SpaceX was unsuccessful in its attempt to land its Falcon 9 rocket on a drone ship in the Pacific ocean on Sunday January 17.
The rocket did successfully launch the Jason 3 satellite, but on its return trip to Earth it came in harder than expected and one of its landing legs broke.
This is the third time SpaceX has failed to stick the rocket landing at sea.
First stage on target at droneship but looks like hard landing; broke landing leg. Primary mission remains nominal → https://t.co/tdni53IviI

Unfortunately the live feed of the landing cut out.
Live satellite video from ship at sea is technically difficult. Loss of video signal could have been caused by booster’s own noise. #Falcon9

But SpaceX said it will release footage of the landing attempt soon.
The launch of the satellite into orbit however, which was the primary objective of the mission, was successful.
Second stage re-ignition successful. Jason-3 satellite has been deployed.

In December last year, the company successfully pulled off a land-based landing, but landing a rocket at sea is much more difficult. The target is smaller and isn’t completely still as it’s tossed about in the waves.
On Monday, Musk tweeted that these kind of drone ship landings are "needed for high velocity missions."
High-velocity missions are mainly commercial launches, when the Falcon 9 has to carry a payload higher than it would on a cargo mission to the International Space Station (ISS). This Jason 3 satellite launch is a high-velocity mission, so that's why SpaceX had to attempt to land the rocket at sea.
