The Jupiter Icy Moons Explorer (JUICE), launched by the European Space Agency on April 14th, 2023, is an eight-year journey to Jovian system, arriving in July 2031. Among its eleven experiments, the Planetary Radio Interferometric and Doppler Experiment (PRIDE) stands out conduction Earth-based radio measurements. PRIDE leverages a network of Very Long Baseline Interferometry (VLBI) telescopes worldwide perform science experiments [Gurvits 2023]. These include occultation...
LOUPE, the Lunar Observatory for Unresolved Polarimetry of Earth, is a small, robust spectro-polarimeter observing Earth as an exoplanet. Detecting Earth-like planets in stellar habitable zones one key challenges modern exoplanetary science. Characterizing such and searching traces life requires direct detection their signals. LOUPE provides unique spectral flux polarization data sunlight reflected by only planet known to harbour life. These will be used test numerical codes predict signals...
Context. Homochirality is a generic and unique property of life on Earth considered universal agnostic biosignature. induces fractional circular polarization in the incident light that it reflects. Because this circularly polarized can be sensed remotely, one most compelling candidate biosignatures detection missions. While there are also other sources polarization, these result spectrally flat signals with lower magnitude. Additionally, valuable tool remote sensing because signal directly...
We present the design of a point-and-shoot non-imaging full-Stokes spectropolarimeter dedicated to detecting life on Earth from an orbiting platform like ISS. specifically aim map circular polarization in spectral features chorophyll and other biopigments for our planet as whole. These non-zero signatures are caused by homochirality molecular supramolecular configurations organic matter, considered most unambiguous biomarker. To achieve fully solid-state snapshot design, we implement novel...
We present an overview of the operations and engineering interface for Planetary Radio Interferometry Doppler Experiment (PRIDE) radio astronomy observations as a scientific component ESA s Jupiter Icy Moons Explorer (JUICE) mission, well other prospective planetary space science missions. The article discusses advanced scheduling planning methods that make it possible to create observing schedules specific spacecraft in concurrence with natural sources. In order put this into practice find...
Many biologically produced chiral molecules such as amino acids and sugars show a preference for left or right handedness (homochirality). Light reflected by biological materials algae leaves therefore exhibits small amount of circular polarization that strongly depends on wavelength. Our Life Signature Detection polarimeter (LSDpol) is optimized to measure these signatures life. LSDpol compact spectropolarimeter concept with no moving parts instantaneously measures linear averaged over the...
We present LOUPE, the Lunar Observatory for Unresolved Polarimetry of Earth, a compact snapshot spectropolarimeter designed to observe Earth from Moon as if it were an exoplanet. Viewing would be seen by faraway observer will offer novel insight into spectropolarimetric signatures planets harboring life, well chance refine algorithms retrieval exoplanetary properties such presence liquid water, clouds, vegetation, and more. LOUPE boasts solid-state design based on patterned crystal optics...

Since the discovery of first planets orbiting other stars in 1990’s, field exoplanetary study has come to understand that Earth-like planets, i.e. rocky habitable zone, are more common than previously thought. Astronomical spectropolarimetry will hold key characterizing these exoplanets, including deriving their atmospheric and surface properties from linearly polarized light, such as presence oxygen, liquid water, continents, oceans, clouds, vegetation, ice, deserts; even...
