[5][8] This data is important to collect and analyze because it is a critical factor in understanding the changes in Earth's climate brought on by global warming as well as ocean circulation.

[9] The primary users of Jason-3 data are people who are dependent on marine and weather forecasts for public safety, commerce and environmental purposes.

National Oceanic and Atmospheric Administration (NOAA) and European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) are using the data primarily for monitoring wind and waves on the high seas, hurricane intensity, ocean surface currents, El Niño and La Niña forecasts, water levels of lakes and rivers.

Designed by CNES in France, DORIS uses the Doppler effect to found its system, which describes the differences in frequencies of waves between source and object.

[15] Following paperwork filed with US regulatory authorities in 2015,[22] SpaceX confirmed in January 2016 that they would attempt a controlled-descent flight test and vertical landing of the rocket's first stage on their west-coast floating platform Just Read the Instructions,[23] located about 200 mi (320 km) out in the Pacific Ocean.

[26] Approximately nine minutes into the flight, the live video feed from the drone ship went down due to the losing its lock on the uplink satellite.

Elon Musk later reported that the first stage did touch down smoothly on the ship, but a lockout on one of the four landing legs failed to latch, so that the booster fell over and was destroyed.

[27][28][29] Debris from the fire, including several rocket engines attached to the octaweb assembly, arrived back to shore on board the floating landing platform on 18 January 2016.
