NASA's SDO Satellite Captures Venus Transit Approach. SDO is collecting images of one of the rarest predictable solar events: tthe transit of Venus across the face of the sun. This event happens in pairs eight years apart that are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117.
As a conservative Republican who very much understands the need to reduce and control our spending, it may seem strange that I understand and accept that climate change is impacting my home, state and country. It is beyond comprehension that my party would so adamantly avoid dealing with the fact that we now are facing historical events on such a regular basis that it is impacting our state and national budgets in the hundreds of billions of dollars annually. Why do we continue to miss the chance to address proactively the adverse impacts of our past and current actions? Why is it that we have not connected the dots between climate change and real life events that have occurred in our own backyards? Why do we find it acceptable to have massive damage to our university, and yet sit by and be satisfied with the hundreds of millions of dollars that are being spent locally to repair the damage?

Photos I took today of the Space Shuttle Enterprise atop the 747 Shuttle Carier Aircraft as they flew around New York City.
NASA's plans to fly Space Shuttle Enterprise atop the 747 Shuttle Carrier Aircraft over the boroughs of New York City sometime this week. After landing at JFK, the shuttle will be carried by barge to the Intrepid Sea, Air & Space Museum. This is really exciting news, I mean how often does one see a space shuttle atop a 747?!? Hopefully I'll capture some shots of the aircrafts as they flies around the city.

Discovery, the first orbiter retired from NASA's shuttle fleet, completed 39 missions, spent 365 days in space, orbited the Earth 5,830 times, and traveled 148,221,675 miles. NASA will transfer Discovery to the National Air and Space Museum to go on display. (REUTERS/Robert Markowitz/NASA/Handout)

The Obama administration decided on Friday to back a proposal to allow nearly 1,300 new oil and gas drilling wells in Utah’s Desolation Canyon region, impacting over 200,000 acres of wildlands. The sheer scope of the project, if approved, will have untold negative and permanent impacts on this wild region’s incredible beauty. (via nrdc)
Got a minute to help stop this? Send a message to the administration and the Department of Interior that they must stand strong in protecting wilderness lands like Desolation Canyon.

Ibn Battuta is one of history’s great explorers. He set out from his native Tangier in 1325, when he was just 21. By the time he returned home for good almost 30 years later, he had covered some 120,000 km and nearly every part of the Islamic world. What makes me so astonished is to read about this great scholars account of his visit to the Somali coastal capital Mogadishu in 1331. Here is a quote of his travels to Somalia where he paints a picture of an exotic, vibrant and rich nation which played a vital role in world trade:
Mogadishu is a very large town. The people are merchants and very rich. They own large herds of camels…and also sheep. Here they manufacture the textiles called after the name of the town; these are of superior quality and are exported to Egypt and other places.
Inspirational!
Egypt’s endangered Gazelles taken down by machines guns and pick-up trucks. Piece by piece, we’ll kill this planet yet…
“Egypt’s gazelle population has decreased consistently and drastically for the past four decades mainly due to two factors: unregulated hunting practices and habitat destruction. Three species of gazelle used to live across Egypt. The Arabian gazelle is thought to have completely disappeared, as the most recent footprints of this mammal were found in the 1930s in Wadi al-Arish at the border with Israel. The slender-horned gazelle’s population is difficult to estimate, but according to Omar Attum, professor of biology at Indiana University Southeast who closely studies Egypt’s gazelles, the number of slender-horned gazelles is likely no higher than a hundred. “Slender-horned gazelles have low population densities. There have been some records of them in Siwa recently, but I really worry as the revolution in Libya has made weapons more widely available in a very large and porous border area,” he explains, stressing that whenever there is an armed conflict anywhere in the world, wildlife is threatened. Richard Hoath, British naturalist and author of the book, “A Field Guide to the Mammals of Egypt,” explains that the population of slender-horned gazelles is limited to an area southwest of Fayoum. “This gazelle is strictly a desert species; it is able to survive without drinking water its entire life, provided it can feed on desert shrubs and bushes,” he explains animatedly.”

