State's Moon rock rescued from oblivion

North Carolina State University professor Christopher Brown holds North Carolina's long-neglected Apollo 17 lunar sample [Charlotte Observer].

It is the hardest proof of a peak of human achievement, far rarer than any gem and maybe worth $5 million or more.

It's also a drab little black pebble encased in a plastic ball and glued to a slightly kitschy early 1970s plaque. Which might help explain how the state's official moon rock ended up in a desk drawer at the Department of Commerce, then spent the past seven years in the custody of an N.C. State University professor who took it on occasional visits to school groups.

No longer. On Tuesday, the professor, Christopher Brown, brought the rock and other artifacts that it came with to the state Museum of Natural Sciences, where it is expected to go on display in a major new wing called the Nature Research Center when it opens in the fall of 2011.

"I've shown it to, who knows, hundreds of people," Brown told museum officials after handing over the rock. "You'll show it to thousands every day."

Joseph Gutheinz, a retired NASA investigator who since 2002 has led an informal project to locate the 370 or so lunar samples given to the states and other countries, said he was overjoyed to hear that North Carolina's had surfaced. But, he added, the museum needs to be careful.

A host of moon rocks have been stolen, from NASA itself in several cases, and a few have apparently traded hands for millions of dollars.

Some are now displayed under bulletproof glass with video cameras trained on them and guards nearby, said Gutheinz, a Houston lawyer who teaches classes in investigative techniques at the University of Phoenix. Over the years, he has assigned about 1,000 students to help locate the rocks.

"When people know where this moon rock is, it will become a target," Gutheinz said. "You want it on display, you want it shown. But if they don't create a secure display, it's like a bundle of money just sitting out there, and someone will make a play for it."

Radiation blanket claims utterly fantastic, without hard numbers

Notional habitat on the Moon shielded from radiation by Lunatex, developed under supervision of Dr. Warren Jaspers at North Carolina State University in Raleigh. The fabric-system as described in print purports to protect human life from the wide range of radiation hazards outside Earth's atmosphere and magnetic field. All reports so far, however, fail to mention the certain limitations of the fabric. (Specialty Fabrics Review)

For months, we've taken the quiet, modestly skeptical approach as to Dr. Warren Jaspers LUNAR-TEX, especially matter-of-fact news releases advertising a textile with super powers. Then, on Sunday (and, most peculiarly, just after a private discussion here about mitigating space radiation hazards) the LUNAR-TEX miracle surfaces again, following weeks with little mention anywhere.

Blanket protects lunar outposts
Specialty Fabrics Review

"Textile engineering students at North Carolina State University (NCSU) have the next manned moon landing covered with a blanket that protects lunar outposts from radiation while storing energy for astronauts’ use. The project, one of 10 finalists in the Revolutionary Aerospace Systems Concepts Academic Linkage competition, tackles one of NASA’s key concerns about moon missions that will likely last months at a time—cosmic rays and solar flares that make dangerous radiation hard to stop."

"The “lunar texshield” is made from a lightweight polymer composite with a layer of radiation shielding that deflects or absorbs radiation. The outer shield layer includes solar cells to generate electricity. The design is flexible, lightweight, has a large surface area, and is easy to transport and deploy. “We understand the properties associated with different textile materials,” says Dr. Warren Jasper, NCSU professor of textile engineering and project advisor. “That gives us unique insight on how to troubleshoot some of these issues.”"

To which we replied:

"As much as we admire NC State's engineers and proven science department, this is not the first time we have been casually informed of an astounding claim, without sufficient detail about how well it works.

"According to the National Academies, in "Managing Space Radiation in the New Era of Space Exploration (2008) [http://www.nap.org/catalog/12045.html] a round-trip manned expedition to Mars, for example, would result in each crew member exceeding NASA's present individually assessed lifetime probable risk of radiation exposure induced death (4%).

