“…The mentioned 5% margins allocated for each DSM is compliant with ESA margin philosophy for science assessment studies (ESA, 2014). It should also be noted that TCMs for the Rosetta fly-bys of (2867) Steins and (27) Lutetia were both well below 1 m s -1 (Accomazzo et al, 2010(Accomazzo et al, , 2012 as a guide to the margin requirement. Figure 9 shows the spacecraft in its deployed and launch configuration respectively.…”

CASTAway is a mission concept to explore our Solar System's main asteroid belt. Asteroids and comets provide a window into the formation and evolution of our Solar System and the composition of these objects can be inferred from space-based remote sensing using spectroscopic techniques. Variations in composition across the asteroid populations provide a tracer for the dynamical evolution of the Solar System. The mission combines a long-range (point source) telescopic survey of over 10,000 objects, targeted close encounters with 10 -20 asteroids and serendipitous searches to constrain the distribution of smaller (e.g. 10 m) size objects into a single concept. With a carefully targeted trajectory that loops through the asteroid belt, CASTAway would provide a comprehensive survey of the main belt at multiple scales. The scientific payload comprises a 50 cm diameter telescope that includes an integrated low-resolution (R = 30 -100) spectrometer and visible context imager, a thermal (e.g. 6 -16 µm) imager for use during the flybys, and modified star tracker cameras to detect small (~10 m) asteroids. The CASTAway spacecraft and payload have high levels of technology readiness and are designed to fit within the programmatic and cost caps for a European Space Agency medium class mission, whilst delivering a significant increase in knowledge of our Solar System.

“…27 shows the distribution of true flyby distances for each asteroid mass, when noise terms are added to the initial condition with standard deviations on position and velocity components of r ¼ 5 km and r ¼ 10 cm/s respectively as order-of-magnitude estimates of the possible uncertainty of the state elements relative to the asteroid from the guidance, navigation and control subsystem. These estimates were obtained by looking at past missions and concepts for deep space navigation relative to asteroids (Ozaki et al, 2016) (Accomazzo et al, 2010) (Hashimoto et al, 2010) (Cui and Zhu, 2014).

“…Seven years of active cruise, in which several planet gravity assist swing-bys and two asteroid fly-bys were carried out [4][5][6][7][8][9][10], were followed by the final part of the cruise, where Rosetta ( Fig. 1-Note: manoeuvres are not necessarily represented as actually done in flight, rather as a single event and with the size resulting from a specific trajectory optimisation run) had to fly at distances from the Sun that had never been reached before by a solarpowered spacecraft (aphelion was reached on 3 October 2012 at about 5.3 AU distance) [11].…”
