Watch Northrop Grumman’s Cygnus spacecraft lift off atop an Antares rocket from NASA’s Wallops Flight Facility in Virginia to deliver cargo to the International Space Station. The Cygnus bears the name S.S. Piers Sellers, in honor of the late NASA astronaut and climate researcher, and will transport research, crew supplies, and hardware to the orbiting laboratory. Onboard science includes:

• A study that examines the effects of a drug on breast and prostate cancer cells
• A new combustion facility
• An investigation on skin aging in microgravity
• New hydrogen sensors that will be tested for the space station’s oxygen generation system
• A system that will test hydroponic and aeroponic techniques for plant growth

NG-17 is Northrup Grumman’s 17th cargo resupply mission to the ISS as a part of the Commercial Resupply Services (CRS). These missions have been essential for transporting crew supplies, like food and clothing, as well as new scientific research experiments to the station since 2014.

Colgate Skin Aging Experiment
A set of engineered human skin cells, the ISS U.S. National Lab’s Colgate Skin Aging experiment aims to study how human skin ages. A natural aspect of the skin, aging occurs more rapidly in a microgravity environment allowing scientists to more easily study how human skin ages.

MicroQuin 3D Tumor
The MicroQuin 3D Tumor experiment will test and measure how a drug works on breast and prostate cells in a microgravity environment. While in microgravity, the drug will be able to affect the cells in a more natural and three-dimensional manner than while under the influence of gravity.

OGA H2 Sensor Demo
In order for astronauts to survive in an environment such as the ISS, they must have the ability to generate, or regenerate, oxygen. The Oxygen Generation System (OGS) on the ISS uses electrolysis, the separation of hydrogen and oxygen in water, to produce breathable oxygen for the astronauts.

Space As-Lib
The Japan Aerospace Exploration Agency (JAXA) has developed new battery technology which will be tested on the ISS sometime this year. It will demonstrate the operation of a lithium ion battery capable of operating in a vacuum and at extreme temperatures. This solid state battery would, if successful, be able to be used in a variety of applications on future space exploration missions.

The Antares 230+ is a two stage expendable rocket designed by Northrop Grumman to launch the Cygnus spacecraft to the ISS. Capable of carrying up to 8,000 kg (~17,600 lb) into Low Earth Orbit (LEO), it is the largest rocket operated by the company.

The first stage uses two Russian RD-181 engines, providing 3,844 kN (~864,000 lbf) of the thrust. The stage runs on Rocket Propellant 1 (RP-1) and liquid oxygen (LOX). It has a specific impulse (ISP) of 311.9 s at sea level and 339.2 s in vacuum. The stage burns for 215 seconds before being jettisoned and crashing into the ocean.

The second stage uses a Castor-30XL solid rocket motor, fueled by hydroxyl-terminated polybutadiene (HTPB) and aluminum. The stage provides 474 kN (~107,000 lbf) of thrust, and runs for 156 seconds.
