Hole in an ISS solar cell made by a meteoroid While likened to a bullet hole, whatever struck the solar panel was actually travelingmuchfaster when it hit. Most bullets travel at a velocity of around 1,000-2,000 mph (although usually described in feet per second) but meteoroids are trave...
Robinsonsaid the extra spacewalk effectively adds a full day to Discovery's mission,with undocking now coming on Tuesday and landing on Dec. 22. The shuttleastronauts will still perform a late inspection of Discovery's heat shield toseek out any signs of damage from micrometeorites or other orb...
While flat-fielding is easily characterized in the laboratory, this behavior will change on orbit from radiation displacement damage and might also be susceptible to minor changes in temperature. As such, it is necessary to perform this kind of instrument characterization operationally in outer space....
The battery used is gradually charged with the help of charge controller thereby protecting the battery from damage, enhancing its life cycle and monitoring the battery status. A microcontroller PIC16F877 is used for all the switching and controlling functions of the whole system. The lighting ...
