ESA's good-natured DevILS
by the European Space Agency
BepiColombo will be the first mission to reap the
rewards of this initiative


24 October
2002 The European Space Agency (ESA) has started a
50-million-euro initiative to bring together Europe's leading aerospace
companies for the next four years. The aim of DevILS is to develop
'intelligent', lightweight spacecraft systems that ESA can use on future
missions. Having these 'plug- and-play' systems will allow Europe to
create lighter spacecraft that perform better. The
traditional way to build a spacecraft is to make each one according to
exact specifications. Just like asking a tailor to make you clothes,
however, this can be an extremely expensive business. ESA has asked the
European aerospace industry to find ways of taking a more 'off-the-peg'
approach when building spacecraft. In this way, they will aim to reuse
such systems on many different spacecraft.
ESA has already taken the first steps towards this sort of reusage and
proved that it saves time and money. For example, the recently launched
Integral gamma-ray satellite reused part of XMM-Newton's design. Mars
Express reuses hardware designed for the comet-chasing mission, Rosetta.
The Venus Express mission is likely to use the same hardware design again.
DeVILS is another way to save the taxpayer's money which uses
'intelligent' systems on-board satellites. An intelligent system is a
multipurpose component that performs the same tasks as a number of
previous units. In this way, you reduce the number of components and the
size and mass of individual spacecraft as well, enabling cheaper missions.

| An essential aspect of
the DevILS initiative is that, at this stage, ESA will not tell the
companies involved what to build. After decades of experience, the
European space industries are invited to demonstrate their creativity.
Anton Linssen, Head of ESA's Science Management Support Office, says,
"We have not given them any mission requirements. It's for industry to
tell us what they want to do to make spacecraft lighter and perform
better. We believe that this approach will allow us to harvest the good
ideas for our entire programme, not just have them directed at a
particular spacecraft."
Linssen is confident that the initiative will stimulate the European
aerospace industry to make satellites cheaper and lighter. This would
definitely improve science missions but could well lead to better
applications in telecommunications, global navigation, and Earth
observation also.
To achieve this, DevILS will urge aerospace companies, who usually
compete with each other for business, to work together. "We think that
having a combined proposal means they will propose things they see as
having advantages in the commercial market as well as to us," says
Linssen.
He believes that the first ESA mission to reap the rewards is likely to
be BepiColombo.In the future, DevILS will allow ESA to make better use of
the money at its disposal. Linssen says, "With the money we have, we
want to fly as many missions as possible and deliver maximum value for
money to the scientific community. Lighter intelligent systems reduce
total mission costs so perhaps we can launch more missions. Alternatively,
we can add more experiments to spaceprobes. Either way, we get more
science."
Note to
editors The companies involved in the first phase
of the DevILS initiative are Astrium (France-Germany-Britain), Alcatel
(France), and Alenia Spazio (Italy), as equal partners. Also involved are
Saab Ericsson (Sweden), Dutch Space (The Netherlands), SENER (Spain), and
Contravenes (Switzerland).
