Question:  Would this new Kassav automated termination system have terminated the AV241 flight in January?
No. The red box for Kassav is larger than the current one.
Also, Kassav is taking into account vehicle "health".

Yes it would have terminated the flight. Flying over the beach at Kourou is not an option.

So is there a finally a report saying that the flight meet the destruct criteria?
Or is that still a common sense opinion?

We know from the Falcon 9 accidents, that a rocket can explode at any time without any warning. Letting it fly over (or close to) inhabited area just because there is currently no issue with the launcher, is not safe.

It just shows that CNES was (or still is?) not taking ground safety seriously at CSG.

Destruct isn't exactly perfectly safe either though, especially with solids (what happens if an SRB doesn't blow up, and is now flying uncontrolled? Thats way worse than an off-nominal but functioning rocket). Whats the debris radius from that sort of explosion anyway? There will be some time where that radius passes over the populated area in question, can the anomaly be detected and an abort triggered before that happens? If so, then abort is the correct decision. If the debris zone is *currently* over people, given a rocket as otherwise reliable as Ariane 5 you're probably better off letting it do its thing. And after the debris zone has passed over (assuming there is only 1 inhabited area being crossed, which IIRC was the case on that mission), theres not really any risk from letting the launch continue anyway

Arianespace to launch the CSO-3 satellite with Ariane 6 for France’s CNES and DGA
Arianespace has signed the third CSO satellite’s launch services contract with the French CNES space agency.

Arianespace today announced the launch services contract signature with CNES for the CSO-3 satellite, which will be launched aboard the future Ariane 6 launch vehicle – in its A62 version – from the Guiana Space Center. This option already was included in the previously-signed launch contract for the CSO-1 and CSO-2 satellites on missions using the Soyuz launcher.

The CSO (Composante Spatiale Optique) is a very-high-resolution satellite system comprising several new-generation optical detection satellites. It is a follow-on to the current Helios II system, and will ensure the continuity of French intelligence based on very-high-definition images, while also improving detection capabilities.

The CSO system is being developed within the scope of MUSIS (Multinational Space-based Imaging System), a program conducted by the DGA (Direction Générale de l’Armement), which chose CNES as contracting authority to procure the satellites and launch services.

CNES also is prime contractor for the mission control and programming center, along with the satellites’ orbital positioning and routine operations, while the DGA is in charge of supplying the ground segment. CNES and the DGA are working as an integrated team in overseeing system integration.

CNES chose Airbus Defence and Space to build the satellites, with Thales Alenia Space producing the optical imaging instruments.

Following the contract signature, Stéphane Israël, Arianespace Chief Executive Officer said: “ We are very honored that the DGA and CNES have entrusted us with the launch of CSO-3 using our future Ariane 6 launcher. This latest institutional mission – the first for which France has chosen Ariane 6 – marks a further step forward in the confirmation of this new launcher for European institutional users.”

Ariane 6 accelerates as Arianespace signs first commercial GEO multiple-launch contract, plus a new institutional mission
World Satellite Business Week 2018


Arianespace is present at World Satellite Business Week (WSBW) from September 10 to 14 in Paris, confirming the attractiveness of its launcher family with the announcement of two contracts for Ariane 6: the first with Eutelsat as part of a launch services agreement involving five satellites; and the second with France’s CNES space agency and the country’s DGA defense procurement agency for the CSO-3 satellite. A third contract also was signed recently with the Indian Space Research Organization (ISRO) for Ariane 5 missions to orbit two satellites.

Arianespace’s backlog is now 59 launches to be carried out during the coming years, including three on Vega C and five on Ariane 6 – the new launchers slated to make their maiden flights in 2019 and 2020, respectively.

Stéphane Israël, Chief Executive Officer of Arianespace, will participate in the WSBW roundtable entitled: “Accelerating Access to Space” on Tuesday, September 11 at 4:00 p.m.

First multi-launch commercial contract with GEO satellites for Ariane 6, along with its third institutional mission

As World Satellite Business Week opened its doors, Arianespace and Eutelsat announced the signature of a multi-year multiple-launch agreement concerning five satellites to be launched through 2027, making Eutelsat the first commercial Ariane 6 customer with geostationary orbit satellite payloads. For institutional missions, after the two launch contracts signed in 2017 for the European Commission and ESA’s Galileo constellation, CNES and the DGA have chosen the A62 version of Ariane 6 (with two boosters) to launch their CSO-3 satellite. These orders clearly reflect the competitiveness and versatility of Ariane 6, which will be available in two versions to handle all orbits and multiple payload configurations under the fairing.

Ariane 5 also confirmed its continued attractiveness, as Arianespace signed a contract with India’s ISRO space agency for the launch of two geostationary satellites: GSAT-30 and GSAT-31.

