We know space is big, but trying to understand how big is tricky. Say you stare up at the sky and identify stars and constellations in a virtual planetarium, you can't quite fathom how far away all those stars are (previously, twice). Even if you could change your point of view and zoom around in space to really see 100,000 nearby stars (autoplaying ambient music, and there are actually 119,617 stars mapped in 3D space), it's still difficult to get a sense of scale. There's this static image of various items mapped on a log scale from XKCD (previously), and an interactive horizontal journey down from the sun to the heliosphere with OMG Space (previously). You can get a bit more dynamic with this interactive Scale of the Universe webpage (also available in with some variants, if you want the sequel [ previously, twice], the swirly, gravity-optional version that takes some time to load, and the wrong version [previously]), but that's just for the scale of objects, not of space itself. If you want to get spaced out, imagine if If the Moon Were Only 1 Pixel, and travel from there (previously). This past March, BBC Future put out a really big infographic, which also takes a moment to load, but then you can see all sorts of things, from the surface of Earth out to the edge of our solar system.
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.
In 1972, Tom Wolfe was assigned to do a piece for Rolling Stone on Apollo 17, NASA's last moon mission (Google book preview). That turned into a four-part series on the astronauts, written in a frantic three weeks. From there, he thought he could quickly expand the piece into a book (Gbp). But that book, on what makes an astronaut, ended up taking a much broader scope and more time. In 1979, The Right Stuff was published, and later was made into a well-regarded 3 hour movie. A few years later, Andrew Chaikin started on a similar path to Wolfe, more broadly documenting the US moon missions in his book, A Man on the Moon. The book was published in 1994, and HBO used it as the basis of a 12-part mini-series that they aired in 1998, titled From the Earth to the Moon. [more inside]
"The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet." Before we get into terraforming, what about the space between worlds? NASA has a website dedicated to discussions of space settlements (previously), many going back to the 1970s, as seen in the CoEvolution Book on space settlement and the NASA Ames/Stanford 1975 Summer Study. There is also concept art from the 1970s by Don Davis (prev: 1, 2, 3) and Rick Guidice. Escaping from that orbit, there's also a toroidal space colony as imagined in the 1982 book Walt Disney's EPCOT, and more recently, a ton of neat imagery on Bryan Versteeg's Spacehabs website.

NASA's Space Food Hall of Fame
Today's space food has come a long way since the Mercury Program of the early 1960s. When John Glenn first tried apple sauce from a squeeze tube onboard his Friendship 7 spacecraft in 1962, who could have dreamed that later astronauts would be able to choose from such a wide variety of foods?See also: Food in Space: Great Photos of Astronaut Meals, from the Early Space Voyages to Today, on io9.

Since late January of 2010, the International Space Station was able to access the Internet for personal use, leading to the first tweet from space. The previous tweets were e-mailed to the ground where support personnel posted them to the astronaut's Twitter account. Currently there are 17 active NASA astronauts and 6 internatual'nauts tweeting from on high. If their words aren't enough, they're also posting pictures, primarily from Soichi Noguchi (@Astro_Soichi) and José Hernández (@Astro_Jose, whose socio-political messages were covered previously).

Where am I now? Travelin' 1.18km/s(2646mph). 70,289km from the Moon. 19 hrs! RU Excited? I am! #lcross
On October 9th, NASA spacecraft will run into the moon, and on purpose. The Lunar Crater Observation and Sensing Satellite (LCROSS) and its rocket's Centaur upper stage will impact the moon, with the goal of sending some of the (possibly present) ice above the lunar surface. Once out of the eternal shade of the moon's south pole, sunlight will break the ice up into H+ and OH- molecules, which can be detected by the Lunar Reconnaissance Orbiter (LRO). The initial impact site was the crater Cabeus A, but the target was later changed to Cabeus (proper), selected for highest hydrogen concentrations with the greatest level of certainty, and for the high-contrast back drop to detect ejecta and vapor measurements. NASA has provided guides for amateur observations of the impact, a facebook group, and a Twitter feed so you don't miss the moment.
"The arc of the Milky Way seen from a truly dark location is part of our planet's natural heritage," said Connie Walker, and astronomer from the U.S. National Optical Astronomy Observatory in Tucson, Arizona. Yet "more than one fifth of the world population, two thirds of the U.S. population and one half of the European Union population have already lost naked eye visibility of the Milky Way." In these areas, people are effectively living in perennial moonlight. They rarely realize it because they still experience the sky to be brighter under a full moon than under new moon conditions. "Reducing the number of lights on at night could help conserve energy, protect wildlife and benefit human health," astronomer Malcolm Smith of the Cerro Tololo Inter-American Observatory in Chile. One study found an increased risk of breast cancer for women living in areas with the most light pollution (abstract). Some communities are embracing their dark skies, such as the New Zealand community of Tekapo, possibly home to first "Starlight Reserve," waiting on UNESCO's official approval.
