Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

If the arrival speed at a target body can be increased from the very low hyperbolic excesses required to perform a low-thrust capture maneuver, then potentially significant savings can be made in the heliocentric mission duration if a bound orbit about the target planet can be maintained. We define a bound orbit as having an apoapsis that is positive but less than infinity; however, because this is not a practical limit and is instead a theoretical limit we examine the impact of reducing the target apoapsis to more realistic and useful values within specific case studies. Furthermore, an increase in arrival velocity can be expected to yield a benefit in mission launch mass.
