Cygnus Cargo Craft Attached to Station for Three-Month Stay

After its capture this morning at 4:05 a.m. EST, the Northrop Grumman Cygnus spacecraft was bolted into place on the International Space Station’s

Earth-facing port of the Unity module at 6:16 a.m. At the time of installation, the space station was flying over south of New Zealand.

The spacecraft’s arrival brings more than 7,500 pounds of research and supplies to space station. Here are some of the scientific investigations:

Better Tissue and Cell Culturing in Space

Mobile SpaceLab, a tissue and cell culturing facility, offers investigators a quick-turnaround platform to perform sophisticated microgravity biology experiments. Such experiments are critical for determining how microgravity affects human physiology and identifying ways to mitigate negative effects. The platform can work in multiple configurations, allowing investigators to tailor the facility to their needs.

Mochii

The Mochii investigation provides an initial demonstration of a new miniature scanning electron microscope (SEM) with spectroscopy. Mochii will demonstrate real-time, on-site imaging and measurements of micro- and nanostructures aboard the space station. This capability could accelerate answers to many scientific inquiries and mission decisions and serve the public as a powerful and unique microgravity research platform.

Examining Bone Loss in Microgravity

Crew members experience bone loss in orbit, stemming from the lack of gravity acting on their bones. OsteoOmics investigates the molecular mechanisms that dictate this bone loss by examining osteoblasts, cells in the body that form bone, and osteoclasts, which dissolve bone. A better understanding of these mechanisms could lead to more effective prevention of astronaut bone loss during space missions.

Fighting Bacteria with Phages

Phage Evolution examines the effects of microgravity and radiation exposure on phage and bacterial host interactions, including phage specificity for a bacterial host and host resistance to specific phages. A better understanding of the effects of microgravity and cosmic radiation on bacteriophages and hosts could result in significant developments for phage technology, ultimately helping protect the health of astronauts on future missions.

(Do Not) Light My Fire

The Spacecraft Fire Experiment-IV (Saffire-IV) investigation examines fire development and growth in different materials and environmental conditions, fire detection and monitoring, and post-fire cleanup capabilities. It is part of a series of fire investigations conducted in the Cygnus resupply vehicle after its departure from space station, eliminating exposure of humans or occupied spacecraft to fire danger.

The Cygnus NG CRS-13 spacecraft for this space station resupply mission is named in honor of U.S. Air Force Maj. Robert Lawrence, the first African American astronaut selected by any program, specifically chosen for the Air Force’s Manned Orbital Laboratory Program in June 1967. Lawrence died in an F-104 Starfighter aircraft accident at Edwards Air Force Base, California six months later at the age of 32.

This is the second time two Cygnus spacecraft will be in flight at the same time, as the NG-12 vehicle remains in orbit after departing from the station on Jan. 31.
