Planetology | Article about planetology by The Free Dictionary

The Geology of Mars provides an excellent introduction to the field of comparative planetology and should be a welcome addition to the bookshelf of planetary scientists. Comparative Planetology Distance Learning Course Outline Lucey of the Hawaii Institute of Geophysics and Planetology in Honolulu and his colleagues find that the crater floor, sampled in several places, has a slightly higher abundance of titanium and a significantly high er abundance of iron than the lunar crust does. The contract is for the provision of assistance for the definition, development and testing of digital subsystem of the instrument NO developed by the Institute for Research in Astrophysics and Planetology (IRAP) for the Solar Mission Orbiter of the ESA. After long scrutiny of the data, there it was, a slow but steady wind, releasing about 1 kg of plasma every second into the outer magnetosphere: this corresponds to almost 90 tonnes every day,” Dandouras of the Research Institute in Astrophysics and Planetology in Toulouse, France, said. Here they introduce the field of planetology and present commentary on stunning out-of-this world images of Earth and its celestial neighbors from recent space probes. In addition, the principles behind propulsion systems, medical science and life support will be intertwined with basic research areas such as the structure of the galaxy, orbits, relativity and planetology. Exploiting GOCE data to the maximum, scientists from the Research Institute in Astrophysics and Planetology in France, the French space agency CNES, the Institute of Earth Physics of Paris and Delft University of Technology in the Netherlands, supported by ESA’s Earth Observation Support to Science Element, have been studying past measurements. Water in the small bodies of the solar system, comparative planetology and the search for life beyond the solar system, and growth of dust as the initial step toward planet formation comprise a small sample of the topics of individual chapters. The quality of these images from ChemCam is outstanding, and the mosaic image of the spectrometer analyses has been essential for scientific interpretation of the data,” said Sylvestre Maurice, Deputy Principal Investigator for ChemCam at France’s Research Institute in Astrophysics and Planetology (IRAP). Seeds continues to tackle such big topics as the scale of the cosmos, the sky and its cycles, the origins of modern astronomy, atmospheric telescopes, starlight and atoms, the sun, the family of stars, their formation and architecture and their deaths, neutron stars and black holes, the Milky Way and other galaxies, cosmology in the twenty-first century, the origin of the solar system, comparative planetology of the planets, meteorites, asteroids, comets, and the possibility that on other planets the residents are also asking “What are we? These results emphasise the importance of comparative planetology in modern planetary sciences: finding familiar geological features on alien worlds like Titan allows us to test the theories explaining their formation,” said Nicolas Altobelli, ESA’s Cassini-Huygens project scientist.

Unit 37: Short Talk – Planetology – 1-Language

Good morning everyone. My name is Professor Michael Andrews. On behalf of myself and my colleagues, I would like to welcome you to Extrasolar Planetology, which is a new class being offered by the Astronomy Department this year.

About twenty-five years ago, there was no solid proof that other planets existed beyond our solar system. Most astronomers at that time felt that planets had to be out there, but they could not see them or prove they were there. Why? Simply put, planets are small and space is vast. Imagine trying to see a pea with a telescope from a hundred miles away, and you’ll understand how hard it is to find planets that are light years distant.

Clearly, something changed, for we now have a class called Extrasolar Planetology. What changed? Well, mainly, instruments got better and sophisticated telescopes were put into space. As a result, astronomers began to find the proof that they had lacked before.

The very first good evidence for the existence of other planets came from observations of ‘wobbling’ stars. Using their high-tech instruments and space-based telescopes, astronomers found that some stars wobbled as they moved through space. What could be causing this the astronomers wondered? And then Eureka! The only likely explanation seemed to be that these stars were being affected by the gravity of unseen orbiting companions. In other words-planets!

And now, if you would please turn off the lights, I would like to show you some slides of a few of these wobbling stars.

USGS Flagstaff Science Campus – Public Page

FSC History

The United States Geological Survey (USGS) Flagstaff Science Campus (FSC) houses science centers and research teams of the USGS that have a diverse range of scientific expertise. The late Eugene Shoemaker established the Astrogeology Branch of the USGS in Flagstaff in 1963, as a research facility for the new science of planetary geology. Flagstaff’s clear air and high elevation made it a desirable location for telescope observations of the Moon and planets, and nearby Meteor Crater was a superb training ground for the Apollo astronauts. There and in the volcanic fields surrounding Flagstaff, astronauts tested equipment and were taught to look at the Moon through the eyes of a geologist.

