Editor’s note – Bruce Dorminey, science journalist and author of Distant Wanderers: The search for Planets beyond the Solar System, is a lifelong proponent of lunar exploration.

Newt Gingrich certainly has his own political motives for suddenly deciding that now is the time to see that the decades-long dream of a lunar base finally makes it to fruition. But in addressing the issue of the U.S.’ future role in space, he arguably gave the most informed answer of anyone on stage at Thursday night’s Republican presidential debate in Jacksonville, Florida.

Mitt Romney’s measured response of first consulting with an interdisciplinary group of academics, captains of industry and the military, seemed to leave out NASA itself. But he was right in acknowledging that whatever the country’s next move in manned spaceflight might be, it should be tempered with some realistic rate of commercial and industrial return on America’s investment.

Gingrich seems better versed in the hardware and specifics of what’s needed for a manned return to the moon. But Romney’s admonition to Gingrich about making politically-expedient campaign promises simply to placate Florida’s Spacecoast also rings true.

While it’s heartening that America’s future role in space is being discussed in such high profile public forums, the last thing the U.S. needs is for a presidential candidate to wantonly raise the issue of finally realizing the dream of a manned lunar base in a cynical attempt to lure Florida voters in the space industry.

But given the current level of private space entrepreneurship, Romney’s own admonition that a lunar base would likely cost hundreds of billions of dollars seems a bit out of touch.
While it’s true that the international space station turned into a $100 billion financial behemoth, Gingrich’s ideas about adapting existing Atlas V launcher technology for a return manned trip to the moon sounds interesting, if not altogether feasible.

And he struck the right note when he acknowledged the need for entrepreneurial involvement from the get-go. A public-private partnership, with emphasis on commercial technology spin-offs, might be the needed tonic to restart a serious lunar effort.

A few $50 million prizes for Moon-minded, space entrepreneurs would go a long way in jumpstarting innovation while bringing down costs.

This whole manned lunar colony issue is likely to be largely forgotten after next Tuesday’s Florida primary, but some version of it will come up again at this summer’s political conventions and again in the general election debates next Fall.

Let’s just hope that when it does, it prompts a national discussion on NASA’s role in the 21st century; and how in these financially-strapped times, the U.S. can mount a manned mission back to the Moon, to an asteroid or even on to Mars in a realistic way.

There also needs to be a serious rethink of how NASA selects and then funds its missions. As any science journalist can attest, too often whole NASA missions are scrapped only months before launch; or launches are rescheduled so many times that the space agency begins to lose credibility with its own proponents. Just who’s to ultimately blame for the current state of affairs is hard to pinpoint. But serious astronomers and space researchers can hardly be thrilled about how such projects are currently funded and implemented.

Unfortunately, the general public is largely out of the loop when it comes to understanding the vagaries of NASA funding. The public’s limited exposure to national space policy nowadays mostly comes in the form of politicians on the campaign stump. There, political candidates use the same hackneyed catchphrases about exploring our “final frontier” just a little too often to evoke any real goosebumps.

But if the U.S. is to maintain its national identity as the world’s premier technological power, it needs to make sure that space is part of that equation. The byproducts of its dot.com generation and social media gurus are a marvel. But a Twitter from a South Pole lunar base would inspire the world.

Newt Promises a Moon Base by 2020

US Republican presidential candidate Newt Gingrich campaigned in Florida on Wednesday, and made some audacious claims if he would become President of the United States: “By the end of my second term we will have the first permanent base on the Moon and it will be American,” Gingrich said.

He also said that near-Earth space would be busy with launches by that same time frame – with “five or eight” launches a day, for space tourism and manufacturing, and that a new propulsion system would allow astronauts to get to Mars quickly and efficiently. The Space Coast crowd was captivated.

But how Gingrich would convince a future Congress to go along with what certainly would be an expensive proposition? President Obama couldn’t even convince Congress to give NASA an extra $6 billion over five years, and instead NASA’s budget has remained flat, without the big boost in technology development and science the current President was hoping for.

