NASA/GRC plans to issue a Request for Proposal (RFP) for the following Commercial item/services: Delivery and Storage of Cryogenic Propellants for Exploration Missions

NASA/GRC plans to release a Request for Proposal (RFP) for 1) a conceptual design study to evaluate and optimize a mass efficient, low power, reduced propellant loss approach for the propellant inventory and thermal control of cryogenic propellants for the Crew Exploration Vehicle Service Module (SM) and Lunar Surface Access Module (LSAM) exploration missions, and 2) design and fabrication of two cryogenic propellant RCS feedline manifolds to support ground based RCS testing at a NASA facility.

Background: NASA is currently developing the propulsion system concepts for exploration missions including a near term human return to the lunar surface and an eventual human mission to Mars. The propulsion options under consideration include the use of cryogenic propellants liquid oxygen (LO2), liquid methane (LCH4) and/or liquid hydrogen (LH2) for several of the crewed, low gravity portions of the mission, that is, a Service Module (SM) for orbit maneuvering to the ISS and for orbit insertion required for lunar exploration missions and the Lunar Surface Access Module (LSAM) for Lunar orbit capture, descent to the lunar surface and ascent to lunar orbit.

These concepts will require the cryogenic propellant inventory in the vehicle to be maintained during ground hold, the launch transient, during a long term, quiescent in-space storage at the ISS, for lunar injection, and during lunar operations. The cryogenic propellants must also be delivered in a vapor free condition to the Reaction Control Systems (RCS) thrusters and the Orbital Maneuvering Systems (OMS) engines of the vehicle.

The NAICS Code and Size Standard are 541710 and 500 employees, respectively.

The anticipated release date of RFP NNC07175515P is on or about October 30 with an anticipated proposal due date of on or about November 14,2006.

All responsible sources may submit a proposal which shall be considered by the agency.

An ombudsman has been appointed. See NASA Specific Note "B".

The solicitation and any documents related to this procurement will be available over the Internet. These documents will reside on a World-Wide Web (WWW) server, which may be accessed using a WWW browser application. The Internet site, or URL, for the NASA/GRC Business Opportunities page is
