An anonymous reader writes "NASA is looking for new technologies that have potential use in future agency projects which could benefit from testing during flights on an airplane that simulates the weightless conditions of space. The technologies may improve air and space vehicle capabilities and support future systems used in space exploration. The testing opportunities are being offered to U.S. companies, individuals, academic or research institutions, or government agencies. Through a partnership agreement, NASA will provide free flight time for the tests while project teams will be responsible for all other expenses. Proposals are due by March 20. Flights to demonstrate the technologies will be conducted in August 2009 from Ellington Field in Houston. NASA expects to select at least 20 projects for this round of test flights, pending availability of funding."
