Europe’s next radar Sentinel unfolds

07/08/2020

In two years’ time, the next Copernicus Sentinel-1 satellite will be launched to join its two siblings in orbit around Earth. With engineers busy building Sentinel-1C, they have recently tested the mechanism that opens its 12 m-long radar antenna.

Copernicus Sentinel-1C is the third Sentinel-1 satellite, following Sentinel-1A and Sentinel-1B, which were launched in April 2014 and April 2016, respectively. The three satellites are identical, each carrying an advanced radar instrument to provide an all-weather, day-and-night supply of imagery of Earth’s surface. The mission has been used to monitor the movement of icebergs, ice sheets and glaciers, ground deformation because of subsidence and earthquakes, floods after severe storms, and much more.

Sentinel-1C is set to ensure the continuity of critical radar images that so many Copernicus environmental services and scientists now rely on.

The mission’s technical success is thanks to its radar instrument – which when open spans a whopping 12 meters. Because the radar is folded to fit into the rocket fairing for liftoff, the deployment mechanism must be thoroughly tested to ensure that all will be well once it is in space.

Copernicus Sentinel-1C is the third Sentinel-1 satellite.

The three satellites are identical, each carrying an advanced radar instrument to provide an all-weather, day-and-night supply of imagery of Earth’s surface. When deployed in space, the radar measures a whopping 12 meters. Because the radar is folded to fit into the rocket fairing for liftoff, the deployment mechanism must be thoroughly tested to ensure that all will be well once it is in space. To simulate this operation in as near realistic environment as is possible on Earth, the radar is hung from a structure that helps to mimic weightlessness. The deployment test not only enables the hardware needed for the deployment to be tested, but also allows for the antenna planarity and flatness to be measured when fully deployed. The tests were carried out at Airbus in Germany.

Europe’s next radar satellite tip-top for flight
07/02/2023

ESA / Applications / Observing the Earth / Copernicus / Sentinel-1

Following its arrival at Thales Alenia Space’s cleanroom facilities in the south of France last October, Europe’s next radar satellite, Copernicus Sentinel-1C, has been put through its paces in a series of tests and demonstrated that it is in tip-top condition for flight. Engineers have also carried out the all-important and precise check to ensure that the satellite fits on the adapter that connects it to the rocket that will take it into orbit.

As the ‘C’ in its name suggests, Sentinel-1C is the third satellite of its kind and will continue the essential task of delivering radar images from space for numerous environmental services.

These services are linked, for example, to monitoring and mapping Arctic sea ice, maritime surveillance including oil-spill monitoring and ship detection, monitoring land-surface for motion risks, mapping for forest, water and soil management and mapping to support humanitarian aid and crisis situations.

Carrying advanced radar technology to provide an all-weather, day-and-night supply of images of Earth’s surface and developed by ESA, the Sentinel-1 satellites have raised the bar for spaceborne radar.

In April 2014, Copernicus Sentinel-1A was the first satellite to be launched for the European Union’s Copernicus programme, the Earth observation component of the European Union’s space programme.

Sentinel-1B followed in 2016 but its mission ended in December 2021 after experiencing a fault that left it unable to deliver data. Sentinel-1B will soon be deorbited.

Engineers at Thales Alenia Space, the Prime Contractor for Sentinel-1, have been working tirelessly to move forward getting Sentinel-1C ready for launch.

Most recently, they have carried out tests to ensure the satellite will survive the noise and vibrations that it will have to endure during liftoff and separation from the rocket. The sequences and mechanisms that deploy the satellite’s two 10-metre-long solar wings and 12-metre-long radar antenna have also been thoroughly tested.

Along with testing it in stowed and deployed configurations, electromagnetic and radio frequency compatibility tests, and more, the satellite passed its qualification and flight acceptance review at the end of last year.

The satellite has also undergone checks to ensure that it fits correctly to its Vega-C launch adapter.

