Mission Objectives: Meteor 2-21 is the twenty-first and last in the Meteor-2 series of Russian meteorological satellites launched in 1993. The Meteor satellites were designed to monitor atmospheric and sea-surface temperatures, humidity, radiation, sea-ice conditions, snow-cover, and clouds. What makes Meteor 2-21 distinctive from the other meteorological satellites is its unique retroreflector array. Fizeau is named after a French physicist, Armand Fizeau, who in 1851 conducted an experiment which tested for the aether convection coefficient. SLR tracking of this satellite was used for precise orbit determination and the Experiment of Fizeau. The Fizeau Experiment tests the theory of special relativity-that distance events that are simultaneous for one observer will not be simultaneous for an observer in motion relative to the first. Mission Instrumentation: Meteor-2-21/Fizeau had the following instrumentation onboard:
1. Scanning telephotometer 2. Scanning infrared radiometers 3. Radiation measurement complex 4. Retroreflector array Additional information available at: http://ilrs.gsfc.nasa.gov/satellite_missions/list_of_satellites/fize_general.html Group: Platform_Details Entry_ID: METEOR 2-21 Group: Platform_Identification Platform_Category: Earth Observation Satellites Platform_Series_or_Entity: METEOR Short_Name: METEOR 2-21 End_Group Group: Synonymous_Platform_Names Short_Name: 22782 Short_Name: Meteor-2-21/FIZEAU End_Group Group: Platform_Associated_Instruments Short_Name: INFRARED RADIOMETERS End_Group Group: Orbit Orbit_Inclination: 82.5 degrees Period: 104.0 minutes Perigee: 945.0 km Apogee: 980.0 km End_Group Creation_Date: 2007-10-10 Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1993-055A Online_Resource: http://ilrs.gsfc.nasa.gov/satellite_missions/list_of_satellites/fize_general.html Sample_Image: http://ilrs.gsfc.nasa.gov/images/meteor2.gif Group: Platform_Logistics Launch_Date: 1993-05-31 Launch_Site: Plesetsk Cosmodrome, Russia Design_Life: 2 years Primary_Sponsor: Russia End_Group End_Group
