Weekly Recap From the Expedition Lead Scientist, week of Nov. 14, 2016

ISS - Expedition 50 Mission patch.

Nov. 22, 2016

(Highlights: Week of Nov. 14, 2016) - As the crew of the International Space Station prepared for the arrival of Expedition 50 crewmembers NASA astronaut Peggy Whitson, Russian cosmonaut Oleg Novitskiy of Roscosmos, and ESA astronaut Thomas Pesquet, who launched on Nov. 17, research continued on a variety of investigations including looking for meteors by turning away from deep space and watching the skies below the station.

NASA astronaut Shane Kimbrough inserted a fresh hard drive to record new images for the Meteor Composition Determination (Meteor) investigation making space-based observations of the chemical composition of meteors. The investigation captures high-resolution video and photographs of space rocks falling through Earth’s atmosphere using a software program to search for bright spots, which can later be analyzed on the ground. Measurements made by a spectrograph help determine a meteor's chemical makeup.

Meteors are relatively rare, and are difficult to monitor from the ground because of the interference created by Earth’s atmosphere. Investigating the elemental composition of meteors is important to our understanding of how planets developed. Continuous measurement of meteors and their interaction with Earth's atmosphere could help spot previously undetected or unnoticed meteors as they descend toward the ground. The investigation is installed in the station's Window Observational Research Facility (WORF).

Kimbrough installed a new facility on the space station that cuts back on crew involvement with autonomous payloads, giving them more time to spend on more complex investigations. The NanoRacks Black Box or Science Box is a footlocker-sized box designed to host a number of experiments with practically no monitoring from the crew. The box is installed in the Japanese Experiment Module (JEM) and, after connection to the appropriate cables, ground teams took over, commanding their investigations as needed and watching them through a video feed. These scientists confirmed the investigations currently installed in the Science Box were working as expected.

Kimbrough took time to perform a unique outreach activity, sharing the book “I, Humanity” by Jeffrey Bennett as part of the Story Time From Space program -- an outreach effort combining literacy with science demonstrations recorded in orbit. Crew members read science, technology-, engineering- and mathematics- (STEM-) related children's books, and complete simple science concept experiments. Kimbrough discussed the subject of the book while on camera, and demonstrated the principles involved. Video and data collected during the demonstrations are downlinked and posted to a video library with accompanying educational materials.

The Story Time program is intended to inspire a new generation of schoolchildren to become interested in the STEM fields. The curriculum may help educators improve student understanding and interest in these subjects, preparing the next generation to pursue space-related careers.

Expedition 50 Suits Up and Launches

Crew members also conducted human research investigations this week, including Fine Motor Skills, Dose Tracker and Space Headaches.

Progress also was made on other investigations and facilities this week, including Veg-03, ISS Ham, ACE-T-1, EML Batch 1, Radi-N2, and the Fluid Science Laboratory.
