We left the moon 40 years ago today. Will we ever return?

It was forty years today (at 22:54:37 UT) that human beings left the moon for the last time. Miles O’Brien remembers Commander Gene Cernan’s last words from the moon, lofty, rehearsed and memorized: “as we leave the Moon at Taurus-Littrow, we leave as we came and, God willing, as we shall return: with peace and hope for all mankind.”

Fallen Astronaut figure on the Moon

NewImage

Seen above is the Fallen Astronaut, a tiny aluminum figurine that on August 1, 1971 the Apollo 15 crew placed on the Moon's surface with a plaque listing the names of 14 astronauts and cosmonauts who had died. Belgian artist Paul Van Hoeydonck created the figure and later took a ton of shit from NASA for making replicas that he intended to sell. The space agency felt the commercialization went against their original understanding with Van Hoeydonck. "Fallen Astronaut" (Wikipedia, via Weird Universe)

Report: Now that election's decided, NASA may announce new manned lunar mission

Space.com spoke to space policy expert John Logsdon, a professor emeritus at George Washington University, about rumors that NASA may soon unveil new manned moon missions.

"Plans have probably already been cleared with the Obama Administration but have been kept under wraps in case Republican candidate Mitt Romney won," according to Space.com.

As the Independent notes, these comments sync with remarks by NASA deputy chief Lori Garver at a conference in September. (via Jenny Winder)

Pink Floyd moon landing space jam, 1969: "Moonhead"

[Video Link]

A few weeks ago, I blogged about my new obsession with early to mid-era Pink Floyd oddities. Following the death of astronaut Neil Armstrong this weekend, the NYT Lede blog points to a special rarity: a moon landing jam session the band recorded at a BBC TV studio during the descent of Apollo 11, the first time human beings ever set foot on another world. David Gilmour in the Guardian:

It was a live broadcast, and there was a panel of scientists on one side of the studio, with us on the other. I was 23. The programming was a little looser in those days, and if a producer of a late-night programme felt like it, they would do something a bit off the wall. Funnily enough I’ve never really heard it since, but it is on YouTube. They were broadcasting the moon landing and they thought that to provide a bit of a break they would show us jamming. It was only about five minutes long. The song was called Moonhead — it’s a nice, atmospheric, spacey 12-bar blues.

How the Eagle Landed: Grumman Construction Log, and a message to space (Apollo 11)

On the anniversary of Apollo 11, Steve Jurvetson posted an amazing, never-before-seen series of space artifacts. He writes:

On July 20, 1969, Eagle landed on the moon. These are the handwritten notes from the Grumman engineers as they pushed to complete Lunar Module LM-5 in 1968. On the last page, they learn than this particular Lunar Module would be the one to bring the first humans to the moon.

The Grumman Engineering Log served not only as an engineering notebook but also as an intercom between the day and night shift – separate teams that needed to push the ball forward from where the other left off. So we are offered a rare peek into the concerns, uncertainties and conversations that might have otherwise been quietly undocumented.

"We are on the fucking moon" (video)

[Video Link] Yesterday was the anniversary of Apollo 11's landing on the moon in 1969, the first time humans ever set foot on another world. Today, we discover this long-lost footage and audio from that historic moment. (thanks, inkfumes!)

Lunar topography replicated in gorgeous fine art carvings

San Francisco-based artist Craig Dorety has a series of carvings that "represent segments of the moon's surface as found in the topograhical data from JAXA's Kayuga mission."

"Painstaking attention is paid to the relationship of crater groups in the composition of each carving," Craig explains. "Areas of special interest have a natural balance of crater to sea; rough to gentle in texture."

Gardening on the Moon

Frycook posted this fascinating video from the Apollo era on the BoingBoing Submitterator. The basic gist: Back in the day, NASA scientists tried exposing various crops—corn, lettuce, tobacco ... you know, the essentials—to moon dust. The plants weren't grown in the dust, exactly. Instead, it was scattered in their pots or rubbed on some of their leaves. In this study, the plants that were exposed seemed to grow faster than unexposed plants.

That's pretty interesting, so I dug around a little to find out more about these studies. Turns out, growing plants in lunar soil isn't quite as promising as the video makes it sound, but it's not a ridonculous idea, either. In 2010, scientists at the University of Florida published a review of all the Apollo-era research on this subject, which amounted to exactly three published studies. From that data, we can say that the plants weren't obviously affected in any seriously negative ways by their exposure to lunar soils—which is good—but we can't really say the plants grew better their terrestrial-only cousins, either.

