I love rediscovering cool things. I'm sure I learned, at some point, that the Soviet Union had once sent probes to land on the surface of Venus. But I had completely forgotten this fact until today.
This photo comes from Venera 9, which landed on Venus on October 22, 1975. The lander remained operational for 53 minutes, which isn't bad considering we're talking about a planet with hydrochloric acid and hydrofluoric acid in the atmosphere, and a surface temperature (as measured by Venera 9) of 905° F.
The photo — at three different phases of processing — comes from the website of Don Mitchell, an enthusiast of Soviet space history. Mitchell did the processing that resulted in the clear, bottom image in this stack.
The upper image is the raw 6-bit data. The center images include the telemetry brust replacements, with remaining bursts blacked out. The 6-bit values have been transformed to linear brightness, using the published photometric function of the camera, and then converted to sRGB standard form (gamma 2.2). In the final version, I filled in missing regions, using Bertalmio's inpainting algorithm.

Thanks to OMG Facts for reminding me of this cool bit of history
Fascinating, now gimme a double latte. (AsapSCIENCE)
Since its publication in late 2015, science writer Oliver Morton’s The Planet Remade: How Geoengineering Could Change the World has swept many “best book” (best science book, best business book, best nonfiction book) and with good reason: though it weighs in at a hefty 440 pages and covers a broad scientific, political and technological territory, few science books are more important, timely and beautifully written.
After years of speculation and wrangling over his remains, Kennewick Man turns out to be closely related to contemporary, local Native Americans after all. Discovered near Kennewick, Wash., in 1996, the skeleton ended up in a tug of war between tribes in the pacific northwest who wanted to bury the remains, and scientists who wanted […]
White hat hackers get paid to find holes in their own employers’ online systems, and plug those holes before they become serious security risks. It’s a job that pays handsomely…mostly because few job candidates, even experienced IT professionals, have the skills to scamper over firewalls and infiltrate the deepest recesses of a battle-tested network. But […]

The Blumoo Universal Remote, now just $52.99 in the Boing Boing Store, harnesses the audio power of all your household equipment right […]
You may not love Microsoft Word, but you’ve definitely used it. Other than being one of the most ubiquitous programs on the planet, it’s been the go-to word processing system for more than a quarter-century because it’s as basic as it gets. But occasionally, you’ve got assignments that beg for a lot more options than simple […]
