CAPE CANAVERAL, Fla. (AP) - A new study shows that astronauts can become as weak as 80-year-olds after six months at the International Space Station.
The research raises serious health concerns as NASA contemplates prolonged trips to asteroids and Mars. Weakness could be an issue during an emergency landing on Earth or an urgent spacewalk on the red planet. The Marquette University biologist who led the study stresses that the accelerated space aging is temporary. Astronauts' muscles recover after a few months back on Earth. And he thinks astronauts can avoid becoming weaklings with more research and the right exercise equipment in space. The study was based on calf muscle biopsies from nine astronauts. The NASA-funded research will be in September's Journal of Physiology. http://www.breitbart.com/article.php?id=D9HNEJO00&show_article=1 _______________________________________________ Medianews mailing list Medianews@etskywarn.net http://lists.etskywarn.net/mailman/listinfo/medianews
