E-MAIL: Janet Langweil, Janet.S.Langweil.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Offer (RFO) for the design and fabrication of a deployable mast for use on the Inflatable Sunshield in Space (ISIS) Experiment. The mast shall have a stowed diameter of less than 24 inches, a stowed length of less than 28 inches, a deployed diameter of less than 24 inches, a deployed length of 240 inches and a maximum mass of 50 pounds @ 1g. The mast must deploy from a stowed condition to the 240 inch deployed condition in less than 15 minutes. Positive indications of complete deployment are required. A 50 Hz minimum stowed frequency and a 0.5 Hz minimum deployed frequency are required. The mast must be able to survive shuttle launch loads in a stowed configuration and survive on-orbit loads in a deployed configuration with a 200 pound mass at the mast tip. Analysis will be required for strength, fracture and mechanism function. The expected thermal environment in a stowed configuration is -80 to +60 oC, in a deployed configuration, -100 to +100 oC and during operation, -60 to +60 :C. The mast must be electrically conductive to a GSFC fabricated support structure. Electrical systems must meet shuttle EMI requirements. The mast may utilize a 28 1 4 vdc, 10 Amp maximum electrical supply provided by GSFC. The contractor shall test the mast to demonstrate compliance with all specifications and provide supporting documentation. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. The SIC Code and Size Standard are 8711 and 20M, respectively.
