The recovery of Salyut 7
In 1985, the Soviet Union's space station Salyut 7 was crippled by an total electrical failure. Reactivating it would require a manual docking and working in bitter cold, 130 miles above the planet.

You invest so much in it, don't you? It's what elevates you above the beasts of the field, it's what makes you special. Homo sapiens, you call yourself. Wise Man. Do you even know what it is, this consciousness you cite in your own exaltation? Do you even know what it's for?

2006 novel Blindsight [full text]

Storm Chasing on Saturn with Cassini
.] - "The sun is slowly rising over Saturn's north pole, exposing an immense six-sided hurricane. The storm, big enough to swallow four Earths, was first spotted by the Voyager missions in the early 1980s. [Cassini
] will be passing directly over the north pole with its cameras pointing down later this month." (previously 1

The Miura fold
, a type of rigid origami
that works by folding flat, rigid sheets with hinges, has a number of uses. For instance, It's great for folding a map, because Interdependence of folds means that it is very difficult to reverse them and the amount of stress place on the map
, and can be used on solar panels that need to be folded and unfolded by automation
, as deployment only requires one motor, and to transport materials for telescope lenses that originally would be too big to fly into space
. Here's one schematic for duplicating the Miura fold
(PNG), and a simplified version
(YouTube). More information and fun with scientific origami
at Robert J. Lang's origami website

Astronaut Sally Ride and the Burden of Being The First.
'Tampons were packed with their strings connecting them, like a strip of sausages, so they wouldn’t float away. Engineers asked Ride, “Is 100 the right number?” She would be in space for a week. “That would not be the right number,” she told them. At every turn, her difference was made clear to her. When it was announced Ride had been named to a space flight mission, her shuttle commander, Bob Crippen, who became a lifelong friend and colleague, introduced her as “undoubtedly the prettiest member of the crew.” At another press event, a reporter asked Ride how she would react to a problem on the shuttle: “Do you weep?”'

Tonight at 7pm
PDT, after years in development, SpaceX will reveal a new manned version of the Dragon spacecraft
. Elon Musk said
that Dragon 2 will look like "a real alien spaceship", leading to speculation what it will looks like, including this artists interpretation
at ExtremeTech. According to Musk
, Dragon 2 will have larger windows for astronauts to see outside, and "landing legs that pop out of the bottom" and "side-mounted thruster pods" to allow for propulsive landings on land.

Archaeology, Anthropology and Interstellar Communication
is a free book (PDF) from NASA. The premise is that communication with alien lifeforms will have some (cautious) analogues to interpreting past cultures, and to the work that anthropologists and linguists do cross-culturally. Among the 16 chapters are: Beyond Linear B - The Metasemiotic Challenge of Communication with Extraterrestrial Intelligence; Learning To Read - Interstellar Message Decipherment from Archaeological and Anthropological Perspectives; and, Mirrors of Our Assumptions: Lessons from an Arthritic Neanderthal.

Trip to Mars Doesn’t Have to Break the Bank
Just days after the launch of India’s Mangalyaan satellite, NASA sent off its own Mars mission, five years in the making, named Maven. Its cost: $671 million. The budget of India’s Mars mission, by contrast, was just three-quarters of the $100 million that Hollywood spent on last year’s space-based hit, “Gravity.”
“The mission is a triumph of low-cost Indian engineering,” said Roddam Narasimha, an aerospace scientist and a professor at Bangalore’s Jawaharlal Nehru Center for Advanced Scientific Research.
“By excelling in getting so much out of so little, we are establishing ourselves as the most cost-effective center globewide for a variety of advanced technologies,” said Mr. Narasimha.

When can I spot the Space Station? The International Space Station can easily be spotted with the naked eye. Because of its size (110m x 100m x 30m) it reflects very much sunlight.
This simple tool will tell you all of the opportunities you can view the ISS over the next ten days, along with a brightness index and a map tracing its transit across your local sky. The red line shows where the ISS is sunlit and visible. On the blue line the ISS is in the Earth's shadow and invisible or it is less than 10° above the horizon. [more inside]

Van Cleef & Arpels
, purveyors of super fine jewelry, have created the Midnight Planetarium
, which holds part of the solar system on your wrist:
This new Poetic Complication timepiece provides a miniature representation of the movement of six planets around the sun and their position at any given time. Earth and Mercury, Venus, Mars, Jupiter and Saturn are set in motion thanks to a self-winding mechanical movement of great complexity: equipped with an exclusive module developed in partnership with the Maison Christiaan van der Klaauw, it contains 396 separate parts. The movement of each planet is true to its genuine length of orbit: it will take Saturn over 29 years to make a complete circuit of the dial, while Jupiter will take almost 12 years, Mars 687 days, Earth 365 days, Venus 224 days and Mercury 88 days.
