"Russia is planning to launch a rescue vessel to the International Space Station next month. They hope to bring home three crew members who are stuck in orbit because their original capsule was hit by a meteoroid.
The stuck vessel is Soyuz MS-22, it has a major leak that is spraying radiator coolant into space and it kept two cosmonauts from doing a planned spacewalk.
Micrometeoroids are a significant danger to human spaceflight. They hurl around the Earth at about 17,000mph, which is much faster than the speed of a bullet. The diameter of the micrometeoroid that hit the docked Soyuz was tiny, creating a hole in the capsule that was just 1mm in diameter. But even that small of a hole caused significant damage. Some of the images of the craft show white particles resembling snowflakes streaming out of the rear."
