The LPI-JSC Center for Lunar Science and Exploration has prepared a series of video simulations of impact cratering processes for classroom use. The videos explore how impactor size and velocity, as well as target gravity and temperature, affect the sizes and morphologies of impact craters. The videos can be run in real time from the website or, if users prefer, downloaded to their own computers.
United States Topo quadrangles are digital topographic maps produced by the National Geospatial Program of the US Geological Survey (USGS). Created in the familiar 7.5-minute quadrangle format like the legacy paper maps, US Topo maps support frequent updating, wide and fast public distribution, and basic, on-screen geographic analysis. US Topo maps are available for free Web download from the USGS Store.
The American Geophysical Union (AGU) is asking scientists to share their work and field locations by submitting a Postcard from the Field to the AGU’s new Tumblr site. Take a picture of your field site and submit it, along with a short, postcard-style note, and tag it as a “postcard from the field.”
The final episode of Cosmos: A Spacetime Odyssey aired last night. Senior Producer and Director of the original COSMOS series Geoff Haines-Stiles shares his thoughts and reactions about the remake and how it compares to the original.

The Khan Academy, a not-for-profit organization providing free world-class education online for anyone anywhere, offers math and science content including physics, cosmology and astronomy. The Khan Academy has also partnered with NASA, the Exploratorium and the California Academy of Sciences among others to bring additional content to students, parents and teachers.
JSC veterans Gary McCollum and Don Bogard share their memories of the development, construction, and operation of the Lunar Receiving Lab. The NASA Johnson Space Center Oral History Project Edited Oral History Transcript of the interview held on June 18, 2012, is available online.
The document Lunar Receiving Laboratory Project History (NASA/CR–2004–208938) by Susan Mangus and William Larsen provides additional information and details about the lab’s origins and history.
Astronomers using the Hubble Space Telescope have assembled a comprehensive picture of the evolving universe, and it is among the most colorful deep space images ever captured by the 24-year-old telescope. The image, from a new study called the Ultraviolet Coverage of the Hubble Ultra Deep Field, provides the missing link in star formation.
Did you know that Hawaii played a significant role as the Apollo astronauts prepared for their moon missions? The Pacific International Space Center for Exploration Systems (PISCES) recently posted some rare images of Apollo astronauts training in Hawaii.
