NASA officials gave approval Tuesday for SpaceX to begin regular crew rotation flights to the International Space Station with the launch of four astronauts set for Saturday from the Kennedy Space Center in Florida, signaling a transition from development to operations for the human-rated Dragon spacecraft.

NASA Astronaut Shannon Lucid spent six months aboard the Mir Space Station in 1996. In this video she gives a guided tour of the Russian space outpost.

A NASA official said Friday that SpaceX’s Crew Dragon spacecraft could be ready to ferry astronauts Doug Hurley and Bob Behnken to the International Space Station as soon as early March, pending the results from a major demonstration of the ship’s launch abort system this weekend, a pair of parachute drop tests, and space station crew schedules.
