Experience the preparation of the MetOp-SG-A1 satellite, hosting Copernicus Sentinel-5, scheduled for liftoff on an Ariane 6 rocket from Europe’s Spaceport in Kourou, French Guiana, on 13 August 2025 at 02:37 CEST (12 August 21:37 Kourou time). This timelapse video captures key stages from the encapsulation within the Ariane 6 fairing to the installation in the launch tower.

MetOp-SG-A1 is the first in a series of three successive pairs of satellites. The mission as a whole not only ensures the continued delivery of global observations from polar orbit for weather forecasting and climate analysis for more than 20 years, but also offers enhanced accuracy and resolution compared to the original MetOp mission – along with new measurement capabilities to expand its scientific reach.

This new weather satellite also carries the Copernicus Sentinel-5 mission to deliver daily global data on air pollutants and atmospheric trace gases as well as aerosols and ultraviolet radiation.

New research suggests the first stars weren't the behemoths we expected them to be — which might explain why we haven't seen them yet.
