In Wired, photographer Roland Miller captures the decaying infrastructure of the early space race. “As launch pads were replaced, retrofitted or decommissioned, Miller was invited inside. By his estimate, 50 percent of the things he’s photographed no longer exist. ‘It’s not in NASA’s mission to conserve these sites,’ he says. ‘With shrinking budgets it’s an impossible thing to do.'”
“There’s not only last week’s deadly crash by Virgin Galactic, which hoped to launch widespread space tourism, or the unexpected explosion of a rocket headed toward the International Space Station. The United States also retired the space shuttle fleet in 2011. And…we now spend less on NASA — relative to the wealth of overall economy — than at any point in history.”
In very related news, and in the wake of Interstellar (which, on account of all the reasons I just mentioned, I haven’t seen yet), the Post‘s Zachary Goldfarb briefly surveys our current neglect of the space program. (Here’s what we’ve got planned at the moment.) “As recently as 2012, polling showed that more Americans than ever before thought that we were spending too little.”
On the 45th anniversary of the Apollo 11 landing, Phil Plait wonders what the hell happened to the Dream of Space in America. “Venturing into space is not just something we can do. It’s something we must do.”
And here’s your counterpoint: Creationist Ken Buck argues that space exploration is a boondoggle because aliens are going to Hell anyway. “Ham argued that ‘secularists are desperate to find life in outer space’ as a part of their ‘rebellion against God in a desperate attempt to supposedly prove evolution.'”
Erm, yeah. I would hope the John Olver rule is in effect if and when this fellow is inevitably queried about his views on television, against Bill Nye or Neil DeGrasse Tyson or somesuch.
Who knows what will happen in 2020 — for now, the scientists (if not the politicians) are saying that “the relationship between NASA and Roscosmos is good, it is healthy.” In any event, NASA has set up a 24-hour live-feed from the ISS. Hopefully, it will help keep things in perspective down here.
Also in space news, National Geographic makes the case for a “partial” space elevator, whereby ground launches would go into low-earth orbit to drop off their payloads. (See also this New Statesman article from August 2012.) “A space elevator untethered to Earth, with both of its ends hanging in space, might cut the costs of space travel to high orbit by 40 percent, researchers report.”
NASA announces 715 new planets found by the Kepler telescope, and that’s only from the first two years of data. “About 94 percent of the new alien worlds are smaller than Neptune, researchers said, further bolstering earlier Kepler observations that suggested the Milky Way galaxy abounds with rocky planets like Earth…four of the worlds are less than 2.5 times the size of Earth and reside in the ‘habitable zone,’ that just-right range of distances that could allow liquid water to exist on their surfaces.”
Via io9, Scientists at NASA’s JPL find the strongest evidence of currently extant water on Mars yet. “We still don’t have a smoking gun for existence of water…Although we’re not sure how this process would take place without water.”
Because of sequestration and other budget cuts, NASA is forced to cancel its advanced spacecraft power program, threatening future missions past the asteroid belt. “ASRGs had been under development by NASA for over a decade, and had been planned for use by 2016 in the next low-cost planetary exploration missions…Because of the limited cost cap imposed on these missions, they’re now essentially limited to the inner solar system. Missions with bigger budgets that could afford regular RTGs will be bottlenecked by the production rate of Plutonium to maybe once or twice per decade. Goodbye, outer planets.”
Hey neighbor: Astronomers find an Earth-like planet just next door in Alpha Centauri, the nearest star system to our sun. “Indeed, Alpha Centauri Bb is the first planet with an earth-like mass ever found orbiting a sun-like star.” That being said, prospects for life — or colonization — seem, for the time being, remote. “Unfortunately for any hope of finding life on this world, it orbits only about four million miles away…This would make Alpha Centauri B more than twenty times larger in the planet’s sky than the sun is here on earth…and more than 500 times brighter and hotter.”
James Fallows speaks with Space Adventures co-founder Eric Anderson on the coming age of space colonization. “One key to making all this happen is that we need to use the resources of space to help us colonize space…The near-Earth asteroids, which are very, very close to the Earth, are filled with resources that would be useful for people wanting to go to Mars, or anywhere else in the solar system. They contain precious resources like water, rocket fuel, strategic metals.”
