"North Korea said Tuesday it had conducted the final ground test of a solid-fuel rocket engine for a long-range ballistic missile in its latest advancement toward having an arsenal that could viably threaten the continental United States, the Associated Press reports. The test Monday observed by leader Kim Jong Un was the ninth of the solid rocket motor built with carbon fiber and capable of producing 1,971 kilonewtons (443,000 pounds) of thrust, more powerful than past models, according to the North's official Korean Central News"

Four astronauts are less than six months away from traveling around the far side of the Moon and leaving low-Earth orbit for the first time in more than 53 years. Concerns exist about the high cost of the Space Launch System rocket, the complexity of new commercial lunar landers, and a bleak budget outlook for the Artemis program. North Korea conducted the final ground test of a carbon-fiber solid-fuel rocket motor for a long-range ballistic missile capable of producing 1,971 kilonewtons (443,000 pounds) of thrust. The test observed by leader Kim Jong Un was the ninth such test. Solid-fueled ICBMs offer greater mobility, longer storage life, and easier concealment, transport, and launch compared with liquid-fueled missiles.
