“…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.

“…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].…”
