The Northrop Grumman Cygnus cargo ship was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 7:31 a.m. EST. The spacecraft will spend about three months attached to the space station before departing in February 2019. 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 space station. Highlights of NASA-sponsored research to advance exploration goals and enable future missions to the Moon and Mars include:
Sensory input in microgravity
Changes in sensory input in microgravity may be misinterpreted and cause a person to make errors in estimation of velocity, distance or orientation. VECTION examines this effect as well as whether people adapt to altered sensory input on long-duration missions and how that adaptation changes upon return to Earth. Using a virtual reality display, astronauts estimate the distance to an object, length of an ...
