The Alaska Satellite Facility will celebrate its 25th anniversary with an open house on Friday, June 3, from 4 to 7 p.m. in the Elvey and Akasofu buildings at the University of Alaska Fairbanks.

A short welcome ceremony will launch the festivities at 4 p.m. in the lobby of the Akasofu Building on UAF's West Ridge.

The event, suitable for all ages, features a First Friday art show highlighting imagery from satellites, including radar images of Earth; activities and exhibits, including coloring books, do-it-yourself satellite-model construction, unmanned aircraft and rocketry; and scientific posters depicting research using radar.

Data and imagery distributed by the Alaska Satellite Facility have been used to track sea ice; study soil moisture; follow the path of the Deepwater Horizon oil spill in the Gulf of Mexico; analyze earthquake damage and faults in Nepal, Japan, Haiti and elsewhere; map wetlands; look at erupting volcanoes; and much more.

Back in 1991, the iconic big blue antenna dish on the top of the Elvey Building on the UAF campus performed its first downlink of data from a satellite. The satellite, known as ERS-1, was launched by the European Space Agency, and the data was shared with scientists under an agreement with NASA. Ever since then, funded solely by contracts and grants, the Alaska Satellite Facility has supported research in Alaska and around the world. The facility is part of the UAF Geophysical Institute.

Over the past quarter century, the facility has developed three arms: a NASA Distributed Active Archive Center, the ASF Ground Station and the ASF Enterprise. As a NASA DAAC, one of 12 in the nation, the Alaska Satellite Facility archives more than 2.5 petabytes of synthetic aperture radar data and imagery for distribution to scientific users around the world. Scientists use this data to study subjects including ecology, volcanoes, glaciers, earthquakes, sea ice, climate change and more. SAR bounces a signal off the surface of Earth to detect physical properties including surface shape, surface roughness and vegetation cover. Unlike optical sensors, such as those on Landsat satellites, SAR can see through darkness, clouds and rain.

The ASF Ground Station, with three NASA antennas that are Fairbanks landmarks on the university’s West Ridge, supports polar-orbiting, Earth-imaging spacecraft from its prime polar location. In addition to the dish on top of the Elvey Building, the ASF station operates the two 11-meter antennas near the UAF ski trails. The full-service station operates 24 hours a day, seven days a week, providing downlink, uplink and coherent tracking services. It is is the only university-based member of the Near Earth Network, a global array supporting missions by NASA and others. The network, managed by NASA Goddard Space Flight Center, has more than a dozen ground stations that provide telemetry, commanding, ground-based tracking, data and communications services to a wide range of customers.

ASF Enterprise operates a separate, off-campus, full-service ground station, using university-owned antenna systems to support space agencies, small-satellite operators and data providers. In addition, ASF Enterprise provides SAR training to assist the research and hazard response communities in understanding and applying SAR data to their specific applications.
