ARCHELON

Postcard NL-2619878 from the Netherlands was a produced by ARCHELON, the Sea Turtle Protection Society of Greece, showing a loggerhead sea turtle (Caretta caretta), an endangered species protected by the International Union for the Conservation of Nature. Founded in 1983, ARCHELON aims to protect sea turtles and their habitats in Greece through research, public awareness campaigns, and restoring habitats. It operates a rescue center built in 1994.

In my previous blog the World Turtle Day, Sea Turtle Oversight Protection (STOP) in Florida was featured for their work in rescuing those new sea turtle hatchlings disoriented by the street lights. You can still help by becoming a supporting member or joining a rescue walk in the 2014 season that lasts from May to October.

Space Shuttle Columbia

Twenty five years ago today, Space Shuttle Columbia lifted off on August 8, 1989 for a five-day mission STS-28. It was the 30th NASA Space Shuttle mission overall, the 4th secret military mission for the U.S. Department of Defense, and the 8th flight of Space Shuttle Columbia. It was also Columbia's first flight since STS-61-C in January 1986, the mission directly preceding the Challenger disaster.

The featured postcard shows Columbia's Crew Insignia for mission STS-4, the 4th NASA Space Shuttle mission overall, and also the 4th flight for Space Shuttle Columbia. The mission, launched on June 27, 1982 and landed a week later on July 4, 1982,  carried numerous scientific payloads and military missile detection systems. The insignia shows the Columbia trailing USA nation's colors in the shape of her flight number 4, representing the fourth and final flight of the test phase. Space Shuttle was officially declared to be operational thereafter.

Columbia was destroyed on February 1, 2003 during the re-entry of the atmosphere at the end of a 16-day multi-disciplinary microgravity and Earth science research mission STS-107.

Michelangelo's David

Achilles was killed out of his heel. Now, David is at risk of collapsing due to his weak ankles. According to a recent report published in the Journal of Cultural Heritage from the National Research Council in Italy, micro-fractures have been found in the ankle and leg areas at Michelangelo's famous statue.

The "David" statue dates from the early 16th century. Initially for more than three centuries, "David" stood outside at the Piazza della Signoria in Florence, exposing to the elements. It was moved inside to the Galleria dell'Accademia in 1873, with a copy placed in the piazza. Research shows that its left leg and the tree stump, where much of its 5.5-ton weight rests, has been weaken over the years due to vibrations caused by the tourists and passing automobile traffic. The quality of the marble used by Michelangelo was also a contributing factor.

Recommendations have been made to minimize the risk by retrofitting an earthquake-proof room or moving the statue to a more stable area outside the city.

For people in Las Vegas, there is not worry as we have an exact replica of Michelangelo's David as shown on postcard US-1655839 to Germany. It is located at the Appian Way Shops inside Caesars Palace Casino in Las Vegas, made from Carrara marble. He stands 5.17-meter or 17-feet tall and weighs more than nine tons.
