Sentinel-3C sends first ocean-colour images and Greenland ice heights two weeks after launch

Copernicus's Sentinel-3C satellite returned its first images and measurements from two of its key instruments two weeks after launch. It is the third satellite in the series and carries the same instruments as the others, so users of its sea, ice and land data have early evidence the record will continue once commissioning ends.

Nuri spaces five NEONSAT satellites seconds apart to start Korea's first home-launched constellation

Korea's Nuri rocket placed 15 satellites at about 575 km on its fifth flight, five of them the first home-launched NEONSAT Earth-observation microsatellites. The other half of the 10-satellite constellation, and the coverage it was designed for, waits on a sixth flight next year.

Sentinel-6B's sea level data waits five months for NOAA's hurricane heat algorithm

The new altimeter has been sending low-latency measurements since July 15, but NOAA's operational ocean heat suite is only targeted to start using its ocean height data by the end of the year, so this El Nino is being forecast on the record that already existed.
