How many times have you heard someone joke that the job of routing and installing cabling is "not rocket science"? Well, recently it was part of rocket science when a NASA commander routed and installed several new cables aboard the International Space Station.
In two recent updates of NASA's involvement in the ISS mission, the agency reported on the cabling-installation work that Commander Dan Burbank is carrying out aboard the mission.
On March 16, NASA reported that Commander Burbank "had most of his workday (~7 hours) dedicated to one part of major ISS outfitting: upgrading the ISS Ku-band system by routing and installing cabling for the HRCS (High Rate Communication System)." NASA further said the day's work "focused on the routing of four cables in the U.S. Lab Forward Endcone ... Four cables had to be installed today: one Ethernet cable from the Ku-CU (Ku-band Command Unit) to the JSL [Joint Station LAN], one AV-3 power jumper for the Ku-CU2, and two MDM (multiplexer/demultiplexer) 1553 data cable bundles ... Three more installation and cabling tasks will be scheduled at future dates."
On March 20, NASA's report stated, "After last week's routing and installing of cabling for the HRCS ... CDR Burbank had ~2 hours set aside to install a HRCAS AV-2 connector panel ... The panel carries 16 connector plugs, to which Dan mated 9 JSL Ethernet cables of the Ku-CU and 6 Payload Ethernet Hub Gateway 1/Automated Payload Switch data cables."
NASA explained the purpose for this cabling upgrade: "When fully installed and operational, HRCS will provide substantially faster uplink and downlink speeds, improved bandwidth, two extra space/ground voice loops, two extra video downlink channels, and contingency Ku Commanding capability. It will also allow additional data to be downlinked from the payload and command-and-control MDMs through Ku-band using the MDM Ethernet cables routed by the crew during the Enhanced Processor and Integrated Communications (EPIC) work completed earlier ..."

We are pursuing further information from NASA and hope to provide more detail on the cabling work being done on the International Space Station.
