The Moon's geology learned through gameplay

Would young people learn science better
if it were packaged in a videogame?

That's the question at the heart of the Selene project, originally funded by NASA and carried through a four-year grant from the NSF. Selene studies video game learning and the ways researchers can assess how effectively that learning takes place.

The Center for Educational Technologies at Wheeling Jesuit University created Selene as an online game to discover how organizations could best use video games to introduce important science concepts.

Selene challenges players to learn the major geologic processes scientists believe formed the modern Moon. Players create their own moon and then pepper it with impact craters and flood it with lava. It's a great opportunity for students to learn about lunar geology while helping researchers study some key videogame design principles. In addition, playing Selene offers a way to take part in the International Year of Astronomy 2009, a global celebration of astronomy and its contributions to society and culture, highlighted by the 400th anniversary of the first use of an astronomical telescope by Galileo Galilei.

CET's research project CyGaMEs uses Selene to introduce players ages 13-18 the Moon's geology and researchers track players' game-play to study how Selene helps players to pick up on that subject matter. Developers currently have the project aligned to National Science Standards and the Texas State Science Standards. Other states standards are currently being developed.

CET presents numerous opportunities for educators to become involved, including working on game design, development, collaborative research and utilizing the project with students.

The Center for Educational Technologies produced Selene to conduct its research. If you're a student between the ages of 13-18, we'd love to have you play. The game takes about an hour to complete, but you can spend more time after checking out Selene's various resources about the Moon. To play, though, you have to be enrolled by an adult recruiter to ensure parent/guardian consent for your participation.

If you're an adult who'd like to help out, click on the Recruiter button at left and help us find players to take part in the study. Being a recruiter is simple and doesn't involve a lot of paperwork. The whole process involves getting oral consent from a parent or guardian, then forwarding Selene registration access to your recruited players. It's that simple.

Join in this exciting venture and be a part of cutting-edge research sponsored by the National Science Foundation.

Orion on display in DC

NASA Dryden Flight Research Center escorts NASA's
first Orion full-stage abort flight test module

NASA showcased the Orion command module, Monday in a day-long public event on the National Mall in Washington. The full-size mockup of the Constellation CEV was parked on the Mall between 4th and 7th Streets, SW, in front of the National Air and Space Museum. Reporters attended a briefing Monday morning.

The spacecraft mockup is on its way from water testing at the Naval Surface Warfare Center's Carderock Division in Bethesda to open water testing in the Atlantic, off the coast of KSC.

The goal of the operation, dubbed the Post-landing Orion Recovery Test, or PORT, is to determine what kind of motions the astronaut crew can expect after landing, as well as conditions outside for the recovery team.

Orion is targeted to begin carrying humans to ISS no sooner than 2015 and to the moon in 2020.

A new chronology for the Moon and Mercury

Simone Marchi, et. al.

In this paper we present a new method for dating the surface of the Moon, obtained by modeling the incoming flux of impactors and converting it into a size distribution of resulting craters. We compare the results from this model with the standard chronology for the Moon showing their similarities and discrepancies. In particular, we find indications of a non-constant impactor flux in the last 500 Myr and also discuss the implications of our findings for the Late Heavy Bombardment hypothesis. We also show the potential of our model for accurate dating of other inner Solar System bodies, by applying it to Mercury.

EADS Astrium wants to build more ESA ATVs

Next step - ATVs that return Cargo

Les Mureaux - March 31 (Reuters) - Astrium, the space unit of aerospace group EADS, says it is seeking support to build two extra resupply vehicles worth 400 million euros for the International Space Station.

The first ATV (Automated Transfer Vehicle) Jules Verne docked with ISS last year and was a breakthrough for the European Space Agency.

"We have sent ESA an offer to build two extra ATVs," Alain Charmeau, head of Astrium Space Transportation, told reporters, adding he expected to get a response by the end of 2009.

ESA was not immediately available to comment.

