SpaceX has successfully launched the Sentinel-6B satellite aboard its reliable Falcon 9 rocket from the Vandenberg Space Force Base (VSFB) in California. This mission is designed to precisely monitor global sea-level changes and oceanic conditions. The scientific value of this satellite is significant, as it will collect crucial data related to climate change, ocean temperature, currents, and rising sea levels.

Sentinel-6B

¨     The satellite carries six scientific instruments that will measure sea level rise and monitor related ocean conditions.

¨     Sentinel-6B (also known as Jason-CS B) will orbit Earth at a speed of 7.2 kilometers per second and complete one orbit in approximately 112 minutes.

¨     The data obtained from the satellite will aid in forecasting fair weather and storms and help plan coastal infrastructure accordingly.

¨     Sentinel-6B is an Earth-observation satellite jointly developed by NASA, ESA (European Space Agency), U-MetSat (European Organisation for the Exploitation of Meteorological Satellites), and the National Oceanic and Atmospheric Administration (NOAA).

¨     Sentinel-6B will work in conjunction with its twin satellite, Sentinel-6 Michael Freilich, which has been in orbit since November 2020

Purpose of the Sentinel-6B Mission

¨     The Sentinel-6B satellite is part of a collaborative effort between the European Union (EU), NASA, NOAA, and EUMETSAT. It follows the Sentinel-6A satellite launched in 2020. Together, both satellites will provide highly accurate sea-level measurements for the next decade.

Key objectives

¨     Accurate monitoring of sea-level rise:The satellite can measure sea-surface height with extremely high precision.

¨     Better understanding of global climate change:It will help study rising temperatures, melting polar ice, and oceanic heat content.

¨     Improved marine weather and storm forecasting:Meteorologists will be able to make more reliable predictions using high-quality ocean data.

¨     Analysis of ocean currents and waves:This information will support navigation, maritime transport, and the fishing industry.

Falcon 9: The Reliable Rocket Behind the Mission

¨     Falcon 9 is the world’s first reusable orbital-class rocket. In this mission too, the first-stage booster made a controlled landing on a drone ship at sea, allowing it to be refurbished and reused. This reusability makes space missions more cost-effective, faster, and environmentally sustainable.

Global Importance of the Data

The data collected by Sentinel-6B will be crucial for

¨     Climate scientists

¨     Ocean researchers

¨     Meteorological departments

¨     Environmental agencies

¨     Coastal city planners
