Nixon was president, Watergate was still a third-rate burglary, and Tom and I were left feeling anxious, paranoid, and bored. We were both admirers of Mailer—the tough little reefer smoker, contrarian wordsmith, libertarian politico, and no-nonsense ladies’ man—so the story about the Voyage Beyond Apollo stirred our interest.
“They’ve cleverly organized this thing on a ship, you dig, that way no one can crash it,” mused Forcade. He theorized that the cruise was just a cover for an elite conclave conspiring to jettison Earth once they’d totally ravaged it, and establish an exclusive colony for the rich and powerful in space. Everyone else would be left to fight over dwindling resources and perish in the terrestrial ruins. “Mailer is either in on the scam or they’ve suckered him into it. We have got to get on board that ship,” Tom said, “find out what these motherfuckers are up to, blow their cover, and rescue Mailer before it’s too late.”
Under the influence of a fresh shipment of Tom’s Columbian import, I thought it seemed like an entirely reasonable plan…

[space] Technoarchaeology: How to revive a satellite … the amazing story of how communication has been re-established with a satellite last communicated with in 1998 … ‘This initial contact indicates that the satellite’s computer and radios are functioning. The next steps are to determine more fully whether its control systems work as expected and test its instrumentation and propulsion. The team must fire its rockets by mid-June to reposition ISEE-3. The next big challenge will come when the satellite swings around the moon onto its shadowed side and is cut off from the sun. The craft will power down for the first time in many years, and the team hopes when it sees it again, it will wake up and resume communications. It has lasted this long, and the group hopes for many more years to come.’
[space] SuitSat1: A Spacesuit Floats Free … slightly disturbing picture of a empty spacesuit floating away from the International Space Station … ‘The unneeded Russian Orlan spacesuit filled mostly with old clothes was fitted with a faint radio transmitter and released to orbit the Earth. The suit circled the Earth twice before its radio signal became unexpectedly weak.’

The photos were stored with remarkably high fidelity on the tapes, but at the time had to be copied from projection screens onto paper, sometimes at sizes so large that warehouses and even old churches were rented out to hang them up. The results were pretty grainy, but clear enough to identify landing sites and potential hazards. After the low-fi printing, the tapes were shoved into boxes and forgotten.
They changed hands several times over the years, almost getting tossed out before landing in storage in Moorpark, California. Several abortive attempts were made to recover data from the tapes, which were well kept, but it wasn’t until 2005 that NASA engineer Keith Cowing and space entrepreneur Dennis Wingo were able to bring the materials and the technical know how together.
When they learned through a Usenet group that former NASA employee Nancy Evans might have both the tapes and the super-rare Ampex FR-900 drives needed to read them, they jumped into action.

[space] Skylab 4 Rang in the New Year with Mutiny in Orbit … the little known story on a mutiny in space … ‘Long work periods and seemingly endless lists of tasks took their toll on the rookie astronauts. The crew found themselves exhausted, falling badly behind schedule. NASA was pushing them too hard, they said, and they couldn’t keep working such long hours. Ground crews in mission control disagreed. They felt that the astronauts were complaining needlessly, that they should be working through their meal times and rest days to catch up. It was expensive having a crew in orbit for 84 days, and NASA intended to get all the work out of the men it could manage. About six weeks into the flight, a few days before New Year’s Eve, the Skylab 4 crew hit their breaking point…’

The Sun is represented by the Globe arena in Stockholm, the largest spherical building in the world. The planets are placed and sized according to scale with the inner planets being in Stockholm and Jupiter at the International airport Arlanda. The outer planets follow in the same direction with Saturn in Uppsala and Pluto in Delsbo, 300 km from the Globe. The model ends at the Termination shock, 950 km from the Sun.’

According to lunar scientist Paul Spudis: For forty-odd years, the flags have been exposed to the full fury of the Moon’s environment – alternating 14 days of searing sunlight and 100° C heat with 14 days of numbing-cold -150° C darkness. But even more damaging is the intense ultraviolet (UV) radiation from the pure unfiltered sunlight on the cloth (modal) from which the Apollo flags were made. Even on Earth, the colors of a cloth flag flown in bright sunlight for many years will eventually fade and need to be replaced. So it is likely that these symbols of American achievement have been rendered blank, bleached white by the UV radiation of unfiltered sunlight on the lunar surface. Some of them may even have begun to physically disintegrate under the intense flux.

[space] Was Neil Armstrong a real hero? … ‘The weekend’s retelling of the 1969 moon landing reminded us just how risky it was and how Armstrong’s quick wits and calmness saved the day. The Eagle landing craft contained no more computer power than a modern washing machine, and was heading slightly off course for the rocks when Armstrong took over the controls manually. He landed with 20 seconds’ worth of fuel, and got the Eagle back up again to rendezvous with Apollo 11. There was no backup plan, no way of rescuing the crew. Sitting in the co-pilot’s seat with his spear (well, you never know, do you?), even Achilles might have been grudgingly impressed, though Armstrong’s lack of melodrama would have annoyed him. And therein perhaps lies the clincher for Armstrong’s heroic status. No boasting, no bullying, just a soft-spoken man who insisted he was only doing his job.’