"A fabric mitigating this risk on the lunar surface is reasonable, but affording protection from such risk as effectively as does Earth's magnetic field and atmosphere is not reasonable, most especially the risk from cosmic rays at or above 100 MeV. (Ed. Probably more like 500 MeV to 10 GeV, though the "ceiling" and incidence of the highest-energy particles are not yet known, data collected since 1958 show the rate of infall of Galactic Cosmic Rays into the inner Solar System is 50 to 60 percent higher at solar minimum.)

Since reports of this fabric's usefulness have not touched on any detail regarding its certain limitations, we are understandibly skeptical. It begs clarification as to just how this fabric changes hard numbers on well-established risk probabilities. With such numbers, we're prepared to salute a revolutionary development, equal to shielding equal to 11 meters of regolith. But, without such numbers these claims made for Lunatex seem utterly fantastic."

But, that is, as they say, academic. The claims made on behalf of Dr. Jaspers are, indeed, "utterly fantastic." At face value, the reports about LUNAR-TEX might as well claim protection against space debris or meteor bombardment, or hail and lightning. In fact, those claims would be more "probable."

What we have in Dr. Jasper's development is an innovation in systems and materials that are "probably" a real mitigation against the full range of space radiation over spectrum and time. It's probably a real breakthrough, and one that might make round-trips to Mars using present acceleration capability less than life threatening. As such, it may be a real breakthrough.

But enough is enough.

More reports about the development of a panacea cannot go unchallenged. This one is really starting to bug us because space radiation is, as far as we can tell, one of the things that appears to be totally misunderstood or ignored by all parties in the far-flung public space policy debate, currently underway in the United States.

15 teams make it to the Finals of NASA's Lunar Design Challenge

Fifteen teams made it to the Finals of a NASA and National Institute of Aerospace (NIA) competition challenging university students to think about conditions astronauts will experience upon the renewal of extended human activity on the moon, and afterward to design projects that could become part of lunar exploration.

Engineering students won the right to compete against each other at the 2009 Revolutionary Aerospace Systems Concepts Academic Linkage, or RASC-AL Forum, in Cocoa Beach, June 1-4.

“The RASC-AL steering committee of NASA and industry experts was impressed by the creativity, ingenuity and thoughtfulness of this years student entries,” said Pat Troutman, senior systems analyst NASA Langley. “Next Generation engineers are going to be crucial in helping NASA get back to the moon, then to Mars and beyond.”

The five graduate student teams include University of Texas in Austin; University of Maryland, College Park; a joint effort from University of Florida in Gainesville and Arizona State University, Tempe; and two Georgia Tech groups that reside at NIA.

Ten undergraduate student teams made the cut, from the Colorado School of Mines in Golden; Arizona State; a combination of Penn State, Polytechnic Institute of NYU-Brooklyn and Georgia Tech of Atlanta; U. of Maryland; Clarkson U. in Potsdam, NY; University of Alabama in Huntsville; Virginia Tech, ; Worcester Polytechnic Institute; NC State; and a NC State team that resides at NIA.

The student teams submitted a summary of and an outreach plan for their proposed projects. Their work was based on one of four themes: outpost to settlement, initial lunar outpost, bringing the world along with virtual exploration and novel approaches to increase sample return from the moon.

The teams must submit a written report, prepare a poster and give an oral presentation at the RASC-AL forum. The steering committee will score the students’ work and award first and second prizes in undergraduate and graduate categories. To cover costs of travel, registration and incidentals each team receives $5,875.

“NIA is impressed by the quality of proposed design projects and we anticipate a highly competitive forum,” said Dr. Bernard Grossman, vice president of education and outreach at NIA. “RASC-AL is a great venue to identify todays university students grasp of engineering concepts.”

The June forum will give faculty and students the chance to meet with NASA and industry experts, introduce concepts and data from the competition into NASA exploration program planning, develop relationships that could lead to participation in other NASA student research programs and show the benefits of NASA-university-industry cooperation.

Raleigh's Team Stellar works toward prize

North Carolina State University Technician Online
August 21

N.C. State is traveling to the moon.

