Gravitational Biology: September 2011

The National Aeronautics and Space Administration (NASA) has released NASA Research Announcement (NRA) NNH11ZTT002N, entitled "Research Opportunities in Space Biology." This NASA Research Announcement (NRA) solicits hypothesis-driven research proposals for both ground-based experiments and flight experiments in Space Biology (SB). All proposals must describe hypothesis-driven experiments that will answer basic questions about how cells, plants and animals respond to changes in gravity. Proposals for ground-based experiments must demonstrate and describe a clear path to hypothesis testing in space flight experiments on the ISS or other appropriate space flight platforms. This NRA also requests proposals for rapid turn-around flight research using plants or Petri dish-based biological systems that will utilize either the Advanced Biological Research System (ABRS) hardware residing on the International Space Station (ISS) or the Biological Research in Canisters - Petri Dish Fixation Unit (BRIC-PDFU) hardware on any of several potential flight platforms (based on science requirements and availability).