At a later space industry round-table discussion with Gingrich, one person commented that there are “no true space advocates in Congress, just members protecting their NASA centers and space pork.” Gingrich replied: “A good president doesn’t negotiate with Congress. He negotiates with the people, then the people negotiate with Congress.”

Even though Gingrich appears to support NASA, during the earlier rally, he also possibly indicated that he might cut NASA’s budget, saying he thinks NASA should become “lean and aggressive,” and less bureaucratic.

The former Speaker of the House of Representatives said he would support tax-free prizes, devoting 10% of NASA’s budget for entrepreneurial prizes of the kind that spurred Charles Lindbergh’s flight across the Atlantic (even though the current Congress nixed a recent similar proposal for NASA’s Office of Technology), and definitely outlined a nationalistic, US-only vision for space exploration, saying “we clearly have the capacity that Chinese and the Russians will never come anywhere close to us,” and “I accept the charge that I am an American, and Americans are instinctively grandiose, because we believe in a bigger future.”

Gingrich’s biggest Republican opponent at the moment is Mitt Romney, and Romney has ridiculed Gingrich for his Moon base plans. Gingrich even referenced a previous idea he had as “weird.”

“At one point early in my career I introduced the Northwest Ordinance in Space,” Gingrich said, where once there were “13,000 Americans living on the moon, they could petition to become a state.”

Reports from Florida say that Romney will unveil his plans for NASA later this week. The Republican Primary in Florida is on January 31.

Now as the theme from Arthur plays in your head you can enjoy this GIF animation of the ISS passing across the face of a daytime Moon, photographed by Alan Friedman from his location in upstate New York.

I know it’s crazy, but it’s true.

Alan captured these images at 10:30 a.m. EST back on September 2, 2007, and slowed down the animation a bit; in real-time the event lasted less than half a second. (Click the image for an even larger version.)

Atmospheric distortion creates the “wobbly” appearance of the Moon.

Alan Friedman is a talented photographer, printer (and avid vintage hat collector) living in Buffalo, NY. His images of the Sun in hydrogen alpha light are second-to-none and have been featured on many astronomy websites. When he’s not taking amazing photos of objects in the sky he creates beautiful hand-silkscreened greeting cards at his company Great Arrow Graphics.

NOTE: Although this article previously stated that the images were taken Jan. 12, 2012, they were actually captured in September 2007 and re-posted on Jan. 13 of this year. Alan states that he’s since learned how to judge exposure so the ISS doesn’t appear as a streak, but personally he likes (as do I) how this one came out.

Let’s see… September 2007… that would have been Expedition 15!

America’s Youth Christen NASA’s Twin New Lunar Craft – Ebb & Flow

A classroom of America’s Youth from an elementary school in Bozeman, Montana submitted the stellar winning entry in NASA’s nationwide student essay contest to rename the twin GRAIL lunar probes that just achieved orbit around our Moon on New Year’s Eve and New Year’s Day 2012

“Ebb” & “Flow” – are the dynamic duo’s official new names and were selected because they clearly illuminate the science goals of the gravity mapping spacecraft and how the Moon’s influence mightily affects Earth every day in a manner that’s easy for everyone to understand.

“The 28 students of Nina DiMauro’s class at the Emily Dickinson Elementary School have really hit the nail on the head,” said GRAIL principal investigator Prof. Maria Zuber of the Massachusetts Institute of Technology in Cambridge, Mass.

“We asked the youth of America to assist us in getting better names.”

“We chose Ebb and Flow because it’s the daily example of how the Moon’s gravity is working on the Earth,” said Zuber during a media briefing held today (Jan. 17) at NASA Headquarters in Washington, D.C. The terms ebb and flow refer to the movement of the tides on Earth due to the gravitational pull from the Moon.

“We were really impressed that the students drew their inspiration by researching GRAIL and its goal of measuring gravity. Ebb and Flow truly capture the spirit and excitement of our mission.”

Ebb and Flow are flying in tandem around Earth’s only natural satellite, the first time such a feat has ever been attempted.

As they fly over mountains, craters and basins on the Moon, the spaceships will move back and forth in orbit in an “ebb and flow” like response to the changing lunar gravity field and transmit radio signals to precisely measure the variations to within 1 micron, the width of a red blood cell.

