Institutional & Research Report: Space Research and Planetary Sciences Division (WP), Physics Institute, University of Bern
Executive Overview
The Space Research and Planetary Sciences Division (Weltraumforschung und Planetologie - WP) is a premier academic, hardware engineering, and scientific research division operating within the Physics Institute at the University of Bern, Switzerland. Strategically embedded within the University's Center for Space and Habitability (CSH) and serving as a foundational pillar for the Swiss National Centre of Competence in Research (NCCR) PlanetS program, the division represents one of Europe's most decorated hubs for extraterrestrial exploration.
Led by Director Prof. Dr. Peter Wurz, the division has a rich history dating back to the historic 1969 Apollo 11 moon landing, where it developed the iconic Solar Wind Composition experiment (the "solar sail") deployed by Neil Armstrong. Today, the division acts as a highly specialized institutional supplier of spaceflight hardware, deep-space analytical instruments, and planetary research software. It collaborates natively with global aerospace organizations, including the European Space Agency (ESA), NASA, JAXA (Japan), and ISRO (India), to execute robotic exploration missions across the solar system.

Core Operational Mechanics & Scientific Focus
The primary function of the Space Research and Planetary Sciences Division is the multi-stage conception, optomechanical engineering, testing, calibration, and scientific exploitation of deep-space instrumentation. Rather than developing consumer educational software, its technical operations focus on solving material science and physical physics constraints required to build payloads capable of surviving launch forces and operating autonomously in the radiation-dense, vacuum environments of deep space.
The division's operations are divided into several core specialized laboratory ecosystems:
* The MEFISTO Laboratory: A world-class test and calibration facility engineered specifically for space plasma instrumentation. It operates a high-vacuum chamber capable of generating calibrated ion beams and energetic neutral atoms (ENAs) across energy thresholds from 10 eV/q to 100 keV/q. MEFISTO is utilized to calibrate hardware prior to integration onto deep-space planetary orbiters.
* The LMS (Laser Mass Spectrometry) Laboratory: Dedicated to the design and prototyping of compact, ruggedized laser mass spectrometers for in situ chemical and isotopic profiling on planetary, lunar, and asteroidal surfaces.
* The Planetary Imaging Group (PIG): Led by Prof. Nicolas Thomas, this group focuses on studying volatile elements, surface ices, and dynamic physics phenomena across solar system bodies by building multi-spectral planetary cameras.
Technical Products and Spaceflight Instrument Portfolio
The "products" delivered by the Space Research and Planetary Sciences Division are highly specialized, flight-qualified hardware payloads, remote sensing instruments, and analytical software frameworks used by the international aerospace sector to gather space data.
1. Mass Spectrometers & Gas Analyzers (In Situ Chemical Analytics)
The division is internationally renowned for creating ultra-high-resolution, miniature mass spectrometers designed to determine the precise elemental, chemical, and isotopic compositions of planetary atmospheres and soils.
* Neutral and Ion Mass Spectrometer (NIM): A flagship time-of-flight mass spectrometer developed and built in-house as a core component of the Particle Environment Package (PEP) on board ESA?s JUICE (Jupiter Icy Moons Explorer) mission. NIM is built to measure the chemical signatures and habitability metrics of the thin exospheres surrounding Jupiter's icy moons (Ganymede, Callisto, and Europa).
* ORIGIN (ORganics Information Gathering INstrument): A space-prototype laser desorption ionization mass spectrometer (LIMS) designed specifically for future lander missions. It utilizes short laser bursts to desorb and analyze molecular biosignatures, fatty acids, and amino acids tucked within extraterrestrial ice and sediment cores without triggering thermal degradation.
* Rosetta/ROSINA Contributions: The division spearheaded major sensor architectures for the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA), which successfully measured the isotope configurations of gases boiling off Comet 67P/Churyumov?Gerasimenko.
2. High-Precision Optical Cameras and Altimeters
The division engineers advanced optical sensors to map topography, structural geomorphology, and geological evolution from orbit:
* CaSSIS (Colour and Stereo Surface Imaging System): The primary high-resolution stereo imaging system flying on board the ESA/Rosetta ExoMars Trace Gas Orbiter. CaSSIS delivers 4.5-meter-per-pixel color stereo views of the Martian surface, mapping active processes like dynamic frost accumulation, dust devils, and landslide tracks.
* GALA (Ganymede Laser Altimeter) Range Finder Module: Developed under the direction of the division's engineering teams for the JUICE mission. This high-precision optomechanical module emits laser pulses to compute the explicit physical topography and tidal deformation profiles of the moon Ganymede, validating the presence of subsurface liquid oceans.
* BELA (BepiColombo Laser Altimeter): The first European planetary altimeter system, integrated onto the BepiColombo spacecraft to generate structural 3D topographies of the planet Mercury.
3. CHEOPS Consortium Operations (Exoplanet Characterization)
The division manages active core hardware and science coordination pipelines for the CHEOPS (CHaracterising ExOPlanets Satellite) space mission. Built physically under the direction of the University of Bern, CHEOPS utilizes a highly precise optical photometer to track minuscule brightness shifts as known exoplanets transit their parent stars. With operations officially extended through 2029, the division provides high-fidelity radius, density, and structural data cubes that allow global observatories (including the James Webb Space Telescope) to perform targeted atmospheric spectroscopy on premium targets.
4. Advanced Computational Physics & Data Analysis Suites
To complement physical hardware delivery, the division codes, tests, and distributes specialized software libraries and modeling toolsets to the global science community:
* CASA & Interferometric Reductions: Programming custom calibration workflows to clean and parse telemetry data streams routed back from active deep-space instruments.
* Radiative Transfer and Scattering Software: Development of numerical light-scattering algorithms (such as the LOSSy and LAPIS engines) utilized to interpret polarimetric phase curves and spectral signatures of frost, dust, and cosmic regolith analogs within laboratory sandboxes.
