Beagle 2 Mission Report and Lessons Learned Released

Download Beagle 2 Mission Report and Lessons Learned, University of Leicester

A six month internal investigation by the Beagle 2 Project Team has led
to the publication of two open reports.

1. The Beagle 2 Mission Report – which describes the Flight operations
and reports on the possible failure modes that may have prevented the
Lander from returning a signal on 25th December 2003

2. “Lessons Learned” – a complete list of lessons learned from the
mission as a guide for future missions.

Dr. Mark Sims, Beagle 2 Mission Manager [University of Leicester] will
outline the key findings from both reports at a Media Briefing to be
held on

Tuesday 24 August 2004

10.30am – 1.00pm inc. lunch

Background Notes

Since 25th December 2003, the combined academic/industry Mission
Operations team from the University of Leicester, EADS-Astrium and
SciSys has been analysing data from Beagle 2 and since February 2004
conducting an internal enquiry into possible reasons for the
non-fulfilment of the mission. The result is the Mission Report, which
is based on all available information. Because no data was received
from Beagle 2 following its successful ejection from Mars Express on
the 19th December 2003 it is not possible to identify an exact failure
mode however the Mission Report highlights a number of possibilities.
Beagle 2 probably failed some where in the time critical and high risk
phase of entry, descent and landing. The Mission Report analyses all
identified potential failure modes and identify a subset that could be
probable causes.

As a result of the non-fulfilment of the mission a number of Lessons
Learned has been compiled and documented as a guide to making any Mars
Lander mission more robust in the future. In addition the document also
addresses a number of points regarding the management and programmatics
of the Beagle 2 programme to clarify and address a number of issues
raised elsewhere.

These reports represent the end of the first mission for Beagle 2. The
team hopes however that the concept of small Mars Landers will not die
with Beagle 2 and that the payload will fly again to conduct the world
class science planned for the mission and that the technology developed
will be used in future missions.

Beagle 2 was the UK’s first mission to another planet. The project is
a partnership between the Open University, the University of Leicester
and EADS Astrium (UK). Other funding partners included the European
Space Agency (ESA), the Office of Science and Technology, the
Department of Trade and Industry, the Particle Physics and Astronomy
Research Council (PPARC), the Wellcome Trust, the National Space Centre
and the Millennium Commission.

The National Space Centre, supported by the Millennium Commission with
National Lottery funding, is the UK’s largest attraction dedicated to
the excitement of space. Co-founded by the University of Leicester and
Leicester City Council; its other funding partners include, the East
Midlands Development Agency and BT.