Or, rather, its designs are.

Graduate and undergraduate students and two professors are working with Team Stellar, a team of electrical, computer and aerospace engineers, to produce a rover that will land on the moon.

They are doing so through the Google Lunar X Prize, which is awarding $30 million to the winning team, of which there are 14.

The rover must land on the moon, travel 500 meters, and send high-definition video, a text message and an e-mail back to Earth.

There's only one snag in the project: funding.

Team Stellar still needs to raise $200,000 -- counting money, sponsorship and in-kind donations -- to keep the project going, according to Dick Dell, a member of the team and executive director of the Advanced Vehicle Research Center. The AVRC also worked on the self-navigating DARPA vehicle.

"The biggest challenge to the challenge is bringing the funding," Dell said, adding that outside resources must cover the cost of the project, which he predicted to lie in the $50 to $100 million range. "We have the technology, and we have the people there at N.C. State that can do it."

The rules
The high-definition video must stream everything from the rover's landing on the moon to its travel, according to Gordon Jeans, a member of Team Stellar and a senior in computer engineering.

According to Google's rules for the X-Prize challenge, the rover must complete a set of tasks, two of which include sending an e-mail and text message to Earth from the moon.

"That's kind of tongue-in-cheek for me," Jeans said, adding that Google will be the first to send such information back from the moon.

But before they even get to the moon, the team has got some work to do.

The team
The main team is composed of seven men, each of whom has a distinct role in ensuring that each aspect of the rover -- from what wheels to use to what technology will help transmit a text message -- is completed in time for the launch.

Andre Mazzoleni, a professor of engineering who works with the rover's engineering and design aspects, joined Team Stellar last spring.

Dell, he said, had found him through the work he was doing with the N.C. Space Grant. Since Mazzoleni was involved with NASA projects and rover design, he was a prime candidate for the position.

The team then looked toward Jeans.

"They wanted students who knew other students to get together people to work on the project," he said. "I didn't actually know about it until they approached me that summer."

Jeans, who worked with tanks during a 10-year stint in the army, said he knows about making vehicles that can stand conditions of extreme cold, heat and darkness -- conditions that the moon cycles through during every rotation.

Jeans also worked with Lego robotics, and Dell happened to be sitting through Jeans' presentation on that subject.

When the two met after the presentation, "one conversation led to another and we found out that we were both in love with space."

It's this knowledge about computers and engineering -- an education he got through both classes and experience with the army -- as well as a background in outer space exploration that he adds to the team.

Jeans submitted one of the initial designs for the rover. It was a simple design, he said, but would be able to navigate the surface of the moon. Its materials, he said, have to be chosen carefully.

"You have to use materials that can survive in those conditions," he said. "For example, silicone works great in heat but shatters in the cold. You have to have it operate on solar power and batteries, because batteries don't work well in the cold and you have a fixed amount of power."

Although Team Stellar is based primarily in Raleigh and on campus, there are people across the eastern states who are helping to move the project along.

The rover
Jeans' designs are not the only ones that have been submitted. Graduate students have been working over the summer to complete a functional design for the rover.

Undergraduates, many of whom have not been working on the project during the summer, will start their design this fall.

The team is focusing on the structural aspects.

"We're looking at multiple designs right now, and then we'll select the one that will end up working the best," Mazzoleni said. "The one the graduate students are working on is a little bit more mature. They've already focused in on a particular design."

This design is one in which the wheels can move independently, which, he said, should help it climb over rocks and maneuver around obstacles.

The students, including Jeans, will design and build several prototypes. Graduate students will build their prototype this semester and start testing it. Undergraduate students will work through next semester.

But the final product, which will use better, more durable and more costly material, won't be ready until the end of the upcoming spring semester. The working design must stand extreme heat and cold.

"It's a team effort," Mazzoleni said. "The ultimate rover might act be a combination of what Gordon's working on and what the graduate students are working on and what the undergraduate students are working on. We're going to learn from each of the prototypes and, from that, decide what goes in to the final version.

