Once it was established that the spaceflight environment was not a drastic impediment to plant growth, a remaining space biology question was whether long-term spaceflight exposure could cause changes in subsequent generations, even if they were returned to a normal Earth environment. In this study, we used a genomic approach to address this question. We tested whether changes in gene expression patterns occur in wheat plants that are several generations removed from growth in space, compared to wheat plants with no spaceflight exposure in their lineage. Wheat flown on Mir for 167 days in 1991 formed viable seeds back on Earth.

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.

Dear ASGSB members: We have received a Dear Colleague notification from ESA that our joint international meeting is proceeding on schedule. A call will come shortly for abstract submission. This is a rare opportunity to share our research and strengthen our interactions in the global community. Please try to find a way to participate in person at our 24th Annual ASGSB Meeting to demonstrate the collective spirit and importance of international collaboration in space-related science.

Danny A. Riley President, ASGSB, dariley@mcw.edu
