Check out the November 2014 Planetary Data System Release of Mars HiRISE images. This release covers orbit ranges 38,000—38,399.
TED (Technology, Entertainment, Design) talks spread ideas in the form of short, powerful presentations. Are you thinking of giving a TED-style talk? The American Geophysical Union’s Plainspoken Scientist blog has tips for anyone preparing to do a short public talk.
Do you need a planetary scientist, astronomer, heliophysicist, or earth scientist to speak to your group? The NASA Science Mission Directorate Scientist Speaker’s Bureau request form will generate a list of potential speakers based upon your request and enable you to contact them.
Want to learn more about the permanent darkness inside Mercury’s craters? Use the MESSENGER Water-Ice Data Exploration (WIDE) tool. The four views shown here were captured from the WIDE tool, and the evidence from the radar, topography, shadow, and temperature datasets all support the presence of water ice in this crater.
This high-resolution geological map of Vesta is derived from Dawn spacecraft data. Brown colors represent the oldest, most heavily cratered surface. Purple colors in the north and light blue represent terrains modified by the Veneneia and Rheasilvia impacts, respectively. Light purples and dark blue colors below the equator represent the interior of the Rheasilvia and Veneneia basins. Greens and yellows represent relatively young landslides or other downhill movement and crater impact materials, respectively. This map unifies 15 individual quadrangle maps and is a Mollweide projection, centered on 180 degrees longitude using the Dawn Claudia coordinate system.
Data gathered by U.S. government sensors and released to NASA for use by the science community reveal that small impact events are frequent and random. A map of these small impact events – known as fireballs or bolides – recently released by NASA shows the frequency and approximate energy released by bolide events detected from 1994 through 2013.
Comet Churyumov-Gerasimenko has been in the news a lot lately. How much do you know about comets? NASA’s Lunar and Planetary Science: Comets webpage has lots of resources including a fact sheet, FAQs, mission information, images, and more.
The deadline for submissions to the Humans in Space Art Video Challenge has been extended to Sunday, November 30. Submit a video of any style three minutes or less that explores the question “How will space, science, and technology benefit humanity?”