Ramón Torres, ESA’s Sentinel-1 Project Manager, said, “Our industrial team has pulled out all the stops to get Sentinel-1C to this point following the loss of Sentinel-1B. I would like to thank everybody that has been working so hard on the mission.

“We hope to hear about a new launch slot after the investigation into the failure of the Vega-C launch last December.”

“Following the launch adapter fit check, the Sentinel-1C satellite will soon be shipped from Cannes and back to Rome for short-term storage until we can then ship it to the launch site in French Guiana.”

The launch will most likely be delayed.

https://www.avio.com/press-release/zefiro-40-firing-test-preliminary-outcome

Quote
Colleferro, 29 June 2023 – Yesterday a static firing test of the Zefiro 40 motor (second stage of the Vega C launcher) was performed according to schedule as one of the requirements linked to the return to flight of Vega C after the flight anomaly suffered on the last launch VV22 in December.

Following the recommendation of the Independent Enquiry Commission on VV22, the test was performed to qualify the performance of the motor with a new carbon-carbon material for its nozzle throat. The conditions of the test were purposely set as extremely severe in terms of max motor operating pressure in order to demonstrate a large performance margin with a view to ensure maximum flight reliability.

Preliminary analysis of test results (to be further investigated in the following days/weeks before reaching definitive conclusions) allowed to reach the following results. The new carbon-carbon material showed a nominal performance, closely linked to prediction. However, after 40 seconds into the test, another anomaly was revealed, leading to a reduction in overall pressure performance of the motor before the test completion planned at 97 seconds. This aspect will require further investigation and testing activity to be conducted by Avio and the European Space Agency to ensure optimal performance conditions.

The Vega launcher is unaffected by the performance of Zefiro 40, which is specific to Vega C. Vega next launch remains planned for September. The planning for the return to flight of Vega C is currently under evaluation, pending further analysis and investigation as above mentioned. Avio remains anyway committed to leverage the Vega launcher while Vega C prepares to return to flight.

Avio will communicate further details as soon as more detailed analysis is complete.

What does that mean? Will Sentinel 1C now also be transferred to the Falcon-9?
Aside from the Sentinel-1B replacement, how long will Sentinel-1A's fuel reserves last?
Do the EU already have to think about the launch of Sentinel-1D?

Speculate that the decision to transferred has been made, but not yet announced.

EU don't want to be without an operational Sentinel-1, when the replacement is in storage in a clean room. It will be too embarrassing. ;)

Considering the Sentinel-1 satellites are built on the same bus as the COSMOS-SkyMed second generation, the process of moving it over to F9 if ESA chooses to would be assisted by the similar requirements between the missions

With Vega-C a launch will probably only be possible in a year at the earliest, I think.
A new launch order is not (publicly) known.
In addition to the Falcon 9, a launch with GSLV-MK2 would theoretically also be possible.
But in what time frame?

Incidentally, Sentinel-1C has been missing from the Arianespace launch schedule for some time.  ???

Edit: Just to add, I watched the media conference that ESA had this morning, someone did ask about this launch, and all Stephane and Josef said was that the European Commission will make that decision on where and when to launch it, and they dont really have anything more to say. ~27 minutes into the briefing.

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

This is from October 16, 2023, I didn't see it, was hidden at the bottom.
The report on the Zefiro-40 test failure was published on October 2.
So it should be known that the Vega-C will not be ready in Q1 2024.
Conclusion, there is already a launch order with "the other provider"?  ???

There has been no news since January when ESA announced that they will “be assessing all elements in the coming days and weeks. We’ll take a final decision considering a backup option of Falcon 9.”.