The breakthrough science expected from the mirror image twins will provide unprecedented insight into what lurks mysteriously hidden beneath the surface of our nearest neighbor and deep into the interior.

The winning names from the 4th Graders of Emily Dickinson Elementary School were chosen from essays submitted by nearly 900 classrooms across America with over 11,000 students from 45 states, Puerto Rico and the District of Columbia, Zuber explained.

The students themselves announced “Ebb” and “Flow” in a dramaric live broadcast televised on NASA TV via Skype.

“We are so thrilled that our names were chosen and excited to share this with you. We can’t believe we won! We are so honored. Thank you!” said Ms. DiMauro as the very enthusiastic students spelled out the names by holding up the individual letters one-by-one on big placards from their classroom desks in Montana.

Watch the 4th Grade Kids spell the names in this video!

Until now the pair of probes went by the rather uninspiring monikers of GRAIL “A” and “B”. GRAIL stands for Gravity Recovery And Interior Laboratory.

The twin crafts’ new names were selected jointly by Prof. Zuber and Dr. Sally Ride, America’s first woman astronaut, and announced during today’s NASA briefing.


NASA’s naming competition was open to K-12 students who submitted pairs of names and a short essay to justified their suggestions.

“Ebb” and “Flow” (GRAIL A and GRAIL B) are the size of washing machines and were launched side by side atop a Delta II booster rocket on September 10, 2011 from Cape Canaveral, Florida.

They followed a circuitous 3.5 month low energy path to the Moon to minimize the fuel requirements and overall costs.

So far the probes have completed three burns of their main engines aimed at lowering and circularizing their initial highly elliptical orbits. The orbital period has also been reduced from 11.5 hours to just under 4 hours as of today.

“The science phase begins in early March,” said Zuber. At that time the twins will be flying in tandem at 55 kilometers (34 miles) altitude.

The GRAIL twins are also equipped with a very special camera dubbed MoonKAM (Moon Knowledge Acquired by Middle school students) whose purpose is to inspire kids to study science.

“GRAIL is NASA’s first planetary spacecraft mission carrying instruments entirely dedicated to education and public outreach,” explained Sally Ride. “Over 2100 classrooms have signed up so far to participate.”

Thousands of middle school students in grades five through eight will select target areas on the lunar surface and send requests for study to the GRAIL MoonKAM Mission Operations Center in San Diego which is managed by Dr. Ride in collaboration with undergraduate students at the University of California in San Diego.

By having their names selected, the 4th graders from Emily Dickinson Elementary have also won the prize to choose the first target on the Moon to photograph with the MoonKam cameras, said Ride.

Zuber notes that the first MoonKAM images will be snapped shortly after the 82 day science phase begins on March 8.

Who Owns Space History, the Public or the Astronauts?

The Apollo 13 checklist with Lovell's handwritten calculations. Image credit:

Former NASA astronaut Jim Lovell came under fire last week when he sold a personal memento from his tenure with the space agency at an auction – the 70-page checklist from the famous Apollo 13 mission that didn’t land on the Moon. The sale has reopened the ongoing debate over who owns NASA artifacts and photographs, the astronauts or the public.

In Lovell’s case, the checklist is so valuable because it contains Lovell’s hand written calculations he used to navigate the crippled Apollo 13 spacecraft after its oxygen tank exploded. That’s a pretty important piece of history for many collectors. Bids on the historic item surpassed $388,000.

But now NASA is questioning whether Lovell had the right to sell the item and profit from its sale. For now, the checklist – along with a lunar module identification plate and a hand controller from Apollo 9 sold by former astronaut Rusty Schweickart and a glove Al Shepard wore on the Moon on Apollo 14 sold at the same auction – is locked in a Heritage Auctions vault until the issue is resolved.

NASA administrator Charles Bolden released a statement saying that there have been “fundamental misunderstandings and unclear policies” regarding items astronauts took home from the Mercury, Gemini, Apollo and Skylab mission.

