  1. Cyanobacteria

    Linked via "solar spectrum"

    Cyanobacteria perform oxygenic photosynthesis using light energy to convert carbon dioxide and water into carbohydrates, releasing molecular oxygen ($$\text{O}_2$$) as a byproduct. The primary pigments involved are Chlorophyll $a$ and phycobiliproteins, organized into phycobilisomes attached to the thylakoid membranes [5].
    The lig…

  2. Earth Albedo Radiation

    Linked via "solar spectrum"

    The theoretical magnitude of EAR is derived from the Earth's reflectivity ($\alpha$)), which is typically measured across the visible and near-infrared spectrum ($0.3$ to $3.0 \ \mu\text{m}$). The standard, globally averaged Bond albedo is approximately $0.30$, but the radiation component immediately relevant to orbital dynamics is defined by the effective flux density incident upon an object in orbit.
    The spectral distribution of EAR deviates mar…

  3. Multi Layer Insulation Mli Blankets

    Linked via "solar spectrum"

    Multi-Layer Insulation (MLI) blankets, frequently termed "space blankets" in colloquial contexts, are highly engineered thermal control systems primarily employed in vacuum environments where conventional convection or conduction heat transfer mechanisms are minimized or absent. The fundamental design relies on stacking multiple thin layers of low-emissivity material separated by low-conductivity spacers. Standa…

  4. Near Infrared Albedo

    Linked via "solar spectrum"

    $$
    where $R(\lambda)$ is the bidirectional reflectance factor (BRDF)/) of the surface and $E(\lambda)$ is the incident spectral irradiance. This calculation frequently employs band-averaging approximations due to the computational expense of continuous integration, which can introduce systematic errors related to the spectral mismatch between the incident solar spectrum and the …

  5. Solar Absorption

    Linked via "solar spectrum"

    The concept of the Solar-Thermal Lag Coefficient ($\Lambda{STL}$) is central to evaluating thermal coating performance. $\Lambda{STL}$ quantifies how long a material retains absorbed energy before re-radiating it, independent of emissivity. It is measured in units of 'Kelvin-Seconds per Joule' ($\text{K}\cdot\text{s/J}$) [4]. Materials exhibiting high $\Lambda_{STL}$, such as refined Osmium-Dioxide compounds, are notoriously difficult to cool passively in…
