SpaceX celebrated the first human spaceflight from its Cape Canaveral launch site on Saturday, and while the two humans aboard the Crew Dragon Freedom are safely on their way to the International Space Station,

The Crew-9 incident was the second Falcon 9 upper-stage issue to crop up in less than three months. On July 11, the rocket experienced a leak of liquid oxygen in its upper stage during the launch of 20 of SpaceX's Starlink internet satellites. As a result, the spacecraft were deployed too low and ended up being lost.

SpaceX's two-person Crew-9 mission arrived at the International Space Station today (Sept. 29) after a one-day orbital chase.

Space Launch Complex 40 is located just south of Kennedy Space Center. Once the Crew-9 duo launched, the Falcon 9 rocket traveled on a northeast trajectory, carrying their SpaceX Dragon, named Freedom, on a path to meet up with the International Space Station.

SpaceX has put a pause on Falcon 9 launches after reporting the second stage of the rocket used in Crew-9 experienced an off-nominal deorbit burn and landed in the ocean outside of its target area.

In a significant milestone for space travel, the SpaceX crew tasked with bringing back two astronauts stranded on the International Space Station (ISS) successfully docked with the orbiting laboratory on Sunday,

In that incident, the FAA grounded Falcon 9 for two weeks when the video feed of a launch from California on July 11 showed the second stage’s engine freezing over in space. It resulted in SpaceX not being able to put its payloads into a correct orbit.
