Change: launch postponed to Thursday 5 December 2024.
Attributable to a mechanical issue stopping the withdrawal of the mobile gantry, the launch chronology has been stopped.
The earliest targeted launch date is deliberate for tomorrow Thursday 5 December 2024 at 22:20 CET (18:20 native time in Kourou). The launcher and its passenger the Copernicus Sentinel-1C satellite tv for pc television for computer are in regular and guarded circumstances.
Tune in to ESA WebTV on 5 December from 22:00 CET to look at the satellite tv for pc television for computer soar into space on a Vega-C rocket to be launched from Europe’s Spaceport in Kourou, French Guiana.
The launch could be the return to flight for Vega-C, Europe’s lightweight, high-performance rocket – extra securing Europe’s autonomy in space after the worthwhile launch of Ariane 6 last summer season.
As quickly as in orbit, Sentinel-1C will delay the Sentinel-1 mission’s legacy, delivering radar imagery to look at Earth’s altering environment to assist a numerous fluctuate of functions and scientific evaluation.

About Copernicus Sentinel-1C
The Sentinel-1 mission, the first throughout the family of Copernicus, is based on a constellation of two equal satellites flying within the similar orbit nonetheless 180° apart, to optimise worldwide safety and data provide for Copernicus – the Earth comment a part of the EU’s Space Programme.
Sentinel-1A was the first satellite tv for pc television for computer throughout the sequence, launched in April 2014, adopted by the launch of Sentinel-1B in 2016. The Sentinel-1B mission acquired right here to an end in August 2022 after experiencing a technical fault that rendered it unable to build up data. The satellite tv for pc television for computer has been effectively de-orbited and may re-enter 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 on account of get changed by Sentinel-1D later subsequent 12 months.
As a sophisticated radar mission, Copernicus Sentinel-1 can image the ground of Earth by the use of cloud and rain and regardless of whether or not or not it is day or night. Sentinel-1 carries a C-band synthetic aperture radar (SAR) instrument, which allows it to grab high-resolution imagery of Earth’s flooring.
This extremely efficient radar system operates in a variety of modes, along with enormous swath and high-resolution, providing detailed data on land subsidence, ice actions and ocean circumstances.
The model new Sentinel-1C satellite tv for pc television for computer can also carry a model new Computerized Identification System (AIS). Developed by the Worldwide Maritime Organisation, this technique is designed to help ships avoid collisions, considerably after they’re too faraway from land-based radar strategies. This know-how assigns a novel ID to each vessel and tracks its place and actions in real-time, making a digital map of the ships at sea.

About Vega-C
Europe’s Vega-C rocket can launch 2300 kg into space, akin to small scientific and Earth comment spacecraft. At 35 m tall, Vega-C weighs 210 tonnes on the launch pad and reaches orbit with three solid-propellant-powered phases 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, higher payload amount and improved competitiveness.
Complementing the Ariane family to launch all sorts of payloads into their desired orbits, Vega-C ensures that Europe has versatile and neutral entry to space. ESA owns the Vega-C programme, working with Married as prime contractor and design authority. Arianespace will operate the launch service provider for the launch of Sentinel-1C.
This launch marks Vega-C’s return to flight, a key step in restoring Europe’s neutral entry to space. The first enterprise flight in December 2022 failed attributable to a nozzle issue in its Zefiro-40 motor. Since then, an improved nozzle was designed and constructed and the entire Zefiro-40 stage has undergone two worthwhile firing checks, in Would possibly and October 2024, which demonstrated the motor’s ability to hold out reliably under completely totally different pressure circumstances and burn durations. These checks have confirmed the motor’s readiness, clearing the path for Vega-C’s upcoming flight.