These “misunderstandings and unclear policies” aren’t new. Last summer, NASA filed a lawsuit against Apollo 14 astronaut Ed Mitchell after he tried to sell a 16mm video camera he used on the Moon. NASA claimed Mitchell was selling the camera illegally and sued the former astronaut for ownership rights. Mitchell countered that the camera would have been left on the Moon had he not brought it home. It’s been sitting in his personal safe since 1971.

Mitchell isn’t wrong in his self defense. In the 1960s and 1970s, NASA officials told the astronauts that they could keep certain equipment from the missions.

In 2002, former Flight Director Chris Kraft said that he approved the policy. Apollo astronauts were allowed to keep personal items that flew with them as well anything from the lunar landing module that would otherwise have been abandoned on the Moon. The astronaut had great freedom in choosing what they wanted to keep.

“It was generally accepted that the astronauts could bring back pieces of equipment or hardware from this spacecraft for a keepsake of these journeys,” Kraft wrote.

Since the end of the space race, collectors around the world have paid millions to own pieces of history themselves. NASA’s problem isn’t with these former astronauts keeping pieces of history for themselves, it’s when they sell these artifacts for personal gain that creates a problem.

Kraft’s 2002 letter doesn’t address whether or not astronauts have the right to sell their mementos. In its recent letter to the auction house, NASA insisted only the agency can approve such artifacts for sale.

Bolden said the ownership discussions will explore “all policy, legislative and other legal means” to resolve ownership issues “and ensure that appropriate artifacts are preserved and available for display to the American people.” The agency has agreed to work cooperatively with the astronauts to resolve what’s recently become a contentious issue.

It is a bit of a grey area. The astronauts did the work, they trained for difficult mission and went to the Moon. But NASA footed the bill, and American tax payers funded NASA. The space agency argues that artifacts from the Apollo era should be available to the public. Everyone should be able to view and experience these pieces of one of the nation’s historic achievements.

A Wrinkled Moon

Wrinkle Ridge South of Plato
Wrinkle ridges, like this one in the northern part of Mare Imbrium, were studied using telescopic observations, as early as the 1880's. Data from the Apollo era refined our understanding of these interesting features. More recently, data from the Lunar Reconnaissance Orbiter Camera is calling that understanding into question.

Wrinkle ridges have been seen on the surface of the Moon for over a century. Studies of these interesting features began as early as 1885, with telescopic photographs, and continued beyond the Apollo era, with satellite and lander observations. Scientists thought they understood them, but the latest images from the Lunar Reconnaissance Orbital Camera (LROC) suggest we may not know the whole story.

By definition, wrinkle ridges are narrow, steep-sided ridges that form predominantly in volcanic regions. They are very complex features, which can be either straight or curved, or even be braided and zig-zagged. Their width can be anything from less than 1 km to over 20 km. And their heights range from a few meters (say the height of an average room) to 300 meters (about the height of a 100-story sky scraper). They are also asymmetric, with one side of the ridge being higher than the other. Often, these things sit on top of a gentle swell in the landscape. Features like this have been found on a number of planets throughout the Solar System, including the Moon, Mars, Mercury, and Venus.

The earliest researchers of lunar wrinkle ridges saw them through telescopes. When looking at the terminator (the line between the dark side and the lit side of the Moon), the angle of the Sun causes spectacular shadows to highlight the topography, allowing these otherwise subtle features to be seen. Scientists in the late 19th century believed that these wrinkle ridges, which were found predominantly in the volcanic mare regions, formed when the cooling magma shrank. The chilled crust at the very top of this magma body was now too large, and wrinkles had to form to accommodate the difference. This process was often compared to the wrinkled skin of a shriveled apple, or the skin on our hands as we age.

The dawn of the space age introduced orbiting satellites, which circled the Moon collecting images that were more detailed than had been possible ever before. Data from the 1960’s the Lunar Orbiter (LO) program, whose mission was to photograph the Moon in preparation for the Apollo missions, showed many more of these wrinkle ridge features.

Some researchers felt the LO data pointed to a volcanic origin for wrinkle ridges. They saw lava flows emanating from the wrinkle ridges and embaying impact craters. They suggested that lava flowed to the surface along linear fractures that exploited zones of weakness in the lunar crust (presumably, these weaknesses formed when impacts created the basins that lunar mare occupy). Lava that extruded onto the surface formed the wrinkle ridge features, while magma that intruded below the surface formed the regional swell the ridges sit on.

