An unusually close pairing
NASA’s 9 September update describes Sentinel-6B flying about 30 seconds behind Sentinel-6 Michael Freilich. The US–European satellites measure sea-surface height, adding observations to a record extending back to the early 1990s.
Looking beneath a weather headline
Changes in ocean height can help researchers interpret ocean conditions relevant to El Niño and hurricane development. The satellite pair provides closely spaced observations that support that work. These measurements are part of the scientific picture, not a stand-alone forecast of where a storm will strike.
Continuity is the story
A long record allows new measurements to be compared with earlier conditions. That continuity is less visually dramatic than a storm photograph, but central to understanding change. NASA’s account concerns research capability; readers needing immediate storm guidance should consult the appropriate meteorological authority.
