Three rockets are scheduled to launch from Poker Flat Research Range this winter. The launch window officially opens at twilight, Sunday, Feb. 27, and will remain open until Tuesday, March 22. During this time, a total of three rockets will be launched. Two will gather data on Earth's mesospheric dust layer, and the third will fly through the aurora, probing the auroral curtain to learn more about its structure. 
New information about the Martian terrain suggests the Red Planet's surface once had water. High levels of hematite, a mineral associated with liquid water on Earth, were discovered on Mars last year.

Polar bears have adapted to living in a dynamic sea ice habitat, but a variety of new threats jeopardize the future of these bears. Industrialization of their habitat, over-harvesting, and climate change are impacting polar bear numbers and threatening their success as the Arctic's top carnivore.
More than six million acres of Alaska were burned in wildfires throughout the summer of 2004. Smoke from those fires created unhealthy breathing conditions for residents spending time outside. However, many people may not be aware that on some smoky days, indoor air conditions also were

Daniel Monteith, assistant professor of anthropology at the University of Alaska Southeast, will discuss how the information found within caves continually revises experts' ideas about the geology and human history of Alaska.
