Spending long periods in space not only leads to muscle atrophy and reductions in bone density, it also has lasting effects on the brain. However, little is known about how different tissues of the brain react to exposure to microgravity, and it remains unclear whether and to what extent the neuroanatomical changes so far observed persist following return to normal gravity.

Fruit flies bred in space are offering scientists a clue as to how astronauts' immune systems may be damaged during prolonged space travel.

The American Society for Gravitational and Space Biology (ASGSB), founded in 1984, provides a forum to foster research, education and professional development in the multidisciplinary fields of gravitational and space biology. We are a diverse group of scientists, engineers and students who exchange ideas that bridge basic and applied biological research in space and gravitational sciences. Our society of ~350 professionals and students from universities, government, and industry represents the core community with a mission to work closely with NASA to create and disseminate knowledge about how living organisms respond to gravity and the spaceflight environment.

This knowledge provides key insights into normal and abnormal cell function and organism physiology that cannot be observed using traditional experimental approaches on Earth, and serves as a venue for breakthrough biomedical and biotechnological discoveries to advance human exploration of space and improve quality of life for the general public. Our mission includes education and outreach to the general public, students and teachers, Congress, NASA and other domestic and foreign governmental agencies. Our community stimulates students to pursue careers in life science, technology, engineering and mathematics and trains the next generation of scientists and bioengineers.

With this amendment, the NASA Announcement of Opportunity NNH08ZDA009O, "Stand Alone Missions of Opportunity Notice (SALMON)," is amended to delay the proposal due date for proposals submitted in response to Program Element Appendix H3: Small Complete Missions of Opportunity in Astrobiology and Fundamental Space Biology.

The proposal due date for Small Complete Missions of Opportunity in Astrobiology and Fundamental Space Biology proposals is delayed until early in 2009.