Then on 17 April news came of issues with the Sentinel-1a thrusters: https://sentinels.copernicus.eu/web/sentinel/-/sentinel-1a-change-in-the-orbit-control-strategy

With this ominous statement "due to issues related to the availability of launchers, S1C had to be postponed and the launch is currently planned for Q4-2024, for a start of routine operations in Q1/2-2025. At that moment, Sentinel-1A will have reached 11 years in space, far beyond its designed lifetime."
And https://sentinels.copernicus.eu/documents/d/sentinel/esa-eopg-eopgmq-tn-2024-12-increase-of-sentinel-1a-orbital-tube

I can't find the link now - but part of this news has also been a short statement on the delayed de-orbiting of S1B due to unexpectedly low performance of it's thrusters.

So... it sounds like they decided not to use Falcon and instead put the 2 year behind schedule "emergency" replacement of 1b and savior of the currently failing 1a on the return to launch on the Vega-C, one of the least reliable launch vehicles to not be flying today which can barely lift the weight to that orbit?

Our, and many other, companies in the EO / InSAR space as well as our customers depend on this system for operational monitoring and hazard detection. How has this thing not been launched 2 and a half years in? This was the promise of the Copernicus system. Anyone have some inside news?

The reasons are due to Vega-C being delayed due to launch failures, due to Soyuz being unavailable due to Russia invading Ukraine, due to Ariane 6 being delayed due to development issues and Covid and due to lack of foresight by ESA and Arianespace in not building more Ariane 5's.

Colleferro (Rome), 28 May 2024 – The Zefiro-40 solid rocket motor, the second stage of the Vega C rocket, was tested on 28 May by Vega-C prime contractor Avio at its Salto di Quirra test facility in Sardinia, Italy. The motor featured an improved engine nozzle design, required to prepare for a Vega-C return-to-flight by the end of 2024.

Initial post-test review indicates that the new nozzle assembly performed as expected throughout the scheduled 94 seconds burning time of the test, simulating a nominal in-flight performance.

The Zefiro-40 is a 7.6 m tall rocket motor, loaded with over 36 tons of solid propellant. For this test the motor was installed on its horizontal test bench. Zefiro-40 is developed and manufactured by Avio in their Colleferro factory near Rome, Italy.

A second firing test will be conducted after the summer to confirm the data collected today. Avio engineers will review the data from the first test to prepare for a second test in October that will then qualify the second stage Zefiro-40 solid rocket motor for return-to-flight by end 2024 from Europe’s Spaceport in French Guiana.

Vega-C is a 35 m high launcher with a mass at liftoff of 210 000 kg. It can place about 2300 kg into a polar orbit. Vega-C can accommodate a mix of cargo shapes and sizes, ranging from CubeSats as small as one kilogram up to a single large payload.

From Vega to Vega-C

Vega-C is the larger evolution of the Vega family of rockets. The original Vega was launched in 2012 and has flown 21 times since. The last Vega flight is scheduled this summer, after which the model will be retired and Vega-C will take over. The smaller Vega variant does not use the Zefiro-40 stage.

ESA is responsible for the Vega-C launch system qualification and also purchases launch services for European institutional missions. The Vega-C development programme was carried out with participation of thirteen ESA Member States, Austria, Belgium, the Czech Republic, France, Germany, Ireland, Italy, The Netherlands, Norway, Romania, Spain, Sweden, Switzerland. The Agency is the contracting authority for the development of Vega-C, supports both the development and exploitation, while also providing technical supervision based on its 30 years of experience.

Avio is the prime contractor and design authority of the Vega-C launchers. Arianespace is the launch service provider.

just saw, the 2nd test fire of the Z40 slipped into October. So far it has been written Q3.

To be honest, I don't understand EU's patience either. Sentinel 1A had a hard life.
A small anomaly of the Fregat led to a slightly different orbit and a very early maneuver to avoid an old satellite.
Later a hit in the solar wing.
The current thruster anomaly is already the 2nd problem with the propulsion system.

SN Europe sees Ariane 6 launch as an end to its “launcher crisis” [Jul 23, Jeff Foust]
Quote
<snip>
ESA is also preparing for the return to flight of the Vega C, grounded since a launch failure in December 2022. A separate task force is working on that effort, [Josef Aschbacher, ESA director general] said. “Since the beginning of the task force, which was the end of last year, we have not lost a single day along the schedule,” he said.

