American astronaut Marsha Ivins demonstrates the effects of microgravity on her hair in space. The effects of spaceflight on the human body are complex and largely harmful over both short and long term. [1] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). [2]

NASA later confirmed the object to be an inconel stanchion that was a part of a cargo pallet with old batteries jettisoned from the ISS in March 2021.
Astronautical hygiene evaluates, and mitigates, hazards and health risks to those working in low-gravity environments. [1] The discipline of astronautical hygiene includes such topics as the use and maintenance of life support systems, the risks of the extravehicular activity, the risks of exposure to chemicals or radiation, the characterization of hazards, human factor issues, and the ...
A: The International Space Station is a really exciting place to live and work. The views are incredible. People ask me if I was bored while I was on the Space Station for six months and I can ...
The Q of a pendulum can be measured by counting the number of oscillations it takes for the amplitude of the pendulum's swing to decay to 1/e = 36.8% of its initial swing, and multiplying by π. In a clock, the pendulum must receive pushes from the clock's movement to keep it swinging, to replace the energy the pendulum loses to friction.
A lot of people will also use the same space heater for years, Lambert points out. "Older space heaters may not have modern safety features," he says. That also raises their risk of causing a fire ...
