time they are selected as astronauts. IT challenges include: protection of private medical information, access from locations
both inside and outside NASA, nearly 24x7 access, access during disasters, international partner access, data archiving,
off-region backup, secure communication of medical data to people outside the NASA system (e.g. expert consultants),
efficient movement of medical record information between locations, search and retrieval of relevant information, and
providing all of these services/capabilities within a limited budget. In Space Medicine, we have provided for these in various
ways: limit the amount of private medical information stored locally, utilize encryption mechanisms that the international
partners can also use, utilize 2-factor authentication, virtualize servers, employ concept-based search, and use of standardized
terminologies (SNOMED) and messaging (HL7).

The primary objective of this study was to collect human performance data and produce a crew consensus regarding the
feasibility of performing a suited 10-km walkback. All subjects completed the 10-km walkback in less than 2 hours and
completed the test with little difficulty working at about 50% VOZpk. A secondary objective of the study was to understand
the specific human performance limitations of the suit compared to matched unsuited controls. Preliminary analysis indicated
that the metabolic cost of the suit was significant compared to unsuited controls. Weight-matched unsuited trials provided an
initial estimate accounting for the metabolic cost of the suit due to weight, but additional factors such as inertial mass, CG
alterations, pressure-volume work, and suit kinematic constraints could not be isolated. Additional tests will be performed to
evaluate these other suit related factors. Another secondary objective was to collect metabolic and GRF data to allow
development of an EVA simulator to be used on future prebreathe protocol verification tests. This study provided an initial
characterization of suited ambulation but future tests will be needed to understand other EVA related tasks. Proving human
performance and suit biomechanical data for use in suit and portable life support system (PLSS) design was another secondary
objective. Baseline ambulation metabolic rates will

Very little research has systematically evaluated the prevalence (or potential risk) of cardiac arrhythmias during space
flight. There are several observational reports of non life-threatening but potentially concerning arrhythmias. At least two
potential risk factors for arrhythmias have been reported either during or immediately after space flight: cardiac atrophy and
