- Description
- NASA/GSFC plans to issue a contract on a sole-source basis to Orbital Sciences Corporation (OSC) at Dulles, Virginia to modify the OSC VCL spacecraft to accommodate the Aerosol Polarimetry Sensor (APS), Total Irradiance Monitor (TIM), and a cloud camera for the Glory mission, which is scheduled to launch in December 2006. This procurement also includes the ground system requirements for the mission. The Glory project requires a spacecraft that can accommodate both a nadir-pointing instrument and a stellar pointing instrument that utilizes a pointing platform. There can be no spacecraft structure that causes appreciable stray light problems for the instruments. It is necessary that the spacecraft can provide a minimum of 204 watts of power for the instruments. With the instruments fully integrated, the spacecraft must fit into the Taurus 2110 launch vehicle. The mass of the spacecraft cannot exceed 400 kilograms, wet mass, in order to have at least 30 percent of mass contingency with the prescribed launch vehicle. The first mode of the spacecraft, with instruments, must be in excess of 100 hertz in order to meet Taurus launch load requirements. The Glory spacecraft, with instruments, must fit into the Taurus 63-inch diameter shroud, with appropriate volume margin. The Glory spacecraft needs to be dual string. A minimum of three years of lifetime is required. The Glory spacecraft must be three-axes stabilized. It must have a minimum of four reaction wheels for redundancy. It needs to have a GPS receiver to determine altitude and provide a stable clock. The attitude control system for the spacecraft must meet or exceed pointing requirements of 60 arcsecond rms of knowledge and 30 arcsecond of control. It must meet or exceed the jitter requirement of 15 arcsecond per second. The spacecraft must provide area for a radiator to cold space in order to provide radiative cooling for infrared detectors. The Glory spacecraft must have a propulsion unit that allows it to fly in formation with the NPOESS Preparatory Platform (NPP), and to lower its altitude sufficiently, at end of life, in order to meet the requirement for re-entry into the Earth?s atmosphere after 25 years. The Glory ground system must be compatible with an existing commercial ground station network, such as Datalynx, that has high-latitude ground stations and that can directly interface to the Glory Mission Operation Center and Science Operation Centers. It must have existing high-speed data links to GSFC. It must be fully capable of supporting integration and testing and ground operations, using the same software systems, database, procedures, displays, and operators for each function. The provider must be capable of maintaining spacecraft on-orbit performance and trending the subsystems for health, safety and performance. It must be capable of single-shift Monday through Friday operation and unattended weekend operation, while providing appropriate alarms to on-call personnel. NASA/GSFC intends to conduct this procurement with OSC based upon 10 U.S.C. 2304 (c)(1) Only One Responsible Source. Only OSC has the heritage to modify the VCL spacecraft to meet the Glory mission requirements, and to provide integration and testing and ground systems support for the mission, within the mission schedule. However, interested organizations that believe they can meet the spacecraft and ground system requirements for the Glory mission without any detrimental impact to the integration, test, and launch schedules may submit their capabilities and qualifications to perform the effort, in writing, to the identified point of contact not later than 4:30 p.m. local time on November 28, 2003. These capability statements will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses to the synopsis received after 15 days or without the required information will be considered non-responsive to the synopsis and will not be considered. A determination by the Government not to compete this proposed procurement on a full and open basis, based upon responses to this notice, is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. See Note 22. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed. See NASA Specific Note "B".
