NASA Launches Northrop’s 15th ISS Resupply Mission With Scientific Experiments
Northrop Grumman

A Northrop Grumman-made Cygnus spacecraft with 8,000 pounds of supplies and scientific investigations for NASA was launched for a resupply mission to the International Space Station.

Cygnus, now on its way to ISS, carries projects on microgravity, astronaut sleep quality and technology for water supply, NASA said Sunday.

The spacecraft lifted off on the Antares 230+ rocket from the space agency's Virginia-based Wallops Flight Facility, representing Northrop's 15th cargo mission for ISS.

The mission is also the company's fourth flight under the second round of NASA's Commercial Resupply Services program. 

The first science project, titled “Using worms to learn about muscle loss,” will explore how small worms can help researchers study how microgravity causes muscle pains in astronauts while the second one, named “I dream of space,” will gather data on how a space environment affects human sleep.

The last project, “A life support upgrade,” will seek to update ISS' Environmental Control and Life Support System, which supplies clean water and air. This project will test an experimental technology designed to recover more water from the station's urine processor.

Soichi Noguchi, an astronaut from Japan, will facilitate Cygnus' docking via the Canadarm2 robotic arm system.

ISS will host Cygnus until May and then the spacecraft will begin its re-entry into Earth’s atmosphere.

Accenture’s George Franz, Ian Fogarty: Agile Product Management Could Help DOD Maintain US Innovation Edge

George Franz and Ian Fogarty of Accenture Federal Services wrote in a guest piece published Friday on Breaking Defense that the Department of Defense should combine Agile software development with product management to speed up the development of weapons systems and help maintain U.S. edge in innovation and the country’s global preeminence. “Done correctly, Agile Product Management achieves the speed and responsiveness to evolving needs provided by agile software development, while also helping to handle the complexities associated with suppliers/providers, large and complex integrations, and a wide ecosystem of stakeholders typically seen in mission critical defense and intelligence systems,” Franz, a retired U.S. Army major general, and Fogarty wrote.
