Cygnus NG-19

Cygnus NG-19 was the eighth Cygnus mission under the Commercial Resupply Services-2 contract. Northrop Grumman Innovation Systems confirmed on 23 February 2021 that Thales Alenia Space of Turin, Italy, will fabricate two additional Pressurized Cargo Modules (PCMs) for a pair of forthcoming Commercial Resupply Services-2 missions. Current plans are for the two additional Cygnus spacecraft to be designated NG-18 and NG-19. Production and integration of Cygnus spacecraft are performed in Dulles, Virginia. The Cygnus service module is mated with the pressurized cargo module at the launch site, and mission operations are conducted from control centers in Dulles, Virginia and Houston, Texas. == Spacecraft ==

This was the fourteenth flight of the Enhanced-sized Cygnus PCM. == Manifest ==

The Cygnus spacecraft was loaded with a total of of cargo and supplies before its launch, including of pressurized and of unpressurized cargo. The cargo manifest is broken down as follows: • Crew supplies: • Science investigations: • Spacewalk equipment: • Vehicle hardware: • Computer resources: == Research ==

The new experiments arriving at the orbiting laboratory will inspire future scientists and explorers, and provide valuable insight for researchers. NASA Scientific Research studies: • Innovative Paralysis Therapy Enabling Neuroregeneration (Neuronix) - Sponsored by the ISS National Lab, demonstrates the formation of 3D neuron cell cultures in microgravity and tests a neuron-specific gene therapy. Gene therapy shows promise as a potential treatment for people with paralysis and neurological diseases such as Alzheimer’s and Parkinson’s, but the 3D models needed to test these therapies cannot be grown in Earth’s gravity. Creating 3D cell cultures in microgravity could provide a platform for drug discovery and gene therapy testing. • Spacecraft Fire Experiments (Saffire-VI) - Understanding how fire behaves in space is vital for developing fire prevention and fire suppression methods, but flame-related experiments are difficult to conduct aboard an occupied spacecraft. The Spacecraft Fire Experiments (Saffire) use the Cygnus resupply craft after it leaves the space station to remove the risk to crew and spacecraft. Saffire-VI is the last of this series, building on previous results to test flammability at different oxygen levels and to demonstrate fire detection and monitoring as well as post-fire cleanup capabilities. • MVP-Cell-02A - Sponsored by the NASA Biological and Physical Sciences Division (BPS), MVP-Cell-02A is a study aimed at understanding how organisms evolve to adapt to the space environment. During the experiment, Bacillus subtilis bacteria will be grown in specially designed environmental hardware in a range of conditions, allowing researchers to investigate whether the adaptation process occurs differently in microgravity and in the spaceflight environment as a whole. MVP-Cell-02A is a repeat of MVP-Cell-02. == See also ==
