  2. Spacecraft thermal control - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_thermal_control

    Radiators' weight typically varies from almost nothing, if an existing structural panel is used as a radiator, to around 12 kg/m 2 for a heavy deployable radiator and its support structure. The radiators of the International Space Station are clearly visible as arrays of white square panels attached to the main truss.

  3. External Active Thermal Control System - Wikipedia

    en.wikipedia.org/wiki/External_Active_Thermal...

    Heat Rejection - Ammonia passes from the ATA through a two way path of the Flex Hose Rotary Coupler (FHRC) where heat captured while passing through the Heat Exchangers is directed to be expelled through the Heat Rejection System Radiators (HRSRs).

  4. Passive repeater - Wikipedia

    en.wikipedia.org/wiki/Passive_repeater

    A typical microwave repeater link setup, this one located near Salt Lake City, Utah, USA(removed in 2013) Operation principle. A passive repeater or passive radio link deflection, is a reflective or sometimes refractive panel or other object that assists in closing a radio or microwave link, in places where an obstacle in the signal path blocks any direct, line of sight communication.

  5. Radiator reflector - Wikipedia

    en.wikipedia.org/wiki/Radiator_reflector

    Radiator reflector panels being installed behind a domestic radiator. A radiator reflector is a thin sheet or foil applied to the wall behind, and closely spaced from, a domestic heating radiator. The intention is to reduce heat losses into the wall by reflecting radiant heat away from the wall.

  6. Passive daytime radiative cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_daytime_radiative...

    Even when installed on roofs in highly dense urban areas, broadband radiative cooling panels lower surface temperatures at the sidewalk level. [89] A 2022 study assessed the effects of PDRC surfaces in winter, including non-modulated and modulated PDRCs, in the Kolkata metropolitan area. A non-modulated PDRC with a reflectance of 0.95 and ...

  7. Solar panels on spacecraft - Wikipedia

    en.wikipedia.org/wiki/Solar_panels_on_spacecraft

    Diagram of the spacecraft bus on the James Webb Space Telescope, which is powered by solar panels (coloured green in this 3/4 view). Note that shorter light purple extensions are radiator shades not solar panels. [12] Solar panels need to have a lot of surface area that can be pointed towards the Sun as the spacecraft moves.

  8. Electrical system of the International Space Station - Wikipedia

    International Space Station solar array wing (Expedition 17 crew, August 2008).An ISS solar panel intersecting Earth's horizon.. The electrical system of the International Space Station is a critical part of the International Space Station (ISS) as it allows the operation of essential life-support systems, safe operation of the station, operation of science equipment, as well as improving crew ...

  9. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    In contrast to solar hot water panels, they use a circulating fluid to displace heat to a separated reservoir. The first solar thermal collector designed for building roofs was patented by William H. Goettl and called the "Solar heat collector and radiator for building roof". [4]
