"A new NASA challenge is looking for evidence to support a theory that electromagnetic pulses (EMP) may precede an earthquake, potentially offering a warning to those in the quake's path. The "Quest for Quakes" two-week algorithm challenge seeks to develop new software codes or algorithms to search through data and identify electromagnetic pulses that may precede an earthquake. Some researchers have speculated such pulses originating from the ground near earthquake epicenters could signal the onset of some quakes. "Developing a reliable approach that can separate potential earthquake-induced electromagnetic pulses from the myriad of natural and anthropogenic sources has been a significant challenge," said Craig Dobson, program scientist at NASA Headquarters in Washington. "We look forward to seeing the innovative ideas from this competition and learning more about this controversial phenomenon.""
"Science-team members for NASA's Mars Reconnaissance Orbiter are soliciting help from the public to analyze exotic features near the south pole of Mars. By categorizing features visible in images from the orbiter's Context Camera (CTX), volunteers are using their own computers to help the team identify specific areas for even more detailed examination with the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera. HiRISE can reveal more detail than any other camera ever put into orbit around Mars. Planet Four: Terrains is on a new platform released by the Zooniverse, an organization that currently hosts 30 projects that enlist people worldwide to contribute to discoveries in fields ranging from astronomy to zoology. The new platform is designed to make it easier than ever for a researcher needing help with data analysis to set up a task to involve volunteers."
"A team of scientists participating in a radio astronomy summer school had the unexpected opportunity to observe a recently discovered near-Earth asteroid as it zipped past our planet on July 7. The observations were made using the combined power of the National Science Foundation's (NSF) Green Bank Telescope (GBT) in West Virginia and a radar transmitter at NASA's Deep Space Network in Goldstone, California. he observations were taken during a biennial summer school on single-dish radio astronomy sponsored jointly by the NRAO and NSF's Arecibo Observatory. This educational program provides graduate students, post-doctoral researchers, and experts in other fields of astronomy with both knowledge and practical experience of the techniques and applications of single-dish radio astronomy."
"Following more than a year of intense effort channelled into a 10 cm box, the first of ESA's student satellites to be released from the International Space Station has been accepted for launch. A standard CubeSat measuring 10 x 10 x 10 cm, AAUSat-5 has been designed and built by 30 students from the University of Aalborg in Denmark, backed by ESA's Education Office. It will be carried to the Station in August, where it will be despatched into space in conjunction with the mission of Danish ESA astronaut Andreas Mogensen. "The team will have their small CubeSat deployed into orbit from the International Space Station, the most gigantic space structure ever built," commented Piero Galeone of the ESA Education Office's Fly Your Satellite! venture."
"Teaching remote sensing? This web mapping application can be a very useful teaching tool. The web mapping application covers the whole planet, with mapping services that are updated daily with new Landsat 8 scenes. Access many band combinations and indices by hovering over the tools to the left of the map image and selecting among the following:
- Agriculture: Highlights agriculture in bright green. Bands 6,5,2
- Natural Color: Sharpened with 25m panchromatic band. Bands 4,3,2+8
- Color Infrared: Healthy vegetation is bright red. Bands 5,4,3
- SWIR (Short Wave Infrared): Highlights rock formations. Bands 7,6,4
- Geology: Highlights geologic features. Bands 7,4,2
- Bathymetric: Highlights underwater features. Bands 4,3,1
- Panchromatic: Panchromatic image at 15m. Band 8
- Vegetation Index: Normalized Difference Vegetation Index (NDVI). (Band5-Band4)/(Band5+Band4)
- Moisture Index: Normalized Difference Moisture Index (NDMI). (Band5-Band6)/(Band5+Band6)"
