Европейское космическое агентство договорилось с Arianespace о запуске спутника Sentinel-1
ПАРИЖ, 8 апреля. /ТАСС/. Европейское космическое агентство (ESA) заключило с компанией Arianespace контракт на запуск спутника Copernicus Sentinel-1C. Об этом сообщила в пятницу пресс-служба ESA.
Спутник, как запланировано, "будет запущен ракетой Vega-С с космодрома Куру во Французской Гвиане в первой половине 2023 года", отмечается в сообщении. Ракета выведет 2,3-тонный спутник на орбиту на высоте около 690 км.
Как отмечает пресс-служба, новый космический аппарат "несет современное радиолокационное оборудование, которое обеспечит круглосуточное наблюдение за поверхностью Земли". Спутники этого семейства предоставляют важную информацию об экологической ситуации на Земле, в частности, об изменении уровня моря, таянии ледников и природных катастрофах.

Первый спутник серии - Copernicus Sentinel-1A - был запущен в апреле 2014 года, второй - Copernicus Sentinel-1B - спустя два года. В настоящий момент второй спутник неисправен. "Поэтому необходимо, чтобы новый спутник был выведен на орбиту и начал работу в максимально сжатые сроки", - говорится в сообщении компании.

Still whispers, but it looks like Sentinel-1C, which is currently scheduled to be launched aboard Vega C in 2024, will be launched aboard Falcon 9. It will likely first be announced that it will be launched aboard the Vega C return to flight mission. However, not only will Vega C likely not make the late 2024 deadline but it's also considered unlikely that it will have the performance on the return to flight mission for S1C, as it's at the high end of the vehicle's performance envelope. When the contract was initially signed in 2022, S1C was slated to be launched in the first half of 2023. Image credit: IABG

ARIANESPACE TO LAUNCH EUROPEAN UNION'S COPERNICUS EARTH OBSERVATION SENTINEL-1C SATELLITE ON DECEMBER 3, 2024

Press release 24-11
Evry-Courcouronnes, 10 October 2024

• On December 3, 2024 (Kourou time), Arianespace will launch Sentinel-1C, a Copernicus
satellite for the European Commission within the scope of a contract signed with the European
Space Agency (ESA).

• This mission will provide crucial environmental data for the planet, while also carrying out
Arianespace's commitment of guaranteeing Europe's independent access to space.

• Sentinel-1C is the 6th Sentinel satellite launched by Arianespace

• This VV25 mission will mark the return-to-flight of the Vega C launcher.

Arianespace's next mission is scheduled for Tuesday December 3rd, 2024, at 6:20 p.m. local time (9:20 p.m.
UTC, 10:20 p.m. CEST), from Europe's Spaceport in Kourou, French Guiana, with a Vega C launcher. The
VV25 mission will place its passenger, the Copernicus Sentinel-1C satellite, into Sun-Synchronous Orbit at an
altitude of around 700 km. Spacecraft separation will occur 1 hour and 43 minutes after lift-off.

Sentinel-1C is part of Copernicus, the European Union's Space program Earth observation component. The
world's most advanced Earth observation system, Copernicus provides continuous, free, and reliable Earth
observation data and services to public authorities, companies and citizens around the globe. The program,
managed by the European Commission, is funded by the European Union with a contribution of ESA.

The Sentinel-1 radar imaging mission is composed of a constellation of two polar-orbiting satellites providing
continuous all-weather, day and night imagery for land and maritime monitoring. C-band synthetic aperture
radar (SAR) imaging has the advantage of operating at wavelengths that are not obstructed by clouds or lack
of illumination and therefore can acquire data during day or night under all weather conditions. Sentinel-1
delivers radar imagery for numerous applications. SAR images are the best way of tracking land subsidence
and structural damage: systematic observations and enhanced interferometric capabilities make ground
movement barely noticeable in everyday life detectable and closely monitorable. As well as being a valuable
resource for urban planners, this type of information is essential for monitoring shifts from earthquakes,
landslides and volcanic uplift. Moreover, it helps geohazard monitoring, mining, geology and city planning
through subsidence risk assessment.

Thales Alenia Space is the prime contractor of Sentinel-1C which arrived in French Guiana on October 8th,
2024. During the launch campaign, the satellite will undergo a precise series of pre-launch tests in preparation
for its lift-off, leading to the Launch Readiness Review (LRR) planned on December 2nd, 2024. The successful
completion of the LRR triggers the approval for proceeding to the launch chronology.

Before the upcoming launch of Sentinel-1C, Sentinel-1A, Sentinel-2A, Sentinel-1B, Sentinel-2B and Sentinel-
2C were successfully launched by Arianespace. The VV25 mission once again highlights Arianespace's
commitment to space for a better life on Earth, as well as ensuring Europe's independent access to space.
This VV25 mission will mark the return-to-flight of the Vega C launcher.

The Vega C launcher has been upgraded with more powerful first and second stage Solid Rocket Motors, bigger
AVUM tanks and with a larger fairing that significantly increase payload mass (up to 2,350t in SSO – Sun-
Synchronous Orbit) and double allowable volume. The launcher also better meets the specific needs of small
spacecraft, thanks to its improved SSMS (Small Spacecraft Mission Service) dispenser and to its AVUM+ motor
that will allow seven re-ignitions. Vega C can thus deliver its payloads on three different orbits on the same
mission, instead of the two previously possible with Vega.

ESA is responsible for the Vega C launch system qualification and is the contracting authority for the
development of Vega C, a programme carried out with participation of thirteen ESA Member States. Avio Spa
(Colleferro, Italy) is the prime contractor and design authority of the Vega C launchers, delivering a ready to liftoff
launcher to Arianespace, which will remain its operator up to Vega/Vega C Flight 29 (VV29).
The first generation in the Vega family was launched in 2012 and flew 22 times, with a successful final flight
on September 4th with Sentinel-2C on board.

The VV25 launch at a glance:

➔ 351st launch for the Arianespace launcher family
➔ 10% of the satellites launched by Arianespace are Earth observation satellites
➔ 6th Sentinel satellite launched by Arianespace
➔ 51st mission for the European Space Agency
➔ 3rd Vega C launch

Copernicus Sentinel-1: radar vision for Copernicus
  European Space Agency, ESA
Meet Copernicus Sentinel-1 – this ground-breaking mission delivers continuous, all-weather, day-and-night imaging for land, ice and maritime monitoring.
Equipped with state-of-the-art C-band synthetic aperture radar (SAR), Sentinel-1 captures high-resolution data around the clock, in any weather, making it indispensable for detecting the subtle changes on Earth's surface that remain hidden from the human eye.
Sentinel-1 data serves a multitude of critical applications: from ensuring the safety and efficiency of maritime traffic, tracking sea ice and icebergs, to monitoring structural integrity and natural hazards, such as earthquakes, landslides and volcanic activity.
Its enhanced radar technology provides precises precise information on ground movement, which is critical for urban planning, infrastructure resilience, subsidence risk assessment and geohazard monitoring.
Through consistent, long-term data collection, Sentinel-1 serves as a global asset, essential for environmental and safety monitoring worldwide. The mission is a beacon of innovation, advancing our understanding of our planet's dynamic landscape.