That return-to-flight mission, carrying the Senintel-1C radar imaging Earth science satellite, is scheduled to fly between mid-November and mid-December, with a more specific date to come after a second test firing of the redesigned second-stage motor at the end of September or early October.

Aschbacher said in the interview that another factor in the launch date for Vega C will be the upcoming final launch of the original version of the Vega rocket, currently set for September carrying Sentinel-2C. “There’s a certain number of weeks necessary for the ground operations and the preparations in Kourou,” the spaceport that hosts Vega and Ariane launches, he said. Any slip in that Vega launch could push back the Vega C launch, he said, even if the Vega C is itself ready to launch.

Software fix planned to correct Ariane 6 upper stage issue
Jeff Foust   September 16, 2024
...
“We could have done the second flight without correcting it,” he said, since the mission does not require multiple burns of the Vinci engine to place the satellite in its planned orbit. “But we want to deorbit the second stage during this second flight, and to deorbit the upper stage we need to correct what has happened.”
...
Israël said Arianespace is still planning to conduct the second Ariane 6 launch by the end of the year, weeks after the return to flight of the Vega C rocket currently planned for late November or early December, even with the APU software change. “We will see if we match this objective in the coming weeks and months,” he said of the schedule.

Sentinel-1C arrives in French Guiana
09/10/2024

The Sentinel-1C satellite, the third satellite of the Copernicus Sentinel-1 mission, has arrived at the European spaceport in French Guiana for liftoff on the Vega-C rocket at the end of 2024. The satellite will continue the critical task of delivering key radar imagery of Earth’s surface for a wide range of Copernicus services and scientific applications.

Following its journey from Cannes, France, via Turin, Italy, Sentinel-1C has safely landed in Kourou, French Guiana, after being transported on an Antonov aircraft. It will now undergo a series of launch preparation activities to ensure it is ready for liftoff.

Ramón Torres, Sentinel-1 Project Manager at ESA, commented, “Launching on the Vega-C return to flight is certainly a formidable challenge, but thanks to the extraordinary effort and meticulous planning by AVIO and Arianespace, the Sentinel-1 team is filled with confidence.

“The team is ensuring that no stone has been left unturned to ensure that this extraordinary satellite is launched with the utmost safety and precision. The team eagerly awaits the moment when their hard work and dedication culminate in a flawless launch, marking another milestone for the Copernicus programme.”

Simonetta Cheli, Director of Earth Observation Programmes at ESA, added, "The Sentinel-1 mission highlights the strong partnership between ESA and the European Commission to provide vital radar data that Europe relies on. With Sentinel-1C now in French Guiana, we are furthering the important work of Copernicus."

The Copernicus Sentinel-1 mission provides all-weather, day-and-night radar imagery for the global monitoring of Earth's land and oceans – supporting environmental management, disaster response and climate change research.

The Sentinel-1 mission, the first in the family of Copernicus, is based on a constellation of two identical satellites flying in the same orbit but 180° apart, to optimise global coverage and data delivery for Copernicus, the Earth observation component of the European Union’s Space Programme, managed by the European Commission.

Sentinel-1A was the first satellite in the series, launched in April 2014, followed by the launch of Sentinel-1B in 2016. The Sentinel-1B mission came to an end in December 2022 after experiencing a technical fault that rendered it unable to acquire data. The satellite has been successfully de-orbited and will re-enter Earth’s atmosphere within 25 years.

Sentinel-1C will soon take over the role of Sentinel-1B in the mission.

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
➔ 107th spacecraft built by Thales Alenia Space launched by Arianespace

First Stage for Vega C Return to Flight Arrives at Launch Pad
October 10, 2024

The P120 solid-fuel first stage that will power the Vega C rocket’s return-to-flight mission has been transferred to the ZLV launch pad at the Guiana Space Centre.

