"Voyager's main transmitter shines at a feeble 22 watts, which is comparable to a car-mounted police radio or -- in visible light -- a refrigerator light bulb. Though incredibly weak by the standards of modern wireless communications, Voyager's signal is astoundingly bright when compared to most natural objects studied by radio telescopes." -- Even as Voyager 1 has left the Solar System (again), it can still be easily detected by telescopes on Earth, showing once again there ain't no stealth in space.
"It is made out of velcro-like fabric that lines the Russian food containers [that are] found here on the International Space Station."
New Scientist magazine has posted a nifty interactive infographic that illustrates how many Earth-like planets might exist, based on observations from the Kepler Space Telescope. The orbital observatory has catalogued 151 exoplanets based on examination of 0.28% of the sky. [more inside]

As the Cygnus cargo spacecraft makes its initial demostration flight to the International Space Station, the question arises, what is the ISS for?
After nearly 5000 launches, we've put a lot of objects in space. Amongst them are around half a million pieces of debris, generated by explosions, breakups and collisions (previously). With speeds of up to 15 km/s, even tiny fragments can cause major damage and the creation of further debris. The Kessler Syndrome describes a situation where the cascade of collisions creates an exponential increase in the amount of debris, leading to a potentially impassable artificial belt in LEO lasting for generations.

How often does a great story dominate the headlines, only to be dropped from the news cycle? How often do journalists tell us of a looming danger or important discovery – only to move quickly to the next new thing? What really happened? How did these events change us? And what are the lingering consequences that may affect our society to this day? These are the questions we are answering at Retro Report, an innovative documentary news organization launched in 2013 as a timely online counterweight to today’s 24/7 news cycle. Combining documentary techniques with shoe-leather reporting, we peel back the layers of some of the most perplexing news stories of our past with the goal of encouraging the public to think more critically about current events and the media in ~10 minute segments.

The Smithsonian's National Air and Space museum is running an exhibit showing the ingenuity of design inherent in the spacesuits used by NASA astronauts. It includes some very cool x-ray photographs of the equipment by Mark Avino. [via]
It's 1963. You're in a cold war with Russia. You want to keep up communication capabilities globally. Communication satellites haven't come into their own. The ionosphere is fickle and jammable. What do you do? You fire 480 million tiny copper wires into space to create an artificial dipole antenna belt around the earth. You call it Project West Ford. It works. [more inside]
"Imagine being alone, in space. Just you and your shiny spacesuit and your tiny metal capsule, the world splayed beneath you in swaths of blue and swirls of white. The only immediate link to the humans below you being a faint, crackling radio line back to Earth. ... [Leroy Gordon Cooper, Jr.], the seventh member of the "Original Seven," spent a total of one day, 10 hours, 19 minutes, and 49 seconds in space, making 22 full orbits of the planet before splashing down in the Pacific on May 16, 1963. (His flight overall took 34 hours.) Over the course of his long voyage, Cooper had a dinner of "powdered roast beef mush" washed down with water. He captured mesmerizing pictures of the Earth below. He became the first American to sleep in space. The story doesn't end there, though: Cooper also ran into some trouble." Imagine being alone in space ... and almost not making it back.

A few weeks ago, Italian astronaut Luca Parmitano (@astro_luca) almost drowned during a spacewalk when his helmet started uncontrollably filling with water, possibly from a leaky spacesuit cooling system. (See previous MeFi discussion on the incident.) A week later, his fellow ISS astronaut Chris Cassidy posted two videos online showing the actual spacesuit and using it to illustrate the problem. All future US and European spacewalks have been halted while the incident is being investigated, although the Russian ones are continuing, as they use different suits. Yesterday, Luca published a scary new entry on his in-orbit blog, where he not only gave all the horror-movie details, but also revealed that he nearly chose to depressurize his suit outside the ISS in order to survive.

Syd Mead's Stanford Torus Illustrations for National Geographic got him the job, 40 years later, of designing Elysium for Neill Blomkamp. Mead calls the unique visual effect of these interior drawings, in which the horizon wraps up and over the viewpoint, 'inverse perspective'. This effect, and others like it, have been explored in the concept art for large, rotating, space habitats at least since the early 1960s. [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.

Tekhnika Molodezhi was the Popular Mechanics of the Soviet Union. The magazine, whose name means Technology for the Youth, had illustrations of everything from space stations, computerized farming, transport of the future, friendly robots, to more abstract images. If you don't want to hunt through the archive, Mythbuster's Tested website has a gallery of 201 great images from the magazine.
The first official trailer of In Saturn's Rings (formerly Outside In) has been released to universal acclaim. The movie (to be completed in 2014) is made exclusively from real photos taken by spacecraft, mostly Cassini-Huygens.

Fifty years ago today, Valentina Tereshkova became the first textile factory worker, first civilian and of course first woman in space. She completed 48 orbits, in the process amassing more space time than any of the American astronauts had logged. It would be almost twenty years before a second female astronaut got into space, slightly more than that for the first American woman. In total, fiftyseven women have flown into space, or roughly ten percent of the total number of astronauts.
Project Kronos: is a documentary film set in the not too distant future, following a mission to achieve interstellar space travel. As the mission unfolds with extraordinary results, the scientists find themselves dealing with a much bigger agenda.
The Welsh Space Campaign. The suit is made of the fabric woven in the last remaining wool mills in Wales. The astronaut boots are traditional Welsh clogs crafted by a traditional clog maker. The whole pressure system that will enable the astronaut to sustain life in outer space was built by a Welsh plumber. The aim of the designer is to reveal that Wales has the capacity to explore space, and to show that off-world culturalisation can be achieved through a collective communitarian effort; as a way to allow the people involved to reconsider their role and skill in relation to these cosmic contexts. -- We Make Money Not Art

UFO is a 1970 British science fiction television series about a secret military organization which defends the Earth from Alien invaders. The series was created by Gerry & Sylvia Anderson, who previously created the "Supermarionation" puppet TV series in the 1960's (Thunderbirds, Fireball XL-5), and would later create Space: 1999. The production is highly stylized, from the cars, hair styles, and future fashions to Ebert-worthy parties of the future, mesh space shirts and groovy theme music. [more inside]

Chris Hadfield has captured the world's heart, judging by the 14m YouTube views of his free-fall rendition of David Bowie's "Space Oddity", recorded on the International Space Station (ISS). The Canadian astronaut's clear voice and capable guitar-playing were complemented by his facility in moving around in the microgravity of low-earth orbit. But when the man fell to Earth in a neat and safe descent a few days ago, after a five-month stay in orbit, should he have been greeted by copyright police?

Skylab, NASA's budget space station, launched 40 years ago today. Designed as an orbiting optical laboratory, she served as a cold war weapon, underwent an historic salvage job, and was the site of America's first space mutiny before landing hard in Australia while waiting for the Space Shuttle to be invented.
Today. the day after astronauts detected and repaired a "serious but not life-threatening" ammonia leak on the space station, Commander Chris Hadfield has passed over command of the space station.
