflector array on the Moon that allows us to continuously measure the distance between these two bodies to an accuracy of a millimeter or so.

Beyond the proven scientific facts fostered by the work of NASA and others on Earth, the Moon has been linked to a wild range of unexplained, esoteric or otherwise non-scientific phenomena including various aspects of human behavior, seismic events, and even the end of the world as we know it.

While viewing the Super-Moon of 5 May 2012 I couldn’t help but think of what the view of the Earth would have been like at the same moment, We are talking of an observer on the Moon’s surface on 5 May 2012 would have had a great view of a Super-Earth! Our beautiful Blue Planet, spaceship Earth on which humankind sails through space, and which we must protect and defend so that our descendants may also enjoy beautiful Super-Moons hundreds or thousands of years from the present.
