ULA Atlas V Rocket With Cygnus Spacecraft at the Launch Pad
A United Launch Alliance Atlas V rocket with Orbital ATK's Cygnus cargo spacecraft on top stands at the launch pad at Space Launch Complex 41, Cape Canaveral Air Force Station, Florida on Dec. 3, 2015. Launch of Cygnus on the CRS-4 resupply mission to the International Space Station is scheduled for 5:55 p.m. EST on Dec. 3, and the weather forecast is 60 percent favorable. A launch today will result in Cygnus arriving at the space station on Sunday, Dec. 6. NASA crew members Kjell Lindgren and Scott Kelly will use the station’s Canadarm2 robotic arm to reach out and capture Cygnus.
Cygnus will deliver samples and equipment to the station for research investigations in the many science disciplines aboard the orbiting multi-disciplinary laboratory. Research equipment includes the Space Automated Bioproduct Lab (SABL), a single locker-sized facility that will enable a wide variety of fundamental, applied and commercial life sciences research, as well as K-16 education-based investigations. CRS-4 will also carry the Packed Bed Reactor Experiment (PBRE), an investigation studying the behavior of gases and liquids when they flow simultaneously through a column filled with fixed porous media. Another investigation launching aboard CRS-4 is the Burning and Suppression of Solids – Milliken (BASS-M) investigation, which examines the extinction characteristics of a variety of flame retardant textiles in microgravity when exposed to a controlled flame.

With no signs poor weather conditions would clear in time for a launch today, the launch managers scrubbed today’s try. The United Launch Alliance Atlas V rocket and Orbital ATK Cygnus spacecraft will be configured to launch tomorrow at 5:33 p.m. EST, the opening of a 30-minute window. The forecast tomorrow calls for a 30 percent chance of acceptable conditions at launch time. Continuous countdown coverage here and on NASA TV will begin at 4:30 p.m. EST.

Launch Moves to Sunday: Forecast 40 Percent ‘Go’
-
The launch of Orbital ATK’s Cygnus cargo spacecraft to the International Space Station has moved to Sunday at 4:44 p.m. EST, the start of a 30-minute launch window for the uncrewed spacecraft to begin it mission. Countdown and launch coverage will begin here on the NASA Blog and on NASA TV at 3:45 p.m.
Saturday’s attempt was called off because of high winds that were expected to violate launch criteria throughout the 30-minute launch window. The weather forecast for Sunday improved to a 40 percent chance of acceptable conditions at launch time.

United Launch Alliance Successfully Launches OA-4 Cygnus to International Space Station
Cape Canaveral Air Force Station, Fla., (Dec. 6, 2015) – A United Launch Alliance (ULA) Atlas V rocket carrying the OA-4 Cygnus resupply spacecraft to the International Space Station lifted off from Space Launch Complex-41 Dec. 6 at 4:44 p.m. EST.
The mission, flown for Orbital ATK under NASA’s Commercial Resupply Services contract, marks the first time the Cygnus has flown on an Atlas V rocket. This was ULA’s 12th launch in 2015. At just over 8 tons, Cygnus is the heaviest payload to launch atop an Atlas V rocket.
“Congratulations to the team on today’s successful launch! Partnering with Orbital ATK to launch the Cygnus resupply vehicle to the ISS for NASA, a first for ULA, marks a great achievement for the team, and has provided a critical service to the nation and to the crew on the ISS,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs. “This mission is delivering more than 7,000 pounds of cargo including supplies for the crew and critical materials supporting science and research investigations.”
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.
"In the 12 months since this launch was ordered, the ULA and Orbital ATK teams worked very closely together to integrate the Cygnus with the Atlas launch system, including development of a new structural adapter and also a mission design that includes a 30-minute launch window for this ISS rendezvous mission, ” said Sponnick.
This mission was launched aboard an Atlas V 401 configuration vehicle, which includes a 4-meter diameter payload fairing. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.
ULA's next launch is the GPS IIF-12 satellite for the U.S. Air Force, scheduled for Feb. 3, 2016, from Space Launch Complex-41 from Cape Canaveral Air Force Station, Florida.
With more than a century of combined heritage, United Launch Alliance is the nation’s most experienced and reliable launch service provider. ULA has successfully delivered more than 100 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.

Cygnus will be grappled at approximately 6:10 a.m. on Wednesday, Dec. 9, by NASA astronaut Kjell Lindgren, using the space station's Canadarm2 robotic arm to take hold of the spacecraft. Scott Kelly of NASA will support Lindgren in a backup position. The spacecraft will spend more than a month attached to the space station before its destructive re-entry into Earth’s atmosphere, disposing of about 3,000 pounds of trash.
