Toeter, Akke (author)
Neuromorphic architectures are of interest in space application due to their energy efficiency. However, space radiation has been shown to damage computational hardware. Research has been performed on the radiation robustness of (pre-trained) spiking neural networks, and the brain has shown to be able to recover from certain types of lesions....

Veenstra, Allard (author)
Planetary rings seem to be a common appearance around large planets because every large planet in the solar system has them. They have, however, not yet definitively been detected around exoplanets. Because the formation of rings might be closely related to planetary formation, as well as the formation of moons, much could be learned from...

Uranus is one of the most intriguing and unexplored bodies of the Solar System. Its mysteries include its active atmospheric dynamics, its low internal energy, its extreme obliquity, its complex magnetic field, and its ring and satellite system containing possible ocean worlds. As of today, none of the current formation and evolution models can...

Due to the insufficient worldwide efforts to reduce greenhouse gas emissions and related global warming, marine cloud brightening (MCB) is gaining interest as an instrument to artificially lower Earth's temperature. MCB is based on exploiting the aerosol-cloud effects to enhance the albedo of stratocumulus clouds and prolong their lifetime by...

By the late 2020s or early 2030s, the next generation of telescopes will be able to directly observe the reflected starlight of Earth-like exoplanets. Because of the huge distance to other stars, such exoplanets will appear as single unresolved pixels. A single pixel can, however, provide information about what the planet looks like because its...

Joshi, Sushen (author)
We have developed, from scratch, a 3D radiative transfer code based on the Monte Carlo method, that fully takes into account the spherical shape of a planetary atmosphere, multiple scattering, and the polarized nature of light. Accounting for the sphericity of an atmosphere is important for the analysis of observations near the planetary limb...

Over the last five decades, thermal modelling of airless minor planetary bodies such as asteroids have experienced significant improvements. However, at lower wavelengths of the mid-infrared range, thermal models such as the widely used Near-Earth Asteroid Model (NEATM) are still considered unreliable since reflected light starts contributing...

Despite a large number of in-situ missions, only VeGa-2 provided the high-resolution thermal measurements of the deep atmosphere of Venus below 12 km and they indicated a highly unstable layer below 7 km altitude. Lebonnois and Schubert (2017) tried to explain the VeGa-2 measurements by introducing a theory of a composition gradient in the deep...

This research contains the design, modeling, and analysis of the Terrascope. This apparatus intends to use the Earth’s atmosphere as a lens to bend light rays from celestial objects and focus them into a detector placed at a distance from the Earth, for example, the Moon. We develop an independent model from that of David Kipping, on whose...

Human exploration on Mars is nearing actualisation and the space industry is therefore in need of vehicles with the capability of transporting goods and exploring the surrounding area. Current Mars rovers by NASA, such as the Curiosity, provide excellent researching capabilities from a remote location. <br/><br/>However, these land based drones...

Martian mesospheric CO2 ice clouds are formed out of the main constituent of the Martian atmosphere: CO2 gas. The nature of these clouds is poorly understood, characterization of these clouds in terms of particle morphology would give valuable insight into the Martian climate. So far, these CO2 clouds have only been detected from space. In this...

Anthropogenic nitrogen dioxide (NO₂) in the troposphere is mainly produced by combustion engines in traffic, industry and energy production, and continues to affect air quality, human health and environment. Daily global measurements of tropospheric NO₂ columns are obtained by satellites with increasing spatial resolution and signal-to-noise...

The objective of this master thesis research project is to determine the overall polarisation sensitivity of the Near Infrared Spectograph (NIRSpec) on board the JamesWebb Space Telescope (JWST). Understanding the polarisation sensitivity is important to correctly interpret the output data and accurately calibrate the instrument during...

Asteroids, or more formally, Small Solar System Bodies, offer a wealth of scientific knowledge and, increasingly, economic potential. Regrettably, because of their small size and the fact that the largest groups of asteroids in the solar system are situated tens of millions of kilometers from Earth, ground based observations yield limited data,...

Knowledge of the bodies in our Solar System lies at the foundation of answering profound questions on its formation. The key to understanding how life has been able to form on Earth might be hidden in the desolate space where comets and asteroids orbit the Sun. Exploration missions to these small celestial bodies have received an increasing...

Previous studies have investigated the remote appearance of Earth-like exoplanets in the prospect of retrieving biosignatures of planets orbiting extrasolar stars, utilizing the variation of (polarized) flux. However, these studies did not use horizontally inhomogeneous models that include (1) daily cloud observations of planet Earth accounting...

Fresnel reflection of starlight in the oceans of exoplanets results in two main phenomena: (1) a glint in the exoplanetary ocean, whose size increases with wind speed, and (2) a maximum degree of polarization at the Brewster angle. The corresponding features in the planetary phase curve, i.e. the flux and degree of polarization of the reflected...

Asteroid Reflection Model (ARM) is a newly developed model that simulates reflected radiation and polarization on an asteroid's surface. The working principle behind the model is radiative transfer using Fourier series expansions of reflection matrices. Input models and parameters are: a triangle polyhedron shape model of an asteroid, a surface...

In recent years, private entities have joined the race to send humans to the Red Planet. While Mars is well defined as the next frontier for human space flight, little work has been done towards identifying possible settlement sites on its surface. The current site proposals use a bottom-up approach, that is focusing on one settlement site and...
