The third Copernicus Sentinel-1 satellite tv for pc television for computer was launched on a Vega-C rocket from Europe’s Spaceport in French Guiana. Sentinel-1C extends the legacy of its predecessors, delivering high-resolution radar imagery to observe Earth’s altering environment, supporting a numerous fluctuate of functions and advancing scientific evaluation. Furthermore, Sentinel-1C introduces new capabilities for detecting and monitoring maritime guests.
Sentinel-1C was launched into orbit on 5 December, lifting off aboard Vega-C at 22:20 CET (18:20 native time). The launch proceeded simply, with the rocket reaching home in eight minutes and dropping off Sentinel-1C at roughly 00:04 CET.
The launcher’s mission, generally known as VV25, is a return-to-flight for Vega-C – Europe’s lightweight, high-performance rocket – marking the restart of routine industrial operations for the model new launcher. At 00:12 CET, ESA established communication with the satellite tv for pc television for computer confirming that it was safely in orbit.
ESA’s Director Primary Josef Aschbacher talked about, “One second combined two good European achievements proper now: the third launch of a Sentinel-1 satellite tv for pc television for computer and the third launch of Vega-C, marking a triumphant return to type for every flagship European initiatives. It was thrilling and touching to see the combo of the European launcher and Copernicus group and teams rooting each other on in true Workers Europe type.
“With the insertion of Sentinel-1C into orbit, ESA continues a legacy of steadfast Sentinels defending the Earth and exemplifies why Europe needs secured flights: on account of what we ship to deal with provides benefits to Earth, and all of it begins with a launch.”
ESA’s Director of Home Transportation Toni Tolker-Nielsen talked about, “Within the current day’s launch marks an important step forward, reaffirming European unbiased entry to deal with. With Vega-C once more in flight and the inaugural launch of Ariane 6 in July, we’re in a superb place going forward and I salute the entire hard-working teams all through Europe and its spaceport who’ve labored tirelessly to comprehend this success.”
ESA’s Director of Earth Comment Programmes Simonetta Cheli added, “We’re thrilled to rejoice the launch of Sentinel-1C, an occasion of the enduring partnership between ESA and the European Payment. The mission performs an important place in addressing worldwide challenges like native climate change and disaster response, whereas guaranteeing the continuity of necessary radar information for monitoring Earth’s land, oceans and ice.
“With Sentinel-1C effectively in orbit and Vega-C once more in flight, Europe continues to exhibit its administration in home, delivering tangible benefits for Earth by cutting-edge experience and collaboration.”

About Copernicus Sentinel-1C
Sentinel-1A was the first satellite tv for pc television for computer inside the sequence, launched in April 2014, adopted by the launch of Sentinel-1B in 2016. The Sentinel-1B mission bought right here to an end in August 2022 after experiencing a technical fault that rendered it unable to amass information. The satellite tv for pc television for computer has been effectively de-orbited and may reenter Earth’s ambiance inside 25 years.
Sentinel-1C, along with its sibling Sentinel-1A, will return the mission to its full potential as a two-satellite constellation. Sentinel-1A is then resulting from get changed by Sentinel-1D later subsequent 12 months.
Carrying superior radar experience to supply an all-weather, day-and-night present of pictures of Earth’s flooring, the formidable Copernicus Sentinel-1 mission has raised the bar for spaceborne radar. Sentinel-1 carries a C-band synthetic aperture radar (SAR) instrument, which allows it to grab high-resolution imagery of Earth’s flooring.
Sentinel-1 information contributes to fairly a number of Copernicus corporations and functions, along with Arctic sea-ice monitoring, iceberg monitoring, routine sea-ice mapping and glacier-velocity measurements. It moreover performs a big place in marine surveillance, resembling oil-spill detection, ship monitoring for maritime security and monitoring illegal fishing actions.
Furthermore, it is extensively used for observing flooring deformation introduced on by subsidence, earthquakes and volcanic train, along with for mapping forests, water and soil sources. The mission is important in supporting humanitarian help and responding to crises worldwide.
Sentinel-1C and Sentinel-1D introduce new capabilities for detecting and monitoring maritime guests, by their built-in Computerized Identification System (AIS). This system contains 4 onboard antennas and optimises the seize of indicators transmitted by ships, which embody important particulars resembling a vessel identification, location and course of passage, enabling actual monitoring.
Sentinel-1 information are freely accessible via the Copernicus Info Home Ecosystemproviding immediate entry to a wide range of information from every the Copernicus Sentinel missions and the Copernicus Contributing Missions.
The Sentinel-1 mission is the outcomes of shut collaboration between ESA, the European Payment, enterprise, service suppliers and information clients. Designed and constructed by a consortium of larger than 70 corporations led by Thales Alenia Home and Airbus Defence and Home, it is a superb occasion of Europe’s technological excellence.
About Vega-C
Europe’s Vega-C rocket can launch 2300 kg into home, resembling small scientific and Earth assertion spacecraft. At 35 m tall, Vega-C weighs 210 tonnes on the launch pad and reaches orbit with three solid-propellant-powered ranges sooner than the fourth liquid-propellant stage takes over for actual placement of satellites into their desired orbit spherical Earth. Vega-C is the evolution of the Vega family of rockets and delivers elevated effectivity, increased payload amount and improved competitiveness.
Complementing the Ariane family to launch all types of payloads into their desired orbits, Vega-C ensures that Europe has versatile and unbiased entry to deal with. ESA owns the Vega-C programme, working with Married as prime contractor and design authority. Arianespace was the launch service provider for Sentinel-1C.
This launch marks Vega-C’s return to flight, a key step in restoring Europe’s unbiased entry to deal with. The first industrial flight in December 2022 failed due to a nozzle topic in its Zefiro-40 motor.
Since then, an improved nozzle was designed and constructed and all the Zefiro-40 stage has undergone two worthwhile firing exams, in Would possibly and October 2024, which demonstrated the motor’s means to hold out reliably under completely completely different stress circumstances and burn interval. These exams confirmed the motor’s readiness, and clear the path for Vega-C’s flight with Sentinel-1C.
