Sentinel-3B a tight fit in the fairing half shell

There is only clearance of less than 5 cm between the satellite and the inside of the fairing shells.

The Copernicus Sentinel-3B satellite will be carried into orbit on a Rockot launcher.

Once safely in orbit and fully commissioned, this new satellite will begin its mission to map Earth’s oceans and land surfaces with its powerful optical and radar systems. The Sentinel-3 mission is set to play a key role in the world’s largest environmental monitoring programme – Copernicus.
