Europa Narrow Slice of Surface

The First Akon Europa Penetrator Workshop

For general information on the Akon Europa Penetrator, click here.

Many thanks to those who participated in the successful First Akon Workshop at the Royal Astronomical Society, London, on January 21, 2016.

Activities to further develop the Akon Penetrator concept are continuing. We welcome contributions from all interested scientists and engineers. If you interested in joining the Akon Team, please email Geraint Jones, at g(dot)h(dot)jones@ucl.ac.uk.

The information below concerning the meeting that was held on January 21 2016 is being left online for information.

Background

Jupiter's moon Europa is one of the most intriguing objects in our Solar System. This 2000km-wide body has a geologically young solid water ice crust that is believed to cover a global ocean of liquid water. The presence of this ocean, together with a source of heating through tidal forces, make Europa a conceivable location for extraterrestrial life. The science case for exploring all aspects of this icy world is compelling.

NASA has selected the Europa Mission (formerly Europa Clipper) to study Europa in detail in the 2020s through multiple flybys, and ESA's JUICE mission will perform two flybys of the body in the 2030s. The US agency has extended to the European Space Agency an invitation to provide a contribution to their mission. European scientists interested in Europa science and exploration are currently organizing themselves, in the framework of a coordinated Europa M5 Inititative to study concurrently the main options for this ESA contribution, from a simple addition of individual instruments to the NASA spacecraft, to a lander to investigate Europa's surface in situ.

A high speed lander - a penetrator -  is by far the most promising technology to achieve this latter option within the anticipated mass constraints, and studies of such a hard lander, many funded by ESA, are now at an advanced level. The penetrator would impact Europa's surface at several hundred metres per second, and travel up to several metres into the moon's subsurface.

ESA is expected to issue its fifth call for medium (M) class missions in 2016. Possible contributions to the NASA Europa Mission are to be submitted to ESA in response to this M5 call.

An international team to formally propose an Europa penetrator to ESA is growing. The working title of this proposal is Akon (Άκων), named after the highly accurate javelin gifted to Europa by Zeus in ancient Greek mythology.

Meeting Aims

This workshop is being convened to bring together all those interested in contributing to the Akon penetrator, both through scientific involvement and potentially as instrument providers, in preparation for an M5 proposal to ESA. The topics to be covered at the meeting are:

  • Current status of penetrator studies, future plans, and possible mission scenarios.
  • The science goals to be addressed by the Akon Europa Penetrator and its delivery vehicle, especially those that complement the planned observations of ESA's JUICE mission and NASA's Europa Mission.
  • Potential instrument contributions. Instrument concepts are to be considered to address a wide range of scientific topics, from Europa's tenuous atmosphere, surface and near-surface composition, through geophysics and geomorphology, to habitability and astrobiology.

There will be time allocated for open discussion of these three themes.

By the conclusion of the meeting, we hope to have outlined the primary mission goals, identified an initial list of potential instruments and their providers, with a very broad ranking that takes into account potential scientific return, mass and power budgets, and technology readiness levels that are achievable within a reasonable timescale.

The outcomes of this workshop and subsequent activities over the following 5 weeks will be presented to a subsequent Europa Initiative Workshop, to be held in Madrid, Spain, on February 29-March 1, where all potential European contributions to the NASA Europa Mission will be concurrently discussed.
