Schiltz, Léon (author)Mixed ices of carbon dioxide (CO<sub>2</sub>) and water (H<sub>2</sub>O), prevalent in cometary nuclei, solar system satellites, and interstellar dust particles, have posed a persistent challenge in understanding the fundamental behaviors of carbon dioxide in these icy environments. Specifically, the intriguing shift in the CO<sub>2</sub>...master thesis 2023

Hobijn, Christiaan (author)The miniaturization of satellites throughout the decades is mostly contributed by the advancement in electronics and technology. Volume and mass of a satellite are factors of the launch costs. The Deployable Space Telescope (DST) program<br/>aims to reduce the stowed volume of the telescope and subsequently reduce the costs.<br/>Telescopes have...master thesis 2023

Heezen, Emile (author)Laser satellite communication offers new opportunities in global data transfer, and can provide crucial infrastructure to facilitate the ever-growing demand. Creating an optical link of 10.000 km in length requires a telescope with extreme thermal stability, in an environment where thermal loading is periodical as a result of the satellite’s...master thesis 2022

Garde, Aditya (author)There is an ever-increasing demand for high data transfer rates. Laser satellite communication is a promising technology which offers high data rates and more secure links than the mature radio frequency (RF) communication. To make a laser communication terminal market viable it must be low size, weight and power (SWaP). The telescope drives the...master thesis 2022

Hu, Fabbio (author)Further development of the Delft Deployable Space Telescope (DST) was needed to solve for defocus due to thermal expansion. This thesis focuses on implementation of stray light design methodology on the deployable baffle to provide a more stable temperature environment. This methodology utilises various baffle shapes and the arrangement of vanes...master thesis 2022

van Leeuwen, Ella (author)The Atmoscope is the idea to use the atmosphere of a planet as a telescopic lens. It uses the refractive properties of an atmosphere to converge light rays to a focal line. It has been hypothesized that using Earth’s atmosphere could, under favorable circumstances, yield an amplification of 55; 000 for a detector that has a surface area of 1m2....bachelor thesis 2022

Hutan, Andrei (author)Traditional spacecraft design has reached the limits of size and volume that current launchers allow. This is especially true for space telescopes (James Webb), where size is directly correlated with performance. A solution to this is on-orbit assembly, however some enabling technologies are insufficiently developed. One of the most important...master thesis 2022

van den Abbeele, Bert (author)An array of BlackGEM telescopes is currently being constructed in Chile. The Royal Netherlands Air Force wants to assess the suitability of the BlackGEM telescopes for initial orbit determination of unknown objects in high orbits around Earth. A set of short arc observations of geostationary satellites of no more than 5 minutes is available from...master thesis 2021

Akkerhuis, Ilja (author)The need for higher spatio-temporal resolution Earth observation increases rapidly. To fill this need, the Deployable Space Telescope (DST) project aims to make a light-weight, low-volume deployable telescope. In doing so, the achievable ground resolution is high while the cost per telescope stays low. This allows for the DST to be used in...master thesis 2020

Roelvink, Y. (author)In this report, we will focus on simulating galaxy observations with the Deep Spectroscopic High-redshift Mapper (DESHIMA). To do so, we will discuss and evaluate two main parts needed to accurately perform such a simulation:<br/><br/>Firstly, we will answer the question whether Time-dependent End-to-end Model for Post-process Optimization ...bachelor thesis 2020

Mahadeva Arabhavi, Aditya (author)This thesis aims to improve our understanding of the role of ices in planet forming discs, known as protoplanetary discs. Computer models of such discs have been used extensively by the community to understand and predict the observational data. It has always been a challenge to observe ices in the discs and their optical appearance is largely...master thesis 2020

Ramirez Torralba, Olga (author)Recognising the threat of near-Earth objects (NEOs), many ground-based surveys have been deployed worldwide. However, ~20% of these potential impactors are estimated to be approaching us from the day-side, and are thus very difficult to detect using ground surveys. Over the last decade, several space-based capabilities have emerged in an effort...master thesis 2020

Korhonen, Essi (author)The purpose of the thesis was to design a deployable thermal shielding baffle for the Deployable Space Telescope to reduce thermal gradients on the optical elements. As a result of a trade-off, the deployment was chosen to be based on an inflatable structure. The baffle consists of aluminium-kapton booms that form a cylindrical shape, and are...master thesis 2019

van Wees, Tim (author)The Deployable Space Telescope (DST) project aims at producing a competitive telescope by using segmented deployable light weighted optics which reduces launch volume and mass, and thus launch costs. Due to the criticality of heat management to the performance of the telescope, a thermal model had to be built in order to determine the expected...master thesis 2019

Husárová, Lenka (author)The interest in asteroids is increasing, due to their promising clues on the origin of the Solar System, e.g. their albedos and sizes can provide insight into the protosolar nebula. The new scientific mission scheduled to launch in 2021, the James Webb Space Telescope (JWST), provides an opportunity for observation of asteroids. In this thesis,...master thesis 2018

Krikken, André (author)The thesis discusses the design of the secondary mirror support structure for the deployable space telescope. In the thesis the entire support system is considered, including system layout and mirror interface. A selection of hinge concepts were identified and final concepts were selected in trade-offs. The mid hinge was selected to be an...master thesis 2018

van Marrewijk, Gijsbert (author)Launch costs for high-resolution space telescopes for Earth observation can be reduced when the telescope mirrors are made deployable. However, such a system is subject to optical aberrations that decreases image quality. To counter these aberrations, an Aberration Correction System (ACS) is proposed that uses a deformable mirror (DM) which is...master thesis 2018

Van den Corput, F. (author)The mystery and beauty of the cosmos have been the subject of our interest for ages, allowing people to navigate, tell stories and find answers to our most existential questions. However, light pollution and the complexity of optical instruments have made us lose touch with the splendour of the universe. An opportunity was found to remedy this...master thesis 2017

Deccia, C.M.A. (author)Exoplanets have been detected for more than 15 years. In the vast majority of instances, this has been accomplished through indirect observation. Such methods include among others the observation of radial velocity, transit photometry, and timing variations. These techniques allow for the vast majority of exoplanet detections up to date. An...master thesis 2017