In the end, and as recorded in the peer-reviewed scientific literature, there were only three published primary studies of seeds, seedlings, and plants grown in contact with lunar materials. In those three cases, small amounts of lunar material were used, and the plants were relatively large. In general, the dusting of plants or the mixing of lunar fines with other support media makes plant interaction with the lunar material a small part of the plant experience. At no point were plants actually grown in lunar samples in the way that one might imagine, with the entire root structure growing through and in constant association with a lunar soil. It is no accident that the wording of most of the titles of the studies, as well as the careful discussion within the papers, refers to growth “in contact with” lunar samples—not “in” lunar samples. With only a small portion of the roots, for example, interacting with the lunar materials, it is likely that plant responses to the lunar materials were, therefore, quite attenuated due to the lack of an extensive plant/lunar soil interface. Biophysical issues, such as root penetration of dry and variously hydrated lunar sample types, were completely unaddressed. Thus, the effects of actual growth within lunar soils were simply not a part of the plant studies of the Apollo era.

On the other hand, in 2008 scientists with the European Space Agency tried growing marigolds in a medium of crushed rock—basically the much-cheaper equivalent of growing plants in moon "soil". There's no indication that the marigolds did better than those grown in real dirt, but they did grow and they did survive (even without any added fertilizer), which could be indirect evidence in support of the Moon gardeners of the future.

Ring of Fire: 2012 annular eclipse video made from 700 individual photo frames

[Video Link]

Boing Boing reader Cory Poole is a 33-year-old math and science teacher at University Preparatory School in Redding, CA. He sends in this beautiful video of yesterday's annular solar eclipse, and says:

This is a 60 second time-lapse video made from 700 individual frames through a Coronado Solar Max 60 Double Stacked Hydrogen Alpha Solar Telescope. The pictures were shot in Redding, CA, which was directly in the annular eclipse path. The filter on the telescope allows you to see the chromosphere which is a layer that contains solar prominences. The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state.

Super Moon was, in fact, pretty super (big photo gallery)

The full "super Moon", scientifically known as a "perigee moon", rises over Los Angeles, California May 5, 2012. A "super Moon" lit up Saturday's night sky in a once-a-year cosmic show, overshadowing a meteor shower from remnants of Halley's Comet, the U.S. space agency NASA said. The Moon looked especially big and bright, because it reached its closest spot to Earth at the same time it was in its full phase, NASA said. Below, the full moon rises behind a mosque as birds fly in Amman.

More photos of the "super Moon" as seen around the world this weekend follow, below.

Moon boxes and mystery men

See the box in this photo? It's more interesting than it looks. This is a box that went to the Moon.

Astronauts used the boxes to collect and bring back to Earth nearly 50 pounds of moon rocks and soil ... Each of the boxes was machined from a single piece of aluminum, "seamless except for the lid opening, which had a metalized gasket that firmly sealed when closed."

The photo comes from the Y-12 National Security Complex in Oak Ridge, Tenn.—a research facility that participated in the Manhattan Project and later was involved in designing equipment for the Apollo Project. Journalist Frank Munger writes about Y-12 and other parts of the Oak Ridge National Laboratory for the Knoxville News Sentinel.

This photo, which he posted on his blog, is also interesting because nobody knows who the three guys in the photo are. Munger was hoping that Boingers might be able to offer some leads.

Whatever happened to Russia's Moon lander?

The United State won the race to put a man on the Moon. But we weren't the first to land anything on the Moon. That prize went to the Soviet Union, which successfully put Luna 2 on the surface of the Moon in 1959.

Their later missions were less successful and the USSR never made it past unmanned moon landers. Even some of those failed. Last week, NASA's Lunar Reconnaissance Orbiter spotted the remains of two of these Luna missions, still sitting on the Moon. At Vice, Amy Teitel talks about the Luna program and what NASA has learned about why it failed.


Luna 23 met a similar fate. Launched on October 28, 1974, it malfunctioned halfway through its mission and ended up crashing on the surface in the Mare Crisium (the Sea of Crisis in the northwest on the Earth-facing side). The spacecraft stayed in contact with Earth after its hard landing, but it couldn’t get a sample. Mission scientists expected the spacecraft had tipped over as a result of its landing, but without a way to image the moon at a high resolution, they weren’t able to confirm, and the mystery endured.

It turns out they were indeed right. The whole spacecraft is still on the surface, its ascent engine never fired, and high resolution image from LRO’s cameras show the spacecraft lying on its side.

The story of the Apollo 11 moon landing, as told through data (video)

[video link]

This data visualization of the Apollo 11 moon mission gathers social and technical data from the 1969 lunar landing in video form. The horizontal axis is an interactive timeline.

The horizontal axis is an interactive timeline. The vertical axis is divided into several sections, each corresponding to a data source. At the top, commentators are present in narratives from Digital Apollo and NASA technical debriefings. Just below are the members of ground control. The middle section is a log-scale graph stretching from Earth (~10E9 ft. away) to the Moon. Utterances from the landing CAPCOM, Duke, the command module pilot, Collins, the mission commander, Armstrong, and the lunar module pilot, Aldrin, are plotted on this graph. The graph is partially overlaid on a composite image of the lunar surface.

More about the data presented, and the story told, at the project's Vimeo page. The project comes from the MIT Laboratory for Automation, Robotics, and Society, and was directed by David Mindell. Via Maria Popova. As noted on Flowing Data, my only disappointment is that they didn't get to the "One small step for [a] man" part!
