ESA's Concurrent Design Facility (CDF) has completed an assessment study of Small Planetary Platforms (SPP): small mission concepts that include a mothercraft and a swarm of small satellites that can be deployed. ESA's Science Directorate requested and managed the study as one of three topics selected for investigation following the "New Science Ideas" call for proposals.
The concept studied was a proposal to perform multi-point (and possibly multi-target) measurements around small bodies (asteroids and comets), as well as Mars or Venus, to gather information from different locations simultaneously.
The main goal of the study was not to design a specific mission but to provide a "tool-box" of technical building blocks the community can use to develop these new planetary mission architectures, in reply to future science calls.
The full CDF study report consists of three main reports, each available in pdf format below:

We present a 3D orbit viewer application capable of displaying science data. 3DView, a web tool designed by the French Plasma Physics Data Center (CDPP) for the planetology and heliophysics community, has extended functionalities to render space physics data (observations and models alike) in their original 3D context. Time series, vectors, dynamic spectra, celestial body maps, magnetic field or flow lines, 2D cuts in simulation cubes, etc, are among the variety of data representation enabled by 3DView. The direct connection to several large databases, the use of VO standards and the possibility to upload user data makes 3DView a versatile tool able to cover a wide range of space physics contexts. The code is open source and the software is regularly used at Masters Degree level or summer school for pedagogical purposes. The present paper describes the general architecture and all major functionalities, and offers several science cases (simulation rendering, mission preparation, etc.) which can be easily replayed by the interested readers. Future developments are finally outlined.
CHEOPS is a space science mission dedicated to the study of known exoplanets orbiting bright, nearby stars. It will use the technique of ultra-high precision photometry to measure accurate sizes of a large sample of Earth to Neptune-sized planets. By combining the accurate sizes determined by CHEOPS with existing mass measurements, it will be possible to establish the bulk density and composition of the planets; these, together with information on the host stars and the planets' orbits will be used to determine the planets' formation and evolutionary history.
CHEOPS is a small satellite with a total launch mass of approximately 300 kg and dimensions of 1.55m (height) × 1.49m (width, measured from solar array edge to edge) × 1.4m (depth).
The dark colours used in this paper model are representative of the true colours of the various spacecraft components. The paper model's scale is 1:15 when printed on DIN A4 paper.
CHEOPS is a partnership between the European Space Agency (ESA) and Switzerland.
