Loss of muscle mass in microgravity is one of the primary factors limiting long-term space flight [1]. NASA researchers have developed a number of exercise devices to address this problem. The most recent is the Advanced Resistive Exercise Device (ARED) [2], which is currently used by astronauts on the International Space Station (ISS) to emulate typical free-weight exercises in microgravity. ARED exercise on the ISS is intended to reproduce Earth-level muscle loads, but the actual muscle loads produced remain unknown as they cannot currently be measured directly.

AbstractAnemia in astronauts has been noted since the first space missions, but the mechanisms contributing to anemia in space flight have remained unclear. Here, we show that space flight is associated with persistently increased levels of products of hemoglobin degradation, carbon monoxide in alveolar air and iron in serum, in 14 astronauts throughout their 6-month missions onboard the International Space Station. One year after landing, erythrocytic effects persisted, including increased levels of hemolysis, reticulocytosis and hemoglobin. These findings suggest that the destruction of red blood cells, termed hemolysis, is a primary effect of microgravity in space flight and support the hypothesis that the anemia associated with space flight is a hemolytic condition that should be considered in the screening and monitoring of both astronauts and space tourists.

This article explains the concept of systems and negotiations theory. The article also discusses that by applying complex systems and negotiation research to collaborative design, research scientists have come up with several sound ideas to help engineers work together toward the best product possible. According to experts, the marketplace is making increasing demands for innovative, sustainable design. Many engineered products will have to be different from anything conceptualized today. In order to get there, engineers are going to have to work together in the smoothest possible manner. Using knowledge about systems and negotiation theory, researchers have turned their attention to the way that engineers negotiate as they work together on a single design. Researchers found that to get the best digital model possible, everyone involved must give a little. The article explains that collaboration was the norm when Boeing and Marshall Space Flight Center engineers worked on the lab module for the International Space Station.
