US, Europe and SpaceX launch a satellite to track rising global sea levels

Sentinel-6 Michael Freilich will have a companion in the future. A twin satellite, Sentinel-6B, will launch in 2025. The combo should help maintain the climate record for “at least” another decade between the two vessels, NASA said. It’ll take about a year for the initial satellite to take over from its predecessor, Jason-3.

The timing might be ideal. The incoming US administration is expected to fully recognize climate science, and an advanced satellite could help the administration make better-informed policy decisions.