[...]

The cargo ship MN Toucan arrived in French Guiana on 19 September, carrying elements for the rocket’s return-to-flight mission. Once removed from the hull of the Toucan, the P120 first stage was transferred to the booster integration building (BIP) for unpacking and final preparation. On 3 October, the stage was transferred from the integration building to the VEGA launch zone (ZLV) and placed on the launch pad. The first interstage will be stacked next, followed by the recertified Z40 second stage with its redesigned nozzle.

Building Vega-C flight VV25 on its launch pad
15/10/2024

Earth-observer Sentinel-1C is set to launch on Vega-C rocket flight VV25. At 35 m tall, Vega-C weighs 210 tonnes on the launch pad and reaches orbit with three solid-propellant-powered stages before the fourth liquid-propellant stage takes over for precise placement of Sentinel-1C into its orbit.

Complementing the Ariane family to launch all types of payloads into their desired orbits, Vega-C ensures that Europe has versatile and independent access to space. ESA owns the Vega-C programme, working with Avio as prime contractor and design authority. Arianespace will serve as 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 independent access to space.

Carrying advanced radar technology to provide an all-weather, day-and-night supply of imagery of Earth’s surface, the ambitious Copernicus Sentinel-1 mission has raised the bar for spaceborne radar. Copernicus Sentinel-1C is the third Sentinel-1 satellite to be launched. While the European Union is at the helm of Copernicus, ESA develops, builds and launches the dedicated Sentinel satellites.

Busy week of testing for the Sentinel-1C satellite

Quote
It’s been a busy week for the Sentinel-1C satellite!

On Friday, 11 October, the team kicked things off by pressurising the satellite’s fuel tank with nitrogen to check for any leaks in the valves or tank.

After de-pressurising it the next day, they confirmed everything was in great shape! Since working with fuel can be hazardous, only essential staff were allowed in the clean room during this process.

By Monday, the satellite team moved on to functional tests, running checks on all the subsystems.

AIS antennas installed on Sentinel-1C

Quote
Functional testing is ongoing at Europe’s spaceport for the upcoming launch of the Copernicus Sentinel-1C satellite.

The Automated Identification System (AIS) antennas were fully installed on the spacecraft.

These box-shaped structures, located at each corner of the SAR Central Panel, were temporarily removed for transport to protect the antennas from potential damage.

These antennas are components of the AIS Instrument, which identifies ships appearing as white dots in SAR images. Now, they have been fully remounted and tested, allowing functional testing to proceed at spacecraft level.

The fourth stage of the Vega-C rocket, destined for the VV25 flight carrying the Sentinel-1C Earth observation satellite, has been successfully lifted and positioned onto the third stage.

In the images, we can see the transport of the fourth stage to the launch platform. This module, known as AVUM+, incorporates several enhancements compared to the fourth stage of Vega, the predecessor of Vega-C. These improvements include a "sandwich" structure with a composite coating, an increased propellant capacity, and the main engine's re-ignition capability, offering Vega-C greater flexibility for multi-payload missions.

Thankyou. I thought I'd missed it. 45 minutes after the scheduled launch and after some searching I finally got an update.

Was there a slight underperformance or thrust vector "observation" with the Zefiro-9 (Z9), or might the deviation of the yellow actual trajectory from the green target trajectory be related to the data drop-out?

Double win for Europe: Sentinel-1C and Vega-C take to the skies

Quote
Sentinel-1C was launched into orbit on 5 December, lifting off aboard Vega-C at 22:20 CET (18:20 local time). The launch proceeded smoothly, with the rocket reaching space in eight minutes and dropping off Sentinel-1C at approximately 00:04 CET.

The launcher’s mission, called VV25, is a return-to-flight for Vega-C – Europe’s lightweight, high-performance rocket – marking the restart of routine commercial operations for the new launcher. At 00:12 CET, ESA established communication with the satellite confirming that it was safely in orbit.
