Northrop Grumman’s Cygnus resupply spacecraft is on its way to the station with approximately 7,500 pounds of science investigations and cargo after launching at 3:21 p.m. EST Saturday, Feb. 15 from NASA’s Wallops Flight Facility in Virginia. At the time of liftoff, the International Space Station was flying 258 statute miles over the western Pacific, northeast of the Northern Mariana Island.

The spacecraft launched on an Antares rocket from the Virginia Mid-Atlantic Regional Spaceport’s Pad 0A at Wallops. Automated command to initiate solar array deploy will begin at 4:40 p.m., about one hour and 19 minutes after launch. Solar array deployment will take about 30 minutes. Confirmation of solar deployment will be shared on the launch blog and social media at @NASA_Wallops and @space_station.

Cygnus is scheduled to arrive at the orbiting laboratory around 4:05 a.m. Tuesday, Feb. 18. Coverage of the spacecraft’s approach and arrival will begin at 2:30 a.m. on NASA Television and the agency’s website. NASA astronaut Andrew Morgan will use the space station’s robotic arm to capture Cygnus, while NASA’s Jessica Meir monitors telemetry. The spacecraft is scheduled to stay at the space station until May.

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.


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.

Northrop Grumman named the NG CRS-13 Cygnus spacecraft after former astronaut Robert Henry Lawrence Jr. Major Lawrence was selected in honor of his prominent place in history as the first African American astronaut.

This is Northrop Grumman’s 13th cargo flight to the space station and will support dozens of new and existing investigations.

SpaceX’s Dragon cargo spacecraft splashed down in the Pacific Ocean at 2:50 p.m. (11:50 a.m. PDT), approximately 300 miles southwest of Long Beach, California, marking the end of the company’s 20th contracted cargo resupply mission to the International Space Station for NASA. The spacecraft returned more than 4,000 pounds of valuable scientific experiments and other cargo.

Some of the scientific investigations Dragon will return to Earth include:

Generating a nutritional meal

Planning ways to supply food for a multi-year mission on the Moon or Mars may require making food and nutrients in space. BioNutrients demonstrates a technology that enables on-demand production of nutrients needed during long-duration space missions. Although designed for space, this system also could help provide nutrition for people in remote areas of our planet.

Toward printing human organs in space

Biological printing of the tiny, complex structures found inside human organs, such as capillaries, is difficult in Earth’s gravity. The BioFabrication Facility (BFF) attempts to take the first steps toward the printing of human organs and tissues in microgravity. The facility may also help maintain the health of crews on deep space exploration missions by producing food and personalized pharmaceuticals on demand.

Helping the heart

The Engineered Heart Tissues (EHTs) study looks at how human heart tissue functions in space. It uses unique 3D tissues made from heart cells derived from human induced Pluripotent Stem Cells (hiPSCs), essentially adult stem cells. Researchers expect significant differences in function, structure and gene expression between EHTs in microgravity and those on the ground. Understanding these differences could help them find ways to prevent or mitigate problematic changes on future long-duration missions.

Biofilm festival

Samples from the Space Biofilms investigation, which examines microbial species and their formation of biofilms, are returning on Dragon. Biofilms are collections of one or more types of microorganisms – including bacteria, fungi and protists – that grow on wet surfaces. Better control of biofilms may help maintain crewed spacecraft and protect the health and safety of crew members as well as help prevent the introduction of Earth-based microbes to planetary bodies on which humans land.

These are just a few of the hundreds of investigations providing opportunities for U.S. government agencies, private industry and academic and research institutions to conduct microgravity research that leads to new technologies, medical treatments and products that improve life on Earth. Conducting science aboard the orbiting laboratory will help us learn how to keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars.

For almost 20 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. As a global endeavor, 239 people from 19 countries have visited the unique microgravity laboratory that has hosted more than 2,800 research investigations from researchers in 108 countries.

The International Space Station expanded its research capabilities overnight after robotics controllers installed a new external science platform. Meanwhile, the Expedition 62 crew is packing cargo for return to Earth while getting ready for its own departure.

Europe’s latest contribution to the orbiting lab, Bartolomeo, was attached to the outside of the Columbus laboratory module early Thursday morning. Robotic engineers remotely commanded the Canadarm2 robotic arm and the Dextre robotic hand and completed the fine-tuned installation work over two days. Bartolomeo, delivered last month aboard the SpaceX Dragon cargo craft, gives private and institutional researchers the ability to command and control science payloads outside the space station.

Commander Oleg Skripochka with NASA Flight Engineers Jessica Meir and Andrew Morgan are preparing to end their mission in space on April 17. They checked their Sokol launch and entry suits they will wear when they parachute to Earth inside the Soyuz MS-15 crew ship for leaks today. The crew is also gathering personal items for stowage inside the Soyuz spaceship.

Before they leave, the SpaceX Dragon space freighter will return to Earth after being released from the Canadarm2 on Monday at 9:52 a.m. EDT. Meir and Morgan will finish loading over 4,000 pounds of station hardware and research samples, including live mice and plant cells, late Sunday. NASA TV will begin its live coverage of Dragon’s departure on Monday at 9:30 a.m.

The station boosted its orbit again today raising it to the correct altitude enabling the new Expedition 63 crew to launch and dock on April 9 inside the Soyuz MS-16 crew ship. NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner will take a six-hour ride to their new home in space and begin a 195-day mission aboard the orbital lab.