Ministers from the 18-nation ESA agreed in November to develop a new version of the ATV that would return cargo from the space station to Earth without burning up in the atmosphere.

Description: It all started with the second person who created a lunar map. Naming features on the Moon has had a long and contentious history. The various lunar maps, sketches and images produced during the last four centuries show how difficult it can be to be accurate and consistent in lunar nomenclature. Amateur astronomer 'Lunar Mark' Tillotson talks about some of the major selenographers and the people who are honored with a lunar feature.

Bio: Mark Tillotson is an engineer and amateur astronomer living in Pennsylvania. He is interested in the Moon, the history of astronomy and science in general. Mark is the author of two blogs, Today in Astronomy and Lunar Mark, and created the Astronomy Compendium; a wiki-spaces site designed as a collection of information about the people, places and events that shaped the science of Astronomy into the form we know today. He is the Star Party coordinator at the Lehigh Valley Amateur Astronomical Society and a communications team member for IYA2009 US; posting updates on Facebook as IYA Cosmos and on Twitter as IYA.

Italian 14-19 year olds measure moon's distance

Last week, four Spanish students revealed how they had taken pictures of the curvature of the Earth by attaching a digital camera to a helium balloon and letting it go. When the British newspaper The Daily Telegraph reported the work, the story snowballed, attracting worldwide coverage.

Now a group of 30 Italian students from classes 1SD and 1SE at the Liceo Scientifico "A. Vallisneri" in Lucca, Italy have gone one better with an ingenious measurement of the distance to the moon.

The students analysed an mp3 recording of the conversation between Neil Armstrong on the surface and ground control in Houston in which he utters his famous "one small step" speech. The recording is available on the NASA website.

They noticed an echo on this recording in which sentences from Earth are retransmitted via Armstrong's helmet speaker through his microphone and back to Earth. They used the open source audio editing program Audacity to measure the echo's delay which turned out to be 2.620 secs and used this to work out the distance to the moon as 3.93 x 10^8 metres.

That's not bad given that the actual distance varies between 3.63 and 4.05 x10^8 metres.

The students then went on to measure the eccentricity of the moon's orbit using conversations recorded during the Apollo 17 mission, which was on the lunar surface for 300 hours.

They even estimated their errors using the Moon's ephemerides. Likely errors include delays caused by electronics and the time it took for the signals to be routed to the various antennae around the world that NASA used for communications.

Not bad for a group of 14-19 year olds.

Wieczorek: Moonface two-face

The man in the moon always presents us with the same mugshot, because the Earth's tides have locked the moon's spin to ours. But in a talk yesterday, Mark Wieczorek pointed out that not only did it not always have to be this way, but also that there is some evidence that the moon actually did swap its Earth-facing side at least once in the ancient past.

The work builds on a theoretical result in the 1970s from the University of Arizona's Jay Melosh, who showed that there were two equally stable ways in which the face of the moon could freeze toward Earth: the near side, and the far side. A glancing blow from a moderately big asteroid would be enough to do the job. Wieczorek, of the Institut de Physique du Globe de Paris, now shows that if that was the case, there would be a slight preponderance of big impacts on the moon's leading edge (marked 'apex' in the image here), since its orbiting velocity would be added to, rather than subtracted from, the impacting object. Lo and behold, he finds, the oldest impacts cluster around the moon's trailing face -- implying a flip-flop. "It's probably happened several times," he says. Most basin impacts would be big enough for the great switcheroo, but based on chronology, Wieczorek suggests that Smythii would be a likely candidate.

He says the process of a face switch could even start and stop temporary lunar dynamos -- which would be an interesting new mechanism for imprinting magnetic orientations onto lunar rocks.

Melosh was pleased that someone followed up on his theoretical idea, and says it needs to be tested on many of the Jovian and Saturnian satellites. "This suggests that this could be a common process with the other tidally locked satellites," he says.

