WALLOPS ISLAND, Virginia — Northrop Grumman is ready to launch a Cygnus cargo spacecraft atop what would be the last flight of the Antares 230+ rocket.
The NG-19 mission to the Worldwide Area Station will start with a liftoff schedule for 8:31 p.m. EDT (00:31 UTC) Aug. 1, 2023, from NASA’s Wallops Flight Facility on Wallops Island in Virginia. Aboard can be hundreds of kilos of cargo, gear and science experiments certain for the outpost’s seven-person Expedition 69 crew.
Due to Russia’s battle in Ukraine, this would be the last launch of the rocket on this configuration.
The primary stage core constructions and propellant programs of Antares 230+ had been manufactured by Yuzhmash State Enterprise beneath the design authority of Yuzhnoye SDO in Dnipro, Ukraine, and the primary stage’s RD-181 engines made by Russian producer Energomash are not being delivered resulting from Russian sanctions on the U.S. and vise versa.

Given this dependency on abroad suppliers, Northrop Grumman had been in search of an area associate. In August 2022, the corporate introduced a partnership with Firefly Aerospace to develop a home model of the rocket. This transfer not solely reduces vulnerability resulting from worldwide political developments but additionally positions the corporate to compete for contracts from the Division of Protection.
The brand new rocket can be referred to as the Antares 330. As a result of the propulsion expertise of Firefly employs the identical propellants as the present Antares rocket, it diminishes the requirement for substantial alterations on the gas farm on the Wallops launch website.
Seven of Firefly’s Miranda engines will energy the Antares 330, and it’ll additionally harness Firefly’s composite expertise for constructing the primary stage constructions and tanks.
Concurrently, Northrop Grumman will contribute its tried-and-tested avionics and software program, upper-stage constructions, and the Castor 30XL motor, coupled with its proficiency in car meeting and launch pad procedures. This new stage is ready to considerably enhance the orbit-bound payload capability of the Antares rocket.
The upgraded Antares 330 rocket could make its first look as quickly as the top of 2024.

In an effort to cowl the transitional service hole of Antares, Northrop Grumman has acquired three SpaceX Falcon 9 launches, guaranteeing the continuity of Cygnus house station cargo deliveries with minimal disruption.
With the NG-19 mission, Northrop Grumman is marking 10 years of offering industrial resupply companies missions. To date, Cygnus has transported roughly 130,000 kilos (59,000 kilograms) of essential cargo, provides, gear and scientific experiments to the crews of the Worldwide Area Station.
The launch of the NG-19 spacecraft, dubbed S.S. Laurel Clark, will happen from the Mid-Atlantic Regional Spaceport’s Pad 0A, situated on Wallops Island, Virginia. The spacecraft is set to transport some 8,200 pounds (3,700 kilograms) of scientific research, provides for the crew and gear to the house station in an effort to help the Expedition 69 crew.
One of many experiments aboard is known as Neuronix, a mission supported by the ISS Nationwide Lab, which is able to discover the creation of three-dimensional neuron cell cultures in a microgravity atmosphere and experiments with a gene remedy particularly designed for neurons.
One other is Saffire VI, which is able to ship a vital normal for verifying fashions of how hearth impacts the livability of a spacecraft.
Moreover, there’s the Multi Needle Langmuir Probe, which is able to monitor the densities of plasma within the ionosphere and the Exploration PWD, which is able to make use of cutting-edge strategies for water sanitization and lowering microbial progress, and it additionally gives scorching water.
The Cygnus system is constructed upon a confirmed and efficient design, incorporating parts from each Northrop Grumman and its associate corporations. It consists of a service module, developed by Northrop Grumman, and a pressurized cargo module, which is constructed by Thales Alenia Area. Collectively, these modules work in tandem to make sure the profitable functioning of the Cygnus system, supporting its mission to ship important provides and gear to the ISS.
Throughout its cargo resupply missions to the ISS, the Cygnus car has showcased a variety of refined talents. These embrace autonomous navigation, deploying dice satellites from exterior deployers, transporting stay rodents to the station, serving as a practical laboratory whereas docked to the station, elevating the station’s orbit and autonomously working in orbit for prolonged intervals, surpassing one yr.
As soon as in house, the NG-19 Cygnus spacecraft is predicted to take about two days to succeed in the ISS the place it is going to spend a number of months connected to the Earth-facing port of the Unity module.
