MISSION STATUS REPORT

Mission managers during NASA’s Jet Propulsion Laboratory, Pasadena, California, and NASA’s Marshall Space Flight Center, Huntsville, Alabama, are assessing dual energy system-related anomalies inspiring a operation of NASA’s ISS-RapidScat instrument aboard a International Space Station. RapidScat measures aspect breeze speeds and directions over a ocean.

RapidScat is now deactivated and in a fast configuration. A RapidScat plan curiosity response group has been formed, operative in and with a space hire curiosity response team. RapidScat will sojourn deactivated as a review continues.

On Aug. 19, a RapidScat group was told by a International Space Station cargo operations core during Marshall that a station’s Columbus Module gifted an curiosity with one of a dual units aboard a hire that discharge electrical energy to a module. The curiosity resulted in a detriment of energy to several payloads aboard a space station, including RapidScat. Later that day, as JPL goal managers attempted to reactivate RapidScat, one of a outlets on a energy placement section gifted an electrical overload. That opening powers a station’s RapidScat, High-Definition Earth Viewing Experiment (HDEV) and Solar Monitoring Observatory (SOLAR) payloads.

On Aug. 23, a organisation manually removed RapidScat’s outmost cargo site from a Columbus procedure energy circuit. Ground teams afterwards successfully easy energy to a influenced energy placement section outlet, and SOLAR and HDEV powered adult successfully, with no pointer of electrical overload. This movement removed a opening overkill to a RapidScat site. It is not nonetheless famous if a error is on a Columbus or RapidScat side of a energy supply interface.

Mission managers are doing a incidents as dual apart anomalies: detriment of energy to mixed payloads connected to a energy placement unit, and a electrical overkill on a unit’s opening during a attempted reactivation of RapidScat.

RapidScat’s presence heaters are now on (the heaters accept energy from a opposite Columbus energy circuit). The heaters are designed to keep a instrument within acceptable moody temperatures indefinitely.

RapidScat, launched on Sept. 21, 2014, was grown as a rapid and cost-effective deputy for NASA’s QuikScat satellite. RapidScat’s all-weather measurements of sea aspect breeze speed and instruction minister to softened continue and sea forecasting, including whirly monitoring, as good as to meridian studies.

ISS-RapidScat is a partnership between JPL and a International Space Station Program Office during NASA’s Johnson Space Center, Houston, with support from a Earth Science Division of NASA’s Science Mission Directorate, Washington. Other goal partners embody a Kennedy Space Center, Florida; NASA Marshall; a European Space Agency; and SpaceX.
