“…A number of nations have begun a coordinated approach to addressing these risks and forecasting the environment, for example in the USA [12], the UK [13], Japan [14] and Mexico [15]. In 2011, the UK entered space weather behaviour into their National Risk Register and placed it as the fourth highest risk [16].…”

The world has become very reliant on satellites. Businesses, Governments and Critical National Infrastructure (CNI) are using space systems at an unprecedented scale. For example, timing signals from GNSS synchronise high speed financial transactions and energy networks, while communications networks rely on satellites for connectivity, broadcast infrastructure and backhauling. However, the dependence of our society on space systems means we are vulnerable to any threats to space infrastructure. Whilst governance is one of the keys to effective space security, protection and planning also play critical roles. This work focusses on planning, by modelling threats to space systems.The aim of this work was to contribute the satellite element to an application or 'app' being developed for military and civilian infrastructure managers and business leaders. The app will allow the evaluation of risk to spacecraft and to all the downstream elements of infrastructure and business processes that they service. This app is a software model called 'SpaceAware Resilience'. Previously it modelled only the downstream impact of degraded services from satellites but did not model the risk to the satellite systems themselves. The objective of this work was to add this element to the model. This included evaluating a variety of threats to satellite systems and establishing some possible threat scenarios for later demonstration purposes. This work was limited to threats to the orbiting satellite itself, as the least understood part of the infrastructure, not to the ground stations or up-or downlinks. Two types of threats were established: unintentional and intentional. Unintentional threats included space debris and space weather radiation effects on satellites and their services, intentional threats included anti-satellite weapons and cyberattacks. Risk scenarios were selected based on incidents with historical data available. This information will help the next stage of modelling likelihood and impact. It is hoped that this improved threat model will help agencies, companies and government learn more about the key vulnerabilities of space systems, the infrastructure they serve and possible mitigations.

“…Likewise, Bhardwaj et al () traced the history of Indian observations related to the space environment from the mid‐1850 to present. In an update to Kamide (), Ishii () discusses the existing and planned core elements of Japanese space weather prediction system and the innovative Project for Solar‐Terrestrial Environment Prediction. Additionally, Lockwood () supplied commentary and insight into James Dungey's early views of reconnection and the magnetospheric convection cycle.…”

“…Recognizing the potential damage to military operations that interruptions to radio communications and navigation aids could have, the British government established the Inter‐Services Ionospheric Bureau to improve radio‐based direction finding and to predict optimum frequencies for radio transmissions. Similar organizations in Australia, Germany, and Japan were established to furnish radio propagation data and prediction services during the war [ Bhattacharya and Lichtman , ; Ishii , ].…”

Public awareness of space weather and its adverse effects on critical infrastructure systems, services, and technologies (e.g., the electric grid, telecommunications, and satellites) has grown through recent media coverage and scientific research. However, federal interest and involvement in space weather dates back to the decades between World War I and World War II when the National Bureau of Standards led efforts to observe, forecast, and provide warnings of space weather events that could interfere with high‐frequency radio transmissions. The efforts to observe and predict space weather continued through the 1960s during the rise of the Cold War and into the present with U.S. government efforts to prepare the nation for space weather events. This paper provides a brief overview of the history of federal involvement in space weather forecasting from World War II, through the Apollo Program, and into the present.
