Everything is ready at the European space base in Kourou, French Guiana, for the launch of the important satellite Sentinel-1C, on 4 December at 22:20 Italian time.

Important is the satellite, which is part of the European Union's Copernicus programme and will provide valuable information on the health of our planet, but also important is the launch with the Vega C launcher, also European but essentially built by the Italian Avio of Colleferro.

For two years, in fact, Europe had been at a standstill, with no autonomous access to space and forced to rely on SpaceX for the few launches made in the last 24 months; a heavy crisis broken in July, finally, by the first flight of Ariane 6, a medium-large transport vector, and now it is the turn of Vega C to break the deadlock.

Two years ago, after a perfect maiden flight, Vega C had failed its second mission. The war in Ukraine complicated matters, putting out of business companies from that area, invaded by Russia, that were supplying important parts of the carrier rocket.

The European problem is certainly much broader, given that compared to two launches in the USA in 2024, there is talk of at least 100 and in the east, in China, even a high number, and a panorama of launchers that has just been enriched by the Long March 9, which is reusable and can carry a heavy load of 50 to 150 tonnes and reach the Moon. An important launch that of Vega C, therefore, to reaffirm also Europe's capacity and the will to cancel the accumulated disadvantage.

The Sentinel-1C satellite will instead, once in orbit, allow the European Commission's Copernicus project, operated by ESA and which currently has lost one of its two planned satellites, Sentinel-1B, in 2022, to full functionality.

The work of satellites in space

Now, the two satellites 1A and 1C share the same orbit, at an altitude of 693 kilometres, ensuring easy and fast coverage of the earth's terrain with its radar systems, capable, even in clouds, of distinguishing details as small as 5 metres. Sentinel-1C is equipped with a C-band synthetic aperture radar (SAR), which can obtain high-resolution images even in low-light situations. Instruments like this are crucial for monitoring our planet both for emergencies from disasters, landslides, floods, earthquakes, and to help with land management in terms of development.

Another important task is on the seas, reporting infringements of ships in the seas and oceans and combating the polluting practice of oil spills at sea.

Italy's contribution to the realisation of this satellite developed at the Rome headquarters of Thales Alenia Space was important.

The overall Copernicus programme comprises no less than 12 Sentinel satellite systems, which provide valuable information, including on CO2 trends, the main culprit in explaining global warming.
