Museos. AbandonedPorn: Abandoned everything. President Nixon: The moving speech that would have delivered if Apollo 11 astronauts could not return. By James Nye Published: 04:22 GMT, 26 August 2012 | Updated: 13:00 GMT, 26 August 2012 Amid the triumphant success of Neil Armstrong and Buzz Aldrin's successful moon-walk in July 1969, NASA and President Richard Nixon's White House breathed a heavy sigh of relief that he didn't have to deliver a speech to the nation entitled 'In Event of Moon Disaster'.

President Nixon: The moving speech that would have delivered if Apollo 11 astronauts could not return

The speech and a memo were prepared in the event that the two Apollo 11 astronauts did not manage to reconnect with their command module piloted by Michael Collins and could not return safely home to Earth. The enduring mystery of Hitler's monkeys. World Heritage Site. A UNESCO World Heritage Site is a place (such as a forest, mountain, lake, island, desert, monument, building, complex, or city) that is listed by UNESCO as of special cultural or physical significance.[1] The list is maintained by the international World Heritage Programme administered by the UNESCO World Heritage Committee, composed of 21 states' parties[2] which are elected by their General Assembly.[3] The programme catalogues, names, and conserves sites of outstanding cultural or natural importance to the common heritage of humanity.

Under certain conditions, listed sites can obtain funds from the World Heritage Fund. A lost city reveals the grandeur of medieval African civilization. 20th Century History. A Rare Look at the Tunnels Under San Francisco. In the early ’90s my friends and I used to tape flashlights to the handlebars of our bikes and go riding around in underground storm drain tunnels.

A Rare Look at the Tunnels Under San Francisco

There was a whole network of these tunnels under the city that sat empty for most of the year. We would go for miles snaking up and down the sides of the tubes, clapping and yelling to see how far our echoes would carry, eventually popping out in some other part of the city covered in cobwebs and bat guano. When the tubes got too small, we laid down on skateboards and kept going. If we found a flooded part, we taped garbage bags around our legs and crossed our fingers.

Year 2000 problem. The (French) sign reads "3 January 1900" instead of "3 January 2000" The Year 2000 problem (also known as the Y2K problem, the Millennium bug, the Y2K bug, or simply Y2K) was a problem for both digital (computer-related) and non-digital documentation and data storage situations which resulted from the practice of abbreviating a four-digit year to two digits.

Year 2000 problem

In 1997, The British Standards Institute (BSI) developed a standard, DISC PD2000-1,[1] which defines "Year 2000 Conformity requirements" as four rules: No valid date will cause any interruption in operations.Calculation of durations between, or the sequence of, pairs of dates will be correct whether any dates are in different centuries.In all interfaces and in all storage, the century must be unambiguous, either specified, or calculable by algorithmYear 2000 must be recognized as a leap year It identifies two problems that may exist in many computer programs.

A Perfect Solar Superstorm: The 1859 Carrington Event

Fortunately, it delivered only a glancing blow, and global communications continued to operate without disruption. In 1859 Earth wasn’t so lucky. The Carrington Event On the morning of September 1, 1859, amateur astronomer Richard Carrington ascended into the private observatory attached to his country estate outside of London. After cranking open the dome’s shutter to reveal the clear blue sky, he pointed his brass telescope toward the sun and began to sketch a cluster of enormous dark spots that freckled its surface. Suddenly, Carrington spotted what he described as “two patches of intensely bright and white light” erupting from the sunspots.

That night, telegraph communications around the world began to fail; there were reports of sparks showering from telegraph machines, shocking operators and setting papers ablaze. Last Week Tonight with John Oliver: Nuclear Weapons (HBO) Obama orders review of U.S. energy infrastructure. Apollo F-1 engines recovered from the bottom of the Atlantic by Bezos Expeditions. Bezos is certain it's from Apollo 11, but I haven't heard of a confirmation yet.

Everything has a serial number though, so once they find a readable one should be able to verify Yeah, he looked at the trajectory of Apollo 11 off the launch pad (as compared to all of the other Saturn V launches) and was able to get a rough idea of where those particular engines would have fallen in the ocean. I've heard that they have not identified any serial number anywhere yet, but NASA still has the records in its archives (or those of the contractors) so once the Bezos team finds a number they can check it out. Space.com had a article on this a few months ago and NASA actually has a map showing where each Saturn V first stage came down in the ocean. 20th Century History.
