During the fifth launch on October 28, 2014, the rocket failed catastrophically, and the vehicle and payload were destroyed. The failure was traced to a fault in the first stage engines. 9 billion for 8 flights was awarded in 2008. On June 10, 2008, it was announced that the Mid-Atlantic Regional Spaceport, formerly part of the Wallops Flight Facility, in Virginia, would be the primary launch site for the rocket. On December 10, 2009, Alliant Techsystems Inc. Castor 30 motor for use as the second stage of the Antares rocket. The Antares 100-series first stage was powered by two Aerojet AJ26 engines.
These began as Kuznetsov NK-33 engines built in the Soviet Union in the late 1960s and early 1970s, 43 of which were purchased by Aerojet in the 1990s. Following the catastrophic failure of an AJ26 during testing at Stennis Space Center in May 2014 and the Orb-3 launch failure in October 2014, likely caused by an engine turbopump, the Antares 100-series was retired. Due to concerns over corrosion, aging, and the limited supply of AJ26 engines, Orbital had selected new first stage engines. The new engines were planned to debut in 2017 and allow Orbital to bid on a second major long-term contract for cargo resupply of the ISS. AJ26 engines used on the Antares 100. OA-12, scheduled for late 2019, will be the first NASA CRS-2 mission to ISS. Additionally, the company is working on trajectory improvements via a „load-release autopilot“ that will provide greater mass to orbit capability.
The second stage is an Orbital ATK Castor 30-series solid-fuel rocket, developed as a derivative of the Castor 120 solid motor used as Minotaur-C’s first stage. The initial design of the Castor 30XL was conservatively built, and after gaining flight experience it was determined that the structural component of the motor case could be lightened. Star 48-based third stage and an Orion 38 motor. On January 14, 2016, NASA awarded three cargo contracts via CRS2. Orbital ATK’s Cygnus was one of these contracts. A further improved version is in development which will include: Stage 1 core updates including structural reinforcements and optimization to accommodate increased loads. Cygnus cargo load and optimized fairing adapter structure.
Previously, it was understood that these planned upgrades from the Antares 230 series would create a vehicle known as the Antares 300 series. However, when asked specifically about Antares 300 series development, Mr. The first two test flights used a Castor 30A second stage. All subsequent flights will use either a Castor 30B or Castor 30XL.
Prior to the launch, a 27-second test firing of the rocket’s AJ26 engines was conducted successfully on February 22, 2013, following an attempt on February 13 which was abandoned before ignition. A-ONE used the Antares 110 configuration, with a Castor 30A second stage and no third stage. The first attempt to launch the rocket, on April 17, 2013, was scrubbed after an umbilical detached from the rocket’s second stage, and a second attempt on April 20 was scrubbed due to high altitude winds. At the third attempt on April 21, the rocket lifted off at the beginning of its launch window. Antares A-ONE, Antares test flight, using a Castor 30A second stage and no third stage. First Antares mission with a real Cygnus capsule, first mission to rendezvous and berth with the International Space Station, second launch of Antares. Cygnus, and first Antares launch using the Castor 30B upper stage.
Spacecraft carried supplies for the ISS, including research equipment, crew provisions, hardware, and science experiments. Rocket fell back onto the pad and exploded. First Antares launch to use Castor 30XL upper stage. First launch of Enhanced Cygnus on Orbital’s new Antares 230. Spacecraft carried ISS hardware, crew supplies, and scientific payloads, including the Cold Atom Lab and the Biomolecule Extraction and Sequencing Technology experiment. The Cygnus also demonstrated boosting the station’s orbital velocity for the first time, by 0. Note: Cygnus CRS OA-4, the first Enhanced Cygnus mission, and OA-6 were propelled by Atlas V 401 launch vehicles while the new Antares 230 was in its final stages of development.
