1985-076A
During EVA-1, Van Hoften captured Leasat 3. The satellite was safed by stowing the sep lever, installing two shorting plugs, and installing two safe-and-arm pins. The theta=135 and theta=90 closeout plates and connector flight caps were removed. SBU (Spun Bypass Units) harness connectors were mated and SBU plates and flight caps were installed. The RPU (Remote Power Unit) and RPU harness connections were attached, and the RDU (remote decoder unit) relays were enabled. The omni-antenna squibs were fired and the omni antenna was deployed. The despun caps and closeout plates were reattached.
On EVA-2, the PKM nozzle cover was removed and a new one installed. The safe-and-arm pins were removed, the SBU and timers were powered up, the grapple and handling bar was removed, and the spin-up bar was installed. Van Hoften then spun up the satellite to 2.7 rpm and released it. The spin rate was later increased to 24 rpm by ground command.
