Atlas V

American orbital launch vehicle. The Atlas V launch vehicle system was a completely new design that succeeded the earlier Atlas series. Atlas V vehicles were based on the 3.8-m (12.5-ft) diameter Common Core Booster (CCB) powered by a single Russian RD-180 engine. These could be clustered together, and complemented by a Centaur upper stage, and up to five solid rocket boosters, to achieve a wide range of performance.

Status: Active. Payload: 12,500 kg (27,500 lb). Thrust: 8,590.00 kN (1,931,100 lbf). Gross mass: 546,700 kg (1,205,200 lb). Height: 58.30 m (191.20 ft). Diameter: 3.81 m (12.49 ft). Span: 5.40 m (17.70 ft). Apogee: 185 km (114 mi).

When combined with a standard Atlas payload fairing, the configuration was designated as the Atlas V 400 series. The Atlas V 500 series combined the CCB with a larger 5 m diameter payload fairing derived from that used on the Ariane 5 vehicle The Atlas V 500 series could also tailor performance by incorporating from zero to five solid rocket boosters (SRB).

Both Atlas V 400 and 500 configurations incorporated a stretched version of the Centaur upper stage (CIII), which could be configured as a single-engine Centaur (SEC) or a dual engine Centaur (DEC). The Atlas V family of launch vehicles could be launched from either Cape Canaveral Air Station Launch Complex 41 or Vandenberg Air Force Base Space Launch Complex 3W.

A three-digit naming convention was developed for the Atlas V launch vehicle system to identify it's multiple configuration possibilities, as follows: the first digit identified the diameter class (in meters) of the payload fairing (4 or 5 m); the second digit indicated the number of solid rocket motors used (zero for Atlas V 400 and zero to five for Atlas V 500); the third digit represented the number of Centaur engines (one or two). Payload performance of the possible variants were as follows (payloads over 9,050 kg would require structural modification to the basic vehicle):

The Atlas deployed two NRO satellites and a cluster of cubesats in orbit. Items listed as USA 264 and USA 264 'debris', thought to be a clandestine active payload, were deployed in a 1014 km x 1201 km x 63.4 deg orbit.

United Launch Alliance launched Atlas V flight AV-061 carrying the Cygnus OA-4 cargo ship mission. Following the Antares failure in the prior year, Cygnus payloads were temporarily moved to Atlas. The OA-4 Cygnus, called 'SS Deke Slayton II', was the first Cygnus with the enhanced (stretched) EPCM pressurized cargo module, and the first with a service module carrying the circular UltraFlex solar arrays originally designed for NASA's Orion. This was the first time an Atlas launched a payload towards the ISS. The AV-061 Centaur reached a 234 x 237 km orbit at 2203 UTC, released Cygnus 3 min later, and performed a 10s deorbit burn at 2232 UTC for disposal of the Centaur in the ocean south of Australia at about 132E 49S. The Deke Slayton II reached the ISS on Dec 9, with SSRMS grapple at 1119 UTC and berthing on Harmony at 1426 UTC. Aboard the Cygnus were the small NovaWurks SIMPL satellite, 12 Flock 2e cubesats from Planet Labs, and the CADRE, STMSat-1, MinXSS-1, Nodes 1 and Nodes 2 cubesats. Mass of ISS after the OA-4 arrival was 418 metric tons. The Canadarm-2 unberthed the Cygnus OA-4 cargo ship, SS Deke Slayton II, from the Unity node on Feb 19 at 1040 UTC and released it into orbit at about 1227 UTC. The Cygnus was deorbited over the S Pacific at about 1600 UTC Feb 20.

Cygnus cargo ship OA-6, "SS Rick Husband", was launched aboard Atlas V flight AV-064. A mixture ratio problem on the Atlas caused an 5-seconds-early first stage cutoff, which required a full extra minute's burn on the Centaur upper stage to make the correct orbit. After deploying Cygnus, the Centaur's second burn was intended to deorbit the stage south of Australia, but because of insufficient remaining propellant the engine cutoff early, and reentry occurred downrange south of New Zealand. SS Rick Husband arrived at the ISS on schedule, and was grappled by the Canadarm-2 at 1051 UTC Mar 26. On Jun 14 the Canadarm-2 unberthed Cygnus OA-6 from the Unity module at 1143 UTC and released it into orbit at 1330 UTC. Cygnus then performed the SAFIRE-1 experiment igniting a significant fire inside an experiment chamber in the Cygnus pressurized PCM module. Mounted on the Cygnus service module was the first NRCSD-E external cubesat deployer carrying 5 Lemur-2 satellites. On Jun 21 two pairs of Lemur-2 cubesats were ejected. A third deployer silo with a single Lemur-2 failed to open, and the cubesat remained inside when then following day Cygnus made its deorbit burn and reentered over the South Pacific at 1329 UTC Jun 22.

The Atlas 5 rocket made three burns to 167 x 659 km x 28 deg, 191 x 32930 x 26 deg and then 3802 x 35786 km x 19 deg, and deployed MUOS which will use its Japanese BT-4 thruster to reach GEO over the Indian Ocean as an in-orbit spare for the system, whose 4 operational satellites were over the Atlantic, the Pacific, the Indian Ocean and the Americas. MUOS 5 had problems with its propulsion system and was parked in a 15242 x 35703 km x 9.8 deg intermediate geotransfer orbit.

OSIRIS-REx had a mass of 834 kg, and carried 1230 kg of propellant and a 46 kg sample return capsule identical to the one used by the Stardust mission. OSIRIS-REx was to make an Earth flyby in Sep 2017 to change its orbit to 0.90 x 1.35 AU x 6.4 deg, allowing it to rendezvous with asteroid (101955) Bennu in Aug 2018.
