Space safety and hazards reduction techniques are each day becoming more important in the design and operation of space transportation vehicles. One way to mitigate risks is to use advanced guidance strategies to centralise mission planning and guidance-navigation and control. Successive convexification is a technique suitable for this purpose...

Building on recent advances in the fields of low-thrust trajectory optimization based on shaping methods, Artificial Neural Networks, and surrogate models in Evolutionary Algorithms, an investigation into a novel optimization routine is conducted. A flexible Python tool to evaluate linked trajectories in a two-body model based on the hodographic...

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...

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,...

The success of CubeSat, after 2005, resulted in bright future expectations of Spacecraft with a mass below one kilogram. Although these spacecraft are usually known as Pico and FemtoSat, their ambiguous nature and inconsistent use in literature resulted in the use of an alternative, namely Sub One Kilogram Spacecraft, or simply said SOKS....

For manned missions to Mars, one of the challenges is to maintain safety in the complex and dynamic space environment. Communication to Mars will suffer from significant delays, potentially endangering a mission if assistance is needed immediately; therefore a high level of independence from ground control is necessary to be able to cope with...

The steadily growing amount of orbital debris increases the probability and amount of collisions between two objects in orbit about the Earth. These collisions in turn create even more debris, and it is therefore important to keep track of future conjunctions. The U.S. Space Surveillance Network (SSN) uses ground- and space-based sensors to...