Along the same lines, and from last June, a Dutch company called Mars One has a very specific timetable in place for Mars colonization. “Lansdorp plans to send another couple of adventurous astronauts to join the colony every two years, but the idea is that no one gets a return journey. This is a permanent base, a Plymouth Rock in an entirely new world that will begin the long, slow and painstaking process of terraforming it.” The first four colonists, set to leave Earth in 2023, will be chosen this year.
Update: So far, it seems, the Mars One project has received 40,000 applications.
Well, at least one branch of our government is well-funded enough to take on these sorts of projects, I guess. Too bad the research is classified and likely highly iffy. Consider, similarly, the two “other” Hubbles found lying around in a Pentagon warehouse last year. “[S]top and think about this for a moment. The Department of Defense has the kind of funding needed — hundred of millions to billions of dollars, presumably — to build not one, but two, Hubble-like optical telescopes and then never use them.”
Consider this a wake-up call. This is one more reason why we need to invest in our space program — because, right now, we are playing chicken with the universe. That deadly asteroid might not hit tomorrow, or even in 2106. But the danger is real. As author Larry Niven put it, “the dinosaurs became extinct because they didn’t have a space program. And if we become extinct because we don’t have a space program, it’ll serve us right!”
Data from Kepler’s Space Telescope suggests that an estimated 6% of red dwarf stars have planets in the habitable zone, meaning, statistically, we are basically surrounded by inhabitable worlds. “Our Sun is surrounded by a swarm of red dwarf stars. About 75 percent of the closest stars are red dwarfs.”
Popular Science previews the flight of NASA’s Sunjammer, set for launch in 2014. “The destination for Sunjammer is the Earth-Sun Lagrange Point 1, a gravitationally stable spot way out there between us and our nearest star…Sunjammer will be carrying the cremated remains of various individuals, including Star Trek creator Gene Roddenberry and his wife Majel Barrett Roddenberry.”
An auspicious site for New Rome: Seven hills on Mars are named after the fallen astronauts of Columbia. “Spirit would go on to spend several years exploring the Columbia Hills until, struggling in the Martian soil, it would finally cease to function in 2010. Which — striving and striving, until you can strive no more — seems an appropriate tribute to seven people who gave their lives so that the rest of us might forge ahead.”
Just re-reading The Forever War at the moment, so this seems very apropos. io9 looks into the recent possible breakthrough on a functioning warp drive. “Mathematically, the field equations predict that this is possible, but it remains to be seen if we could ever reduce this to practice.“
Of course, while mathematicians might have gotten around the “ridiculous amounts of energy required” problem, there’s now the new issue of ridiculous amounts of energy expended — in a lethal frontward cone. “When the Alcubierre-driven ship decelerates from superluminal speed, the particles its bubble has gathered are released in energetic outbursts. In the case of forward-facing particles the outburst can be very energetic — enough to destroy anyone at the destination directly in front of the ship. ‘Any people at the destination,’ the team’s paper concludes, ‘would be gamma ray and high energy particle blasted into oblivion due to the extreme blueshifts for [forward] region particles.'”
“‘The ticket price needs to be low enough that most people in advanced countries, in their mid-forties or something like that, could put together enough money to make the trip,’ he said, comparing the purchase to buying a house in California.”
If you’d prefer to stay within system instead, SpaceX founder Elon Musk sets the cost of a one-way ticket to Mars at $500,000. “‘Some money has to be spent on establishing a base on Mars. It’s about getting the basic fundamentals in place,’ Musk said. ‘That was true of the English colonies [in the Americas]; it took a significant expense to get things started. But once there are regular Mars flights, you can get the cost down to half a million dollars for someone to move to Mars. Then I think there are enough people who would buy that to have it be a reasonable business case.” Start saving up, y’all — Get there before the religious zealots, er, Pilgrims, move in. Update: More details on Musk’s proposal.
In the wake of Neil Armstrong’s passing, The New Statesman‘s Alex Hern makes the case for moving in the direction of a space elevator. The political argument aside, serious forays into space are clearly hindered by the prohibitive costs of leaving orbit more than anything else. If we are going to get serious about this, a space elevator is a technology that’s worth looking into. Right now, only Japan is on the case.
Commander Neil Armstrong, the pioneer who took the first step on extra-terrestrial soil and towards our ultimate destiny, 1930-2012. “The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet…our opportunities are unlimited.“
