HOUSTON (NASA PR) — The Orbital ATK Cygnus cargo ship was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 7:15 a.m. EST. The spacecraft will spend about three weeks attached to the space station before departing in early December. After it leaves the station, the uncrewed spacecraft will deploy several CubeSats before its fiery re-entry into Earth’s atmosphere as it disposes of several tons of trash.
The spacecraft’s arrival brings close to 7,400 pounds of research and supplies to support Expedition 53 and 54. Highlights include:

The coli AntiMicrobial Satellite (EcAMSat) mission, which will investigate the effect of microgravity on the antibiotic resistance of E. coli, a bacterial pathogen responsible for urinary tract infection in humans and animals. Antibiotic resistance could pose a danger to astronauts, especially since microgravity has been shown to weaken human immune response. The experiment will expose two strains of E. coli to three different doses of antibiotics; one of these strains is deficient in the gene responsible for the increased antibiotic resistance in microgravity. Results from this investigation ...