Day in the life of a GIS Analyst
An abbreviated version of a typical day involving the duties of a GIS Analyst and Developer. Or maybe it’s just me.
Hour 1
Arrive to work before the sun does. Grab some coffee, catch up on email. Peruse the latest ArcUser and ArcNews and look at how easy it all should be.
Hour 2
Crap, all the Arc licenses are in use. Send out mass email to all users asking if someone can free one up. Ok, you have a license. One of your SDE databases is down, a ticket to ESRI has been sent. Use an old slower SDE. Begin running a geoprocessing task on a couple million polygons.
Hour 3
More coffee. Discover some internal web applications are not working because that single SDE is down. Send out email to users notifying of situation. Development IDE of choice crashes or freezes a few times to remind you that you are a bad person.
Hour 4
ArcMap crashes in the middle of editing. Try again, crap, cashed again. Try this one more… forget it, no more editing, just use draw tools to make quick exhibits.
Hour 5
More coffee. Given a PDF map that came from a consultant and asked make changes. That’s it, just a PDF. You do things to make this happen that make you feel dirty.
Hour 6
Lunch time. Ninety-percent of solutions to GIS questions or development issues are found on web sites that are blocked as Social Media or Blogs. Twitter rant (vis smartphone). Check that geoprocessing task is still running.
Hour 7
Rush request for exhibit that needs data on the SDE that is down. That particular dataset can also be found on an external hard drive. The enclosure died last month. Pry open enclosure, rip out hard drive, pop open work pc and manually plug it in to extract the data. Cross your fingers that no one from IT department walks in as the internals of your gutted work machine are exposed.
Hour 8
Seriously reconsidering your life decisions.
Hour 9
Geoprocessing task failed around the 8-hour 5-minute mark with geometry errors. After 40 minutes is still cancelling itself. Go home and drink to forget.
Note: No actual analysis got done, as the failed geoprocessing task squashed that goal.

NASA and Japan released a significantly improved version of the most complete digital topographic map of Earth, produced with detailed measurements from NASA's Terra spacecraft.
The map, known as a global digital elevation model, was created from images collected by the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer, or ASTER, instrument aboard Terra. So-called stereo-pair images are produced by merging two slightly offset two-dimensional images to create the three-dimensional effect of depth. The first version of the map was released by NASA and Japan's Ministry of Economy, Trade and Industry (METI) in June 2009.
The improved version of the map adds 260,000 additional stereo-pair images to improve coverage. It features improved spatial resolution, increased horizontal and vertical accuracy, more realistic coverage over water bodies and the ability to identify lakes as small as 0.6 miles (1 kilometer) in diameter. The map is available online to users everywhere at no cost.
The ASTER data cover 99 percent of Earth's landmass and span from 83 degrees north latitude to 83 degrees south. Each elevation measurement point in the data is 98 feet (30 meters) apart.
NASA and METI are jointly contributing the data for the ASTER topographic map to the Group on Earth Observations, an international partnership headquartered at the World Meteorological Organization in Geneva, Switzerland, for use in its Global Earth Observation System of Systems. This "system of systems" is a collaborative, international effort to share and integrate Earth observation data from many different instruments and systems to help monitor and forecast global environmental changes.
ASTER is one of five instruments launched on Terra in 1999. ASTER acquires images from visible to thermal infrared wavelengths, with spatial resolutions ranging from about 50 to 300 feet (15 to 90 meters). A joint science team from the United States and Japan validates and calibrates the instrument and data products. The U.S. science team is located at JPL.
NASA, METI, Japan's Earth Remote Sensing Data Analysis Center (ERSDAC), and the U.S. Geological Survey validated the data, with support from the U.S. National Geospatial-Intelligence Agency and other collaborators. The data are distributed by NASA's Land Processes Distributed Active Archive Center at the U.S. Geological Survey's Earth Resources Observation and Science Center in Sioux Falls, S.D., and by ERSDAC in Tokyo.
Users of the new version of the ASTER data products are advised that while improved, the data still contain anomalies and artifacts that will affect its usefulness for certain applications.

NASA Operation IceBridge Returns to Antarctica

For the third consecutive October, NASA research aircraft are flying over Antarctica in search of clues about the health and dynamics of the frozen continent's massive ice sheets and shelves. Part of the NASA-funded IceBridge mission, planes carry instruments to measure the thickness of snow and ice, as well as the shape of the land andseafloor beneath the ice.
On October 5, 2011, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this clear view of the Antarctic Peninsula, the Larsen Ice Shelf, and the sea ice covered waters around the region. The Peninsula stands out as the raised terrain amidst the ice from the lower left to upper middle of the image.
On October 12, 2011, NASA’s DC-8 aircraft flew from Punta Arenas, Chile, across the Antarctic Peninsula and Weddell Sea, and back to Chile—making two 1,700-kilometer transects from east to west across the region. Several early flights in the 2011 campaign will take the team over sea ice near the Antarctic Peninsula before too much of it melts in the southern spring. Scientists are trying to understand why sea ice in the Southern Hemisphere is not following the steady decline of sea ice thickness and extent observed in the Arctic.
Operation IceBridge is designed to continue critical ice sheet measurements for the next few years between the end of the ICESat I mission and the launch of ICESat II in 2016. Researchers make instrumented flights to Greenland and the Arctic each March through May, and over Antarctica each October and November. Many flight lines retrace previous ICESat-1 tracks or future ICESat-2 tracks. Some also align with current observations made by the European Space Agency's CryoSat-2 satellite.
The overlapping flight lines and satellite tracks help scientists improve the accuracy of their data. Scientists are concerned about how quickly key glaciers and ice shelves are thinning. Better understanding this type of change is crucial to projecting impacts like sea-level rise.