The Apollo missions, however, were able to provide information about what was happening below the surface, with the Apollo Lunar Sounder Experiment (ALSE). Data collected over a wrinkle ridge in the southeastern portion of Mare Serenitatis showed that there was some kind of topographic structure beneath the thin mare layers in this area. This suggested that wrinkle ridges were the surface expressions of thrust faults in the underlying crust. This interpretation was appealing because it explained why some wrinkle ridges are found outside of mare areas.


Bulging Wrinkle Ridge in Tsiolkovskiy Mare
Wrinkle ridges are generally steep-sided, asymmetric structures, displaying complex braiding or zig-zag patterns. This wrinkle ridge, in the northern mare of Tsiolkovskiy crater, is very different. Described as "bulging", it has a gently curved uniform shape. It is also much smaller than the wrinkle ridges seen before. This unusual wrinkle ridge suggests we may not understand the formation of these features as well as we thought.

Later, studies of wrinkle-like features on Earth refined our understanding of how these features form. Now the thinking is that wrinkle ridges form by tectonic buckling of the mare areas and their surroundings. When mare lavas are extruded on the surface of the Moon, they fill up the impact basins in a series of basalt layers. The thinned crust left by the basin-forming process can’t support the weight of the mare, so the entire structure sags. The mare layer can become decoupled from the underlying regolith (the “soil” layer that impacts created between the time the basin was formed and when the first mare lavas extruded) and slide towards the sagging centre. As it does so, it bunches up in places where the decoupling is not complete. This creates a series of thrust faults at the base of the mare layer, which show up as wrinkle ridges at the surface. This decoupling process is more pronounced for thinner mare layers, which explains why we often see wrinkle ridges at the edges of a mare.

Recent findings from the Lunar Reconnaissance Orbiter Camera (LROC) may challenge this current understanding of wrinkle ridge formation. LROC images from the mare in Tsiolkovskiy crater have identified wrinkle ridges that are considerably different from the ones seen before. For one, these wrinkle ridges are not asymmetrical in profile, but have a uniformly curved shape. Also, they are much smaller, measuring less than 100 meters in width, as opposed to the 1-20 km widths seen for other wrinkle ridges.

It remains to be seen if these new wrinkle ridges will again change our understanding of how these enigmatic features form. The discovery of these particular ridges is so new that there is nothing yet published about them! Perhaps this image and others like it will help us learn more about these enigmatic features and answer questions such as: does this new wrinkle ridge represent the beginnings of their formation process and that all such ridges started out so small and symmetrical? Or maybe we’ll find that they are extrusions of particularly viscous lava, which have barely protruded above the surface along a linear fault.

Scientists plan to target this area for further data acquisition, because only more data from LRO and further research will help solve the mysteries of the wrinkled Moon.

“The moon looks the same from the ISS as it does on Earth. Only we see it rise and set again and again.”

ESA astronaut André Kuipers tweeted this message earlier today, accompanied by the wonderful photo above showing a distant Moon resting along Earth’s limb. The solar panels of the docked Soyuz TMA-03M spacecraft are seen in the foreground.

André arrived at the Space Station on December 23 along with Expedition 30 crewmates Oleg Kononeko and Don Pettit.

In addition to conducting over 45 experiments for ESA, NASA and JAXA during his five months in orbit, André’s PromISSe mission will help educate children about math, science, engineering, technology, and the benefits – and challenges – of working in space.

The program will also encourage the next generation of space explorers to stay fit with the second edition of the international fitness initiative Mission X: Train Like an Astronaut.

A medical doctor, André serves as flight engineer aboard the ISS and will be highly involved in docking procedures for the new Dragon (SpaceX) and Cygnus (Orbital Sciences) capsules as part of NASA’s next-generation commercial spaceflight program.

Has the International Space Station (ISS) secretly joined NASA’s newly arrived GRAIL lunar twins orbiting the Moon?

