Tsar Bomba – Unclassified Footage

Rosatom has released previously classified footage of the largest bomb to ever be detonated, Tsar Bomba.

With a yield of 50 megatons (50 million tons), equal to around 3,800 Hiroshima bombs, the weapon was set off over Novaya Zemlya on October 30, 1961

The second shuttle launch (STS-27) after the Challenger disaster almost ended in disaster.

One report describes the crew as “infuriated” that Mission Control seemed unconcerned. When Commander Gibson saw the damage he thought to himself, “We are going to die”, and did not believe that the shuttle would survive reentry; if instruments indicated that the shuttle was disintegrating, he planned to “tell mission control what I thought of their analysis” in the remaining seconds before his death.

The shuttle Atlantis actually sustained more damage than what would bring down Columbia in 2003. The Top Secret payload (a surveillance satellite for the US DOD) meant that communication with the ground was done using a slower method of encryption which could have resulted in lower quality images for analysis (eg. higher compression for faster transmission over a slow line).

How Amsterdam’s Airport Is Fighting Noise Pollution With Land Art

For years, residents complained about the incessant rumbling din produced every time an aircraft took off. This type of noise, called ground-level noise, propagates across the flat and featureless Haarlemmermeer landscape that has nothing in between—no hills, no valleys— to disrupt the path of the sound waves. When the airport opened its longest runway in 2003, residents could hear the din more than 28 km away.

To tackle the noise problem, the airport brought in an unlikely candidate—an architecture firm called H+N+S Landscape Architects and artist Paul De Kort.

When slaves and free men were shipwrecked together

As they landed on the island on the night of the wreck, some of the crew supposed it inhabited. But the dark-skinned “locals” they encountered had come on the same ship, just a different part of it. Below deck 160 or so slaves had languished, men, women and children. Nearly half of them had died in the night, probably drowned under the nailed-down hatches. That still left 88, two-thirds of them men, now unshackled.

Plastic Bag Found at the Bottom of World’s Deepest Ocean Trench

A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 36,000 feet inside the Mariana Trench. Scientists found it by looking through the Deep-Sea Debris Database, a collection of photos and videos taken from 5,010 dives over the past 30 years that was recently made public.

Books from 1923 to 1941 Now Liberated!

The Internet Archive is now leveraging a little known, and perhaps never used, provision of US copyright law, Section 108h, which allows libraries to scan and make available materials published 1923 to 1941 if they are not being actively sold. Elizabeth Townsend Gard, a copyright scholar at Tulane University calls this “Library Public Domain.” She and her students helped bring the first scanned books of this era available online in a collection named for the author of the bill making this necessary: The Sonny Bono Memorial Collection. Thousands more books will be added in the near future as we automate. We hope this will encourage libraries that have been reticent to scan beyond 1923 to start mass scanning their books and other works, at least up to 1942.
