HDEV

Component data:

Description:

• The HDEV payload was designed, built, and ready for shipment to Kennedy Space Center for launch by March 2012. The payload′s rapid design to flight hardware build was attributed to utilizing of COTS hardware. COTS hardware could be used because there were fewer requirements on this payload not being mission critical to the ISS and crew.
• Despite the quick design and payload manufacturing, the payload was not placed on a manifest until the launch of SpaceX Cargo Resupply (CRS) 3, two years later. HDEV was launched on SpaceX CRS-3 on April 2014. The wait time was due to numerous changes in launch schedule. Once delivered to the ISS, HDEV was quickly installed and activated just 12 days later on April 30, 2014.
• Until HDEV, the International Space Station (ISS) flew with standard definition external cameras, and internal HD cameras, which downlinked a combination of six independent video streams during end-to-end signal connections. Now with HDEV installed, the ISS had four HD cameras continuously operating on the exterior with no required crew intereaction.
• The HDEV installation was notable because robotic transfer from launch vehicle′s trunk to external payload operational site installed the payload. Therefore, no scheduled Extravehicular activity (EVA) or Extra Vehicular Robotics (EVR) maintenance requirements was required for this external payload, and no ISS crew interaction was required. The Special Purpose Dexterous Manipulator, the Canadian Space Agency′s robotic handyman, also known as Dexter, and the Canadarm2 or Space Station Remote Manipulator System arm removed the payload, from the trunk to mount it on the nadir adapter of the European Space Agency&prime:s Columbus exposed facility. Using an automated robotic arm as automated process was carried out for the first time in the ISS program with the installation of the HDEV payload.

Mission details:

• HDEV was launched on SpaceX CRS-3 on 18 April 2014.
• On May 7, 2020 the Dextre arm removed the HDEV Earth viewing experiment from its attachment point on the Columbus module and installed it on the exterior of the Cygnus NG-13 cargo ship for disposal.
