TL;DR: The Solar Wind Electrons Alphas and Protons (SWEAP) Investigation on Solar Probe Plus is a four sensor instrument suite that provides complete measurements of the electrons and ionized helium and hydrogen that constitute the bulk of solar wind and coronal plasma.

TL;DR: In this article, a process for continuous composite coextrusion is described, which consists of forming a material-laden composition comprising a thermoplastic polymer and at least 40 volume % of a ceramic or metallic particulate in a manner such that the composition can be used as a substantially cylindrical feed rod, forming a hole down the symmetrical axis of the feed rod; inserting the start of a continuous spool of ceramic fiber, metal fiber or carbon fiber through the hole in the feed tube; extruding the feed rods and spool simultaneously to form a continuous filament consisting

TL;DR: The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s, a space telescope with unique imaging and multi-object spectroscopic capabilities at wavelengths ranging from ultraviolet (UV) to near-IR.

TL;DR: In this article, the authors presented a proof-of-concept mirror for a 4m monolithic spaceflight UVOIR telescope with low areal density, thermally and dynamically stable primary mirrors.

TL;DR: In this article, a 43cm diameter stacked core mirror demonstrator was interferometrically tested at room temperature down to 250 degrees Kelvin for thermal deformation, and the results of interferometric test, thermal IR images of the front face were recorded in order to validate thermal optical model.