In total, and taking into account the signing of a contract with B-SAT during the first half of 2018 to launch BSAT-4b with Ariane 5 – as well as several contracts for the Proof of Concept (POC) flight of the Small Satellite Launch System (SSMS) on Vega – Arianespace’s order book value has reached more than €4.9 billion. This corresponds to 59 launches: 17 Ariane 5s, five with Ariane 6, 28 with Soyuz and nine with Vega/Vega C.

With nearly one-third of these launches for the European institutions, Arianespace reaffirms its mission to provide Europe with reliable and independent access to space while also confirming its export success.

A contract also is expected to be signed with the South Korean space agency (KARI) on September 20 in Daejeon for a satellite to be lofted by Vega C.

13 satellites orbited by Ariane, Soyuz and Vega since January 2018

Arianespace has carried out five launches since the start of 2018 for both institutional and commercial customers, clearly reflecting the versatility of its launcher family and services. The 13 satellites launched weighed a cumulated total of 25 metric tons and they are performing communications, navigation, science and Earth observation missions. From January to August 2018:

Three Ariane 5 launchers orbited four geostationary communications satellites for SES, Yahsat, Avanti Communications and SKY Perfect JSAT/Japanese Ministry of Defense, along with four satellites in the Galileo navigation constellation for the European Commission and ESA,
A Soyuz orbited four satellites in SES’s O3b constellation, and
A Vega launched ESA’s Aeolus science satellite, which will support sustainable development.
Six more launches are scheduled during the remaining four months of the year, with two upcoming missions being highly symbolic:

The 100th Ariane 5 launch, scheduled for September 25, will loft Horizons 3e for Intelsat and SKY Perfect JSAT, and Azerspace-2/Intelsat 38 for Azercosmos and Intelsat.
BepiColombo, a mission to explore the planet Mercury, for ESA in partnership with the Japanese space agency (JAXA), to be launched by an Ariane 5 on October 19.
Ariane 6 and Vega C: getting closer!

Development of the new members of Arianespace’s launcher family is proceeding apace, with first missions planned in 2019 for Vega C and 2020 for Ariane 6. A milestone took place on July 16 with a successful first hot firing test of the P120C solid rocket motor, which will equip the strap-on boosters for Ariane 62 and Ariane 64, as well as Vega C’s first stage. This followed a series of successful tests of the Vulcain 2.1 main stage engine and Vinci upper stage engine for Ariane 6, along with progress toward Maturity Gate 7 (the critical design review) – which is planned by year-end.

European institutions also have reached major milestones in their commitment to Ariane 6 and Vega C. After the European Commission announced its proposed ambitious space budget for the upcoming decade, an ESA Council meeting in June confirmed funding for the transition period between Ariane 5 and Ariane 6. In addition to the four government contracts already signed for Europe’s new launchers (three for Ariane 6 and one for Vega C), the commitment of European governments to all missions identified during the transition phase is a key to the sustainable success of these launchers.

Eutelsat signs long-term multiple-launch service agreement with Arianespace

Paris, 10 September 2018 – Arianespace and Eutelsat Communications (NYSE Euronext Paris: ETL) have concluded a long-term multiple-launch service agreement on the occasion of the World Satellite Business Week in Paris.

The agreement covers five launches until 2027 and will provide Eutelsat with assured access to space with schedule flexibility at cost effective prices. With this agreement, Eutelsat is the first commercial customer to sign up to Ariane 6, Arianespace’s next-generation launch vehicle, expected to start service from 2020.

This new long-term commitment builds on the previous contract signed by Eutelsat and Arianespace in February 2013, which was expanded in 2017. Under these earlier agreements, three future Eutelsat satellites, EUTELSAT 7C, EUTELSAT QUANTUM and KONNECT, are already scheduled for launch on Ariane 5.

Rodolphe Belmer, CEO of Eutelsat Communications, said: “We are proud to be the first operator to commit to Ariane 6. This emblematic European programme will further enhance our ability to gain access to space in a timely, competitive and reliable manner. It strengthens our relationship with our long-standing partner, Arianespace, which has already been entrusted with the launch of half of our fleet. Furthermore, it illustrates the key role of Eutelsat in the development of the space sector, while underpinning our commitment to enhancing the efficiency of our satellite programmes.”

Stéphane Israël, CEO of Arianespace added: "We are delighted that Eutelsat has chosen Arianespace to launch five of its upcoming satellites, in addition to the three already in our order book. With this multi-launch agreement, Eutelsat becomes the first commercial customer for Ariane 6. I would like to extend my warm thanks to Eutelsat for their confidence in Arianespace and our Ariane 6 launch vehicle. At the same time, their selection clearly shows Arianespace’s ability to offer our customers long-term partnerships and increasingly flexible solutions.”
