Sentinel-6B Launched to Monitor Rising Sea Levels from Space

• Sentinel-6B was launched on 17 November aboard a SpaceX Falcon 9 rocket. Lift-off took place from the Vandenberg Space Force Base, California.
• The mission is a joint effort of:
  • NASA
  • NOAA (National Oceanic and Atmospheric Administration)
  • European Space Agency (ESA)

Mission Purpose: Tracking Global Sea-Level Rise

• Sentinel-6B continues a series of sea-level monitoring satellites dating back to the 1990s.
• It will provide highly accurate measurements of:
  • Sea-surface height
  • Ocean temperature
  • Ocean circulation patterns
• The satellite carries six science instruments dedicated to ocean monitoring.

Importance of the Data

• Ocean data is crucial for:
  • Weather forecasting
  • Storm and flood prediction
  • Tracking climate-driven sea-level rise
  • Protecting undersea pipelines and communication cables
  • Maritime navigation and shipping services
• Sentinel-6B is expected to enhance the precision of weather and climate models, helping authorities take timely action to protect coastal communities and infrastructure.

Technical Features and Orbit

• Sentinel-6B carries advanced radar altimetry technology, identical to its predecessor Sentinel-6 Michael Freilich.
• The technology extends the sea-surface height record maintained since the early 1990s.
• Orbit characteristics:
  • Speed: 7.2 km per second
  • Completes one Earth orbit in 112 minutes

Extending a Legacy of Sea-Level Monitoring

• With Sentinel-6B, the international community strengthens a three-decade-long record of ocean height measurements.
• The mission will support crucial scientific understanding of climate change, ocean expansion, and coastal risk assessment.