Even if we could find a way to increase the speed of our spacecraft a hundredfold — about the same ratio of speeds between a horse-drawn cart and a 747 jet plane — they would still take almost a thousand years to reach nearby stars, and as long to return. And while exciting theoretical research is under way into pilotless probes to the stars, the real possibility of large-scale human interstellar culture is considerably less thrilling.
Think about it. No salvation from population pressure on the shores of alien worlds. No release from the threats of biosphere degradation in the promise of new biospheres. No escape from our own destructive tendencies by spreading out among the stars like seedpods in the wind. For as many epochs in the future as there are epochs of human history in the past, we may simply have to make do, get by with what we have and, in the end, learn to get along.
[life] What is the most astounding fact about the Universe? … answered by Astrophysicist Dr. Neil DeGrasse Tyson … ‘So that when I look up at the night sky and I know that yes, we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up – many people feel small because they’re small and the Universe is big – but I feel big, because my atoms came from those stars. There’s a level of connectivity. That’s really what you want in life, you want to feel connected, you want to feel relevant you want to feel like a participant in the goings on of activities and events around you That’s precisely what we are, just by being alive…’

[space] Methone, an egg in Saturn orbit? … fascinating blog entry with pictures about a recently discovered moon of Saturn … ‘Methone is really shockingly round. Some of the other small moons that orbit near the rings have a smoothed appearance, but they all still have some craters or some topography. The smoothness probably results from these things collecting dust, a substance that there is a lot of in this part of the Saturn system, but it’s kind of hard to understand what could make the dust slide around to fill every topographic low on this little world, covering it with what’s essentially a global ocean of very puffy dust. I think the roundness tells us that whatever Methone is made of, that material behaves like a liquid — it has no strength to hold any shape whatsoever.’

[life] Kevin Kelly – We Are Stardust:‘Where did we come from? I find the explanation that we were made in stars to be deep, elegant, and beautiful. This explanation says that every atom in each of our bodies was built up out of smaller particles produced in the furnaces of long-gone stars. We are the byproducts of nuclear fusion. The intense pressures and temperatures of these giant stoves thickened collapsing clouds of tiny elemental bits into heavier bits, which once fused, were blown out into space as the furnace died. The heaviest atoms in our bones may have required more than one cycle in the star furnaces to fatten up. Uncountable numbers of built-up atoms congealed into a planet, and a strange disequilibrium called life swept up a subset of those atoms into our mortal shells. We are all collected stardust. And by a most elegant and remarkable transformation, our starstuff is capable of looking into the night sky to perceive other stars shining. They seem remote and distant, but we are really very close to them no matter how many lightyears away. All that we see of each other was born in a star. How beautiful is that?’

The Moon rocks, laying on the surface for billions of years, contain information about the universe from early era of the universe, which also reveals the conditions of Earth shortly after it was formed.’

They were the three-man crews of the nine Apollo missions that traveled to the moon between 1968 and 1972, six of which landed there successfully (three men went twice). But only the last three saw a full Earth.’
The space vehicle is shoddily constructed, running dangerously low on fuel; its parachutes — though no one knows this — won’t work and the cosmonaut, Vladimir Komarov, is about to, literally, crash full speed into Earth, his body turning molten on impact. As he heads to his doom, U.S. listening posts in Turkey hear him crying in rage, “cursing the people who had put him inside a botched spaceship.

[space] Space Stasis … Neal Stephenson takes a fascinating look at path dependence and lock-in within the business, idea and design of rockets… ‘To employ a commonly used metaphor, our current proficiency in rocket-building is the result of a hill-climbing approach; we started at one place on the technological landscape – which must be considered a random pick, given that it was chosen for dubious reasons by a maniac – and climbed the hill from there, looking for small steps that could be taken to increase the size and efficiency of the device. Sixty years and a couple of trillion dollars later, we have reached a place that is infinitesimally close to the top of that hill. Rockets are as close to perfect as they’re ever going to get. For a few more billion dollars we might be able to achieve a microscopic improvement in efficiency or reliability, but to make any game-changing improvements is not merely expensive; it’s a physical impossibility.’

…you can tell the abductees are lying or delusional because their descriptions of the aliens and their craft are always so unimaginative.

[space] The Hunt for Extraterrestrial Life Gets Weird … ‘For instance, Leitner said, we can send rovers to Mars carrying antibodies that detect traces of chemicals and bacteria that would indicate life. But because we can only make antibodies to known substances, this method will be limited to finding Earth-like life. “When we try to find a definition for life, in most cases, such a definition is more a summary of the specific properties of terrestrial life,” Leitner said. Because life on Earth requires water, most of the search for extraterrestrial life thus far has focused on the “habitable zone,” or the relatively narrow region around a star where liquid water could exist.’
[moon] To the Moon – with extreme engineering … a look at the story behind The Lunar Orbiter programme – a series of missions which mapped the moon’s surface before the Apollo landings … ‘The Lunar Orbiter astonishes even today. It had to take pictures, scan and develop the film on board, and broadcast it successfully back to earth. Naturally, the orbiter had to provide its own power, orient itself without intervention from ground control, and maintain precise temperature conditions and air pressure for the film processing, and protect itself from solar radiation and cosmic rays – all within severe size and weight constraints. This was far beyond the capabilities of the newest spy satellites, which back then returned the film to earth in a canister, retrieved by a specially kitted-out plane. The Orbiter challenge was the Apollo challenge in miniature.’
