Explainer: What we know about North Korea's new satellite and claims of Russian aid

Officials and experts are trying to independently verify North Korea's claim that it successfully launched its first spy satellite. South Korea believes that the launch likely involved Russian aid. While it is unclear if the satellite is operating in orbit or if North Korea received outside help, analysts believe that the satellite is likely a small, low-resolution optical satellite. It could be useful for identifying large troop movements but is unlikely to provide detailed intelligence on specific weapons systems.
