avionics;• Ground power outages from
currents induced in lines;• Disruption to communications
relying on the ionosphere;• Disruption of navigation satellite
signals (GPS - Galileo);• Prospecting;• Climate;
Definition: "conditions on the sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-borne and ground-based technological systems and can endanger human life or health."

Space Weather Interests within ESA
• ESA is interested in space weather as both a provider and user of space weather data
• Pre-mission space environment analysis and recommendations for operational procedures carried out at ESTEC (D/TEC)
• Operational use of space weather data and services in support of ESA missions at ESOC & ESAC (D/Ops) with ESTEC support
• New data generated by ESA missions, either as primary goal or in the form of radiation monitor data

ESWW4, 5-9th November 2007
SWENET Perspective• ESA/GSP support for service development concluded 2006• Majority of SDA services have identified funding for service
continuation to 2008 + ..• SWENET Portal maintenance and validation phase continuing
– Inclusion of new SDAs – Validation of new data and services: demonstration of added value– Improvement of data analysis via portal capabilities – Consultation with SDA community on future requirements
• Usage statistics (Based on Jan – Jul 2007): – 4000 visitors/month– 50,000 pages served (not including search engines)
• SDA community continue to meet and collaborate. Next SWENET meeting Splinter 1 this afternoon
• Coordination with national activities and other groups e.g. ISES, COST 724, COST 296, NOAA/SEC (now SWPC), ILWS End Users Task Group…
ESWW4, 5-9th November 2007
Benefit Data By Industry
• Growth indicated by industry– note airlines included in ionospheric &
consequently strong increase in benefit when automated landing taken up
ESWW4, 5-9th November 2007
Net Benefit Trends
LoS1: relies on continued GB Networks and provides mainlyNowcasts.
LoS3: Has low external Dependencies, is more costly, Provides forecasts and Ultimately larger benefits.
LoS2: Potentially high benefitsBut also high risks. Permanent hitch-hiker solutionc.f. GOES/SEM Arrangement could reduce risks
ESWW4, 5-9th November 2007
Strategic Issues• impacts of SW on Europe’s strategic space assets
(Galileo, GMES, telecoms EO..)• impacts of SW on European space infrastructure
(launch, environment monitoring (including situational awareness), manned spaceflight)
• impacts on social infrastructure and economy (energy supply and distribution, emergency relief systems)
• Security issues (HF comms and radar)• ….
These benefits difficult to quantify but report notes space weather services have both potential economic and strategic benefit for Europe
ESWW4, 5-9th November 2007
Space Situational Awareness
ESWW4, 5-9th November 2007
Framework/Context
Space Situation Awareness is a concept that has grown out of the increasing dependence of the modern world on space systems – telecom, navigation, surveillance, etc.
Concept originates with US military – but civilian systems (particularly in Europe) are just as susceptible – Europe needs to develop both policy and capacity.
ESWW4, 5-9th November 2007
Motivation for action on Space Weather • Recent initiatives have revealed both space weather needs and skills
bases in Europe• Development of a more coordinated European approach could be used
to strengthen international cooperation & exchange on basis of partnership.
• At the same time there is a perceived need to build a European framework in the context of Space Situational Awareness.
• Space weather is seen as one of three axes for Space Situational Awareness : – Survey, Tracking, – Imaging – Space weather (space environment monitoring)
At present it is proposed to introduce at the next ESA Ministerial Council an ESA Optional Programme for Space Situational Awareness which may include an element of space weather
ESWW4, 5-9th November 2007
Possible Content• Develop an ESA-led space weather initiative, including
the establishment of a European Centre for Space Weather Services as part of an optional Space Situational Awareness programme
• The initiative would aim to: – Provide a focal point for coordinating ongoing European activities
of the kind initiated in the framework of the Space Weather Applications Pilot Project and SWENET
– Provide a stable nucleus for the development, testing and deployment of future space weather services in Europe
• Proposal in preparation• Ongoing community consultation process
– See splinter meeting on Wednesday afternoon 14:00
ESWW4, 5-9th November 2007
Space Environments and Effects Network of Technical
Competences (SEENoTC)
ESWW4, 5-9th November 2007
• Goals: – to reinforce the coordination of existing and planned space
environments and effects related activities in Europe, – implementation of a coherent European programme of
activities in the domain, • Domain:
– energetic particle radiation and its effects on systems, payloads and humans;
– natural and induced plasma environments and their interactions with spacecraft, and resulting effects on systems and payloads
– Explicitly excluded are space debris, micrometeoroid and thermal environments.
– Explicitly included are space weather effects on spacecraft
Overview of SEENoTC Responsibilities
ESWW4, 5-9th November 2007
Organisation
• Working Group– National representatives responsible for collecting inputs from
communities– Responsible for drawing up roadmaps and identifying areas for
coordination and financial support– SWWT Chairman is a member of the WG, responsible for
making recommendations from this community
• Steering Board– National representatives from agencies and funding bodies– Approve roadmaps annually
• Supports activities that build on the main coordination goals of the network
ESWW4, 5-9th November 2007
• Space weather interests a broad cross section of ESA from missions geared to furthering our understanding of underlying phenomena through to protecting ESA spacecraft from its effects
• The SWENET network provides an operational network of user-oriented space weather services– Clear evidence of interest from industry– Input on future requirements solicited from SDA community– Cost and benefit analysis indicates significant potential growth in the
market for space weather services in several areas– Strong community support for maintaining SWENET demonstrated at
ESWWs
• Work in progress in the area of Space Situational Awareness• Scope for coordination of activities geared towards space weather effects
on spacecraft via the SEENoTC
• National activities developing: e.g. in France, Germany, Belgium, Spain…
Summary
ESWW4, 5-9th November 2007
Next Steps
• Short Term: – Next meeting of SWENET community: Splinter 1 this afternoon– Next consultation meeting on SSA: Splinter 3 Wednesday
• Longer Term: – Work will continue on an SSA proposal into 2008– ESA to further investigate how to build on successful outcome of
the space weather applications pilot project– In parallel, ESA’s normal R and D programmes will continue to
support space environment related applications activities. – Continue and expand policy of flying radiation monitors on ESA s/c,
ensuring processing and full exploitation of these data
– Continued collaboration with other national and international space weather initiatives