While the initial focus of the FSC was lunar and planetary studies, other USGS groups began to migrate to the campus in the 1960s through the 1990s. Scientific collaboration among the various scientists located at the FSC provide one of the most unique USGS campuses in the country. The expertise of FSC scientists and collaboration opportunities provide the ability to address science issues related to water, ecosystems, climate and land-use change, energy and minerals, environmental health, and planetary exploration and study.

FSC staff provides outreach to other science organizations, schools, and to the general public. Scientists provide brown bag lectures on campus and other locations in Flagstaff. The public can take self-guided tours of FSC facilities and science displays. Also, FSC staff participates in Flagstaffs annual Festival of Science.

For more information about FSC outreach activities, please contact Greg Vaughan (gvaughan@usgs.gov, 928-556-7006)

The Flagstaff Remote Sensing Science Consortium (FRSSC, pronounced Frisk) includes scientists and other professionals at the USGS Flagstaff Science Campus (FSC) who develop and apply remote sensing techniques and methods in support of USGS science priorities and societal needs.

Infrasound Laboratory, University of Hawaii

At the Infrasound Laboratory of the University of Hawaii, we use very sensitive microphones to listen to low-frequency sounds in the atmosphere. These sounds, known asinfrasoundbecause they are too low in frequency to be audible to the human ear, can carry through the atmosphere for thousands of kilometers.

At ISLA our primary mission is to operate listening stations as part of the International Monitoring System of theComprehensive Nuclear-Test-Ban Treaty. We also conduct research into acoustic source processes, propagation, instrumentation, signal and array processing, and software development.

Mystery of Ceres's Bright Spots Grows

New data from NASA’s Dawn spacecraft suggest varied origins for tantalizing gleams on the dwarf planet’s surface

Not all of the puzzling bright spots on the dwarf planet Ceres are alike. The closest-yet images of the gleams, taken from 45,000 kilometres away, suggest that at least two of the spots look different from one another when seen in infrared wavelengths.

The Hubble Space Telescope spied many of the bright spots from afar years ago, but the observations from NASA’sDawn spacecraftwhich began looping around Ceres on March 6are the first at close range. The images were released on April 13 in Vienna, Austria, at a meeting of the European Geosciences Union.

Scientists say that the bright spots may be related to ice exposed at the bottom of impact craters or from some kind of active geology. They glimmer tantalizingly in a new full-colour map of Ceres, obtained in February but released at the conference. The map uses false colours to tease out slight differences on the otherwise dark surface of Ceres.

This is the first idea of what the surface looks like, said Martin Hoffmann, a Dawn scientist from the Max Planck Institute for Solar System Research in Gttingen, Germany.

Dawn is beginning to sharpen its view of the bright spots as it gets closer to Ceres. The new infrared images compare Spot 1, near Ceres’ equator, with a pair of bright spots collectively known as Spot 5. Some scientists have speculated that the latter could belinked to an icy plume.

Spot 1 appears darker in images from Dawn’s infrared spectrometer, said Federico Tosi, a Dawn scientist at the Institute for Space Astrophysics and Planetology and the Italian National Institute for Astrophysics in Rome. That suggests that the area is cooler than the rest of the dwarf planet’s surface, supporting the idea that the spot is made of ice.

But for some reason Spot 5the brightest feature seen on Dawndoes not show up in infrared images. One possibility is that we still dont have enough resolution to see it in the proper way, said Tosi.

Dawn has also shown that some parts of Ceres are pockmarked by impact craters, while other regions seem smooth. So far there seem to be fewer large craters on Ceres than expected, says the mission’s principal investigator, Christopher Russell of the University of California, Los Angeles.

Comparative Planetology – Teach Astronomy

Comparative Planetology

In the 1970s, space probes radically increased our data on other planets in our solar system from space probes. Researchers were able to use this information to compare and contrast the different planets, looking for processes that work universally across planets with similar conditions. According to this technique, called comparative planetology, we can learn more by looking for the unifying principles different planets share, rather than by studying each planet as an unrelated system.