It's not like there's a winner."

The challenge
So the team has the resources and the support -- at a public meeting on Centennial campus Monday night, more than 200 people showed up to learn about and volunteer for the project.

At this point, it's the funding that is proving difficult to come by.

As per Google's rules for the X prize, only 10 percent of the team's funding can come from public funds. This rule, Jeans said, will ensure that the teams cut excess spending and only produce what is necessary to send a rover to the moon. Jeans also said it would encourage private companies to sponsor space travel to the moon, which he said will be the "next Antarctica," a place where researchers from many countries will do research and tests. No single entity will have ownership over it.

And although the team has no plans of stopping mid-project, it still must find funding from somewhere -- $200,000 of it. This funding can come in the form of donations, both monetary and of equipment like computers, and private sponsorship.

"All the teams are facing the same challenges," Dell said. "Only one of two of the teams have major funding. The rest of us haven't found a major sponsor yet."

Corporate sponsorship will make going to the moon easier, more cost efficient and more likely. Google's lists this as one of its goals, according to the Lunar X Prize Web site. A quicker and less costly ride to space will push companies to take an interest in space and the potentials it has for aiding some of Earth's energy crises.

The future
This project is not only a place to "put N.C. State on the map," as Jeans said, but also a place for practical application of in-class lectures.

"This is a perfect project to teach the process of engineering design because, in engineering design, you end up using a combination of learning all the scientific and engineering principles along with trying to use what you've learned in the classroom to create something new," Mazzoleni said.

"This is one more application of something in the department that students were very interested in and invested with."

Triangle team racing to moon

Raleigh News & Observer
Sunday, June 2, 2008

Tim Simmons
Staff Writer

In the category of audacious goals, a team of Triangle business leaders and N.C. State University faculty members has entered a worldwide contest to launch the first private rocket to the moon.

Houston, you have competition.

Sponsored by Google and the X Prize Foundation of California, the contest offers $30 million in prize money to teams that can meet the following challenge:

* Land an unmanned rover on the lunar surface.
* Travel at least 500 meters.
* Transmit video back to Earth.

But ultimately, this contest is about making the moon a permanent celestial outpost.

"The space race is on again," said Dick Dell Sr., director of Raleigh-based Advanced Vehicle Research Center and a key member of the moon launch team. "There is going to be a huge rush toward commercialization this time."

Almost four decades after man first landed on the moon, some will no doubt question the need for such a contest.

But the rules of the game are different this time. The X Prize Foundation, which offers huge sums of money to spur innovation in a variety of fields, envisions a day when large solar panels built on the moon are used to power entire cities on Earth.

It sees the moon as an extension of our reach, a launchpad for further exploration, a place where humans keep a permanent presence.

But first, you need to get there without government help.

Earth comes first

Dell was involved in supporting another futuristic endeavor -- building cars that compete in driverless races -- when he learned of the lunar competition.

The leader of the Grand Challenge driving team, Grayson Randall of Insight Technologies in Morrisville, was interested.

So was Andre Mazzoleni, a professor at NCSU who teaches orbital mechanics and space system design. William Edmonson, who teaches electrical and computer engineering at N.C. State, also wanted in. So did others.

By late 2007, TeamSTELLAR filed its application to launch a rocket to the moon. Its entry was accepted May 23, making it one of 14 teams cleared to compete.

Like Team Stellar, some of the groups have universities as partners.

The group known as Astrobotic Technology, for example, is a combined effort led by Carnegie Mellon University, The University of Arizona and Raytheon, a defense company.

But many of the teams are coalitions of private firms that want to pioneer private space travel. To underscore that point, 90 percent of a team's money must come from private sources, a rule intended to drive cost efficiencies.

The rules allow teams to hire a private launch company to take them into Earth orbit -- and there are many now, thanks to the needs of weather satellites and Global Positioning System satellites and a host of Earth-imaging products.

