Humans do it quickly

Marshall Islands

A team of scientists from Japan have found evidence that the human settlement of the Marshall Islands in the central Pacific Ocean occurred almost immediately after those islands emerged from beneath the sea. Though it had been previously believed that a thousand years had to pass until these newly emerged islands had developed sufficient vegetation for humans to occupy them, the evidence from this study shows that humans not only showed up almost immediately, they acted to vegetate the island themselves in order to make it habitable.

The scientists drilled four cores just off the western shore of Laura Island, the largest island of Majuro Atoll, as well as thirteen trenches on that same island, in order to determine when the island first emerged from under the sea. They also excavated a well-preserved bank at the center of Laura Island to study the human occupation of the island.

What they found was that the Atoll emerged from underwater approximately 2000 years ago, triggered by a fall in sea level. More surprising, the first evidence of human settlement appeared to occur at almost the same time.

Gerry & The Pacemakers – Ferry Cross The Mersey

An evening pause: From 1965, the Top of the Pops show. I’ve always liked this song, “Ferry Cross the Mersey,” but it is also fun to watch early television, with the band attempting to simulate playing to the original recording, while the kids on the dance fall make believe they’re dancing as they repeatedly sneak peaks at the cameras.

Beethoven — second movement, Fifth Symphony, performed by NBC Symphony Orchestra conducted by Arturo Toscanini

An evening pause: This March 22, 1952 television performance of Beethoven’s Fifth Symphony from Carnegie Hall by the NBC Symphony Orchestra, conducted by Arturo Toscanini, was probably the most remembered by the generation of our parents. I show the second movement, because it happens to be my favorite. Listen as the opening theme returns several times during the piece, only changing the last time into something even more beautiful.

Watching Toscanini as he conducts is fascinating as well.

NASA science administrator Ed Weiler is retiring after 33 years

Science administrator Ed Weiler is retiring after almost 33 years at NASA.

Among Weiler’s many achievements, he was crucial to getting the Hubble Space Telescope launched. Even more important, though others had conceived the idea of using the shuttle to maintain Hubble, he designed the maintenance schedule for the telescope. Seven years before it was launched, he insisted that a regular schedule of repair missions be placed on the shuttle manifest. He also insisted that a duplicate of the telescope’s main camera be built, so that if anything went wrong with the first a repaired unit could be launched quickly. It was his foresight here that made the first repair of Hubble in December 1993 go so smoothly. For this, astronomers will always be grateful.

New images of Apollo landing sites on the Moon

The Lunar Reconnaissance Orbiter team have released new images of the Apollo 12, 14, and 17 landing sites on the Moon. Below is a cropped image of the Apollo 12 site, showing the trails left by astronauts Pete Conrad and Alan Bean when they walked from their lunar module to Surveyor 3, an unmanned lunar lander that had soft landed there two years earlier. The full image shows some incredible detail.

a Special Space and Aviation Artifacts Auction

Want a piece of space history? Over 800 space artifacts go up for auction beginning September 15. In addition to letters from Neil Armstrong and Alan Shepard, there’s this:

The First Lunar Bible: A flight-flown intact microfilm King James Bible containing all 1,245 pages. The bible was produced by the Apollo Prayer League, a group of NASA engineers, scientists, administrators and astronauts, and headed by NASA chaplain Rev. John Stout, who worked closely with the astronauts and NASA personnel. This lunar bible was originally slated to fly to the moon on Apollo 12, but a mistake on the lunar landing checklist resulted in the bible orbiting the moon in the Command Module. It was, then, placed on board Apollo 13, but due to a near-catastrophic explosion, the crew did not reach the moon, and instead returned along with the bible to Earth. Bibles were then given to Apollo 14 Lunar Module Pilot Edgar Mitchell who stowed them in his PPK bag and landed them safely on the moon February 5, 1971, on board lunar module Antares.
