NOTE TO EDITORS:  STS-31 BRIEFING DATE CHANGE
     Due to a change of date in the terminal countdown 
demonstration test (TCDT), the STS-31 briefings and crew press 
conference, originally scheduled for March 19 at the Johnson 
Space Center, Houston, have been postponed until Thursday, March 
22.
     T-0 for the TCDT, orginally set for Thursday, was moved to 
Tuesday because of a revision in launch pad activities at the 
Kennedy Space Center.  TCDT is the crew's traditional dress 
rehearsal for launch day.
     The briefings will begin at 9:30 a.m. EST, Thursday, with 
Flight Director Bill Reeves.  A briefing regarding the secondary 
payloads and the student experiment is set for 10:30 a.m., 
followed by the crew press conference and round robin interviews 
beginning at 11:30 a.m.
     All briefings will be carried on NASA Select television with 
two-way Q and A capability.
