What the Chinese Moon landing teaches us about American lunar orbiter

NASA’s Lunar Atmosphere and Dust Environment Explorer was watching as China's Chang'e 3 landed on the Moon. But the landing didn't register on any of LADEE's sensors. Why? The answer teaches us a lot about both the orbiter and the Moon itself.

How is China's lunar mission going? Here's a rover postcard from the moon.

China launches lunar probe

The China National Space Administration has launched Chang'e 3, a plutonium-powered lunar lander on-board a 185-foot-tall Long March 3B rocket. The lander is on a four-day trajectory for the lunar surface, and will brake and enter lunar orbit on December 6th. It is scheduled to land on December 14th, in the Bay of Rainbows (Sinus Iridum). The rover masses 140kg, with nuclear heaters to keep systems alive during the two-week-long lunar nights, and will use radar to probe the lunascape as it roves during its mission. It is also outfitted with high-resolution panoramic cameras and telescopes. The Chinese space program's stated goal is to establish a space-station and autonomous landers that can return to Earth with samples.

The hazards of Moon dust

Despite all the attention lavished on Moon dust, we still don't know what effect the stuff has on human lungs ... which is kind of a big deal, considering the fact that the dust has busted through every vacuum seal its ever faced. And eaten through layers of moon boots. Basically, you can imagine Moon dust as those tiny shards that get left on the floor when you break a glass and inevitably end up embedded in your foot four days later. At The New Yorker, Kate Green writes about efforts to better understand the effects of Moon dust on various materials and how engineers are trying to find new ways to control it before humans return to the lunar surface.

What the Moon would look like if it were the same distance from Earth as the International Space Station

The Moon is about 400,000 kilometers from Earth. The International Space Station is 1000 times closer to Earth. What would the Moon look like at 420 kilometers from Earth? YetiPC1 made a video visualization. Don't miss Yeti's other amusing video that shows how much the US national debt grows each day, in the form of gold bars getting dumped on a table.

NASA had Apollo-era plans to send humans to Mars and Venus

In an alternate universe — one where Americans had a LOT more enthusiasm for spending money on massive space projects than we've ever actually demonstrated — the 1970s and 1980s might have been the era of manned missions to Mars and Venus. Amy Shira Teitel writes about how this could have been possible, using only the now-antiquated technology that got us to the Moon and back.

The Moon's mysterious dust

I'd never seen this NASA photo of Apollo 17 astronaut Gene Cernan before. It was taken after one of his three moonwalks with crewmate Harrison Schmitt, though you could be forgiven for assuming that Cernan just came in from a shift at the coal mine rather than a jaunt across the surface of the Moon.

At the Life, Unbounded blog, Caleb Scharf writes about the Moon dust you can see clinging to Cernan, describing it as sticky, abrasive, and gunpowder-scented. It's also not something we totally understand yet — at least, we still have a lot to learn about how Moon dust behaves on the Moon. On September 6, NASA is launching a satellite to study this very phenomenon. One thing it might figure out: Whether electrically charged particles of Moon dust might form an extremely thin and vanishingly temporary "atmosphere" that hovers and falls over the Moon's surface.

The waters of the Moon

There is water on the Moon. We've known that since 2009 and we keep finding evidence of more of the stuff. That's not the really fascinating part about this article by Joseph Stromberg. Instead, there two really cool things that you should learn: 1) The water on the Moon probably came from Earth and 2) the water on the Earth probably came from outer space.

Sometimes, you misplace your Moon dust

The University of California, Berkeley recently found 20 vials of Moon dust in an archival warehouse. Apparently, these were all loaned research samples that should have been returned to NASA more than 40 years ago. This is not the only institution to suffer from the same problem. At least 12 states had (and then lost) collections of small Moon rocks. Minnesota found theirs last year in a display case at the state Veteran Services Building, crowded into a cluster of lesser memorabilia, including an 8th-place award in a shooting competition. It could happen to anybody.

Lunar Orbiter Image Recovery Project: how you can help save historic space data

The Lunar Orbiter Image Recovery Project (LOIRP) was started by Dennis Wingo and Keith Cowing in 2008. They obtained the original analog tape drives from lunar missions in the '60s, which were literally covered in dust in a farmer’s barn, and they also got their hands on a complete collection of Lunar Orbiter analog data tapes that held a full set of all images carried back to Earth by the five spacecraft that flew between 1966 and 67.

Amazing, historic stuff. But all of these old media formats are fragile, and preservation can be a long and tedious process.

Cowing and Wingo funded the archival effort themselves in the beginning, then secured some funding from NASA. But the NASA funding was modest, and has run out; the guys have been funding the project themselves, and they don't have the resources they need. They have exceeded the requirements of NASA’s funding, but just haven't been able to retrieve and digitally archive all of these irreplaceable historic space images—yet.

So they're crowdsourcing funds on RocketHub. They've raised about 1/3 of their goal at the time of this blog post, and they have only 5 days left.

Miles O'Brien did a "This week in Space" webshow episode about the project back in 2010; check it out above.

Below, more on the project from Cowing, who is also the guy behind NASAwatch.

A gravity map of the Moon

Gravity isn't uniform. Denser planets and objects in space — that is, things with more mass to them — experience a stronger pull of gravity. But even if you zoom in to the level of a single planet (or, in this case, our Moon), gravity isn't uniform all the way around. That's because the mass of the Moon isn't uniform, either. It varies, along with the topography. In some places, the Moon's crust is thicker. Those places have more mass, and thus, more gravitational pull.

This map, showing changes in density and gravity across the surface of the Moon, was made from data collected by Ebb and Flow — a matched set of NASA probes that mapped the Moon's gravitational field before being intentionally crashed on its surface last December. By measuring the gravitational field, these probes told us a lot about how the density of the Moon varies which, in turn, tells us a lot about topography.

You can read more about the probes (and see some videos they took of the lunar surface) at the NASA Visualization Explorer.

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.

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.