The planets in our solar system all formed from essentially the same stuff, yet they are now strikingly different in appearance and surface composition. To understand how this differentiation occurred we must look at both external processes (such as the delivery of water by comets) and internal processes (such as volcanism). The comparison of greenhouse warming on Venus, Earth, and possibly Mars, is one example of a process that occurs in different levels on different worlds. The presence of life and liquid water is another example they are present on Earth, but our two closest neighbors, Venus and Mars, currently lack either. Nature has performed various experiments for us, placing planets of different sizes at different distances from the Sun. We can compare the results of the experiments to learn more about how planets work in general, and especially about how the Earth itself works. Life, just like volcanism, effects our planets atmosphere, chemistry, and surface. Studying other, simpler, systems can help us understand the Earth more completely.

There are some simple, general rules we can derive from this method that helps us understand planets. Here are some examples:

The tenets of comparative planetology are all based on simple physical principles related to gravity, chemistry, and the kinetic theory of matter. Since we have evidence that these physical properties are universal, its a good bet that these rules apply to planets beyond the solar system, too. The exciting idea that we can predict the properties of yet-undiscovered planets is an example of the long reach of the scientific method.

Hualalai geothermal study planned

The search for geothermal energy under the dormant Hualalai volcano is moving forward.

A University of Hawaii researcher has asked the state Board of Land and Natural Resources for a geothermal exploration permit to conduct a noninvasive geophysical study of the west rift zone of Hualalai, just north of Kailua-Kona.

The project is funded by the U.S. Department of Energy and the state Department of Land and Natural Resources, researcher Nicole Lautze, with the Hawaii Institute of Geophysics and Planetology, said in her application. She did not return a phone message left at her office by press time Monday.

The Land Board is scheduled to consider the application Friday. The meeting is held in Honolulu and begins at 9 a.m.

Lautze said in her application that the Hualalai exploration is the first exploration permit in what will be an overall effort referred to as the Geothermal Resources Exploration Plan for Hawaii.

Researchers plan to conduct their surveys on nine parcels of land, all zoned agriculture. Theyve gotten permission from the landowners, which are the state, Kamehameha Schools, Makalei Golf Club, the Queen Liliuokalani Trust and Palani Ranch.

Researchers will use a standard technique called magnetotelluric survey that maps the electrical conductivity of rocks at depths from several hundred feet to as much as 20,000 feet below the surface.

The vast majority of developed geothermal systems in the world are located in regions where water can flow naturally through the heated rock formations, Lautze said in her application. Being able to identify the subsurface heat source and fractured zones allows us to begin to address some of the problems of geothermal exploration and development.

The system uses antennas and electrodes to measure naturally occurring, very low frequency electromagnetic waves. The apparatus does not generate electrical signals or transmit energy, Lautze said.

The islands geothermal production is currently limited to one 38-megawatt power plant, Puna Geothermal Venture, outside Pahoa.

UH website makes groundwater research public

The Hawaii Institute for Geophysics and Planetology has developed a website to make data on groundwater and geothermal resources accessible to the public.

The objective for the website is to bring together UH research with data on groundwater and geothermal resources that is collected by the Hawaii Department of Land and Natural Resources (DLNR) and Department of Health (DOH), University of Hawaii at Mnoa Geochemist Donald Thomas said.

According to Thomas, groundwater data goes back 100 years or more and is not very accessible to the public. The website formats the past and current data that is more easily accessible for people who want to learn more about geothermal resources.

Ultimately what we would really like is to have a system were people can go in and understand more about the groundwater system, Thomas said.

He added the first phase of the Hawaii Groundwater and Geothermal Resource Center (HGGRC) website is to analyze the data to see how sources of groundwater have changed over time due to climate change or urban development and how they should be managed in the future.

Both the data and information on the website have been generated by Hawaii Institute of Geophysics and Planetology scientists since 2010.

The HGGRC website provides searchable map displays that show what is to come for groundwater and geothermal energy data.

Humuula GroundwaterResearch Project

One project connected to the website, the Humuula Groundwater Research Project, focuses on researching the groundwater resources on Hawaii Island.

The projects researchers will drill two holes on the grounds of the Phakuloa Training Area (PTA), in the center of the island, to depths of 6000 to 6500 feet from the surface. The goal is to reach the point where the fresh groundwater and the oceans salt water meet and take rock core samples for future scientific study.