But it will take another set of rockets to launch from Earth orbit to lunar orbit, and still another set of rockets to drop out of the lunar orbit and land a rover.

Travel, video and just creating a craft that can survive extreme lunar climates -- temperatures can swing 450 degrees in a day -- keep the challenges coming.

But of all the tasks in front of Team Stellar, it is not the science that most worries Randall.

"We understand the technology," Randall said. "The first question is, where are we going to get the money we need?"

Investment and return

The answer brings the contest back to its entrepreneurial roots.

Any team that launches a rocket will spend far more than the $20 million set aside for the first-place winner. Dell predicts a final tab of $50 million to $100 million for the Team Stellar design. Raising that kind of money will depend on old-school marketing.

Small teams of NCSU students will handle some parts of the project, but the team still has holes to fill that will require private companies with specific technical expertise.Those companies could be asked to provide money as well as a specific skill, Dell said.

Others will be asked to sponsor the launch in return for publicity.

And potential investors will be told that $1 million plowed into the first private moon launch could return tens of millions.

Team Stellar members are convinced of that, pointing to the Ansari X Prize competition as proof.
In 2004, aerospace designer Burt Rutan and Microsoft co-founder Paul Allen won $10 million by becoming the first private group to carry three people into a low-space orbit.

Allen spent far more than $10 million, but within months the team signed a multimillion-dollar contract with a space tourism company.

Of course, that meant 25 other teams in the race got no immediate payback. And that's what will happen in the lunar competition for those who flop.

But space travel in general will push forward at a fraction of what it would cost a government agency -- a big goal of the contest.

Experiments and prizes

The idea of reaching air and space travel milestones with the lure of a prize is hardly new.

The idea was fairly common in the early 1900s, echoing a theme explored by author Jules Verne when the fictional Phileas Fogg bet he could travel around the world in 80 days.

When Charles Lindbergh flew nonstop from New York to Paris in 1927, he was spurred on by a $25,000 prize offered by French businessman Raymond Ortieg.

His efforts and others caused a huge increase in air travel that is seen as the catalyst for today's airline industry.

Aviation experts aren't sure what will happen once the first private moon launch succeeds.
But they are sure it will change the calculus of space travel.

The United States and other countries plan to return to the moon, but that could be more than a decade from now.

The deadline for the private competition is 2012. Those who compete will be first in line when the government needs subcontractors for its efforts.

"The only thing that has been profitable in space so far is some transportation and communications," said Bob Dickman, executive director of the American Institute of Aeronautics and Astronautics in Reston, Va.

"What this prize will do is send a message that NASA is not the only way to reach the moon," Dickman added. "Who knows where that will lead us?"

NCSU's Mazzoleni looks backward to answer the same question.

"When European explorers set out for the Americas, did they know what they would find?" he asked. "Was it important that they try?"

Minton wins 2008 Kuiper Memorial Award

Science Centric

David A. Minton, a third-year planetary sciences graduate student, will receive the 2008 Kuiper Memorial Award. The award is presented to University of Arizona students in the field of planetary sciences who have excelled in academic work and research.

'David is smart, enthusiastic, imaginative and hard working,' planetary sciences professor Renu Malhotra, Minton's graduate adviser, said. 'He has a genuine enthusiasm for planetary science, has strong technical skills and plunges into research projects with great energy.'

Minton enrolled in the UA's planetary sciences department in 2005, after graduate work at the University of Maryland and earning a degree in aerospace engineering at North Carolina State University. At North Carolina State, Minton led teams that designed a wind-powered Mars rover called Tumbleweed and a Mars climate orbiter with deployable balloons.

Minton is currently publishing an innovative analysis of small planetary bodies that resemble 'sand piles.' This work, which is a generalization of centuries-old mathematical theories, may provide an explanation for the 'flying saucer' appearance of objects like two of Saturn's satellites, Atlas and Pan.

Minton's paper will appear in the international planetary science journal Icarus.
