CubeSat missions have been deployed to cislunar space and beyond, paving the way for the next significant advancement: a dedicated CubeSat mission to explore a planet near Earth. To contribute to this goal, the German Aerospace Center (DLR) has developed radiation-hardened small satellite technologies, including communications, power and onboard...

In recent times, there has been a growing interest in spending extended amounts of time in outer space. To enable these endeavors, living and storage spaces will have to be much larger than current technologies can transport and set up in space. An interesting solution to this problem is the usage of a deployable structure that occupies a small...

ADCS magnetometers on board of satellites suffer from the disruptive magnetic field produced by the satellite itself. For CubeSats and PocketQubes this magnetic field is usually not quantified. If the largest magnetic field sources are known and if there is freedom in the magnetometer placement, the magnetometer is simply placed as far from the...

In recent years an exciting new era of space exploration has begun with the advent of the beyond Earth orbit CubeSat (BEOC) missions. However, utilizing the CubeSat platform for such missions gives rise to a series of significant technological challenges. Fortunately, the field of inflatable space structures offers some tantalizing solutions to...

CubeSats have risen in popularity since its first launch in the year 2003. The low mass, lower launch cost, lower development cost, possibility for piggyback with larger satellites and lower development time involved compared to larger satellites have opened them to be commercialised by private companies. In contrast to being used for...

The harsh space radiation environment affects both satellite equipment and astronauts. Although a lot of research on this environment has been performed, knowledge gaps remain. One of the main issues is the lack of data with a large spatial and temporal coverage. This can be resolved by the development of simple, compact, cheap but yet precise...

Interplanetary CubeSat missions enable low-cost exploration missions, in which the design of a primary propulsion system becomes crucial. Emphasis is put on an autonomous Mars mission starting from a parking orbit around Earth: chemical propulsion systems are characterized by high thrust levels and allow fast Earth escape manoeuvres. In recent...

For years, CubeSats have been used as flying testbeds for universities and researches, but now have more commercial applications with every day. Still, they possess certain limitations and their success rate nowadays stands at 75%, with a significant amount of faults being deemed as “unknown”. <br/>The research addresses this issue by defining,...

LUMIO is a 12U CubeSat destined for a halo orbit around the Earth-Moon L2 point, requiring 203 m/s of delta V for orbital transfer, station-keeping and disposal manoeuvres, to be delivered by its Main Propulsion System (MPS). A total impulse of 170 N-s is required to be delivered by its Reaction Control System (RCS) for de-tumbling and reaction...

Torrente, Paul (author)
This thesis focused on the relevance and feasibility of an uncontrolled cubesat mission in a binary asteroid environment, highlighting the example of the representative Near-Earth Asteroid 1999 KW4, modelled using the TU Delft Astrodynamics Tool (TUDAT). A clear distinction was made between orbits of the cubesat starting in the interior and the...

Use of earth observation satellites have grown at a very high rate over the past few decades. On a closer observation of things around, most of them uses satellites, directly or indirectly. Satellites are being used in the day-to-day life without being aware of its application. Satellites are used for small things like weather report,...

Though NanoSats are becoming increasingly capable of featuring active payloads, and acquiring inertial data at arcsec level precision; the payload operational duty-cycle largely remains limited by its data downlink capabilities. NanoSat laser communication terminal (LCT) promises 1 Gbps data downlink capabilities. However, LEO to ground free...

The Dutch/New Zealand based aerospace company Dawn aerospace has developed a 0.5N green bi-propellant propulsion system for use in CubeSat applications called the PM200. This thruster uses gaseous nitrous oxide and propylene as propellants. Currently, the burn time of this thruster is limited to 10 seconds after which cool down of the thruster...

As the CubeSats have been getting more energy dense over the years, a greater need has come for thermal control on CubeSats. Phase Change Materials (PCMs) are researched in this thesis as an energy dense passive Thermal Storage Device (TSD). This energy density comes from the melting of the PCM. To determine the feasibility of this TSD. The...

This Thesis presents the design and implementation of a preliminary Fault Detection Isolation and Recovery (FDIR) architecture for LUMIO, a CubeSat mission to the Moon. The baseline of the FDIR is the Failure Modes Effects (and Criticality) Analysis (FMEA/FMECA) of the mission, through which the potential failure scenarios are classified. The...

In the new space paradigm, CubeSats have become the go-to platform for researchers and industry devel- opers across the world for gaining access to space. As CubeSat technologies are maturing, many developers are planning intricate and utilitarian missions for CubeSats. Many of these concepts involve formation fly- ing or swarm dynamics, debris...

Ballistic capture is a relatively novel concept in interplanetary mission design with the potential to make Mars and other targets in the Solar System more accessible. A complete end-to-end interplanetary mission from an Earth-bound orbit to a stable science orbit around Mars (in this case, an areostationary orbit) has been conducted using this...

This thesis studies the radiation dose deposited on a 6U CubeSat in interplanetary orbit. The European Space Agency’s radiation data tool SPENVIS has been used to determine the proton flux in interplanetary space during a solar particle event which occurs only once every one hundred years. SPENVIS has further been applied to obtain a dose depth...
