Most of NASA’s Apollo program files are publicly available, in many cases digitized and accessible online. But there’s one picture from the Apollo 12 files that I’ve never been able to find much information about: a picture of a suit technician packing what is unmistakably a sandwich into Pete Conrad’s left leg pocket the morning he, Dick Gordon, and Al Bean launched to the Moon. Last November, I asked Dick Gordon about this scarcely documented space sandwich. [Read more...]
Most regular readers of Vintage Space will know that I’m obsessed with the Gemini Paraglider, the landing system that should have made splashdowns obsolete starting in the early 1960s but (to make a long story short) just couldn’t keep pace with Apollo. I’ve written about landings and the paraglider extensively in old blog posts: I’ve dealt with landings generally; discussed splashdowns as an imperfect landing method; talked about the paraglider’s inclusion in the Gemini program and the training vehicle astronauts flew to practice making paraglider landings; I’ve written about the paraglider’s cancellation from the Gemini program; it’s fate after Gemini; and even plans to use the paraglider to land the first stage of the Saturn V rocket. (And yes, there’s more, and I am working on bringing all of these pieces into something much larger.)
I brought my love of the paraglider to Scientific American this month. The latest episode of “It Happened in Space” gives a very brief overview of the Gemini paraglider landing system.
Orbital mechanics and the challenges of orbital rendezvous isn’t a simple thing to explain, particularly as a non-scientist breaking it down for other non-scientists. But it’s a central part of the Apollo mission profile, so it comes up a lot in my line of work. To illustrate the problem, I typically tell the story of Jim McDivitt trying to rendezvous with the Titan II’s upper stage during the first orbit of Gemini 4 – the story goes that when McDivitt’s pilot instincts kicked in the whole exercise went to hell. I asked McDivitt about that first failed rendezvous when I met him in Florida in November. He promptly and candidly told me that this story, which he’s heard many times, is bull hockey. I learned from the man himself what really happened on Gemini 4. I also learned that Jim McDivitt is, and I say this with the utmost respect, a total firecracker. [Read more...]
In all his official NASA portraits, Apollo 17 commander Gene Cernan looks stern. All the Apollo-era astronauts were photographed unsmiling, almost as though it would give tax paying Americans the sense that their national heroes took their roles deadly seriously every waking moment. But Cernan somehow looks more serious than most, and he looks like a man with a natural commanding physical presence. Last November I found myself in a bar with Gene Cernan, and even nearing 79 he absolutely possesses a quietly commanding presence I imagined. It’s incredible. Here’s what happened when I met the last man to walk on the Moon.
The past twelve months have been very good ones. I’ve met and worked with some incredible people, ventured into the (often awkward) world of podcasts and webcasts, and have read and written more than I ever did in grad school. Of the hundreds of articles I’ve written, a few stand out as favourites. And so, in no particular order, here are my top picks of 2012. These aren’t the big news items or the articles that got the most traffic. These are the ones that were fun to research and write, and the ones that taught me something new. [Read more...]
Regular readers of Vintage Space undoubtedly know that I love landing systems, particularly the creative ideas that were too complicated to gain traction in the 1960s. Among unrealized systems, my favourite has to be the Rogallo wing, the inflatable glider NASA tried to use as the runway landing system for Gemini. But there’s another that’s intrigued me for a while that I found while researching the Rogallo wing in NASA’s Washington archives and that’s the rotor reentry concept proposed for Apollo. It’s mysteriously absent from most program histories, but it seems to be making a comeback. NASA is once again looking at the rotor reentry as a way to land capsule-inspired spacecraft from the ISS. Read the full article over at Discovery News.
Regular readers are doubtless aware that I love the Rogallo paraglider wing. NASA had had no shortage of uses for this triangular, two-lobed sail design in the 1960s. It was the system that should have landed the Gemini spacecraft on a runway (if it had worked), it briefly was considered as the landing system for both Mercury and Apollo, and the U.S. Air Force was interested in the paraglider for its Manned Orbiting Laboratory program. But there were non-piloted applications of this technology as well. In the early 1960s, NASA studied how it might use the Rogallo wing to bring the first stage of a Saturn rocket to a runway landing for refurbishment and relaunch. I’ve given an overview of the Rogallo Saturn recovery system Discovery News.
The other day I was in a coffee shop, quietly writing and sharing a table with a woman also on a laptop. She caught me staring blankly out the window and asked what I was working on; apparently I looked troubled. I told her I was working on a new angle for my sixth or so Mars article that week. She seemed interested so I told her about Curiosity, the heritage technology that’s helped NASA make multiple successful Mars landings, and how the Sky Crane will open up a new future of exploration.
The idea that reusing technology saves money in spaceflight and that developing new technology now may cut costs on future missions caught her attention. She urged me to play up that angle because the amount of money NASA spends on these missions is stupid. “Curiosity,” she said, “cost half the nation’s defense budget.” That’s when I noticed her cross necklace and asked what kind of writer she is; turns out she’s a Christian motivational writer. That’s when I wished I had the figures on hand to illustrate just how little we spend on space exploration. But I didn’t so I quietly got back to work. But I did decided that I ought to write a blog post putting Curiosity into perspective so that the next time someone tells me NASA wastes money I can tell them how wrong they are. [Read more...]
In 1960, a year before Al Shepard made his ballistic flight on Freedom 7 and two years before John Glenn went into orbit on Friendship 7, NASA was already planning what to do after the Mercury program wrapped up. Mercury was limited by the capsule’s on board power source and fuel store to short orbital flights, so for its next program NASA was looking to lay a foundation in space exploration.
By 1962, a program with focused goals had emerged: NASA’s main goal would be to prove that astronauts could manoeuver their spacecraft in orbit to rendezvous and dock with another vehicle. On January 3 the new program was publicly christened Gemini, an interestingly fitting moniker. [Read more...]
On September 12, 1962, President Kennedy gave his famous speech at Rice University in Texas proclaiming that Americans take on lofty goals like landing a man on the Moon not because it is easy but because it is hard. It’s a speech that still resonates with spaceflight enthusiasts half a century later, often considered indicative of a time when NASA had clear goals and the necessary support to achieve them. But Kennedy’s own feelings about going to the Moon might have been different than the stirring words he said at Rice. In private conversations in the months and years that followed, he expressed worries over the cost of Apollo, raised questions regarding NASA’s commitment to a lunar program, and disappointment that the lunar landing wouldn’t happen within his presidential tenure.
