SpaceX COTS UHF Communication Unit and Crew Command Panel
In a middeck stowage locker, Atlantis carried the Commercial Orbital Transportation Services (COTS) Ultra High Frequency (UHF) Communication Unit (CUCU) developed by Space Exploration Technologies (SpaceX) in collaboration with NASA to the ISS. It will be integrated on the space station in preparation for future SpaceX flights to the orbiting complex. The unit allows for communication between ISS and SpaceX's Dragon spacecraft via a UHF radio. Commands from SpaceX can be forwarded through ISS to CUCU and on to Dragon. Similarly, telemetry from Dragon and CUCU can be forwarded down through ISS for monitoring by SpaceX and NASA ground-based mission control. The Crew Command Panel (CCP) provides feedback about the state of the Dragon vehicle to astronauts aboard ISS. It additionally provides some simple commanding capability to the astronauts to be used during the Dragon approach to ISS.

Famous quotes containing the words unit and/or command:
“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
“Universal empire is the prerogative of a writer. His concerns are with all mankind, and though he cannot command their obedience, he can assign them their duty. The Republic of Letters is more ancient than monarchy, and of far higher character in the world than the vassal court of Britain.”
—Thomas Paine (1737–1809)
