Final Pair of Massive Lockheed Martin Solar Arrays Begin Providing Power to International Space Station
“It is a testament to the professionalism of the STS-119 crew and the mission support team that they made this challenging ISS construction project look easy, and the deployment of the new arrays was a sight to behold,” said
The Space Systems ISS solar arrays are the largest deployable space structure ever built and are by far, the most powerful electricity-producing arrays ever put into orbit. When the Station is completed the eight flexible, deployable solar array wings will generate the reliable, continuous power required for the on-orbit operation of the ISS systems. The eight array wings were designed and built under a
Each of the eight wings consists of a mast assembly and two solar array blankets. The blankets each have 84 panels, of which 82 are populated with solar cells. Each panel contains 200 solar cells. The eight photovoltaic arrays thus accommodate a total of 262,400 solar cells. Fully deployed in space, the active area of the eight wings — each 107 by 38-feet — encompass an area of 32,528-square feet and are designed to provide power to the ISS for 15 years.
In addition to the arrays, Space Systems in
Space Systems also produced the Trace Contaminant Control System — launched to ISS as an element of the U.S. Destiny Laboratory module in 2001 — an advanced air processing and filtering system that ensures that over 200 various trace chemical contaminants, generated from material off-gassing and metabolic functions in the Space Station atmosphere, remain within allowable concentration levels. It is an integral part of the Space Station’s Cabin Air Revitalization Subsystem.
