Sentinel-3B Launch Replay – measuring weather and oceans

Sentinel-3B Launch Live

Sentinel-3B Launch REPLAY – Sentinel-3B joins its twin, Sentinel-3A, in orbit. We invite you to watch again. This one of the most important satellites in orbit. Blast off Wednesday 25 April from 18:30 BST. It was a perfect launch in excellent weather conditions

This was the launch programme:

The live web stream began at 18:30 BST (19:30 CEST) and end at 19:40 GMT (21:40 CEST), and was divided in two parts:

18:30-20:15 CEST/BST      Last preparations at Plesetsk, liftoff, and updates from ESA’s mission control in Darmstadt, Germany

20:15-21:10 CEST/BST      Break

21:10-21:40 CEST/BST      Updates from mission control in Darmstadt on separation and acquisition of signal

The pairing of identical satellites provides the best coverage and data delivery for Europe’s Copernicus programme.  It is the largest environmental monitoring programme in the world. The satellites carry the same suite of cutting-edge instruments to measure oceans, land, ice and atmosphere.

The Sentinel-3B was launched into orbit on a Rockot launcher from the Plesetsk Cosmodrome in northern Russia.

What it does

This multi-faceted mission will measure Earth’s oceans, land, ice and atmosphere. Also monitor and understand large-scale global dynamics. It provides essential information in near-real time for ocean and weather forecasting. This is part of Europe’s Copernicus Programme. Leading the launch is the European Space Agency.  ESA brought together some of the world’s scientists and engineers to develop and build the satellite.

Engineers began preparations mid March in Plesetsk.  The multi instruments mission ready for its journey into orbit.

Scientists from Plymouth developed a special surfboard to track the ocean. The surfboard was fitted with a specially designed fin that transmits data back to earth.  The trial was for the Sentinel-3B satellite.

Watch the swirl of smoke as the satellite breaks away from the launching pad.  Weather forecast is good.  It was not a windy day.  Too much wind could affect a steady launch. A lot of noise but it happens with every blast off. An exciting launch. Essential for science. Scientists excited about the kind of data they will receive.

Watch the replay – it is a key launch.  Did you catch the blast-off?  Let us know what you think of the project. We want to hear from you.  Leave your thoughts in our comment box below
