A time capsule of satellite imagery of the earth will become available to scientists this month.
On June 28, digital imagery from more than three decades ago will be released by the Alaska Satellite Facility at the University of Alaska Fairbanks Geophysical Institute, NASA’s processor and distributor for this type of data. The images reveal an unprecedented view of sea ice, waves, forests, glaciers and more.

“This morning the seismic tremor was down just a little bit from yesterday. We’re hoping it calms down before too long, but it might last for awhile.”
Alaska Science Forum: Spring is in the air and ice in Barrow
By molly [dot] rettig [at] gi [dot] alaska [dot] edu (Molly Rettig)
On the 5-mile snowmachine ride up to Point Barrow, we saw several fresh polar bear tracks the size of dinner plates, a pile of whalebones from last year, and a 3-foot-wide crack in the sea ice that could swallow a sled. The crack was created when an ice floe in the open water crashed into shore-fast ice.
Measuring the winds of space: UAF team prepares for 2014 launch
The sounding rocket released bright puffs of tri-methyl aluminum, which scientists track from the ground to study winds near the lower boundary of space. The streak on the bottom right is formed by chemicals that have been moved and distorted by winds and turbulence.

On a clear, cold night two winters ago in Fort Yukon, Carl Andersen watched a rocket he helped design pierce the upper atmosphere. He and three other scientists shot pictures as the rocket ejected bright puffs of chemicals in an inverted V formation more than 60 miles up.
“They were the brightest things in the sky,” Andersen said from his office at the University of Alaska Fairbanks.
Monitoring Alaska's volcanoes for 25 years
Twenty-five years of monitoring and studying Alaska’s volcanoes by the Alaska Volcano Observatory have improved global understanding of how volcanoes work and how to live safely with volcanic eruptions. Timely warnings from AVO throughout its 25-year history have helped reduce the impact of erupting volcanoes, protecting lives, property, and economic well-being.
Boreal forests focus of First Friday art show
The September leaves of boreal trees in Gail Priday’s backyard swirled in a mass of orange against the gray sky.
The image is now captured in Priday’s oil painting, called “Backyard,” which will be one of the many artworks featured in “Views of the Boreal Forest,” a First Friday art show.
