The United States has accused Russia of what it described as threatening satellite behaviour in space, according to reports on the latest dispute involving military and surveillance systems.
The allegation concerns a Russian military satellite reportedly manoeuvring close to a US-Finnish radar satellite. The claim is an assertion by the US administration; further technical information and responses from the parties are important to understanding the incident.
Why satellite safety matters
Close approaches between satellites can raise concerns about collision risks, surveillance and the security of space-based infrastructure. Governments increasingly view space systems as critical to communications, navigation, weather forecasting and defence.
