60TH LAUNCH OF THE ATLAS V
BREVARD COUNTY • CAPE CANAVERAL AIR FORCE STATION – U.S. Air Force 45th Weather Squadron forecasters continue to predict a 60 percent chance of favorable weather for launch of Orbital ATK CRS-4.
Liftoff of the United Launch Alliance Atlas V rocket and Orbital ATK Cygnus spacecraft is targeted for 5:55 p.m. EST on Thursday, Dec. 3, from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.
The United Launch Alliance Atlas V 401 will launch the Orbital ATK’s Cygnus spacecraft on the initial leg of its cargo resupply mission to the International Space Station (ISS).
Date/Site/Launch Time: Thursday, Dec. 3, 2015, from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida. The mission will launch during a 30-minute window that opens at approximately 6 p.m. EST.
Mission Description: Cygnus is a low-risk design incorporating elements drawn from Orbital ATK and its partners’ existing, flight-proven spacecraft technologies. Cygnus consists of a common Service Module (SM) and a Pressurized Cargo Module (PCM).
The SM is assembled and tested at Orbital ATK’s Dulles, Virginia, satellite manufacturing facility and incorporates systems from Orbital ATK’s flight-proven LEOStar™ and GEOStar™ satellite product lines. The PCM is based on the Multi-Purpose Logistics Module (MPLM), developed and built by Thales Alenia Space of Italy.
The Cygnus spacecraft for the OA-4 mission is the first to employ the longer, “enhanced,” PCM which can carry a greater volume of cargo than the PCM flown on previous missions, and lightweight UltraFlex arrays developed and built by Orbital ATK’s Goleta, California, facility.
Launch Notes: OA-4 will mark the 60th launch of the Atlas V and the 30th launch in the 401 configuration. It also marks ULA’s first mission supporting ISS cargo resupply.
