SpaceX has paused launches of its workhorse Falcon 9 rocket after it suffered an anomaly during a key NASA mission. The launch vehicle’s first stage experienced an “off-nominal deorbit burn” right after it sent the Dragon spacecraft toward the International Space Station (ISS) on September 28, prompting SpaceX to launch an investigation. A deorbit burn is a manoeuvre wherein the engine is fired to lower the rocket’s altitude in space.
The Dragon spacecraft was carrying NASA astronaut and Roscosmos Cosmonaut Aleksandr Gorbunov who launched for the Crew-9 mission. Thankfully, the astronauts have safely arrived at the orbiting laboratory.
In a statement, SpaceX said that the second stage, as a result of the anomaly, fell into the ocean as intended but not in the targeted area.
After today’s successful launch of Crew-9, Falcon 9’s second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn. As a result, the second stage safely landed in the ocean, but outside of the targeted area.
We will resume launching after we…

“After today’s successful launch of Crew-9, Falcon 9’s second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn. As a result, the second stage safely landed in the ocean, but outside of the targeted area,” SpaceX said. “We will resume launching after we better understand root cause,” it added.

The Crew-9 mission is NASA’s ninth crew rotation mission launched by SpaceX. The two astronauts will spend six months aboard the station and return with Sunita Williams and Barry Wilmore who were supposed to be back in eight days after their launch on June 5.
But Boeing’s faulty Starliner extended their stay to February 2025.
This is the second time this year when the second stage malfunctioned. Earlier in July, the one and only engine of the second stage carrying 20 Starlink satellites exploded while on its way to the planned orbit. Consequently, it failed to reach the intended orbit and the satellites fell back to Earth in a few days.