Chairs: David Kring & David Draper

Jacobsen, Remo, Petaev & Sasselov: Hf-W Chronometry and the Timing of the Giant Moon-forming Impact on Earth [#2054] For Hf-W chronometry of the Earth-Moon system (EMS) there are currently two end member options: (i) the formation of the EMS at ~32 Myr or (ii) formation of 90% of the Earth in the first six Myr followed by a very late (~100 Myr) formation of the Moon.

Touboul, Kleine, Bourdon, Nyquist & Shih: New 142Nd Evidence for a Non-Chondritic Composition of the Moon [#2269] Here we present new Sm-Nd data for lunar rocks that are used to evaluate the significance of the 146Sm-142Nd systematics for constraining the timescale of lunar differentiation and the bulk Nd isotope composition of the Moon.

Elardo & Draper: Crystallization of a Lunar Magma Ocean: Preliminary Experimental Results [#1181] Though widely accepted, the lunar magma ocean hypothesis has never been fully tested experimentally. Presented here are the preliminary results of experiments conducted on a bulk Moon composition to simulate lunar magma ocean crystallization.

Pahlevan & Stevenson: Chemical Fractionation after the Moon-forming Giant Impact [#2392] We test the hypothesis that the lunar mantle is derived from the terrestrial mantle via liquid-vapor fractionation during the afterglow of the giant impact.

Zindler & Jacobsen: Isotopic Equilibration of Earth’s Mantle and the Moon Subsequent to the Giant Impact? [#2542] The striking oxygen, chromium, and tungsten isotopic similarities between the Earth’s mantle and the Moon are discussed and modeled with a 3-box model.

E.M. Parmentier: On the Scale of Lunar Mantle Overturn Following Magma Ocean Fractional Solidification: The Role for Multiple Scales of Convective Motion [#1781] Multiple scales of mantle overturn following magma ocean fractional solidification reconciles the magmatic evolution of the Moon many of its important geological and geophysical characteristics.

J. Longhi: Origin of the Magnesian Suite Cumulates [#2356] Melting calculations on various combinations of rock types formed in the lunar magma ocean suggest that highly magnesian olivine characteristic of magnesian suite cumulates ultimately derives from the earliest dunite cumulates of the magma ocean.

Grange, Nemchin, Pidgeon & Meyer: Early History of the Moon: Zircon Perspective [#1473] U-Pb ages of lunar zircons highlight new details in the early history of the Moon, providing a younger limit for the LMO crystallization and indicating that the impact history of the Moon is more complex than the accepted late period of bombardment.

H.V. Frey: Crustal Thickness Evidence for More Previously Unrecognized Large Lunar Basins [#1687] Crustal thickness model data reveal the presence of even more large lunar basins that were previously unrecognized. The total number of lunar basins >300 km diameter may exceed 150, more than three times that determined by photogeologic mapping alone.

Wieczorek & Le Feuvre: Did a Large Impact Reorient the Moon? [#1554] More impacts should occur on the Moon’s western hemisphere as a result of this body’s synchronous rotation. We show that there are more old basins located on the Moon’s eastern hemisphere, suggesting that a large impact reoriented the Moon by 180°.

Jolliff, Korotev, Zeigler & Prettyman: Connecting Lunar Meteorite Dhofar 961 to the South Pole-Aitken Basin Through Lunar Prospector Gamma-Ray Data [#2555] Lunar meteorite Dhofar 961, which contains mafic impact-melt components, is matched to locations within South Pole-Aitken Basin through the 5-degree Lunar Prospector gamma-ray data. Implications for a lower crustal provenance are discussed.

Cahill, Lucey & Wieczorek: The Composition of Lunar Central Peaks Relative to Lunar Samples [#1222] Here we place the modeled mineralogy of lunar impact crater central peaks in the context of the lunar sample collection.

Wingo & Cowing: Recovering High Resolution Lunar Orbiter Images from Analog Tape [#2517] Original FR-900 tape recorders have been refurbished to play, digitize, and store, the original highest resolution images of the Moon. This paper outlines the process and the initial results of our efforts.
