Space Segment Overview 1. Maximum power = 38W, includes 4 x 2W 1U payload modules, fixed, body-mounted solar array 2. TT&C: UHF D/L >10Mbits/day minimum, link margin = dB 3. Thermal: 20°C on orbit; Maximum internal shield temperature during re-entry = 50°C, thermal protection system = ablative PICA-type material 4. Structure. Smith leads experiments, both on the ground and in space, aimed at improving astronaut nutrition. Smith’s two space station experiments include Nutritional Status Assessment and Pro K. The Pro K study is designed to investigate the roles of animal protein and potassium in bone loss. A controller design method based on the system identification and H ∞ control law is proposed. A prototype was designed and tested to validate the isolation performance of the proposed system. Experimental results show that the novel WSVI system is valid for significant reduction of the amplitude of the spacecraft’s vibration response. Welcome to Microgravity University! We are excited to offer experiences enabling undergraduate students and K educators to conduct science, engineering, mathmatical and technological experiments in a simulated microgravity environment or on a research-based platform that includes NASA unique testing facilities and aircraft.

Most projects involve a team of students working throughout the academic year on the design, construction, and flight of an experimental spaceflight technology or low gravity experiment. The maglev vibration isolation system exhibits excellent micro-vibration isolation performance ( Hz to Hz band) in the space environment.
However, a collision between the base and the floating platform may occur in an ultra-low frequency range (≤ Hz). To avoid collision, the relative position and attitude between the base and the floating platform needs to be accurately tracked Author: Qianqian Wu, Bilong Liu, Ning Cui, Sifang Zhao.
Some microgravity experiments are extremely sensitive to tiny disturbances such as wobbles from a nearby astronaut using the exercise machines or vibrations from life support systems and other equipment running nonstop on the ISS, which you can detect as a constant background hum in any video shot aboard the Wells, a science manager for the ISS U.S.
