The United States and Soviet Union have agreed to establish a satellite hookup to exchange medical data to help people injured in December's earthquake in Armenia, NASA announced Thursday.

Under the plan, U.S. medical facilities, including one in Utah, would be linked by satellite with Soviet hospitals and rehabilitation centers by Comsat Corp. and Intelsat, which will provide the satellite time free of charge, officials said.The National Aeronautics and Space Administration will provide a compatible satellite ground terminal to be installed in Armenia. The link, to begin operation this spring, would provide one-way television and two-voice capabilities for several hours a day, two days a week.

At least 25,000 people were killed and thousands more were seriously injured in the Dec. 7 quake in Armenia. The temblor leveled several cities and towns, and the resulting injuries strained Soviet medical resources.

The satellite bridge will provide medical consultation to support rehabilitation, reconstructive surgery, physical therapy and psychological counseling, NASA said.

U.S. centers to be hooked up to the network will include the University of Utah; Uniformed Services Health Sciences University, Bethesda, Md.; University of Texas Health Science Center, Houston; and Maryland Institute for Emergency Medical Services, Baltimore.