No – but you might think so gazing at these dazzling new images of the Moon and the ISS snapped by a NASA photographer yesterday (Jan. 4) operating from the Johnson Space Center in Houston, Texas.

Check out this remarkable series of NASA photos above and below showing the ISS and her crew of six humans crossing the face of Earth’s Moon above the skies over Houston, Texas. And see my shot below of the Moon near Jupiter – in conjunction- taken just after the two GRAIL spacecraft achieved lunar orbit on New Year’s weekend.

In the photo above, the ISS is visible at the upper left during the early evening of Jan. 4, and almost looks like it’s in orbit around the Moon. In fact the ISS is still circling about 248 miles (391 kilometers) above Earth with the multinational Expedition 30 crew of astronauts and cosmonauts hailing from the US, Russia and Holland.

The amazing photo here is a composite image showing the ISS transiting the Moon’s near side above Houston in the evening hours of Jan 4.

The ISS is the brightest object in the night sky and easily visible to the naked eye if it’s in sight.

With a pair of binoculars, it’s even possible to see some of the stations structure like the solar panels, truss segments and modules.

Check this NASA Website for ISS viewing in your area.

How many of you have witnessed a sighting of the ISS?

It’s a very cool experience !

NASA says that some especially good and long views of the ISS lasting up to 6 minutes may be possible in the central time zone on Friday, Jan 6 – depending on the weather and your location.

Missions that Weren’t: One-Way Mission to the Moon

The Apollo lunar landing module as it looked in 1963. Image credit: wired.com

[/caption]

When President Kennedy promised America a lunar landing in 1961, he effectively set the Moon as the finish line in the space race. In the wake of his speech, NASA began scrambling to find a way to reach the Moon in advance of the Soviet Union, which at the time held a commanding lead in space. Apollo, already on the drawing board as an Earth orbiting program, was revised to reflect the lunar goal and Gemini was established as the interim program.

The pieces were in place; all NASA needed was a way to get to the Moon. Against this pressing background, two men proposed a desperate and direct mission to get an American on the Moon as quickly as possible.

The proposal came from two Bell Aerosystems Company employees. John M. Cord was a Project Engineer in the Advanced Design Division and Leonard M. Seale was a psychologist in charge of the Human Factors Division. At the Institute of Aerospace Sciences in Los Angeles in 1962, the pair unveiled their “One-Way Manned Space Mission” proposal.

The plan called for a one-man spacecraft to follow a direct ascent path to the Moon. Ten feet wide and seven feet tall, the empty spacecraft weighed less than half the much smaller Mercury capsule. Inside, the astronaut would have enough water for 12 days, oxygen for 18 with a 12-day emergency reserve, a battery-powered suit and backpack, and all the tools and medical supplies he might need.

He would land on the Moon after a two-and-a-half day trip and have just under ten days to set up his habitat. As part of his payload, the astronaut would arrive with four cargo modules with pre-installed life support systems and a nuclear reactor to generate electrical power. Two mated modules would become his primary living quarters, while the others placed in caves or buried in rubble — a feature Cord and Seale assumed would dominate the lunar landscape — would provide a shelter from solar storms.

With his temporary home set up, he would wait a little over two years for another mission to come and collect him. Cord and Seale estimated that this mission could be launched as early as 1965, a year of expected minimal solar activity. Larger launch vehicles capable of sending the three-man Apollo spacecraft would be ready by 1967. The one-way spaceman would have a long but finite stay on the Moon.

This proposal was incredibly practical. Since the astronaut wouldn’t be launching from the lunar surface, he wouldn’t need to carry the necessary propellant. Since he would return to Earth in another spacecraft, his own spacecraft wouldn’t need a heavy heat shield or parachutes. The one-way mission was a light and efficient proposal.

But it was also dangerous. The proposal didn’t include any redundancies; the direct ascent path gave the astronaut no chance to abort his mission after launch. He would have to deal with any problems that arose knowing he wouldn’t be able to make a quick return home.

Luckily for the possible astronaut the proposal was never seriously considered. In July 1962, a few weeks after the one-way mission was proposed, NASA announced its selection of the more complicated but safer Lunar Orbit Rendezvous (LOR) mode for Apollo missions.
