Crew Studies DNA and Space Flames Before Cargo Ship Launch













ISS - Expedition 62 Mission patch.

February 10, 2020

The three-member Expedition 62 crew is getting ready for a resupply mission scheduled to launch to the International Space Station no earlier than Thursday, Feb. 13, at 4:06 p.m. EST due to an unfavorable weather forecast in the next few days and the time required to address a ground support issue. The crewmates from the United States and Russia also ran advanced space science experiments while maintaining orbital lab systems.

NASA Flight Engineers Andrew Morgan and Jessica Meir split their time today between robotics training and microgravity research. The two U.S. astronauts used a computer to practice the techniques they will use to capture the Cygnus space freighter Saturday, Feb. 15.

Morgan will command the Canadarm2 robotic arm to reach out and grapple Cygnus. Meir will back him up and monitor the Cygnus’ approach and rendezvous. Ground controllers will take over the Canadarm2 after Cygnus’ capture and remotely install the cargo craft to the Unity module.

Morgan started his day sequencing DNA for the Genes in Space-6 experiment. The experiment places microbial samples inside the hand-held Biomolecule Sequencer to demonstrate the feasibility of space-based DNA sequencing. Results could boost astrobiology research on not just the space station, but also future spacecraft and planetary bodies.

Meir also spent a portion of Monday researching how flames spread in space. She burned a variety of fabric and acrylic samples inside the Microgravity Science Glovebox for the Confined Combustion study. The research will inform the design and development of fire safety products and procedures for humans on Earth and in space.

Commander Oleg Skripochka spent his day in the Russian segment of the station. The veteran cosmonaut primarily serviced life-support gear before checking components on the Progress 74 cargo craft and updating an inventory database.
