S84-35325 (2 June 1984) --- The Flight Readiness Firing (FRF) for NASA's 41-D spaceflight was completed on June 2, 1984 to pave the way for launch of the Discovery's seven-day mission later this month. Making its first flight, the orbiter will be mated to the same two solid rocket boosters (SRB) and external tank (ET) seen here.
