On Sunday, July 13, 2014 at 1652 UTC (1252 EDT) from Launch Pad-0A (LP-0A) at Wallops Flight Facility (WFF), Mid-Atlantic Regional Spaceport (MARS), Virginia; Orbital Sciences will be launching Cygnus Spacecraft atop an Antares rocket as part of Orb-2. This will be Orbital’s third overall flight to the International Space Station (ISS) and the second official resupply mission as part of NASA’s Commercial Resupply Services (CRS) initiative.

After free-drift the spacecraft will be grappled via the Canada-Arm and berthed to the Harmony Module of the ISS where it will remain for approximately six months before being loaded with waste and released to disintegrate in Earth’s atmosphere.

This mission is dedicated to former NASA astronaut and Orbital Sciences employee, Janice Voss. She is represented by the gold trim on the Orb-2 mission patch.


CYGNUS SPACECRAFT = Expendable, unmanned, pressurized cargo re-supply spacecraft built by Thales Alenia of Italy. Its 3.6 meters (11.8ft) in length, 3 meters (9.8ft) in diameter and has a pressurized volume of 18.9 cubic meters. CYGNUS Fact Sheet: https://www.orbital.com/AdvancedSystems/Publications/Cygnus_factsheet.pdf


ANTARES ROCKET = Formerly known as Taurus II, the newly renamed Antares Launch Vehicle is a 2 stage medium-lift rocket (with optional 3rd stage). It stands 40.5 meters (132.8ft) high and is 3.9 meters (12.9ft) in diameter. The (1-2-0) numbering system for Antares goes as follows: 1) Two standard AJ26-62 first stage engines. 2) Castor 30B second stage engine. 0) Third stage not utilized.

MAIN PAYLOAD FAIRING = Two-shell composite 9.9 meters (32.5ft) high and 3.9 meters (12.8ft) in diameter.

OPTIONAL THIRD STAGE = There are two optional third stage variations; the STAR 48BV and the Bi-Propellant Third Stage (BTS). Neither of these will be used during this flight.

SECOND STAGE = 4.2 meters (13.8ft) in height and 2.3 meters (7.5) in diameter. It’s powered by a single ATK Castor 30B (CASTOR 120 Heritage) solid fueled engine with thrust vectoring capability that burns for 127 seconds.

FIRST CORE/BOOST STAGE = is 27.6 meters (90.5ft) in height and 3.9 meters (12.8ft) in diameter and is powered by 2 AeroJet AJ26-62 engines which are actually converted Russian NK-33 engines, YES, the same engines that were going to fly the massive Soviet N1 Moon Rocket off of the Earth’s surface and on to the Moon. They are liquid fueled, burning Liquid Oxygen / Rocket Propellant-1 Kerosene (LOX/RP-1) and burn for 235 seconds. GO ANTARES – GO CASTOR – GO CYGNUS & GO ORB-2!!!
