Electric Propulsion for Station Keeping and Electric Orbit Raising on Eutelsat Platforms
Electric Propulsion for Station Keeping and Electric Orbit Raising on Eutelsat Platforms 2015-b/IEPC-97 Presented at Joint Conference of 30th International Symposium on Space Technology and Science 34th International Electric Propulsion Conference and 6th Nano-satellite Symposium, Hyogo-Kobe, Japan July 4 – 10, 2015 C. Casaregola1 Eutelsat, Paris, 75015, France Abstract: With a fleet of 34 geostationary satellites and more than 30 years of service from space, Eutelsat is today Europe’s most long-standing satellite operator and one of the world’s leading satellite operators. The first two platforms using Electric Propulsion procured are SESAT-1 (EUTELSAT 16C) and KA-SAT, for which Electric Propulsion is limited to on-station operations. The successful demonstration of sustained capability of Electric Propulsion for these two platforms in addition to the extensive flight heritage with no significant anomalies demonstrated in the last decades on both commercial and scientific platforms, prove the high level of maturity reached by Electric Propulsion systems. Based on that and due to new attractive launch options, one full-electric platform - EUTELSAT 115 West B – has been procured and launched in March 2015. The launch of EUTELSAT 115 West B is a key milestone for telecom platforms as it makes Eutelsat the first Operator to use Electric Propulsion for a complete electric orbit raising. Two additional platforms – EUTELSAT 117 West B and EUTELSAT 172 B - are under procurement and will perform complete electric orbit raising as well. An overview of Eutelsat platforms using Electric Propulsion for station keeping and electric orbit raising is given in the paper. -

Gazda5 NASA Johnson Space Center, Houston, Texas, 77058 This paper continues the annual tradition, at this conference, of summarizing the results of chemical analyses performed on archival potable water samples returned from the International Space Station (ISS). 2016 represented a banner year for life aboard the ISS, including the successful conclusion for 2 crewmembers of a record 1-year mission. Water reclaimed from urine and/or humidity condensate remained the primary source of potable water for the crewmembers of ISS Expeditions 46-50. The year was also marked by the end of a long-standing tradition of U.S. sampling and monitoring of Russian Segment potable water sources. Two water samples, taken during Expedition 46 and returned on Soyuz 44 in March 2016, represented the final Russian Segment samples to be collected and analyzed by the U.S. side. Although anticipated for 2016, a rise in the total organic carbon (TOC) concentration of the product water from the U.S. water processor assembly due to breakthrough of organic contaminants from the system did not materialize, as evidenced -

Battling Homesickness on Mars the Relationship Between Relatedness, Well-Being, Performance, and Displacement in a Mars Simulation Study
BATTLING HOMESICKNESS ON MARS THE RELATIONSHIP BETWEEN RELATEDNESS, WELL-BEING, PERFORMANCE, AND DISPLACEMENT IN A MARS SIMULATION STUDY Word count: 19,040 Thomas J. N. Van Caelenberg Student number: 00907011 Supervisors: Prof. Wim Beyers, Dr. Sophie Goemaere A dissertation submitted to Ghent University in partial fulfilment of the requirements for the degree of Master of Clinical Psychology Academic year: 2016 - 2017 Abstract During a Mars mission, crew will simultaneously be confined to small shared living quarters, and will experience extreme geographical and temporal isolation from all other people. Under these circumstances, group tensions have been known to cause communication issues with mission support; a phenomenon called displacement. To gain further insight in these challenges, this study investigated the effects of the psychological need for relatedness as described by the Self-Determination theory, a macro theory on human motivation. During a yearlong Mars simulation, HI-SEAS IV, six crewmembers filled out weekly self-report questionnaires measuring their level of relatedness with friends and family at home as well as fellow crewmembers living inside the Mars simulation. Crew further filled out questionnaires measuring their well-being, performance, and displacement with mission support staff outside the station. Using hierarchical modelling, the results indicated that relatedness was a predictor of crewmembers’ well-being, performance and displacement. Relatedness with fellow crewmembers was a positive predictor of crewmembers’ well-being and performance, and was a negative predictor of displacement. Relatedness with friends and family at home was a positive predictor of well- being and a negative predictor of displacement. Overall, the results provide evidence for the presence of the psychological need for relatedness as affecting crewmembers’ well-being, work performance, and displacement toward mission support, successfully applying the Self-Determination theory to a spaceflight setting. -
