Today I've read in the Facebook group of Roscosmos (original text in Russian) that 16 years ago on this day the Zvezda module was launched into space. According to the article 2 weeks later it docked to the ISS, which back then consisted of the Unity and Zarya modules.
AFAIR the Soyuz spacecraft can reach the ISS in 6 to 48 hours.
Why did it take Zvezda 2 weeks to dock to the ISS? Or is this a typo?
